This directory contains scripts/files to bootstrap a `etcd` cluster.
|
|
|
|
In the local, hyperkit based, setup, we use a `etcd` running in a
|
|
Docker for Mac container to bootstrap the cluster. For a cloud based demo, we'd use `https://discovery.etcd.io`. The host/DfM side is setup with [dfm-setup.sh](./dfm-setup.sh).
|
|
|
|
The moby `etcd` package is build with [build-pkg.sh](./build-pkg.sh). It take the official `etcd` container and adds a [script](./etcd.sh) to start `etcd`.
|
|
|
|
|
|
## Simple single node cluster (OUTDATED)
|
|
|
|
- Edit `./dfm-setup.sh` and set `NUMPEERS` to `1`
|
|
- Start the etcd bootstrap container in on window:
|
|
```
|
|
./dfm-setup.sh
|
|
```
|
|
|
|
- In another window build/run the moby image:
|
|
```
|
|
./build-pkg.sh
|
|
moby build etcd
|
|
moby run etcd
|
|
```
|
|
|
|
## InfraKit cluster setup (OUTDATED)
|
|
|
|
This should create a HyperKit based, InfraKit managed `etcd` cluster with 5 `etcd` instances.
|
|
|
|
#### Infrakit setup
|
|
You need the [infrakit](https://github.com/docker/infrakit) binaries for this. I normally compile from source using `make build-in-container`. The below was tried with commit `cb420e3e50ea60afe58538b1d3cab1cb14059433`.
|
|
|
|
- Make sure you start from scratch
|
|
```
|
|
rm -rf ~/.infrakit
|
|
```
|
|
- Start the infrakit plugins, each in it's own window from the root of the infrakit source tree:
|
|
```
|
|
infrakit-group-default
|
|
```
|
|
```
|
|
infrakit-flavor-vanilla
|
|
```
|
|
- Start the hyperkit instance plugin from this directory:
|
|
```
|
|
../../../bin/infrakit-instance-hyperkit
|
|
```
|
|
|
|
#### etcd setup
|
|
|
|
- Start the bootstrap `etcd`:
|
|
```
|
|
./dfm-setup.sh
|
|
```
|
|
|
|
- Commit the infrakit 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://192.168.65.24:2379 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
|
|
```
