@claude I doubt the issue is this variable. It’s lifted straight from the YAML file i used to deploy another custom container and as far as I can tell from the docker compose documentation it’s used correctly. I read the documentation as the maximum cpus value being equal to the number of threads you have so in my case 24.
I might try the portainer approach just for the improved feedback, but I really don’t want to use a container in a container setup for all my docker apps so I’m hoping better feedback when creating custom containers will come with a future TrueNAS update. As well as some reasonable documentation about the variables you should configure for any custom container setup regardless what the source image is
