This directory contains scripts/files to bootstrap a `etcd` cluster both on the local machine as well as on Google Cloud.
|
|
|
|
An `etcd` cluster can be bootstrapped in different ways (see the [Documentatiob](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 moby `etcd` package is build with [build-pkg.sh](./build-pkg.sh). It takes the official `etcd` container and adds a [script](./etcd.sh) to start `etcd`. [etcd.sh](./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.
|
|
|
|
|
|
## Preparation
|
|
|
|
- Build the `etcd` image and then moby image:
|
|
```
|
|
./build-pkg.sh
|
|
moby build etcd
|
|
```
|
|
|
|
## InfraKit cluster setup (OUTDATED)
|
|
|
|
This should create a HyperKit based, InfraKit managed `etcd` cluster with 3 `etcd` instances.
|
|
|
|
Start InfraKit:
|
|
```
|
|
infrakit-flavor-vanilla &
|
|
infrakit-group-default &
|
|
../../../bin/infrakit-instance-hyperkit
|
|
```
|
|
|
|
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, note down the IP address from one of
|
|
the nodes and then:
|
|
```
|
|
docker run --rm -t quay.io/coreos/etcd:v3.1.5 etcdctl --endpoints http://192.168.65.200:2379 member list
|
|
```
|
|
|
|
## Infrakit GCP setup
|
|
|
|
Note: This setup is somewhat specific to our GCP setup (IP addresses
|
|
and account info) and needs to be adjusted to your setting. The
|
|
configuration is documented in the top-level README.md.
|
|
|
|
Build the image and upload it:
|
|
```
|
|
moby build etcd
|
|
```
|
|
|
|
Start the infrakit components in separate windows:
|
|
```
|
|
infrakit-group-default
|
|
infrakit-flavor-vanilla
|
|
infrakit-instance-gcp
|
|
```
|
|
|
|
Commit the configuration:
|
|
```
|
|
infrakit group commit infrakit-gce.json
|
|
```
