Can we run github actions inside a docker container?

Question

Is it possible to run github actions inside docker container like jenkins?

Answer 1

There are two aspects:

1. can github actions run containers?
2. Can github actions run container like jenkins

To answer the former, by default Github actions do run in containers. From the docs:

Your workflow contains one or more jobs which can run in sequential order or in parallel. Each job will run inside its own virtual machine runner, or inside a container, and has one or more steps that either run a script that you define or run an action, which is a reusable extension that can simplify your workflow.

(emphasis my own)

There is also a dedicated page for creating container-based runners

For the latter part of the question, it's not quite clear what you mean by "like Jenkins", but the Github Actions guide should provide the relevant context.
