-# Kata Containers CI
-
-> [!WARNING]
-> While this project's CI has several areas for improvement, it is constantly
-> evolving. This document attempts to describe its current state, but due to
-> ongoing changes, you may notice some outdated information here. Feel free to
-> modify/improve this document as you use the CI and notice anything odd. The
-> community appreciates it!
-
-## Introduction
-
-The Kata Containers CI relies on [GitHub Actions][gh-actions], where the actions
-themselves can be found in the `.github/workflows` directory, and they may call
-helper scripts, which are located under the `tests` directory, to actually
-perform the tasks required for each test case.
-
-## The different workflows
-
-There are a few different sets of workflows that are running as part of our CI,
-and here we're going to cover the ones that are less likely to get rotten.  With
-this said, it's fair to advise that if the reader finds something that got
-rotten, opening an issue to the project pointing to the problem is a nice way to
-help, and providing a fix for the issue is a very encouraging way to help.
-
-### Jobs that run automatically when a PR is raised
-
-These are a bunch of tests that will automatically run as soon as a PR is
-opened, they're mostly running on "cost free" runners, and they do some
-pre-checks to evaluate that your PR may be okay to start getting reviewed.
-
-Mind, though, that the community expects the contributors to, at least, build
-their code before submitting a PR, which the community sees as a very fair
-request.
-
-Without getting into the weeds with details on this, those jobs are the ones
-responsible for ensuring that:
-
-- The commit message is in the expected format
-- There's no missing Developer's Certificate of Origin
-- Static checks are passing
-
-### Jobs that require a maintainer's approval to run
-
-These are the required tests, and our so-called "CI".  These require a
-maintainer's approval to run as parts of those jobs will be running on "paid
-runners", which are currently using Azure infrastructure.
-
-Once a maintainer of the project gives "the green light" (currently by adding an
-`ok-to-test` label to the PR, soon to be changed to commenting "/test" as part
-of a PR review), the following tests will be executed:
-
-- Build all the components (runs on free cost runners, or bare-metal depending on the architecture)
-- Create a tarball with all the components (runs on free cost runners, or bare-metal depending on the architecture)
-- Create a kata-deploy payload with the tarball generated in the previous step (runs on free costs runner, or bare-metal depending on the architecture)
-- Run the following tests:
-  - Tests depending on the generated tarball
-    - Metrics (runs on bare-metal)
-    - `docker` (runs on Azure small instances)
-    - `nerdctl` (runs on Azure small instances)
-    - `kata-monitor` (runs on Azure small instances)
-    - `cri-containerd` (runs on Azure small instances)
-    - `nydus` (runs on Azure small instances)
-    - `vfio` (runs on Azure normal instances)
-  - Tests depending on the generated kata-deploy payload
-    - kata-deploy (runs on Azure small instances)
-      - Tests are performed using different "Kubernetes flavors", such as k0s, k3s, rke2, and Azure Kubernetes Service (AKS).
-    - Kubernetes (runs in Azure small and medium instances depending on what's required by each test, and on TEE bare-metal machines)
-      - Tests are performed with different runtime engines, such as CRI-O and containerd.
-      - Tests are performed with different snapshotters for containerd, namely OverlayFS and devmapper.
-      - Tests are performed with all the supported hypervisors, which are Cloud Hypervisor, Dragonball, Firecracker, and QEMU.
-
-For all the tests relying on Azure instances, real money is being spent, so the
-community asks for the maintainers to be mindful about those, and avoid abusing
-them to merely debug issues.
-
-## The different runners
-
-In the previous section we've mentioned using different runners, now in this section we'll go through each type of runner used.
-
-- Cost free runners:  Those are the runners provided by GIthub itself, and
-  those are fairly small machines with no virtualization capabilities enabled - 
-- Azure small instances: Those are runners which have virtualization
-  capabilities enabled, 2 CPUs, and 8GB of RAM.  These runners have a "-smaller"
-  suffix to their name. 
-- Azure normal instances: Those are runners which have virtualization
-  capabilities enabled, 4 CPUs, and 16GB of RAM.  These runners are usually
-  `garm` ones with no "-smaller" suffix.
-- Bare-metal runners: Those are runners provided by community contributors,
-  and they may vary in architecture, size and virtualization capabilities.
-  Builder runners don't actually require any virtualization capabilities, while
-  runners which will be actually performing the tests must have virtualization
-  capabilities and a reasonable amount for CPU and RAM available (at least
-  matching the Azure normal instances).
-  
-## Adding new tests
-
-Before someone decides to add a new test, we strongly recommend them to go
-through [GitHub Actions Documentation][gh-actions],
-which will provide you a very sensible background on how to read and understand
-current tests we have, and also become familiar with how to write a new test.
-
-On the Kata Containers land, there are basically two sets of tests: "standalone"
-and "part of something bigger".
-
-The "standalone" tests, for example the commit message check, won't be covered
-here as they're better covered by the GitHub Actions documentation pasted above.
-
-The "part of something bigger" is the more complicated one and not so
-straightforward to add, so we'll be focusing our efforts on describing the
-addition of those.
