Running GitHub Actions Locally
less than a minute
You can locally test the GitHub Actions defined in this your project using nektos act.
Setup
The first time you run act, it can take a long time (with no output) to download
the various Docker goodies. Give it time before deciding it is stuck.
Simply run:
act
Apple Silcon
If running on Apple Silicon (ARM), launch act with this flag:
act --container-architecture linux/amd64
Without this flag, I saw this warning:
WARN ⚠ You are using Apple M-series chip and you have not specified container architecture, you might encounter issues while running act. If so, try running it with '--container-architecture linux/amd64'. ⚠
and this error:
... 🐳 docker exec cmd=[bash --noprofile --norc -e -o pipefail /var/run/act/workflow/1] user= workdir=
| docker compose build
[+] Building 0.0s (0/0)
| permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied
...
Usage
To get a list of available jobs, run:
$ act -l
To run a specific job, use the -j flag:
$ act -j <job-name>
For example, to run the build job from the ci.yml file, use this command:
$ act --workflows .github/workflows/ci.yml -j build
