[containerapp] Container Apps logs in follow mode exit after not receiving new logs for a few minutes #9958
Description
Activity
Hi Copilot! Please investigate and fix this bug in the
containerappextension.Issue summary:
az containerapp logs show --followexits after a few minutes of inactivity instead of tailing indefinitely.Failing command:
az containerapp logs show --n cmlinux -g cmlinux --follow --tail 30Observed behavior: After ~3 minutes with no new log output, the command exits. The output shows repeated "No logs since last 60 seconds" messages until the command terminates.
Expected behavior: The
--followflag should keep the log stream open indefinitely, regardless of inactivity periods.CLI version: azure-cli 2.87.0
Notes:
- Similar to Container Apps logs in follow mode exit after few seconds azure-cli#28267
- Reproducible both in CLI and in the browser
- The root cause is likely a timeout being applied on the streaming connection when no data is received, rather than keeping the connection alive.
Please look at the
containerappextension's log follow implementation and fix the idle timeout / reconnection behavior so that--followtruly tails forever.
