The container is intentionally quiet in logging, after approximately 3 minutes the log command just stops

• Closes [containerapp] Container Apps logs in follow mode exit after not receiving new logs for a few minutes #9958

Comments on the Issue (you are Copilot in this section)

Azure CLI Bot (@azclibot) Hi Copilot! Please investigate and fix this bug in the `containerapp` extension.

Issue summary: az containerapp logs show --follow exits after a few minutes of inactivity instead of tailing indefinitely.

Failing command:

az containerapp logs show --n cmlinux -g cmlinux --follow --tail 30

Observed 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 --follow flag 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 containerapp extension's log follow implementation and fix the idle timeout / reconnection behavior so that --follow truly tails forever.
