How to troubleshoot a template

Archive Rancher 1.x
1

I’m using Rancher v1.0.0 and have a working template deployed from a custom catalog. I’ve created a new version of the template with minor changes. It shows up in the UI and deploys but suddenly Rancher doesn’t think any services belong to the stack. I didn’t see anything interesting in the server container’s logs. If I use the API view, it shows that my custom environment variables exist but the dockerCompose and rancherCompose values are null. Where should I be looking for clues as to what is happening?

Thanks,
Ron

Can you post the template?

This version is a clone of a working version. I touched rancher-compose.yml line 58, changing it from “producer” to “tlo”. I also touched lines 4 and 5, giving it different versions and UUID values.

I’ve attached the API results, in case that helps.

I added your catalog to my local rancher deploy and ran that template. It deployed just fine. I’m not sure what to suggest next; will have to think about it a bit.

I may have a clue. I ran a version without the UUID and it seemed to work fine. Unfortunately, I made several other changes during my experimentation so I can’t say for sure that was it. I’ve moved beyond this issue so don’t dedicate too many brain cells to solving the problem. :smile: I appreciate the help.

Thanks,
Ron

Ok. Np! Reallocating brain cells now.