-
-> [!NOTE]
-> TODO: Currently, this document refers to "tests" when it actually means the
-> jobs (or workflows) of GitHub. In an ideal world, except in some specific cases,
-> new tests should be added without the need to add new workflows. In the
-> not-too-distant future (hopefully), we will improve the workflows to support
-> this.
-
-### Adding a new test that's "part of something bigger"
-
-The first important thing here is to align expectations, and we must say that
-the community strongly prefers receiving tests that already come with:
-
-- Instructions how to run them
-- A proven run where it's passing
-
-There are several ways to achieve those two requirements, and an example of that
-can be seen in PR #8115.
-
-With the expectations aligned, adding a test consists in:
-
-- Adding a new yaml file for your test, and ensure it's called from the
-  "bigger" yaml. See the [Kata Monitor test example][monitor-ex01].
-
-- Adding the helper scripts needed for your test to run. Again, use the [Kata Monitor script as example][monitor-ex02].
-
-Following those examples, the community advice during the review, and even
-asking the community directly on Slack are the best ways to get your test
-accepted.
-
-## Running tests
-
-### Running the tests as part of the CI
-
-If you're a maintainer of the project, you'll be able to kick in the tests by
-yourself.  With the current approach, you just need to add the `ok-to-test`
-label and the tests will automatically start.  We're moving, though, to use a
-`/test` command as part of a GitHub review comment, which will simplify this
-process.
-
-If you're not a maintainer, please, send a message on Slack or wait till one of
-the maintainers reviews your PR.  Maintainers will then kick in the tests on
-your behalf.
-
-In case a test fails and there's the suspicion it happens due to flakiness in
-the test itself, please, create an issue for us, and then re-run (or asks
-maintainers to re-run) the tests following these steps:
-
-- Locate which tests is failing
-- Click in "details"
-- In the top right corner, click in "Re-run jobs"
-- And then in "Re-run failed jobs"
-- And finally click in the green "Re-run jobs" button
-
-> [!NOTE]
-> TODO: We need figures here
-
-### Running the tests locally
-
-In this section, aligning expectations is also something very important, as one
-will not be able to run the tests exactly in the same way the tests are running
-in the CI, as one most likely won't have access to an Azure subscription.
-However, we're trying our best here to provide you with instructions on how to
-run the tests in an environment that's "close enough" and will help you to debug
-issues you find with the current tests, or even provide a proof-of-concept to
-the new test you're trying to add.
-
-The basic steps, which we will cover in details down below are:
-
- 1. Create a VM matching the configuration of the target runner
- 2. Generate the artifacts you'll need for the test, or download them from a
-    current failed run
- 3. Follow the steps provided in the action itself to run the tests.
-
-Although the general overview looks easy, we know that some tricks need to be
-shared, and we'll go through the general process of debugging one non-Kubernetes
-and one Kubernetes specific test for educational purposes.
-
-One important thing to note is that "Create a VM" can be done in innumerable
-different ways, using the tools of your choice.  For the sake of simplicity on
-this guide, we'll be using `kcli`, which we strongly recommend in case you're a
-non-experienced user, and happen to be developing on a Linux box.
-
-For both non-Kubernetes and Kubernetes cases, we'll be using PR #8070 as an
-example, which at the time this document is being written serves us very well
-the purpose, as you can see that we have `nerdctl` and Kubernetes tests failing.
-
-## Debugging tests
-
-### Debugging a non Kubernetes test
-
-As shown above, the `nerdctl` test is failing.
-
-As a developer you can go ahead to the details of the job, and expand the job
-that's failing in order to gather more information.
-
-But when that doesn't help, we need to set up our own environment to debug
-what's going on.
-
-Taking a look at the `nerdctl` test, which is located here, you can easily see
-that it runs-on a `garm-ubuntu-2304-smaller` virtual machine.
-
-The important parts to understand are `ubuntu-2304`, which is the OS where the
-test is running on; and "smaller", which means we're running it on a machine
-with 2 CPUs and 8GB of RAM.
-
-With this information, we can go ahead and create a similar VM locally using `kcli`.
-
-```bash
-$ sudo kcli create vm -i ubuntu2304 -P disks=[60] -P numcpus=2 -P memory=8192 -P cpumodel=host-passthrough debug-nerdctl-pr8070
-```
-
-In order to run the tests, you'll need the "kata-tarball" artifacts, which you
-can build your own using "make kata-tarball" (see below), or simply get them
-from the PR where the tests failed.  To download them, click on the "Summary"
-button that's on the top left corner, and then scroll down till you see the
-artifacts, as shown below.
-
-Unfortunately GitHub doesn't give us a link that we can download those from
-inside the VM, but we can download them on our local box, and then `scp` the
-tarball to the newly created VM that will be used for debugging purposes.
-
-> [!NOTE]
-> Those artifacts are only available (for 15 days) when all jobs are finished.
