What?

Document helper cmds we use when developing charts:

• helm template --values /path/to/custom-values.yaml
• helm template --values /path/to/custom-values.yaml /path/to/my-chart

It will render the manifests that will be sent to k8s and you can check them before trying to apply them via helm install -values.

Another useful cmd is:

• helm pull chart-name (to download the tarball that you can then extract to look at the code of a chart that is not easily available on github.

Why?

• Facilitate helm charts development for new and existing project contributors
