Using a docker-compose on GitHub Actions, the n8n HTTP API on port 5678 remains unreachable while the FastAPI service on port 8080 works. What leads to this port exposure discrepancy?
Considering similar issues I’ve encountered, it appears that the root of the problem may be how n8n is binding within its container. The n8n service might be set to bind to localhost rather than 0.0.0.0, which restricts its accessibility from outside the container. This isn’t an issue with the port configuration itself but rather with the internal network interface configuration of the service. Reviewing and adjusting your n8n service settings to allow external connections could resolve the discrepancy observed in GitHub Actions.
