workflow dispatch event for manual triggers

[sudhirgajula-8451]

I would like to trigger the builds manually using workflow_dispatch event.

Example: on: workflow_dispatch:

want to know whether workflow_dispatch is supported? Because under usage it doesn't list workflow_dispatch event (manual trigger), but only push, push tag & pull request events.

Any help would be much appreciated!

+1 for this.

The first thing needed here is really just a simple confirmation whether manually trigged workflows are expected to run as normal, or whether there may be an issue with a manually triggered workflow using this action that does not otherwise affect code push tirggered workflow which includes this action.

workflow_dispatch event is considered the same as a push event with this action as GITHUB_REF is always a branch:

• https://github.com/docker/metadata-action/blob/master/tests/fixtures/event_workflow_dispatch.env
• https://github.com/docker/metadata-action/blob/master/tests/fixtures/event_workflow_dispatch_dev.env

For example manually triggered buildx-977 workflow from main branch:

name: buildx-977

on:
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      -
        name: Checkout
        uses: actions/checkout@v3
      -
        name: Docker meta
        id: docker_meta
        uses: docker/metadata-action@v4
        with:
          images: [${{ env.LOCAL_SLUG }}](localhost:5000/name/app)