-
-Once you have the `kata-static.tar.xz` in your VM, you can login to the VM with
-`kcli ssh debug-nerdctl-pr8070`, go ahead and then clone your development branch
-
-```bash
-$ git clone --branch feat_add-fc-runtime-rs https://github.com/nubificus/kata-containers
-```
-
-Add the upstream as a remote, set up your git, and rebase your branch atop of the upstream main one
-
-```bash
-$ git remote add upstream https://github.com/kata-containers/kata-containers
-$ git remote update
-$ git config --global user.email "you@example.com"
-$ git config --global user.name "Your Name"
-$ git rebase upstream/main 
-```
-
-Now copy the `kata-static.tar.xz` into your `kata-containers/kata-artifacts` directory
-
-```bash
-$ mkdir kata-artifacts
-$ cp ../kata-static.tar.xz kata-artifacts/
-```
-
-> [!NOTE]
-> If you downloaded the .zip from GitHub you need to uncompress first to see `kata-static.tar.xz`
-
-And finally run the tests following what's in the yaml file for the test you're
-debugging. 
-
-In our case, the `run-nerdctl-tests-on-garm.yaml`.
-
-When looking at the file you'll notice that some environment variables are set,
-such as `KATA_HYPERVISOR`, and should be aware that, for this particular example,
-the important steps to follow are:
-
-Install the dependencies
-Install kata
-Run the tests
-
-Let's now run the steps mentioned above exporting the expected environment variables
-
-```bash
-$ export KATA_HYPERVISOR=dragonball
-$ bash ./tests/integration/nerdctl/gha-run.sh install-dependencies
-$ bash ./tests/integration/nerdctl/gha-run.sh install-kata
-$ bash tests/integration/nerdctl/gha-run.sh run
-```
-
-And with this you should've been able to reproduce exactly the same issue found
-in the CI, and from now on you can build your own code, use your own binaries,
-and have fun debugging and hacking! 
-
-### Debugging a Kubernetes test
-
-Steps for debugging the Kubernetes tests are very similar to the ones for
-debugging non-Kubernetes tests, with the caveat that what you'll need, this
-time, is not the `kata-static.tar.xz` tarball, but rather a payload to be used
-with kata-deploy.
-
-In order to generate your own kata-deploy image you can generate your own
-`kata-static.tar.xz` and then take advantage of the following script.  Be aware
-that the image generated and uploaded must be accessible by the VM where you'll
-be performing your tests.
-
-In case you want to take advantage of the payload that was already generated
-when you faced the CI failure, which is considerably easier, take a look at the
-failed job, then click in "Deploy Kata" and expand the "Final kata-deploy.yaml
-that is used in the test" section.  From there you can see exactly what you'll
-have to use when deploying kata-deploy in your local cluster.
-

-## Adding new runners
-
-Any admin of the project is able to add or remove GitHub runners, and those are
-the folks you should rely on.
-
-If you need a new runner added, please, tag @ac in the Kata Containers slack,
-and someone from that group will be able to help you.
-
-If you're part of that group and you're looking for information on how to help
-someone, this is simple, and must be done in private. Basically what you have to
-do is:
-
-- Go to the kata-containers/kata-containers repo
-- Click on the Settings button, located in the top right corner
-- On the left panel, under "Code and automation", click on "Actions"
-- Click on "Runners"
-
-If you want to add a new self-hosted runner:
-
-- In the top right corner there's a green button called "New self-hosted runner"
-
-If you want to remove a current self-hosted runner:
-
-- For each runner there's a "..." menu, where you can just click and the
-  "Remove runner" option will show up
-  
-## Known limitations
-
-As the GitHub actions are structured right now we cannot: Test the addition of a
-GitHub action that's not triggered by a pull_request event as part of the PR.

-# Using a debugger with the runtime
-
-Setting up a debugger for the runtime is pretty complex: the shim is a server
-process that is run by the runtime manager (containerd/CRI-O), and controlled by
-sending gRPC requests to it.
-Starting the shim with a debugger then just gives you a process that waits for
-commands on its socket, and if the runtime manager doesn't start it, it won't
-send request to it.
-
-A first method is to attach a debugger to the process that was started by the
-runtime manager.
-If the issue you're trying to debug is not located at container creation, this
-is probably the easiest method.
-
-The other method involves a script that is placed in between the runtime manager
-and the actual shim binary. This allows to start the shim with a debugger, and
-wait for a client debugger connection before execution, allowing debugging of the
-kata runtime from the very beginning.
-
-## Prerequisite
-
-At the time of writing, a debugger was used only with the go shim, but a similar
-process should be doable with runtime-rs. This documentation will be enhanced
-with rust-specific instructions later on.
-
-In order to debug the go runtime, you need to use the [Delve debugger](https://github.com/go-delve/delve).
-
-You will also need to build the shim binary with debug flags to make sure symbols
-are available to the debugger.
-Typically, the flags should be: `-gcflags=all=-N -l`
-
-## Attach to the running process
-
-To attach the debugger to the running process, all you need is to let the container
-start as usual, then use the following command with `dlv`:
-
-`$ dlv attach [pid of your kata shim]`
-
-If you need to use your debugger remotely, you can use the following on your target
-machine:
-
-`$ dlv attach [pid of your kata shim] --headless --listen=[IP:port]`
-
-then from your client computer:
-
-`$ dlv connect [IP:port]`
-
-## Make CRI-O/containerd start the shim with the debugger
-
-You can use the [this script](../tools/containerd-shim-katadbg-v2) to make the
-shim binary executed through a debugger, and make the debugger wait for a client
-connection before running the shim.
-This allows starting your container, connecting your debugger, and controlling the
-shim execution from the beginning.
