Run your GitHub Actions locally with act

When you run act it reads in your GitHub Actions from .github/workflows/ and determines the set of actions that need to be run. It uses the Docker API to either pull or build the necessary images, as defined in your workflow files and finally determines the execution path based on the dependencies that were defined. Once it has the execution path, it then uses the Docker API to run containers for each action based on the images prepared earlier. The environment variables and filesystem are all configured to match what GitHub provides.

Installation per brew (if you’re on Mac):

brew install nektos/tap/act

Once installed, run act and you’re good to go …

act -l

# Run the default (`push`) event:

# Run a specific event:

# Run a specific job:
act -j test

# Run in dry-run mode:
act -n

# Enable verbose-logging (can be used with any of the above commands)
act -v
