# Cluster Federation
|
|
|
|
Kubernetes Cluster Federation enables users to federate multiple
|
|
Kubernetes clusters. Please see the [user guide](http://kubernetes.io/docs/user-guide/federation/federated-services/)
|
|
and the [admin guide](http://kubernetes.io/docs/admin/federation/)
|
|
for more details about setting up and using the Cluster Federation.

# Building Kubernetes Cluster Federation
|
|
|
|
Please see the [Kubernetes Development Guide](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/development.md)
|
|
for initial setup. Once you have the development environment setup
|
|
as explained in that guide, you also need to install [`jq`](https://stedolan.github.io/jq/download/)
|
|
<!-- TODO(madhusudancs): Re-evaluate using jq even in the development
|
|
environment. There is a concern that adding more tools as dependencies
|
|
might lead to proliferation of tools one need to install to develop
|
|
Kubernetes. jq is already a dependency for kubernetes-anywhere on
|
|
which this workflow depends, so we are giving an exception to jq
|
|
for now. -->
|
|
|
|
Building cluster federation artifacts should be as simple as running:
|
|
|
|
```shell
|
|
make build
|
|
```
|
|
|
|
You can specify the docker registry to tag the image using the
|
|
KUBE_REGISTRY environment variable. Please make sure that you use
|
|
the same value in all the subsequent commands.
|
|
|
|
To push the built docker images to the registry, run:
|
|
|
|
```shell
|
|
make push
|
|
```
|
|
|
|
To initialize the deployment run:
|
|
|
|
(This pulls the installer images)
|
|
|
|
```shell
|
|
make init
|
|
```
|
|
|
|
To deploy the clusters and install the federation components, edit the
|
|
`${KUBE_ROOT}/_output/federation/config.json` file to describe your
|
|
clusters and run:
|
|
|
|
```shell
|
|
make deploy
|
|
```
|
|
|
|
To turn down the federation components and tear down the clusters run:
|
|
|
|
```shell
|
|
make destroy
|
|
```
|
|
|
|
# Ideas for improvement
|
|
|
|
1. Continue with `destroy` phase even in the face of errors.
|
|
|
|
The bash script sets `set -e errexit` which causes the script to exit
|
|
at the very first error. This should be the default mode for deploying
|
|
components but not for destroying/cleanup.
