The list of maintainers for a project is defined by the project `CODEOWNERS` file placed at the top-level of each project's repository.
Project maintainers are managed via GitHub teams. The maintainer team for a project is referenced in the `CODEOWNERS` file
at the top level of each project repository.
### Becoming a project maintainer
Existing maintainers may decide to elevate a *Contributor* to the *Maintainer* role based on the contributor established trust and contributions relevance.
This decision process is not formally defined and is based on lazy consensus from the existing maintainers.
Any contributor may request for becoming a project maintainer by opening a pull request (PR) against the `CODEOWNERS` file, and adding *all* current maintainers as reviewer of the PR.
Maintainers may also pro-actively promote contributors based on their contributions and leadership track record.
A contributor can propose themself or someone else as a maintainer by opening an issue in the repository for the project in question.
### Removing project maintainers
Inactive maintainers can be removed by the Steering Committee.
Maintainers are considered inactive if they have made no GitHub contributions relating to the project they maintain
for more than six months.
Before removing a maintainer, the Steering Commitee should notify the maintainer of their status.
Not all inactive maintainers must be removed.
This process should mainly be used to remove maintainers that have permanently moved on from the project.

# Running a workload
## Creating a sample CoCo workload
Once you've used the operator to install Confidential Containers, you can run a pod with CoCo by simply adding a runtime class.
First, we will use the `kata-qemu-coco-dev` runtime class which uses CoCo without hardware support.
Initially we will try this with an unencrypted container image.
In this example, we will be using the bitnami/nginx image as described in the following yaml:
```yaml
apiVersion: v1
kind: Pod
metadata:
labels:
run: nginx
name: nginx
annotations:
io.containerd.cri.runtime-handler: kata-qemu-coco-dev
spec:
containers:
- image: bitnami/nginx:1.22.0
name: nginx
dnsPolicy: ClusterFirst
runtimeClassName: kata-qemu-coco-dev
```
Setting the `runtimeClassName` is usually the only change needed to the pod yaml, but some platforms
support additional annotations for configuring the enclave. See the [guides](../guides) for
more details.
With Confidential Containers, the workload container images are never downloaded on the host.
For verifying that the container image doesnt exist on the host, you should log into the k8s node and ensure the following command returns an empty result:
```shell
root@cluster01-master-0:/home/ubuntu# crictl -r unix:///run/containerd/containerd.sock image ls | grep bitnami/nginx
```
You will run this command again after the container has started.
Create a pod YAML file as previously described (we named it `nginx.yaml`) .
Create the workload:
```shell
kubectl apply -f nginx.yaml
```
Output:
```shell
pod/nginx created
```
Ensure the pod was created successfully (in running state):
```shell
kubectl get pods
```
Output:
```shell
NAME READY STATUS RESTARTS AGE
nginx 1/1 Running 0 3m50s
```
Now go back to the k8s node and ensure that you dont have any bitnami/nginx images on it:
```shell
root@cluster01-master-0:/home/ubuntu# crictl -r unix:///run/containerd/containerd.sock image ls | grep bitnami/nginx
```
## Encrypted and/or signed images with attestation
The previous example does not involve any attestation because the workload container isn't signed or encrypted,
and the workload itself does not require any secrets.
This is not the case for most real workloads. It is recommended to use CoCo with signed and/or encrypted images.
The workload itself can also request secrets from the attestation agent in the guest.
Secrets are provisioned to the guest in conjunction with an attestation, which is based on hardware evidence.
The rest of this guide focuses on setting up more substantial encrypted/signed workloads using attestation
and confidential hardware.
CoCo has a modular attestation interface and there are a few options for attestation.
CoCo provides a generic Key Broker Service (KBS) that the rest of this guide will be focused on.
### Select Runtime Class
To use CoCo with confidential hardware, first switch to the appropriate runtime class.
TDX has one runtime class, `kata-qemu-tdx`.
For SNP, use the `kata-qemu-snp` runtime class and follow the [SNP guide](https://confidentialcontainers.org/docs/examples/snp-container-launch/).
For `enclave-cc` follow the [enclave-cc guide](../guides/enclave-cc.md).
### Deploy and Configure tenant-side CoCo Key Broker System cluster
The following describes how to run and provision the generic KBS.
The KBS should be run in a trusted environment. The KBS is not just one service,
but a combination of several.
A tenant-side CoCo Key Broker System cluster includes:
- Key Broker Service (KBS): Brokering service for confidential resources.
- Attestation Service (AS): Verifier for remote attestation.
- Reference Value Provider Service (RVPS): Provides reference values for AS.
- CoCo Keyprovider: Component to encrypt the images following ocicrypt spec.
To quick start the KBS cluster, a `docker compose` yaml is provided to launch.
```shell
# Clone KBS git repository
git clone https://github.com/confidential-containers/trustee.git
cd trustee/kbs
export KBS_DIR_PATH=$(pwd)
# Generate a user auth key pair
openssl genpkey -algorithm ed25519 > config/private.key
openssl pkey -in config/private.key -pubout -out config/public.pub
cd ..
# Start KBS cluster
docker compose up -d
```
If configuration of KBS cluster is required, edit the following config files and restart the KBS cluster with `docker compose`:
- `$KBS_DIR_PATH/config/kbs-config.toml`: configuration for Key Broker Service.
- `$KBS_DIR_PATH/config/as-config.json`: configuration for Attestation Service.
- `$KBS_DIR_PATH/config/sgx_default_qcnl.conf`: configuration for Intel TDX/SGX verification. See [details](https://github.com/confidential-containers/trustee/blob/main/attestation-service/docs/grpc-as.md#quick-start).
When KBS cluster is running, you can modify the policy file used by AS policy engine ([OPA](https://www.openpolicyagent.org/)) at any time:
- `$KBS_DIR_PATH/data/attestation-service/opa/default.rego`: Policy file for evidence verification of AS, refer to [AS Policy Engine](https://github.com/confidential-containers/attestation-service#policy-engine) for more infomation.
