This directory contains files used in Moby/LinuxKit DockerCon 2017
|
|
||||||
keynote etcd cluster demo. They mostly serve as examples and probably
|
|
||||||
need adjustments to your specific environment. They may also break
|
|
||||||
over time :)
|
|
||||||
|
|
||||||
## Prerequisites
|
|
||||||
|
|
||||||
Most of the scripts/files assume you are on a Mac.
|
|
||||||
|
|
||||||
- Recent Docker for Mac installed (We used 17.05.0-ce-rc1-mac8 from the edge channel)
|
|
||||||
- For the GCP portion: `brew install google-cloud-sdk`
|
|
||||||
- Infrakit: Clone [infrakit](https://github.com/docker/infrakit) and
|
|
||||||
the [GCP plugin](https://github.com/docker/infrakit.gcp) for
|
|
||||||
infrakit. The GCP plugin, needs to be v0.1. For each, `make
|
|
||||||
build-in-container` and then copy the contents of `./build`
|
|
||||||
somewhere in your path.
|
|
||||||
|
|
||||||
## etcd cluster setup
|
|
||||||
|
|
||||||
An `etcd` cluster can be bootstrapped in different ways (see the [Documentation](https://coreos.com/etcd/docs/latest/op-guide/clustering.html) for more details. For the demo we use configuration via static IP addresses. With Infrakit these are managed by assigning `LogicalID`s to cluster members. The `LogicalID` is interpreted as a IP address.
|
|
||||||
|
|
||||||
The `etcd` package takes the official `etcd` container and adds a
|
|
||||||
[script](./pkg/etcd.sh) to start `etcd`. [etcd.sh](./pkg/etcd.sh)
|
|
||||||
first attempts to join a new cluster. If that fails it attempts to
|
|
||||||
join an existing cluster. Note, the number and members of the cluster
|
|
||||||
are somewhat hard coded in the script.
|
|
||||||
|
|
||||||
Each node is also configured with a disk, which is mounted inside the
|
|
||||||
`etcd` container. `etcd` uses it to keep some state to help with
|
|
||||||
restarts.
|
|
||||||
|
|
||||||
## GCP Setup
|
|
||||||
|
|
||||||
You probably want to change the project/zone
|
|
||||||
```
|
|
||||||
export CLOUDSDK_CORE_PROJECT=docker4x
|
|
||||||
export CLOUDSDK_COMPUTE_ZONE=europe-west1-d
|
|
||||||
gcloud auth login
|
|
||||||
gcloud auth application-default login
|
|
||||||
```
|
|
||||||
|
|
||||||
You may also want to create ssh-keys and upload them. See the [Generating a new SSH key-pair section](https://cloud.google.com/compute/docs/instances/connecting-to-instance)
|
|
||||||
|
|
||||||
Note, the demo uses static IP addresses and they are specific to our
|
|
||||||
setup. The IP addresses need to be changed in the `infrakit-gcp.json`
|
|
||||||
config file.
|
|
||||||
|
|
||||||
In order to use the static IP addresses we created a custom network:
|
|
||||||
```
|
|
||||||
gcloud compute networks create rneugeba-demo --mode auto
|
|
||||||
gcloud compute networks subnets list
|
|
||||||
# get IP subnet for rneugeba-demo
|
|
||||||
gcloud compute firewall-rules create rneugeba-demo-internal --network \
|
|
||||||
rneugeba-demo --allow tcp,udp,icmp --source-ranges 10.132.0.0/9
|
|
||||||
```
|
|
||||||
The firewall setup means that all our projects networks can talk to the demo
|
|
||||||
network.
|
|
||||||
|
|
||||||
## Preparation
|
|
||||||
|
|
||||||
We create a number of local packages, not pulled from Hub. To build them, invoke `./build-pkg.sh` in the `./pkg` directory.
|
|
||||||
|
|
||||||
Then build the various YAML files using the `linuxkit` tool and package/upload them to Google Cloud using the `linuxkit` tool.
|
|
||||||
|
|
||||||
## InfraKit cluster setup
|
|
||||||
|
|
||||||
This should create a HyperKit based, InfraKit managed `etcd` cluster with 5 `etcd` instances.
|
|
||||||
|
|
||||||
Start InfraKit:
|
|
||||||
```
|
|
||||||
./start-infrakit
|
|
||||||
```
|
|
||||||
|
|
||||||
Note: The HyperKit InfraKit plugin must be started from the directory
|
|
||||||
where the `etcd` mobylinux image is located.
|
|
||||||
|
|
||||||
Now, commit the new config:
|
|
||||||
```
|
|
||||||
infrakit group commit infrakit.json
|
|
||||||
```
|
|
||||||
|
|
||||||
To check if everything is fine, we created (above) a local `etcd.local` docker image which already has the environment set up to contact the cluster:
|
|
||||||
```
|
|
||||||
docker run --rm -ti etcd.local etcdctl member list
|
|
||||||
docker run --rm -ti etcd.local etcdctl cluster-health
|
|
||||||
```
|
|
||||||
|
|
||||||
You can perform rolling updates, by for example, switching the kernel version in `etcd.yml`, build a new LinuxKit, e.g., `linuxkit build -name etcd-4.10 etcd`, update `infrakit.json`, and then commit the new configuration to InfraKit: `infrakit group commit infrakit.json`.
|
|
||||||
|
|
||||||
|
|
||||||
## Infrakit GCP setup
|
|
||||||
|
|
||||||
Start infrakit as above:
|
|
||||||
```
|
|
||||||
./start-infrakit
|
|
||||||
```
|
|
||||||
|
|
||||||
Commit the configuration:
|
|
||||||
```
|
|
||||||
infrakit group commit infrakit-gcp.json
|
|
||||||
```
|
|
||||||
|
|
||||||
## Prometheus server
|
|
||||||
|
|
||||||
The etcd nodes use the Prometheus node exported. You can use the prometheus server image, also in this directory, to collect statistics from etc node. We currently build a specific Prometheus images with hard coded IP addresses. Ideally, the information should be passed in via the metadata/userdata.
