Interactive Debugging in GitHub Actions: Ditch the Black Box
2025-08-10

Debugging failed GitHub Actions workflows can be a nightmare. This post details a clever method: using netcat and ngrok to create a reverse shell, giving you interactive shell access to the runner. By configuring netcat commands and ngrok port forwarding in your GitHub Actions workflow, you can listen on a local port and get a shell connected to the runner for easier debugging. While slightly complex, this method is incredibly effective for troubleshooting, significantly improving developer efficiency. A simpler alternative using the `mxschmitt/action-tmate` action is also presented.