### Encrypting an Image
[skopeo](https://github.com/containers/skopeo) is required to encrypt the container image.
Follow the [instructions](https://github.com/containers/skopeo/blob/main/install.md) to install `skopeo`.
If building with Ubuntu 22.04, make sure to follow the instructions to build skopeo from source, otherwise
there will be errors regarding version incompatibility between ocicrypt and skopeo. Make sure the downloaded
skopeo version is at least 1.16.0. Ubuntu 22.04 builds skopeo with an outdated ocicrypt version, which does
not support the keyprovider protocol we depend on.
Use `skopeo` to encrypt an image on the same node of the KBS cluster (use busybox:latest for example):
```shell
# edit ocicrypt.conf
tee > ocicrypt.conf <<EOF
{
"key-providers": {
"attestation-agent": {
"grpc": "127.0.0.1:50000"
}
}
}
EOF
# encrypt the image
OCICRYPT_KEYPROVIDER_CONFIG=ocicrypt.conf skopeo copy --insecure-policy --encryption-key provider:attestation-agent docker://library/busybox oci:busybox:encrypted
```
The image will be encrypted, and things happens in the KBS cluster background include:
- CoCo Keyprovider generates a random key and a key-id. Then encrypts the image using the key.
- CoCo Keyprovider registers the key with key-id into KBS.
Then push the image to a registry:
```shell
skopeo copy oci:busybox:encrypted [SCHEME]://[REGISTRY_URL]:encrypted
```
Be sure to replace `[SCHEME]` with registry scheme type like `docker`, replace `[REGISTRY_URL]` with the desired registry URL like `docker.io/encrypt_test/busybox`.
### Signing an Image
[cosign](https://github.com/sigstore/cosign) is required to sign the container image. Follow the instructions here to install `cosign`:
To install cosign, find and unpackage the corresponding package to the machine being used from their [release page](https://github.com/sigstore/cosign/releases).
Generate a cosign key pair and register the public key to KBS storage:
```shell
cosign generate-key-pair
mkdir -p $KBS_DIR_PATH/data/kbs-storage/default/cosign-key && cp cosign.pub $KBS_DIR_PATH/data/kbs-storage/default/cosign-key/1
```
Sign the encrypted image with cosign private key:
```shell
cosign sign --key cosign.key [REGISTRY_URL]:encrypted
```
Be sure to replace `[REGISTRY_URL]` with the desired registry URL of the encrypted image generated in previous steps.
Then edit an image pulling validation policy file.
Here is a sample policy file `security-policy.json`:
```json
{
"default": [{"type": "reject"}],
"transports": {
"docker": {
"[REGISTRY_URL]": [
{
"type": "sigstoreSigned",
"keyPath": "kbs:///default/cosign-key/1"
}
]
}
}
}
```
Be sure to replace `[REGISTRY_URL]` with the desired registry URL of the encrypted image.
Register the image pulling validation policy file to KBS storage:
```shell
mkdir -p $KBS_DIR_PATH/data/kbs-storage/default/security-policy
cp security-policy.json $KBS_DIR_PATH/data/kbs-storage/default/security-policy/test
```
### Deploy an Encrypted Image as a CoCo workload on CC HW
Here is a sample yaml for encrypted image deploying:
```shell
cat << EOT | tee encrypted-image-test-busybox.yaml
apiVersion: v1
kind: Pod
metadata:
labels:
run: encrypted-image-test-busybox
name: encrypted-image-test-busybox
annotations:
io.containerd.cri.runtime-handler: [RUNTIME_CLASS]
spec:
containers:
- image: [REGISTRY_URL]:encrypted
name: busybox
dnsPolicy: ClusterFirst
runtimeClassName: [RUNTIME_CLASS]
EOT
```
Be sure to replace `[REGISTRY_URL]` with the desired registry URL of the encrypted image generated in previous step, replace `[RUNTIME_CLASS]` with kata runtime class for CC HW.
Then configure `/opt/confidential-containers/share/defaults/kata-containers/configuration-<RUNTIME_CLASS_SUFFIX>.toml` to add `agent.aa_kbc_params=cc_kbc::<KBS_URI>` to kernel parameters. Here `RUNTIME_CLASS_SUFFIX` is something like `qemu-coco-dev`, `KBS_URI` is the address of Key Broker Service in KBS cluster like `http://123.123.123.123:8080`.
Deploy encrypted image as a workload:
```shell
kubectl apply -f encrypted-image-test-busybox.yaml
```

EAA is used to perform attestation at runtime and provide guest with confidential resources such as keys.
It is based on [rats-tls](https://github.com/inclavare-containers/rats-tls).
[Verdictd](https://github.com/inclavare-containers/verdictd) is the Key Broker Service and Attestation Service of EAA.
The EAA KBC is an optional module in the attestation-agent at compile time,
which can be used to communicate with Verdictd.
The communication is established on the encrypted channel provided by rats-tls.
EAA can now be used on Intel TDX and Intel SGX platforms.
## Create encrypted image
Before build encrypted image, you need to make sure Skopeo and Verdictd(EAA KBS) have been installed:
- [Skopeo](https://github.com/containers/skopeo): the command line utility to perform encryption operations.
- [Verdictd](https://github.com/inclavare-containers/verdictd): EAA Key Broker Service and Attestation Service.
1. Pull unencrypted image.
Here use `alpine:latest` for example:
```sh
${SKOPEO_HOME}/bin/skopeo copy --insecure-policy docker://docker.io/library/alpine:latest oci:busybox
```
2. Follow the [Verdictd README #Generate encrypted container image](https://github.com/inclavare-containers/verdictd#generate-encrypted-container-image) to encrypt the image.
3. Publish the encrypted image to your registry.
## Deploy encrypted image
1. Build rootfs with EAA component:
Specify `AA_KBC=eaa_kbc` parameters when using kata-containers `rootfs.sh` scripts to create rootfs.
2. Launch Verdictd
Verdictd performs remote attestation at runtime and provides the key needed to decrypt the image.
It is actually both Key Broker Service and Attestation Service of EAA.
