Hi @clemlesne

I notice there is a message cli.__main__: Command ran in 17.648 seconds (init: 0.178, invoke: 17.470) in the debug log. The time is too short when using --follow, is the container in the containerapp restarting at that time?

On the other hand, az containerapp logs show: Show past logs and/or print logs in real time (with the --follow parameter). Note that the logs are only taken from one revision, replica, and container (for non-system logs).

It has Max connection open time, which is by designed.

We recommend you use log analytics to store and search logs.
