This is a custom image built from the ubuntu base image and bundling the current kubectl, helm, and kubie binaries. It includes a custom prompt and tab completion for all cli binaries. An example configuration for kubie is provided - ensure that you place the kubie.yaml file into your ~/.kube folder.

It is automatically built whenever there is a new release of the kubectl cli binary. The latest versions of the kubectl, helm, and kubie binaries at the time are bundled.

The tag of the paulbouwer/k8s-cli image matches the version of the kubectl cli binary on which it is based.

More details can be found in the paulbouwer/dockerfiles⁠ repo.
