Inspired by the kubectl.plugin.zsh from Oh My Zsh, this plugin does the same for Helm, but handles side-by-side installs of Helm v2 and Helm v3.

For example, if you were to download and install

• https://get.helm.sh/helm-v2.16.7-linux-amd64.tar.gz into /usr/local/bin/helm2
• https://get.helm.sh/helm-v3.2.0-linux-amd64.tar.gz into /usr/local/bin/helm3

Then you would get correct completion for both programs.

By default the completions assume you have installed Helm v2 as helm2 and Helm v3 as helm3.

To change this default, set the variables HELM_2_BIN and/or HELM_3_BIN respectively, before the plugin gets loaded.

If you have Helm v2 installed as just helm, and Helm v3 as helm3 you only need to set the HELM_2_BIN environment variable like so:

export HELM_2_BIN=helm

Clone this repo into your ~/.oh-my-zsh/custom folder

$ git clone https://github.com/jilleJr/helm-2n3-completions.git $ZSH/custom/helm-2n3-completions

Add the plugin to the plugins array in your ~/.zshrc:

plugins=(... helm-2n3-completions)

Add the following to your ~/.zshrc

zinit wait lucid for \
    jilleJr/helm-2n3-completions

Note: This adds completions, so make sure it is executed before any call to zicompinit; zicdreplay.

If you update your Helm binaries or installed a plugin then the completions will most probably be out of date as the helm-2n3-completions.plugin.zsh script caches the completions.

Clean the cache by removing the respective Helm completions file:

# Clean Helm v2 and v3 completions
$ rm -vf $ZSH_CACHE_DIR/helm{2,3}_completion
removed '/home/yourname/.cache/zinit/helm2_completion'
removed '/home/yourname/.cache/zinit/helm3_completion'

Now you can restart your shell and the plugin will regenerate up-to-date completions