So when deploy the encrypted image, Verdictd is needed to be launched:
```sh
verdictd --listen <$ip>:<$port> --mutual
```
> **Note** The communication between Verdictd and EAA KBC is based on rats-tls,
so you need to confirm that [rats-tls](https://github.com/inclavare-containers/rats-tls) has been correctly installed in your running environment.
3. Agent Configuration
Add configuration `aa_kbc_params= 'eaa_kbc::<$IP>:<$PORT>'` to agent config file, the IP and PORT should be consistent with verdictd.

# SEV-ES Guide
Confidential Containers supports SEV(-ES) with pre-attestation using
[simple-kbs](https://github.com/confidential-containers/simple-kbs).
This guide covers platform-specific setup for SEV(-ES) and walks through
complete flows for attestation and encrypted images.
## Creating a CoCo workload using a pre-existing encrypted image on SEV
### Platform Setup
To enable SEV on the host platform, first ensure that it is supported. Then follow these instructions to enable SEV:
[AMD SEV - Prepare Host OS](https://github.com/AMDESE/AMDSEV#prepare-host-os)
### Install sevctl and Export SEV Certificate Chain
[sevctl](https://github.com/virtee/sevctl) is the SEV command line utility and is needed to export the SEV certificate chain.
Follow these steps to install `sevctl`:
* Debian / Ubuntu:
```
# Rust must be installed to build
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
sudo apt install -y musl-dev musl-tools
# Additional packages are required to build
sudo apt install -y pkg-config libssl-dev asciidoctor
# Clone the repository
git clone https://github.com/virtee/sevctl.git
# Build
(cd sevctl && cargo build)
```
* CentOS / Fedora / RHEL:
```
sudo dnf install sevctl
```
> **Note** Due to [this bug](https://bugzilla.redhat.com/show_bug.cgi?id=2037963) on sevctl for RHEL and Fedora you might need to build the tool from sources to pick the fix up.
If using the SEV kata configuration template file, the SEV certificate chain must be placed in `/opt/sev`. Export the SEV certificate chain using the following commands:
```
sudo mkdir -p /opt/sev
sudo ./sevctl/target/debug/sevctl export --full /opt/sev/cert_chain.cert
```
### Setup and Run the simple-kbs
By default, the `kata-qemu-sev` runtime class uses pre-attestation with the
`online-sev-kbc` and [simple-kbs](https://github.com/confidential-containers/simple-kbs) to attest the guest and provision secrets.
`simple-kbs` is a basic prototype key broker which can validate a guest measurement according to a specified policy and conditionally release secrets.
To use encrypted images, signed images, or authenticated registries with SEV, you should setup `simple-kbs`.
If you simply want to run an unencrypted container image, you can disable pre-attestation by adding the following annotation
`io.katacontainers.config.pre_attestation.enabled: "false"` to your pod.
If you are using pre-attestation, you will need to add an annotation to your pod configuration which contains the URI of a `simple-kbs` instance.
This annotation should be of the form `io.katacontainers.config.pre_attestation.uri: "<KBS IP>:44444"`.
Port 44444 is the default port per the directions below, but it may be configured to use another port.
The KBS IP must be accessible from inside the guest.
Usually it should be the public IP of the node where `simple-kbs` runs.
The SEV policy can also be set by adding `io.katacontainers.config.sev.policy: "<SEV POLICY>"` to your pod configuration. The default policy for SEV and SEV-ES are, respectively, "3" and "7", where the following bits are enabled:
| Bit| Name| Description |
| --- | --- | --- |
|0|NODBG| Debugging of the guest is disallowed |
|1|NOKS| Sharing keys with other guests is disallowed |
|2|ES| SEV-ES is required |
For more information about SEV policy, see chapter 3 of the [Secure Encrypted Virtualization API](https://www.amd.com/system/files/TechDocs/55766_SEV-KM_API_Specification.pdf) (PDF).
>Note: the SEV policy is not the same as the policies that drive `simple-kbs`.
The CoCo project has created a sample encrypted container image ([ghcr.io/confidential-containers/test-container:encrypted](https://github.com/orgs/confidential-containers/packages/container/test-container/82546314?tag=encrypted)). This image is encrypted using a key that comes already provisioned inside the `simple-kbs` for ease of testing. No `simple-kbs` policy is required to get things running.
The image encryption key and key for SSH access have been attached to the CoCo sample encrypted container image as docker labels. This image is meant for TEST purposes only as these keys are published publicly. In a production use case, these keys would be generated by the workload administrator and kept secret. For further details, see the section how to [Create an Encrypted Image](#create-an-encrypted-image).
To learn more about creating custom policies, see the section on [Creating a simple-kbs Policy to Verify the SEV Firmware Measurement](#creating-a-simple-kbs-policy-to-verify-the-sev-firmware-measurement).
`docker compose` is required to run the `simple-kbs` and its database in docker containers. Installation instructions are available on [Docker's website](https://docs.docker.com/compose/install/linux/).
Clone the repository for specified tag:
```
simple_kbs_tag="0.1.1"
git clone https://github.com/confidential-containers/simple-kbs.git
(cd simple-kbs && git checkout -b "branch_${simple_kbs_tag}" "${simple_kbs_tag}")
```
Run the service with `docker compose`:
```
(cd simple-kbs && sudo docker compose up -d)
```
### Launch the Pod and Verify SEV Encryption
Here is a sample kubernetes service yaml for an encrypted image:
```
kind: Service
apiVersion: v1
metadata:
name: encrypted-image-tests
spec:
selector:
app: encrypted-image-tests
ports:
- port: 22
---
kind: Deployment
apiVersion: apps/v1
metadata:
name: encrypted-image-tests
spec:
selector:
matchLabels:
app: encrypted-image-tests
template:
metadata:
labels:
app: encrypted-image-tests
annotations:
io.containerd.cri.runtime-handler: kata-qemu-sev
spec:
runtimeClassName: kata-qemu-sev
containers:
- name: encrypted-image-tests
image: ghcr.io/fitzthum/encrypted-image-tests:encrypted
imagePullPolicy: Always
```
Save this service yaml to a file named `encrypted-image-tests.yaml`. Notice the image URL specified points to the previously described CoCo sample encrypted container image. `kata-qemu-sev` must also be specified as the `runtimeClassName`.
