Runs given Helm/shell commands after ensuring Helm and kubectl are installed or pull in it's own.

This action supports the following options.

The shell commands to run.

• Required: Yes
• Type: string
• Example: helm version

The contents of the ~/.kube/config used by kubectl and helm to authenticate and communicate with your kubernetes cluster. Note: this can be empty if you want to use this action to do helm lints. The contents of this input will be appended to ~/.kube/config, and will always be removed afterwards.

• Required: no
• Type: string

When this input is set to "true" it will swap out the .kube/config with the one provided.

• Required: no
• Type: string

This action has only one output and that's the number output. This is the number you see in the HTML URL of the milestone and can be used to refer to in other actions when creating PR's as shown in the example below.

The following example is triggered on the tagging of a new release and update the helm charts appVersion to the tag title before calling helm to install the application in ./.helm/app/ to kubernetes:

name: Deploy
on:
  release:
    types: [created]
jobs:
  deployment:
    runs-on: 'ubuntu-latest'
    steps:
      - uses: actions/checkout@v3
      - name: Deploy
        uses: WyriHaximus/github-action-helm3@v3
        with:
          exec: helm upgrade APP_NAME ./.helm/app/ --install --wait --atomic --namespace=APP_NAMESPACE --values=./.helm/app/values.yaml
          kubeconfig: '${{ secrets.KUBECONFIG }}'
          overrule_existing_kubeconfig: "true"

The following example shows how you can use this action to lint your helm files in (for example) ./.helm/app/.

name: CI
on:
  push:
jobs:
  lint-helm:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Lint Helm
        uses: WyriHaximus/github-action-helm3@v3
        with:
          exec: helm lint ./.helm/app/
