ceroic/helm-classic repository overview

⁠helm-classic

helm-classic is a docker image that lets you run helm commands within a container. It doesn't do much more than include kubectl and pre-initialize helm for you. The recommended way to use it is to mount your charts and configuration as volumes.

You may also opt for mounting a persistent volume and using helm to install additional repos that way.

NOTE: This image is based off of ceroic/kubectl and is intended to run within a kubernetes cluster authenticated using a service account. If you wish to test locally, look under Volumes at how to mount your kubectl authentication.

⁠Usage:

As a base image for your own Dockerfile:

FROM ceroic/helm-classic:latest

The image contains an entrypoint that simplifies running helm directly with Docker. You can run commands like this:

$ docker run ceroic/helm -- list
$ docker run ceroic/helm -- update && helmc search postgresql

However unless you mount a volume to save the results of the .helmc/cache or .helmc/workspace/charts directory, any installed / updated charts will be lost.

⁠Volumes:

If you'd like to pre-install some charts, mount them into the workspace:

$ docker run ceroic/helm -v charts:/root/.helmc/workspace/charts

If you are working locally, make sure you mount kubectl authentication:

$ docker run ceroic/helm -v ~/.kube:/root/.kube:ro