-
-### Adapt the script to your setup
-
-You need to edit the script itself to give it the actual binary
-to execute.
-Locate the following line in the script, and set the path accordingly.
-
-```bash
-SHIM_BINARY=
-```
-
-You may also need to edit the `PATH` variable set within the script,
-to make sure that the `dlv` binary is accessible.
-
-### Configure your runtime manager to use the script
-
-Using either containerd or CRI-O, you will need to have a runtime class that
-uses the script in place of the actual runtime binary.
-To do that, we will create a separate runtime class dedicated to debugging.
-
-- **For containerd**:
-Make sure that the `containerd-shim-katadbg-v2` script is available to containerd
-(putting it in the same folder as your regular kata shim typically).
-Then edit the containerd configuration, and add the following runtime configuration,.
-
-```toml
-[plugins]
-  [plugins."io.containerd.grpc.v1.cri"]
-    [plugins."io.containerd.grpc.v1.cri".containerd]
-      [plugins."io.containerd.grpc.v1.cri".containerd.runtimes]
-        [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.katadbg]
-          runtime_type = "io.containerd.katadbg.v2"
-```
-
-- **For CRI-O**:
-Copy your existing kata runtime configuration from `/etc/crio/crio.conf.d/`, and
-make a new one with the name `katadbg`, and the runtime_path set to the location
-of the script.
-
-E.g:
-
-```toml
-[crio.runtime.runtimes.katadbg]
-  runtime_path = "/usr/local/bin/containerd-shim-katadbg-v2"
-  runtime_root = "/run/vc"
-  runtime_type = "vm"
-  privileged_without_host_devices = true
-  runtime_config_path = "/usr/share/defaults/kata-containers/configuration.toml"
- ```
-
-NOTE: for CRI-O, the name of the runtime class doesn't need to match the name of the
-script. But for consistency, we're using `katadbg` here too.
-
-### Start your container and connect to the debugger
-
-Once the above configuration is in place, you can start your container, using
-your `katadbg` runtime class.
-
-E.g: `$ crictl runp --runtime=katadbg sandbox.json`
-
-The command will hang, and you can see that a `dlv` process is started
-
-```
-$ ps aux | grep dlv
-root        9137  1.4  6.8 6231104 273980 pts/10 Sl   15:04   0:02 dlv exec /go/src/github.com/kata-containers/kata-containers/src/runtime/__debug_bin --headless --listen=:12345 --accept-multiclient -r stdout:/tmp/shim_output_oMC6Jo -r stderr:/tmp/shim_output_oMC6Jo -- -namespace default -address  -publish-binary /usr/local/bin/crio -id 0bc23d2208d4ff8c407a80cd5635610e772cae36c73d512824490ef671be9293 -debug start
-```
-
-Then you can use the `dlv` debugger to connect to it:
-
-```
-$ dlv connect localhost:12345
-Type 'help' for list of commands.
-(dlv)
-```
-
-Before doing anything else, you need to to enable `follow-exec` mode in delve.
-This is because the first thing that the shim will do is to daemonize itself,
-i.e: start itself as a subprocess, and exit. So you really want the debugger
-to attach to the child process.
-
-```
-(dlv) target follow-exec -on .*/__debug_bin
-```
-
-Note that we are providing a regular expression to filter the name of the binary.
-This is to make sure that the debugger attaches to the runtime shim, and not
-to other subprocesses (hypervisor typically).
-
-To ease this process, we recommand the use of an init file containing the above
-command.
-
-```
-$ cat dlv.ini
-target follow-exec -on .*/__debug_bin
-$ dlv connect localhost:12345 --init=dlv.ini
-Type 'help' for list of commands.
-(dlv)
-```
-
-Once this is done, you can set breakpoints, and use the `continue` keyword to
-start the execution of the shim.
-
-You can also use a different client, like VSCode, to connect to it.
-A typical `launch.json` configuration for VSCode would look like:
-
-```yaml
-[...]
-{
-    "name": "Connect to the debugger",
-    "type": "go",
-    "request": "attach",
-    "mode": "remote",
-    "port": 12345,
-    "host": "127.0.0.1",
-}
-[...]
-```
-
-NOTE: VSCode's go extension doesn't seem to support the `follow-exec` mode from
-Delve. So if you want to use VScode, you'll still need to use a commandline
-`dlv` client to set the `follow-exec` flag.
-
-## Caveats
-
-Debugging takes time, and there are a lot of timeouts going on in a Kubernetes
-environments. It is very possible that while you're debugging, some processes
-will timeout and cancel the container execution, possibly breaking your debugging
-session.
-
-You can mitigate that by increasing the timeouts in the different components
-involved in your environment.

 ## Release Process
 
-### Bump the `VERSION` file
 
-When the `kata-containers/kata-containers` repository is ready for a new release,
-first create a PR to set the release in the `VERSION` file and have it merged.
