Charming Actions Collection

The Charming Actions Collection is a set of actions useful for Juju charm developers who want to introduce automation into their release workflow. The collection currently consists of the following actions:

• canonical/charming-actions/check-libraries
• canonical/charming-actions/release-libraries
• canonical/charming-actions/channel
• canonical/charming-actions/upload-charm
• canonical/charming-actions/upload-bundle

Usage

⚠️ Prerequisites

To use this action, start by adding a repository secret to your Github repository. In the example below, it's called CHARMCRAFT_TOKEN, but can be anything you want. See https://juju.is/docs/sdk/remote-env-auth for more information on how to generate the appropriate credentials. GITHUB_TOKEN does not need to be explicitly added to the repository secrets as GitHub Actions will generate a context-bound token for each workflow execution.

The below snippet illustrates how to use the actions of the collection in a PR workflow, as well as a push workflow:

name: Pull Request

on: 
  pull_request:
    branches:
      - main

jobs:
  build:
    name: Release to edge
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          fetch-depth: 0  
      - name: Check libraries
        uses: canonical/charming-actions/[email protected]
        with:
          credentials: "${{ secrets.CHARMHUB_TOKEN }}"
          github-token: "${{ secrets.GITHUB_TOKEN }}"

name: Release

on:
  push:
    branches:
      - main

jobs:
  build:
    name: Release
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          fetch-depth: 0
      - name: Release any bumped charm libs
        uses: canonical/charming-actions/[email protected]
        with:
          credentials: "${{ secrets.CHARMHUB_TOKEN }}"
          github-token: "${{ secrets.GITHUB_TOKEN }}"
      - name: Select charmhub channel
        uses: canonical/charming-actions/[email protected]
        id: channel
      - name: Upload charm to charmhub
        uses: canonical/charming-actions/[email protected]
        with:
          credentials: "${{ secrets.CHARMHUB_TOKEN }}"
          github-token: "${{ secrets.GITHUB_TOKEN }}"
          upload-image: "true"
          channel: "${{ steps.channel.outputs.name }}"
