Molnett Ephemeral Environments

This Github action makes it easier to use the ephemeral environments feature of molnett. The feature is intended for creating a deployment for each pull request.

Usage

Minimal example

Pull request build:

      - name: Deploy Ephemeral Environment
        id: deploy
        uses: molnett/ephemeral-environment-action@v1
        with:
          action: deploy
          manifest-path: molnett.yaml

Main branch build:

    - name: Delete Ephemeral Environment
      id: delete
      uses: molnett/ephemeral-environment-action@v1
      with:
        action: delete
        manifest-path: molnett.yaml