+### Bump all Kata repositories
 
-### Check GitHub Actions
+  Bump the repositories using a script in the Kata packaging repo, where:
+  - `BRANCH=<the-branch-you-want-to-bump>`
+  - `NEW_VERSION=<the-new-kata-version>`
+  ```
+  $ cd ${GOPATH}/src/github.com/kata-containers/kata-containers/tools/packaging/release
+  $ export NEW_VERSION=<the-new-kata-version>
+  $ export BRANCH=<the-branch-you-want-to-bump>
+  $ ./update-repository-version.sh -p "$NEW_VERSION" "$BRANCH"
+  ```
 
-We make use of [GitHub actions](https://github.com/features/actions) in the
-[release](https://github.com/kata-containers/kata-containers/actions/workflows/release.yaml)
-file from the `kata-containers/kata-containers` repository to build and upload
-release artifacts.
+### Point tests repository to stable branch
 
-The action is manually triggered and is responsible for generating a new
-release (including a new tag), pushing those to the
-`kata-containers/kata-containers` repository. The new release is initially
-created as a draft. It is promoted to an official release when the whole
-workflow has completed successfully.
+  If you create a new stable branch, i.e. if your release changes a major or minor version number (not a patch release), then
+  you should modify the `tests` repository to point to that newly created stable branch and not the `main` branch.
+  The objective is that changes in the CI on the main branch will not impact the stable branch.
 
-Check the [actions status
-page](https://github.com/kata-containers/kata-containers/actions) to verify all
-steps in the actions workflow have completed successfully. On success, a static
-tarball containing Kata release artifacts will be uploaded to the [Release
-page](https://github.com/kata-containers/kata-containers/releases).
+  In the test directory, change references the main branch in:
+  * `README.md`
+  * `versions.yaml`
+  * `cmd/github-labels/labels.yaml.in`
+  * `cmd/pmemctl/pmemctl.sh`
+  * `.ci/lib.sh`
+  * `.ci/static-checks.sh`
 
-If the workflow fails because of some external environmental causes, e.g. network
-timeout, simply re-run the failed jobs until they eventually succeed.
+  See the commits in [the corresponding PR for stable-2.1](https://github.com/kata-containers/tests/pull/3504) for an example of the changes.
 
-If for some reason you need to cancel the workflow or re-run it entirely, go first
-to the [Release page](https://github.com/kata-containers/kata-containers/releases) and
-delete the draft release from the previous run.
 
-### Improve the release notes
+### Merge all bump version Pull requests
 
-Release notes are auto-generated by the GitHub CLI tool used as part of our
-release workflow.  However, some manual tweaking may still be necessary in
-order to highlight the most important features and bug fixes in a specific
-release.
+  - The above step will create a GitHub pull request in the Kata projects. Trigger the CI using `/test` command on each bump Pull request.
+  - Trigger the `test-kata-deploy` workflow which is under the `Actions` tab on the repository GitHub page (make sure to select the correct branch and validate it passes).
+  - Check any failures and fix if needed.
+  - Work with the Kata approvers to verify that the CI works and the pull requests are merged.
 
-With this in mind, please, poke @channel on #kata-dev and people who worked on
-the release will be able to contribute to that.
+### Tag all Kata repositories
+
+  Once all the pull requests to bump versions in all Kata repositories are merged,
+  tag all the repositories as shown below.
+  ```
+  $ cd ${GOPATH}/src/github.com/kata-containers/kata-containers/tools/packaging/release
+  $ git checkout  <kata-branch-to-release>
+  $ git pull
+  $ ./tag_repos.sh -p -b "$BRANCH" tag
+  ```
+
+### Check Git-hub Actions
+
+  We make use of [GitHub actions](https://github.com/features/actions) in this [file](../.github/workflows/release.yaml) in the `kata-containers/kata-containers` repository to build and upload release artifacts. This action is auto triggered with the above step when a new tag is pushed to the `kata-containers/kata-containers` repository.
+
+  Check the [actions status page](https://github.com/kata-containers/kata-containers/actions) to verify all steps in the actions workflow have completed successfully. On success, a static tarball containing Kata release artifacts will be uploaded to the [Release page](https://github.com/kata-containers/kata-containers/releases).
+
+### Create release notes
+
+  We have a script in place in the packaging repository to create release notes that include a short-log of the commits across Kata components.
+
+  Run the script as shown below:
+
+  ```
+  $ cd ${GOPATH}/src/github.com/kata-containers/kata-containers/tools/packaging/release
+  # Note: OLD_VERSION is where the script should start to get changes.
+  $ ./release-notes.sh ${OLD_VERSION} ${NEW_VERSION} > notes.md
+  # Edit the `notes.md` file to review and make any changes to the release notes.
+  # Add the release notes in the project's GitHub.
+  $ hub release edit -F notes.md "${NEW_VERSION}"
+  ```
 
 ### Announce the release

+## Introduction 
+
+This document provides details about Kata Containers releases.
+
+## Versioning
+
+The Kata Containers project uses [semantic versioning](http://semver.org/) for all releases. 
+Semantic versions are comprised of three fields in the form:
+
+```
+MAJOR.MINOR.PATCH
+```
+
+For examples: `1.0.0`, `1.0.0-rc.5`, and `99.123.77+foo.bar.baz.5`.
+
+Semantic versioning is used since the version number is able to convey clear 
+information about how a new version relates to the previous version. 
+For example, semantic versioning can also provide assurances to allow users to know 
+when they must upgrade compared with when they might want to upgrade:
+
+- When `PATCH` increases, the new release contains important **security fixes**
+  and an upgrade is recommended.
