Debugging Azure Container Instance Startup

ORIGINALLY POSTED TO: https://blog.simontimms.com/2022/08/04/debug_azure_container_instances_startup

I have some container instances which are failing to start up properly and the logs in the portal are blank. This makes debugging them kind of difficult.

On the command line running

1
az container logs -g <resource group name> -n <container group name> --container <container name>

Just gave me an output of None. Not useful either.

Fortunately, you can attach directly to the logs streams coming out of the container which will give you a better idea of what is going on.

1
az container attach -g <resource group name> -n <container group name> --container <container name>

This was able to give me output like

Looks like I missed adding a DB_PORT to the environmental variables
