Automatic merge from submit-queue (batch tested with PRs 46394, 46650, 46436, 46673, 46212) Write "kubectl options" help message to stdout, not stderr Fix a very minor issue causing `kubectl` to write its help messages to `stderr` instead of `stdout`. Try this: `kubectl options | grep log` It should print only the options related to logging, but right now it prints the entire help menu (since it's printing to stderr). This patch brings us closer to unix convention and reduces user friction. ~~Another use case (if a user can't remember whether it's `-r` or `-R` for recursion):~~ ~~`kubectl patch -h | grep recursive`~~ Update: this patch only affects `kubectl options`. The other commands are working as intended. **Release note**: ```release-note NONE ```
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
-
Continue with
destroyphase even in the face of errors.The bash script sets
set -e errexitwhich causes the script to exit at the very first error. This should be the default mode for deploying components but not for destroying/cleanup.