+
+  The patch field can contain extra details after the number. 
+Dashes denote pre-release versions. `1.0.0-rc.5` in the example denotes the fifth release
+ candidate for release `1.0.0`. Plus signs denote other details. In our example, `+foo.bar.baz.5` 
+provides additional information regarding release `99.123.77` in the previous example.
+
+- When `MINOR` increases, the new release adds **new features** but *without
+  changing the existing behavior*.
+
+- When `MAJOR` increases, the new release adds **new features, bug fixes, or
+  both** and which **changes the behavior from the previous release** (incompatible with previous releases).
+
+  A major release will also likely require a change of the container manager version used, 
+for example Containerd or CRI-O. Please refer to the release notes for further details.
+
+## Release Strategy
+
+Any new features added since the last release will be available in the next minor
+release. These will include bug fixes as well. To facilitate a stable user environment, 
+Kata provides stable branch-based releases and a main branch release.
+
+## Stable branch patch criteria
+
+No new features should be introduced to stable branches.  This is intended to limit risk to users,
+providing only bug and security fixes.
+
+## Branch Management
+Kata Containers will maintain **one** stable release branch, in addition to the main branch, for
+each active major release.
+Once a new MAJOR or MINOR release is created from main, a new stable branch is created for
+the prior MAJOR or MINOR release and the previous stable branch is no longer maintained. End of
+maintenance for a branch is announced on the Kata Containers mailing list.  Users can determine
+the version currently installed by running `kata-runtime kata-env`. It is recommended to use the
+latest stable branch available.
+
+A couple of examples follow to help clarify this process.
+
+### New bug fix introduced
+
+A bug fix is submitted against the runtime which does not introduce new inter-component dependencies.
+This fix is applied to both the main and stable branches, and there is no need to create a new
+stable branch.
+
+| Branch | Original version | New version |
+|--|--|--|
+| `main` | `2.3.0-rc0` | `2.3.0-rc1` |
+| `stable-2.2` | `2.2.0` | `2.2.1` |
+| `stable-2.1` | (unmaintained) | (unmaintained) |
+
+
+### New release made feature or change adding new inter-component dependency
+
+A new feature is introduced, which adds a new inter-component dependency. In this case a new stable
+branch is created (stable-2.3) starting from main and the previous stable branch (stable-2.2)
+is dropped from maintenance.
+
+
+| Branch | Original version | New version |
+|--|--|--|
+| `main` | `2.3.0-rc1` | `2.3.0` |
+| `stable-2.3` | N/A| `2.3.0` |
+| `stable-2.2` | `2.2.1` | (unmaintained) |
+| `stable-2.1` | (unmaintained) | (unmaintained) |
+
+Note, the stable-2.2 branch will still exist with tag 2.2.1, but under current plans it is
+not maintained further. The next tag applied to main will be 2.4.0-alpha0. We would then
+create a couple of alpha releases gathering features targeted for that particular release (in
+this case 2.4.0), followed by a release candidate. The release candidate marks a feature freeze.
+A new stable branch is created for the release candidate. Only bug fixes and any security issues
+are added to the branch going forward until release 2.4.0 is made.
+   
+## Backporting Process 
+
+Development that occurs against the main branch and applicable code commits should also be submitted
+against the stable branches. Some guidelines for this process follow::
+  1. Only bug and security fixes which do not introduce inter-component dependencies are
+ candidates for stable branches. These PRs should be marked with "bug" in GitHub.
+  2. Once a PR is created against main which meets requirement of (1), a comparable one
+ should also be submitted against the stable branches. It is the responsibility of the submitter
+ to apply their pull request against stable, and it is the responsibility of the
+ reviewers to help identify stable-candidate pull requests.
+ 
+## Continuous Integration Testing
+
+The test repository is forked to create stable branches from main. Full CI
+runs on each stable and main PR using its respective tests repository branch.
+
+### An alternative method for CI testing:
+
+Ideally, the continuous integration infrastructure will run the same test suite on both main
+and the stable branches.  When tests are modified or new feature tests are introduced, explicit
+logic should exist within the testing CI to make sure only applicable tests are executed against
+stable and main. While this is not in place currently, it should be considered in the long term.
+
+## Release Management
+
+### Patch releases
+
+Releases are made every four weeks, which include a GitHub release as
+well as binary packages. These patch releases are made for both stable branches, and a "release candidate"
+for the next `MAJOR` or `MINOR` is created from main. If there are no changes across all the repositories, no
+release is created and an announcement is made on the developer mailing list to highlight this.
+If a release is being made, each repository is tagged for this release, regardless
+of whether changes are introduced. The release schedule can be seen on the
+[release rotation wiki page](https://github.com/kata-containers/community/wiki/Release-Team-Rota).
+
+If there is urgent need for a fix, a patch release will be made outside of the planned schedule.
+
+The process followed for making a release can be found at [Release Process](Release-Process.md).
+
+## Minor releases
+
+###  Frequency
+Minor releases are less frequent in order to provide a more stable baseline for users. They are currently
+running on a sixteen weeks cadence. The release schedule can be seen on the
+[release rotation wiki page](https://github.com/kata-containers/community/wiki/Release-Team-Rota).
