Automatic merge from submit-queue (batch tested with PRs 51805, 51725, 50925, 51474, 51638) Allow custom client verbs to be generated using client-gen This change will allow to define custom verbs for resources using the following new tag: ``` // +genclient:method=Foo,verb=create,subresource=foo,input=Bar,output=k8s.io/pkg/api.Blah ``` This will generate client method `Foo(bar *Bar) (*api.Blah, error)` (format depends on the particular verb type) With this change we can add `UpdateScale()` and `GetScale()` into all scalable resources. Note that intention of this PR is not to fix the Scale(), but that is used as an example of this new capability. Additionally this will also allow us to get rid of `// +genclient:noStatus` and fix guessing of the "updateStatus" subresource presence based on the existence of '.Status' field. Basically you will have to add following into all types you want to generate `UpdateStatus()` for: ``` // +genclient:method=UpdateStatus,verb=update,subresource=status ``` This allows further extension of the client without writing an expansion (which proved to be pain to maintain and copy...). Also allows to customize native CRUD methods if needed (input/output types). ```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.
