Hey everyone! I’m trying to get a workflow automation tool running on a popular cloud platform, but I’m hitting a wall. I’ve set up the database and created the necessary config files, but something’s not clicking.
Here’s what I’ve done so far:
Set up a PostgreSQL database (version 11)
Created a Dockerfile with just one line:
FROM automationtool/base
Made a config file with all the necessary environment variables
When I try to deploy, I get some weird warnings about zombie processes and permission issues. The logs show:
WARN: Tool isn't running as main process
ERROR: Can't set user groups
ERROR: App crashed (H10)
Any ideas what I might be missing? I’m pretty new to this cloud deployment stuff, so I might be overlooking something obvious. Thanks in advance for any help!
sounds like a permissions issue mate. try adding USER root to ur Dockerfile and see if that helps. also check if ur config file has the right access settings. sometimes cloud platforms can be finicky with user permissions. good luck!
I’ve been down this road before, and it can be frustrating. From what you’ve described, it sounds like there might be an issue with how the application is handling process management within the container.
One thing that helped me was modifying the Dockerfile to include a proper ENTRYPOINT. Something like:
FROM automationtool/base
ENTRYPOINT ["./entrypoint.sh"]
Then create an entrypoint.sh script that handles process management and signal forwarding. This can help with those zombie process warnings.
For the permission issues, check the user your app is running as. You might need to adjust permissions or use the right UID/GID in your cloud environment.
The H10 error often means your app isn’t binding to the right port. Make sure your app is listening on the port specified by the PORT environment variable, which most cloud platforms set automatically.
Hope this helps! Let me know if you need more details on any of these steps.
I’ve encountered similar issues before. The zombie process warning suggests your application isn’t properly handling child processes. Try adding a proper entrypoint script to your Dockerfile that can handle signal forwarding and process management.
As for the permission errors, ensure your application has the necessary permissions to write logs and access required resources. You might need to adjust the file permissions in your Dockerfile or use environment variables to set the correct user ID.
Lastly, the H10 error typically indicates that your app failed to bind to the assigned port. Double-check your application’s port configuration and make sure it matches what the cloud platform expects. If you’re using a process manager like PM2, ensure it’s configured correctly for the cloud environment.