+
+### Compatibility
+Kata guarantees compatibility between components that are within one minor release of each other. 
+ 
+This is critical for dependencies which cross between host (shimv2 runtime) and
+the guest (hypervisor, rootfs and agent).  For example, consider a cluster with a long-running
+deployment, workload-never-dies, all on Kata version 2.1.3 components. If the operator updates
+the Kata components to the next new minor release (i.e. 2.2.0), we need to guarantee that the 2.2.0
+shimv2 runtime still communicates with 2.1.3 agent within workload-never-dies.
+
+Handling live-update is out of the scope of this document. See this [`kata-runtime` issue](https://github.com/kata-containers/runtime/issues/492) for details.

-# Kata Containers support for `Hooks`
-
-## Introduction
-
-During container's lifecycle, different Hooks can be executed to do custom actions. In Kata Containers, we support two types of Hooks, `OCI Hooks` and `Kata Hooks`.
-
-### OCI Hooks
-
-The OCI Spec stipulates six hooks that can be executed at different time points and namespaces, including `Prestart Hooks`, `CreateRuntime Hooks`, `CreateContainer Hooks`, `StartContainer Hooks`, `Poststart Hooks` and `Poststop Hooks`. We support these types of Hooks as compatible as possible in Kata Containers.
-
-The path and arguments of these hooks will be passed to Kata for execution via `bundle/config.json`. For example:
-```
-...
-"hooks": {
-  "prestart": [
-    {
-      "path": "/usr/bin/prestart-hook",
-      "args": ["prestart-hook", "arg1", "arg2"],
-      "env":  [ "key1=value1"]
-    }
-  ],
-  "createRuntime": [
-    {
-      "path": "/usr/bin/createRuntime-hook",
-      "args": ["createRuntime-hook", "arg1", "arg2"],
-      "env":  [ "key1=value1"]
-    }
-  ]
-}
-...
-```
-
-### Kata Hooks
-
-In Kata, we support another three kinds of hooks executed in guest VM, including `Guest Prestart Hook`, `Guest Poststart Hook`, `Guest Poststop Hook`.
-
-The executable files for Kata Hooks must be packaged in the *guest rootfs*. The file path to those guest hooks should be specified in the configuration file, and guest hooks must be stored in a subdirectory of `guest_hook_path` according to their hook type. For example:
-
-+ In configuration file:
-```
-guest_hook_path="/usr/share/hooks"
-```
-+ In guest rootfs, prestart-hook is stored in `/usr/share/hooks/prestart/prestart-hook`.
-
-## Execution
-The table below summarized when and where those different hooks will be executed in Kata Containers:
-
-| Hook Name | Hook Type | Hook Path | Exec Place | Exec Time |
-|---|---|---|---|---|
-| `Prestart(deprecated)` | OCI hook | host runtime namespace | host runtime namespace | After VM is started, before container is created. |
-| `CreateRuntime` | OCI hook | host runtime namespace | host runtime namespace | After VM is started, before container is created, after `Prestart` hooks. |
-| `CreateContainer` | OCI hook | host runtime namespace | host vmm namespace* | After VM is started, before container is created, after `CreateRuntime` hooks. |
-| `StartContainer` | OCI hook | guest container namespace | guest container namespace | After container is created, before container is started. |
-| `Poststart` | OCI hook | host runtime namespace | host runtime namespace | After container is started, before start operation returns. |
-| `Poststop` | OCI hook | host runtime namespace | host runtime namespace | After container is deleted, before delete operation returns. |
-| `Guest Prestart` | Kata hook | guest agent namespace | guest agent namespace | During start operation, before container command is executed. |
-| `Guest Poststart` | Kata hook | guest agent namespace | guest agent namespace | During start operation, after container command is executed, before start operation returns. |
-| `Guest Poststop` | Kata hook | guest agent namespace | guest agent namespace | During delete operation, after container is deleted, before delete operation returns. |
-
-+ `Hook Path` specifies where hook's path be resolved.
-+ `Exec Place` specifies in which namespace those hooks can be executed.
-  + For `CreateContainer` Hooks, OCI requires to run them inside the container namespace while the hook executable path is in the host runtime, which is a non-starter for VM-based containers. So we design to keep them running in the *host vmm namespace.* 
-+ `Exec Time` specifies at which time point those hooks can be executed.

-# Kata Containers Guest Image Management Design
-
-To safeguard the integrity of container images and prevent tampering from the host side, we propose guest image management. This method, employed for Confidential Containers, ensures container images remain unaltered and secure.
-
-## Introduction to remote snapshot
-Containerd 1.7 introduced `remote snapshotter` feature which is the foundation for pulling images in the guest for Confidential Containers.
-
-While it's beyond the scope of this document to fully explain how the container rootfs is created to the point it can be executed,  a fundamental grasp of the snapshot concept is essential. Putting it in a simple way, containerd fetches the image layers from an OCI registry into its local content storage. However, they cannot be mounted as is (e.g. the layer can be tar+gzip compressed) as well as they should be immutable so the content can be shared among containers. Thus containerd leverages snapshots of those layers to build the container's rootfs. 