Start the service:
```
kubectl apply -f encrypted-image-tests.yaml
```
Check for pod errors:
```
pod_name=$(kubectl get pod -o wide | grep encrypted-image-tests | awk '{print $1;}')
kubectl describe pod ${pod_name}
```
If there are no errors, a CoCo encrypted container with SEV has been successfully launched!
### Verify SEV Memory Encryption
The container `dmesg` report can be parsed to verify SEV memory encryption.
Get pod IP:
```
pod_ip=$(kubectl get pod -o wide | grep encrypted-image-tests | awk '{print $6;}')
```
Get the CoCo sample encrypted container image SSH access key from docker image label and save it to a file.
Currently the docker client cannot pull encrypted images. We can inspect the unencrypted image instead,
which has the same labels. You could also use `skopeo inspect` to get the labels from the encrypted image.
```
docker pull ghcr.io/fitzthum/encrypted-image-tests:unencrypted
docker inspect ghcr.io/fitzthum/encrypted-image-tests:unencrypted | \
jq -r '.[0].Config.Labels.ssh_key' \
| sed "s|\(-----BEGIN OPENSSH PRIVATE KEY-----\)|\1\n|g" \
| sed "s|\(-----END OPENSSH PRIVATE KEY-----\)|\n\1|g" \
> encrypted-image-tests
```
Set permissions on the SSH private key file:
```
chmod 600 encrypted-image-tests
```
Run a SSH command to parse the container `dmesg` output for SEV enabled messages:
```
ssh -i encrypted-image-tests \
-o "StrictHostKeyChecking no" \
-t root@${pod_ip} \
'dmesg | grep SEV'
```
The output should look something like this:
```
[ 0.150045] Memory Encryption Features active: AMD SEV
```
## Create an Encrypted Image
If SSH access to the container is desired, create a keypair:
```
ssh-keygen -t ed25519 -f encrypted-image-tests -P "" -C "" <<< y
```
The above command will save the keypair in a file named `encrypted-image-tests`.
Here is a sample Dockerfile to create a docker image:
```
FROM alpine:3.16
# Update and install openssh-server
RUN apk update && apk upgrade && apk add openssh-server
# Generate container ssh key
RUN ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key -P ""
# A password needs to be set for login to work. An empty password is
# unproblematic as password-based login to root is not allowed.
RUN passwd -d root
# Copy the remote generated public key to the container authorized_keys
# Generate with 'ssh-keygen -t ed25519 -f encrypted-image-tests -P "" -C ""'
COPY encrypted-image-tests.pub /root/.ssh/authorized_keys
# Entry point - run sshd
ENTRYPOINT /usr/sbin/sshd -D
```
Store this `Dockerfile` in the same directory as the `encrypted-image-tests` ssh keypair.
Build image:
```
docker build -t encrypted-image-tests .
```
Tag and upload this unencrypted docker image to a registry:
```
docker tag encrypted-image-tests:latest [REGISTRY_URL]:unencrypted
docker push [REGISTRY_URL]:unencrypted
```
Be sure to replace `[REGISTRY_URL]` with the desired registry URL.
[skopeo](https://github.com/containers/skopeo) is required to encrypt the container image. Follow the instructions here to install `skopeo`:
[skopeo Installation](https://github.com/containers/skopeo/blob/main/install.md)
The Attestation Agent hosts a grpc service to support encrypting the image. Clone the repository:
```
attestation_agent_tag="v0.1.0"
git clone https://github.com/confidential-containers/attestation-agent.git
(cd attestation-agent && git checkout -b "branch_${attestation_agent_tag}" "${attestation_agent_tag}")
```
Run the offline_fs_kbs:
```
(cd attestation-agent/sample_keyprovider/src/enc_mods/offline_fs_kbs \
&& cargo run --release --features offline_fs_kbs -- --keyprovider_sock 127.0.0.1:50001 &)
```
Create the Attestation Agent keyprovider:
```
cat > attestation-agent/sample_keyprovider/src/enc_mods/offline_fs_kbs/ocicrypt.conf <<EOF
{
"key-providers": {
"attestation-agent": {
"grpc": "127.0.0.1:50001"
}}}
EOF
```
Set a desired value for the encryption key that should be a 32-bytes and base64 encoded value:
```
enc_key="RcHGava52DPvj1uoIk/NVDYlwxi0A6yyIZ8ilhEX3X4="
```
Create a Key file:
```
cat > keys.json <<EOF
{
"key_id1":"${enc_key}"
}
EOF
```
Run skopeo to encrypt the image created in the previous section:
```
sudo OCICRYPT_KEYPROVIDER_CONFIG=$(pwd)/attestation-agent/sample_keyprovider/src/enc_mods/offline_fs_kbs/ocicrypt.conf \
skopeo copy --insecure-policy \
docker:[REGISTRY_URL]:unencrypted \
docker:[REGISTRY_URL]:encrypted \
--encryption-key provider:attestation-agent:$(pwd)/keys.json:key_id1
```
Again, be sure to replace `[REGISTRY_URL]` with the desired registry URL.
`--insecure-policy` flag is used to connect to the attestation agent and will not impact the security of the project.
Make sure to use the `docker` prefix in the source and destination URL when running the `skopeo copy` command as demonstrated above.
Utilizing images via the local `docker-daemon` is known to have issues, and the `skopeo copy` command does not return an adequate error
response. A remote registry known to support encrypted images like GitHub Container Registry (GHCR) is required.
At this point it is a good idea to inspect the image was really encrypted as skopeo can silently leave it unencrypted. Use
`skopeo inspect` as shown below to check that the layers MIME types are **application/vnd.oci.image.layer.v1.tar+gzip+encrypted**:
```
skopeo inspect docker-daemon:[REGISTRY_URL]:encrypted
```
Push the encrypted image to the registry:
```
docker push [REGISTRY_URL]:encrypted
```
`mysql-client` is required to insert the key into the `simple-kbs` database. `jq` is required to json parse responses on the command line.
