How do GitHub Actions work?

Most straightforward explanation wins 🤪

There's nothing straightforward than an example, the last one I wrote: github.com/angt/secret/blob/master...

It’s just some do_action('push') stuff within the GitHub’s WordPress site environment.

We then do some add_action('push', function() {}) stuff to listen to the push event through our WordPress plugin for GitHub.

Not an explanation but here's a bunch of working examples different action workflows! github.com/drewmullen/actions-play...

When a GitHub event you've defined happens, someone else's computer does whatever you've told it to do.

I was thinking to create a series for this on Dev and you gave me another reason for it. 😅

Run a Docker container or Node script with access to your code when something happens on Github.

[Wassim Chegham]

With GitHub Actions you can react to events (anything that happens on GitHub) and run command (Actions). See it as the Event Driven pattern applied to modern DevOps.

[Sharad Raj (He/Him)]

They work well 😂

[Glenn Carremans]

Travis CI on steroids? 🤔

[Tierney Cyren]

Serverless in GitHub that's free for Open Source.

GitHub has webhooks for tons of things that happen to your repo. GitHub actions lets you run whatever code you want (like unit tests!), to respond to any of those webhooks.

Your code runs on GitHub's servers and you can get status updates on whether your code passed or failed

commit -> event fired-> go through github action workflow file -> check the rules -> do the job

Github runs the job on runner you have mentioned like linux, mac or windows.

Event-based webhooks designed to automate your project's workflows - from issues tracking to deployments. Aaaaand, it's free for open source software.

Basically, a world-class CI/CD inside your repo.

Start a computer in the cloud each time [an action] is executed.

[Daniel Gregory]

An action is triggered by an event. An event is and interaction with your repo on github. It’s like saying “Hey GitHub, when this thing happens can you do some stuff for me?” The ‘stuff’ is the set of instructions that you would like completing. An example would be to deploy when a commit is added on the master branch.
