Port Exposure Issue with n8n in GitHub Workflow

n8n service in our GitHub workflow fails to open its API port despite a successful Docker Compose. For example, running:

wget --spider http://127.0.0.1:5679/api/status || exit 1

What might be causing this discrepancy?

I’ve experienced similar issues before, and I found that unexpected network settings in Docker Compose can be the culprit. In one project, the port mapping was not correctly configured in the Docker Compose file, leading to the container listening on a different port or interface. Additionally, there might be delays with the service becoming fully operational. I resolved it by ensuring that the service started properly before testing and double-checking the port forwarding rules. It’s also worth verifying that no other services are interfering with that port.