* Debian / Ubuntu:
```
sudo apt install mysql-client jq
```
* CentOS / Fedora / RHEL:
```
sudo dnf install [ mysql | mariadb | community-mysql ] jq
```
The `mysql-client` package name may differ depending on OS flavor and version.
The `simple-kbs` uses default settings and credentials for the MySQL database. These settings can be changed by the `simple-kbs` administrator and saved into a credential file. For the purposes of this quick start, set them in the environment for use with the MySQL client command line:
```
KBS_DB_USER="kbsuser"
KBS_DB_PW="kbspassword"
KBS_DB="simple_kbs"
KBS_DB_TYPE="mysql"
```
Retrieve the host address of the MySQL database container:
```
KBS_DB_HOST=$(docker network inspect simple-kbs_default \
| jq -r '.[].Containers[] | select(.Name | test("simple-kbs[_-]db.*")).IPv4Address' \
| sed "s|/.*$||g")
```
Add the key to the `simple-kbs` database without any verification policy:
```
mysql -u${KBS_DB_USER} -p${KBS_DB_PW} -h ${KBS_DB_HOST} -D ${KBS_DB} <<EOF
REPLACE INTO secrets VALUES (10, 'key_id1', '${enc_key}', NULL);
REPLACE INTO keysets VALUES (10, 'KEYSET-1', '["key_id1"]', NULL);
EOF
```
The second value in the keysets table (`KEYSET-1`) must match the `guest_pre_attestation_keyset` value specified in the SEV kata configuration file located here:
`/opt/confidential-containers/share/defaults/kata-containers/configuration-qemu-sev.toml`
Return to step [Launch the Pod and Verify SEV Encryption](#launch-the-pod-and-verify-sev-encryption) and finish the remaining process. Make sure to change the `encrypted-image-tests.yaml` to reflect the new `[REGISTRY_URL]`.
To learn more about creating custom policies, see the section on [Creating a simple-kbs Policy to Verify the SEV Firmware Measurement](#creating-a-simple-kbs-policy-to-verify-the-sev-guest-firmware-measurement).
## Creating a simple-kbs Policy to Verify the SEV Guest Firmware Measurement
The `simple-kbs` can be configured with a policy that requires the kata shim to provide a matching SEV guest firmware measurement to release the key for decrypting the image. At launch time, the kata shim will collect the SEV guest firmware measurement and forward it in a key request to the `simple-kbs`.
These steps will use the CoCo sample encrypted container image, but the image URL can be replaced with a user created image registry URL.
To create the policy, the value of the SEV guest firmware measurement must be calculated.
`pip` is required to install the `sev-snp-measure` utility.
* Debian / Ubuntu:
```
sudo apt install python3-pip
```
* CentOS / Fedora / RHEL:
```
sudo dnf install python3
```
[sev-snp-measure](https://github.com/IBM/sev-snp-measure) is a utility used to calculate the SEV guest firmware measurement with provided ovmf, initrd, kernel and kernel append input parameters. Install it using the following command:
```
sudo pip install sev-snp-measure
```
The path to the guest binaries required for measurement is specified in the kata configuration. Set them:
```
ovmf_path="/opt/confidential-containers/share/ovmf/OVMF.fd"
kernel_path="/opt/confidential-containers/share/kata-containers/vmlinuz-sev.container"
initrd_path="/opt/confidential-containers/share/kata-containers/kata-containers-initrd.img"
```
The kernel append line parameters are included in the SEV guest firmware measurement. A placeholder will be initially set, and the actual value will be retrieved later from the qemu command line:
```
append="PLACEHOLDER"
```
Use the `sev-snp-measure` utility to calculate the SEV guest firmware measurement using the binary variables previously set:
```
measurement=$(sev-snp-measure --mode=sev --output-format=base64 \
--ovmf="${ovmf_path}" \
--kernel="${kernel_path}" \
--initrd="${initrd_path}" \
--append="${append}" \
)
```
If the container image is not already present, pull it:
```
encrypted_image_url="ghcr.io/fitzthum/encrypted-image-tests:unencrypted"
docker pull "${encrypted_image_url}"
```
Retrieve the encryption key from docker image label:
```
enc_key=$(docker inspect ${encrypted_image_url} \
| jq -r '.[0].Config.Labels.enc_key')
```
Add the key, keyset and policy with measurement to the `simple-kbs` database:
```
mysql -u${KBS_DB_USER} -p${KBS_DB_PW} -h ${KBS_DB_HOST} -D ${KBS_DB} <<EOF
REPLACE INTO secrets VALUES (10, 'key_id1', '${enc_key}', 10);
REPLACE INTO keysets VALUES (10, 'KEYSET-1', '["key_id1"]', 10);
REPLACE INTO policy VALUES (10, '["${measurement}"]', '[]', 0, 0, '[]', now(), NULL, 1);
EOF
```
Using the same service yaml from the section on [Launch the Pod and Verify SEV Encryption](#launch-the-pod-and-verify-sev-encryption), launch the service:
```
kubectl apply -f encrypted-image-tests.yaml
```
Check for pod errors:
```
pod_name=$(kubectl get pod -o wide | grep encrypted-image-tests | awk '{print $1;}')
kubectl describe pod ${pod_name}
```
The pod will error out on the key retrieval request to the `simple-kbs` because the policy verification failed due to a mismatch in the SEV guest firmware measurement. This is the error message that should display:
```
Policy validation failed: fw digest not valid
```
The `PLACEHOLDER` value that was set for the kernel append line when the SEV guest firmware measurement was calculated does not match what was measured by the kata shim. The kernel append line parameters can be retrieved from the qemu command line using the following scripting commands, as long as kubernetes is still trying to launch the pod:
```
duration=$((SECONDS+30))
set append
while [ $SECONDS -lt $duration ]; do
qemu_process=$(ps aux | grep qemu | grep append || true)
if [ -n "${qemu_process}" ]; then
append=$(echo ${qemu_process} \
| sed "s|.*-append \(.*$\)|\1|g" \
| sed "s| -.*$||")
break
fi
sleep 1
done
echo "${append}"
```
The above check will only work if the `encrypted-image-tests` guest launch is the only consuming qemu process running.
