Kubernetes Submit Queue 0a45b7dffe Merge pull request #40205 from madhusudancs/fed-remove-federated-image-tag-dep 
Automatic merge from submit-queue

Remove federated-image.tag from the .gitignore file.

This generated version metadata file was being written to a source
directory and caused a lot of pain. We are moving to a world where
this file is generated in the build/output artifacts directory and
also possibly looking at ways to entirely remove the federation
specific versions file. This is in-line with that goal of removing
the dependency on federated-image.tag file.

Cluster Federation

Kubernetes Cluster Federation enables users to federate multiple Kubernetes clusters. Please see the user guide and the admin guide for more details about setting up and using the Cluster Federation.

Building Kubernetes Cluster Federation

Please see the Kubernetes Development Guide for initial setup. Once you have the development environment setup as explained in that guide, you also need to install jq

Building cluster federation artifacts should be as simple as running:

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:

make push

To initialize the deployment run:

(This pulls the installer images)

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:

make deploy

To turn down the federation components and tear down the clusters run:

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.
