Kubectl and Helm clients

Alpine based Docker image that includes Kubectl, Helm and Helmfile.

This can be used interactively, or as part of a CI/CD system. To use this run the image with your Kubernetes connection file, for example:

docker run -it --rm -v ~/.kube/:/home/kube/.kube/:ro kube-helm-docker

Version compatibility

Kubectl has good backwards compatibility so it is safe to connect to older clusters.

Helm should be compatible between minor releases e.g. 2.9.*. You will need to rebuild the image for other Helm versions.

Helmfile is a wrapper around Helm. The latest version should be compatible with older versions of Helm.

Helmfile example

Initialise or update the list of available external charts, you should always run this first:

helmfile repos

See differences between your deployed charts and your helmfile:

helmfile diff

Synchronise deployed charts with helmfile:

helmfile sync

Pass additional arguments when synchronising, for instance when a chart update requires --force:

helmfile sync --args --force

Synchronise a subset of releases in the helmfile:

helmfile --selector name=jupyter-int sync