Now, recalculate the SEV guest firmware measurement and store the `simple-kbs` policy in the database:
```
measurement=$(sev-snp-measure --mode=sev --output-format=base64 \
--ovmf="${ovmf_path}" \
--kernel="${kernel_path}" \
--initrd="${initrd_path}" \
--append="${append}" \
)
mysql -u${KBS_DB_USER} -p${KBS_DB_PW} -h ${KBS_DB_HOST} -D ${KBS_DB} <<EOF
REPLACE INTO secrets VALUES (10, 'key_id1', '${enc_key}', 10);
REPLACE INTO keysets VALUES (10, 'KEYSET-1', '["key_id1"]', 10);
REPLACE INTO policy VALUES (10, '["${measurement}"]', '[]', 0, 0, '[]', now(), NULL, 1);
EOF
```
The pod should now show a successful launch:
```
kubectl describe pod ${pod_name}
```
If the service is hung up, delete the pod and try to launch again:
```
# Delete
kubectl delete -f encrypted-image-tests.yaml
# Verify pod cleaned up
kubectl describe pod ${pod_name}
# Relaunch
kubectl apply -f encrypted-image-tests.yaml
```
Testing the SEV encrypted container launch can be completed by returning to the section on how to [Verify SEV Memory Encryption](#verify-sev-memory-encryption).

The CoCo operator environment has been setup and deployed!
### Platform Setup
While the operator deploys all the required binaries and artifacts and sets up runtime classes that use them,
certain platforms may require additional configuration to enable confidential computing. For example, the host
kernel and firmware might need to be configured.
See the [guides](./guides) for more information.
certain platforms may require additional configuration to enable confidential computing. For example, a specific
host kernel or firmware may be required. See the [guides](./guides/) for more information.
# Running a workload
## Using CoCo
## Creating a sample CoCo workload
Below is a brief summary and description of some of the CoCo use cases and features:
Once you've used the operator to install Confidential Containers, you can run a pod with CoCo by simply adding a runtime class.
First, we will use the `kata` runtime class which uses CoCo without hardware support.
Initially we will try this with an unencrypted container image.
- **Container Launch with Only Memory Encryption (No Attestation)** - Launch a container with memory encryption
- **Container Launch with Encrypted Image** - Launch an encrypted container by proving the workload is running
in a TEE in order to retrieve the decryption key
- **Container Launch with Image Signature Verification** - Launch a container and verify the authenticity and
integrity of an image by proving the workload is running in a TEE
- **Sealed secret** - Implement wrapped kubernetes secrets that are confidential to the workload owner and are
automatically decrypted by proving the workload is running in a TEE
- **Ephemeral Storage** - Temporary storage that is used during the lifecycle of the container but is cleared out
when a pod is restarted or finishes its task. At the moment, only ephemeral storage of the container itself is
supported and it has to be explicityly configured.
- **Authenticated Registries** - Create secure container registries that require authentication to access and manage container
images that ensures that only trusted images are deployed in the Confidential Container. The host must have access
to the registry credentials.
- **Secure Storage** - Mechanisms and technologies used to protect data at rest, ensuring that sensitive information
remains confidential and tamper-proof.
- **Peer Pods** - Enable the creation of VMs on any environment without requiring bare metal servers or nested
virtualization support. More information about this feature can be found [here](https://github.com/confidential-containers/cloud-api-adaptor/tree/main).
## Platforms
In our example we will be using the bitnami/nginx image as described in the following yaml:
```
apiVersion: v1
kind: Pod
metadata:
labels:
run: nginx
name: nginx
annotations:
io.containerd.cri.runtime-handler: kata
spec:
containers:
- image: bitnami/nginx:1.22.0
name: nginx
dnsPolicy: ClusterFirst
runtimeClassName: kata
```
With some TEEs, the CoCo use cases and/or configurations are implemented differently. Those are described in each corresponding
[guide](./guides) section. To get started using CoCo without TEE hardware, follow the CoCo-dev guide below:
Setting the runtimeClassName is usually the only change needed to the pod yaml, but some platforms
support additional annotations for configuring the enclave. See the [guides](./guides) for
more details.
With Confidential Containers, the workload container images are never downloaded on the host.
For verifying that the container image doesnt exist on the host you should log into the k8s node and ensure the following command returns an empty result:
```
root@cluster01-master-0:/home/ubuntu# crictl -r unix:///run/containerd/containerd.sock image ls | grep bitnami/nginx
```
You will run this command again after the container has started.
Create a pod YAML file as previously described (we named it `nginx.yaml`) .
Create the workload:
```
kubectl apply -f nginx.yaml
```
Output:
```
pod/nginx created
```
Ensure the pod was created successfully (in running state):
```
kubectl get pods
```
Output:
```
NAME READY STATUS RESTARTS AGE
nginx 1/1 Running 0 3m50s
```
Now go back to the k8s node and ensure that you still dont have any bitnami/nginx images on it:
```
root@cluster01-master-0:/home/ubuntu# crictl -r unix:///run/containerd/containerd.sock image ls | grep bitnami/nginx
```
## Encrypted and/or signed images with attestation
The previous example does not involve any attestation because the workload container isn't signed or encrypted
and the workload itself does not require any secrets.
This is not the case for most real workloads. It is recommended to use CoCo with signed and/or encrypted images.
The workload itself can also request secrets from the attestation agent in the guest.
Secrets are provisioned to the guest in conjunction with an attestation, which is based on hardware evidence.
The rest of this guide focuses on setting up more substantial encrypted/signed workloads using attestation
and confidential hardware.
CoCo has a modular attestation interface and there are a few options for attestation.
