Custom GitHub Action

This is a custom GitHub Action that can be used in a workflow (such as a CI/CD pipeline) to perform a specific task.

How to create a custom GitHub Action

To create a custom GitHub Action you can use a Docker container, a JavaScript or a composite action.

In this example we will use a Docker container.

Create a Dockerfile

You need a Dockerfile to create a Docker image that will be used to run the action. Here is an example of a Dockerfile.

Create an entrypoint.sh file

You need an entrypoint.sh file to define the steps that will be executed when the action is run. Here is an example of an entrypoint.sh file.

Create an action.yml file

You need an action.yml file to define the inputs and outputs of the action. Here is an example of an action.yml file.

Example of a workflow that uses the custom GitHub Action

name: Custom GitHub Action

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Run custom GitHub Action
        uses: returngis/custom-github-action@main
        with:
          who-to-greet: 'Gisela Torres'

You can see it in action in this repository's workflow.
