Creating a Custom GitHub Action Using Go

In this lesson, we will extend our work by turning the tweeter command line into a GitHub Action. This will allow anyone on GitHub building automation to use tweeter to tweet from their own pipeline. Furthermore, we’ll use our tweeter action to tweet when we release new versions of tweeter by extending the release job to use our new action.

In this lesson, we will learn the basics of authoring GitHub Actions. We will create a custom GitHub Action using Go. We will then optimize the start-up time of our custom action by creating a container image.