CoCo provides a generic Key Broker Service (KBS) that the rest of this guide will be focused on.
The SEV runtime class uses `simple-kbs`, which is described in the [SEV guide](./guides/sev.md).
There is also `eaa_kbc`/`verdictd` which is described [here](./guides/eaa_verdictd.md).
### Select Runtime Class
To use CoCo with confidential hardware, first switch to the appropriate runtime class.
TDX has two runtime classes, `kata-qemu-tdx` and `kata-clh-tdx`. One uses QEMU as VMM and TDVF as firmware. The other uses Cloud Hypervisor as VMM and TD-Shim as firmware.
For SEV(-ES) use the `kata-qemu-sev` runtime class and follow the [SEV guide](./guides/sev.md).
For `enclave-cc` follow the [enclave-cc guide](./guides/enclave-cc.md).
### Deploy and Configure tenant-side CoCo Key Broker System cluster
The following describes how to run and provision the generic KBS.
The KBS should be run in a trusted environment. The KBS is not just one service,
but a combination of several.
A tenant-side CoCo Key Broker System cluster includes:
- Key Broker Service (KBS): Brokering service for confidential resources.
- Attestation Service (AS): Verifier for remote attestation.
- Reference Value Provicer Service (RVPS): Provides reference values for AS.
- CoCo Keyprovider: Component to encrypt the images following ocicrypt spec.
To quick start the KBS cluster, a `docker compose` yaml is provided to launch.
```shell
# Clone KBS git repository
git clone https://github.com/confidential-containers/kbs.git
cd kbs/kbs
export KBS_DIR_PATH=$(pwd)
# Generate a user auth key pair
openssl genpkey -algorithm ed25519 > config/private.key
openssl pkey -in config/private.key -pubout -out config/public.pub
# Start KBS cluster
docker compose up -d
```
If configuration of KBS cluster is required, edit the following config files and restart the KBS cluster with `docker compose`:
- `$KBS_DIR_PATH/config/kbs-config.json`: configuration for Key Broker Service.
- `$KBS_DIR_PATH/config/as-config.json`: configuration for Attestation Service.
- `$KBS_DIR_PATH/config/sgx_default_qcnl.conf`: configuration for Intel TDX/SGX verification.
When KBS cluster is running, you can modify the policy file used by AS policy engine ([OPA](https://www.openpolicyagent.org/)) at any time:
- `$KBS_DIR_PATH/data/attestation-service/opa/policy.rego`: Policy file for evidence verification of AS, refer to [AS Policy Engine](https://github.com/confidential-containers/attestation-service#policy-engine) for more infomation.
### Encrypting an Image
[skopeo](https://github.com/containers/skopeo) is required to encrypt the container image.
Follow the [instructions](https://github.com/containers/skopeo/blob/main/install.md) to install `skopeo`.
Use `skopeo` to encrypt an image on the same node of the KBS cluster (use busybox:latest for example):
```shell
# edit ocicrypt.conf
tee > ocicrypt.conf <<EOF
{
"key-providers": {
"attestation-agent": {
"grpc": "127.0.0.1:50000"
}
}
}
EOF
# encrypt the image
OCICRYPT_KEYPROVIDER_CONFIG=ocicrypt.conf skopeo copy --insecure-policy --encryption-key provider:attestation-agent docker://library/busybox oci:busybox:encrypted
```
The image will be encrypted, and things happens in the KBS cluster background include:
- CoCo Keyprovider generates a random key and a key-id. Then encrypts the image using the key.
- CoCo Keyprovider registers the key with key-id into KBS.
Then push the image to registry:
```shell
skopeo copy oci:busybox:encrypted [SCHEME]://[REGISTRY_URL]:encrypted
```
Be sure to replace `[SCHEME]` with registry scheme type like `docker`, replace `[REGISTRY_URL]` with the desired registry URL like `docker.io/encrypt_test/busybox`.
### Signing an Image
[cosign](https://github.com/sigstore/cosign) is required to sign the container image. Follow the instructions here to install `cosign`:
[cosign installation](https://docs.sigstore.dev/cosign/system_config/installation/)
Generate a cosign key pair and register the public key to KBS storage:
```shell
cosign generate-key-pair
mkdir -p $KBS_DIR_PATH/data/kbs-storage/default/cosign-key && cp cosign.pub $KBS_DIR_PATH/data/kbs-storage/default/cosign-key/1
```
Sign the encrypted image with cosign private key:
```shell
cosign sign --key cosign.key [REGISTRY_URL]:encrypted
```
Be sure to replace `[REGISTRY_URL]` with the desired registry URL of the encrypted image generated in previous steps.
Then edit an image pulling validation policy file.
Here is a sample policy file `security-policy.json`:
```json
{
"default": [{"type": "reject"}],
"transports": {
"docker": {
"[REGISTRY_URL]": [
{
"type": "sigstoreSigned",
"keyPath": "kbs:///default/cosign-key/1"
}
]
}
}
}
```
Be sure to replace `[REGISTRY_URL]` with the desired registry URL of the encrypted image.
Register the image pulling validation policy file to KBS storage:
```shell
mkdir -p $KBS_DIR_PATH/data/kbs-storage/default/security-policy
cp security-policy.json $KBS_DIR_PATH/data/kbs-storage/default/security-policy/test
```
### Deploy encrypted image as a CoCo workload on CC HW
Here is a sample yaml for encrypted image deploying:
```shell
cat << EOT | tee encrypted-image-test-busybox.yaml
apiVersion: v1
kind: Pod
metadata:
labels:
run: encrypted-image-test-busybox
name: encrypted-image-test-busybox
annotations:
io.containerd.cri.runtime-handler: [RUNTIME_CLASS]
spec:
containers:
- image: [REGISTRY_URL]:encrypted
name: busybox
dnsPolicy: ClusterFirst
runtimeClassName: [RUNTIME_CLASS]
EOT
```
Be sure to replace `[REGISTRY_URL]` with the desired registry URL of the encrypted image generated in previous step, replace `[RUNTIME_CLASS]` with kata runtime class for CC HW.