-
-The role of `remote snapshotter` is to reuse snapshots that are stored in a remotely shared place, thus enabling containerd to prepare the container’s rootfs in a manner similar to that of a local `snapshotter`. The key behavior that makes this the building block of Kata's guest image management for Confidential Containers is that containerd will not pull the image layers from registry, instead it assumes that `remote snapshotter` and/or an external entity will perform that operation on his behalf.
-
-Maybe the simplest example of `remote snapshotter` in Confidential Containers is the pulling of images in the guest VM. Once ensuring the VM is part of a Trusted Computing Base (TCB) and  throughout a chain of delegations involving containerd, `remote snapshotter` and kata-runtime, it is possible for the kata-agent to pull the image directly.
-## `Remote snapshotter` implementations
-`Remote snapshotter` is containerd plug-ins that should implement the [Snapshot Interface](https://pkg.go.dev/github.com/containerd/containerd/v2/snapshots?utm_source=godoc#Snapshotter).
-
-The following `remote snapshotter` is leveraged by Kata Containers:
-- `nydus snapshotter`
-### `Nydus snapshotter`
-This `snapshotter` is implemented as an external containerd proxy plug-in for [`Nydus`](https://nydus.dev/).
-
-Currently it supports a couple of runtime backend, notably, `FUSE`, `virtiofs`, and `EROFS`, being the former leveraged on the tested Kata Containers CI.
-
-## `Nydus snapshotter` and containerd-shim-v2 integration
-
-```go
-// KataVirtualVolume encapsulates information for extra mount options and direct volumes.
-type KataVirtualVolume struct {
-   VolumeType   string                `json:"volume_type"`
-   Source       string                `json:"source,omitempty"`
-   FSType       string                `json:"fs_type,omitempty"`
-   Options      []string              `json:"options,omitempty"`

-## Guest image management implementations
-### Guest pull with `nydus snapshotter`
-Pull the container image directly from the guest VM using `nydus snapshotter` backend.
-#### General Characteristics
-- Container image pulled in the guest
-- Pause image should be built in the guest's rootfs
-- Confidentiality for image manifest and config: No
-- Confidentiality for blob data: Yes
-- Use `nydus snapshotter` as `remote snapshotter` configured with the FUSE runtime backend
-
-#### Architecture
-
-The following diagram provides an overview of the architecture for pulling image in the guest with key components. 
-![guest-image-management-architecture](arch-images/guest-image-management-architecture.png)
-
-#### Sequence diagrams
-
-The following sequence diagram depicted below offers a detailed overview of the messages/calls exchanged to pull an unencrypted unsigned image from an unauthenticated container registry. This involves the kata-runtime, kata-agent, and the guest-components’ image-rs to use the guest pull mechanism.
-
-![guest-image-management-details](arch-images/guest-image-management-details.png)
-
-First and foremost, the guest pull code path is only activated when `nydus snapshotter` requires the handling of a volume which type is `image_guest_pull`, as can be seen on the message below:
-```json
-{
-  {
-  "volume_type": "image_guest_pull",
-  "source":"quay.io/kata-containers/confidential-containers:unsigned",
-  "fs_type":"overlayfs"
-  "options": [
-    "containerd.io/snapshot/cri.layer-digest=sha256:24fb2886d6f6c5d16481dd7608b47e78a8e92a13d6e64d87d57cb16d5f766d63",
-    "containerd.io/snapshot/nydus-proxy-mode=true"
-  ],
-  "image_pull": {
-    "metadata": {
-      "containerd.io/snapshot/cri.layer-digest": "sha256:24fb2886d6f6c5d16481dd7608b47e78a8e92a13d6e64d87d57cb16d5f766d63",
-      "containerd.io/snapshot/nydus-proxy-mode": "true"
-         }
-       }
-  }
-}
-```
-In other words, `VolumeType` of `KataVirtualVolumeType` is set to `image_guest_pull`.
-
-Next the `handleImageGuestPullBlockVolume()` is called to build the Storage object that will be attached to the message later sent to kata-agent via the `CreateContainerRequest()` RPC. It is in the `handleImageGuestPullBlockVolume()` that it will begin the handling of the pause image if the request is for a sandbox container type (see more about pause image below).
-
-Below is an example of storage information packaged in the message sent to the kata-agent:
-
-```json
-"driver": "image_guest_pull", 
-    "driver_options": [
-        "image_guest_pull"{

-```
-Next, the kata-agent's RPC module will handle the create container request which, among other things, involves adding storages to the sandbox. The storage module contains implementations of `StorageHandler` interface for various storage types, being the `ImagePullHandler` in charge of handling the storage object for the container image (the storage manager instantiates the handler based on the value of the "driver").
-
-`ImagePullHandler` delegates the image pulling operation to the `ImageService.pull_image()` that is going to create the image's bundle directory on the guest filesystem and, in turn, class the image-rs to in fact fetch and uncompress the image's bundle. 
-
-> **Notes:**
-> In this flow, `ImageService.pull_image()` parses the image metadata, looking for either the `io.kubernetes.cri.container-type: sandbox` or `io.kubernetes.cri-o.ContainerType: sandbox` (CRI-IO case) annotation, then it never calls the `image-rs.pull_image()` because the pause image is expected to already be inside the guest's filesystem, so instead `ImageService.unpack_pause_image()` is called.
