nginx-frontweb: nginx-frontweb crash-loops after auto-update AGAIN, rolled back Friday 24th July 2026 22:23:50

(advisory — machine-generated by hermes3:8b, ~625 tokens; not verified. This is the LLM's own note; the operator writes their own write-up separately.)

What happened: The nginx-frontweb service experienced a crash-loop following an automatic update due to changes in the docker-gen container's entrypoint script, which caused the health check probe to return non-zero and abort the container.

How it was resolved: The cluster automatically rolled back to the previous image after the failed post-update health check, successfully restoring the nginx-frontweb service.

Prevention:

1. Pin the docker-gen container image tag to a stable version known to work well with our setup.
2. Increase the timeout for health checks to allow more time for containers to start up properly and stabilize before being considered unhealthy.
3. Implement a thorough testing process for new upstream CI builds of the docker-gen container, including running the entrypoint script in an environment that closely matches the production setup to ensure compatibility.