Then configure `/opt/confidential-containers/share/defaults/kata-containers/configuration-<RUNTIME_CLASS_SUFFIX>.toml` to add `agent.aa_kbc_params=cc_kbc::<KBS_URI>` to kernel parameters. Here `RUNTIME_CLASS_SUFFIX` is something like `qemu-tdx`, `KBS_URI` is the address of Key Broker Service in KBS cluster like `http://123.123.123.123:8080`.
Deploy encrypted image as a workload:
```shell
kubectl apply -f encrypted-image-test-busybox.yaml
```
- [CoCo-dev](./guides/coco-dev.md)

# Confidential Containers Roadmap
When looking at the project's roadmap we distinguish between the short-term roadmap (2-4 months) vs.
the mid/long-term roadmap (4-12 months):
- The **short-term roadmap** is focused on achieving an end-to-end, easy to deploy confidential
containers solution using at least one HW encryption solution and integrated to k8s (with forked
versions if needed)
- The **mid/long-term solutions** focuses on maturing the components of the short-term solution
and adding a number of enhancements both to the solution and the project (such as CI,
interoperability with other projects etc.)
# Short-Term Roadmap
The short-term roadmap aims to achieve the following:
- MVP stack for running confidential containers
- Based on and compatible with Kata Containers 2
- Based on at least one confidential computing implementation (SEV, TDX, SE, etc)
- Integration with Kubernetes: kubectl apply -f confidential-pod.yaml
When looking at the project's roadmap we distinguish between the short-term roadmap (2-6 months) vs. the mid/long-term roadmap (6-18 months):
- The [short term roadmap](#short-term-roadmap) is focused on achieving an end-to-end, easy to deploy and stable confidential containers solution. We track this work on a number of github boards.
- The [mid and long term roadmap](#mid-and-long-term-roadmap) focuses on use case driven development.
The work is targeted to be completed by end of November 2021 and includes 3 milestones:
![September 2021](./images/RoadmapSept2021.jpg)
- **September 2021**
- Unencrypted image pulled inside the guest, kept in tmpfs
- Pod/Container runs from pulled image
- Agent API is restricted
- crictl only
![October 2021](./images/RoadmapOct2021.jpg)
- **October 2021**
- Encrypted image pulled inside the guest, kept in tmpfs
- Image is decrypted with a pre-provisioned key (No attestation)
![November 2021](./images/RoadmapNov2021.jpg)
- **November 2021**
- Image is optionally stored on an encrypted, ephemeral block device
- Image is decrypted with a key obtained from a key brokering service (KBS)
- Integration with kubelet
# Short Term Roadmap
The short-term roadmap is based on our github boards and delivered through our on-going releases
For additional details on each milestone see [Confidential Containers v0](https://docs.google.com/presentation/d/1SIqLogbauLf6lG53cIBPMOFadRT23aXuTGC8q-Ernfw/edit#slide=id.p).
- [Confidential containers github board](https://github.com/orgs/confidential-containers/projects/6/views/22)
- [Trustee github board](https://github.com/orgs/confidential-containers/projects/10/views/1)
Tasks are tracked on a weekly basis through a dedicated spreadsheet.
For more information see [Confidential Containers V0 Plan](https://docs.google.com/spreadsheets/d/1M_MijAutym4hMg8KtIye1jIDAUMUWsFCri9nq4dqGvA/edit#gid=0&fvid=1397558749).
# Mid and Long Term Roadmap
In CoCo use case driven development we identify the main functional requirements the community requires by focusing on key use cases.
# Mid-Term Roadmap
This helps the community deliver releases which address real use cases customers require and focusing on the right priorities. The use case driven development approach also includes developing the relevant CI/CDs to ensure end-to-end use cases the community delivers work over time.
Continue our journey using knowledge and support of Subject Matter Experts (SME's) in other
projects to form stronger opinions on what is needed from components which can be integrated to
deliver the confidential containers objectives.
We target the following use cases:
- Harden the code used for the demos
- Improve CI/CD pipeline
- Clarify the release process
- Establish processes and tools to support planning, prioritisation, and work in progress
- Simple process to get up and running regardless of underlying Trusted Execution Environment
technology
- Develop a small, simple, secure, lightweight and high performance OCI container image
management library [image-rs](https://github.com/confidential-containers/image-rs) for
confidential containers.
- Develop small, simple shim firmware ([td-shim](https://github.com/confidential-containers/td-shim))
in support of trusted execution environment for use with cloud native confidential containers.
- Document threat model and trust model, what are we protecting, how are we achieving it.
- Identify technical convergence points with other confidential computing projects both inside
and outside CNCF.
- Confidential Federated Learning
- Multi-party Computing (data clean room, confidential spaces etc)
- Trusted Pipeline (Supply Chain)
- Confidential RAG LLMs
# Longer-Term Roadmap
These use cases are outlined within [Confidential Computing Use Case Slides](https://docs.google.com/presentation/d/1YSybvMRku1eoFjAmign9DzKGRpKW4REPYpJCNT0sxmc) created by a dedicated working group.
Focused meetings will be set up to discuss architecture and the priority of longer-term objectives
in the process of being set up.
Each meeting will have an agreed focus with people sharing material/thoughts ahead of time.
Topics under consideration:
- CI/CD + repositories
- Community structure and expectations
- 2 on Mid-Term Architecture
- Attestation
- Images
- Runtimes
Proposed Topics to influence long-term direction/architecture:
- Baremetal / Peer Pod
- Composability of alternative technologies to deliver confidential containers
- Performance
- Identity / Service Mesh
- Reproducible builds/demos
- Edge Computing
- Reduce footprint of image pull
For additional details we recommend reviewing the working group's notes: [Confidential containers use cases driven development](https://docs.google.com/document/d/1LnGNeyUyPM61Iv4kBKFbfgmBr3RmxHYZ7Ev88obN0_E/edit?tab=t.0#heading=h.b0rnn2bw76n)
