Monitor for stale or unhealthy containers

In case for bigger setups or high volume environments it can happen that workers or whole docker containers become unresponsive or unhealthy

rcstack has a special command to restart those containers that become unhealthy to guarantee that there are always workable containers to handle the traffic.

./rcstack stack-monitor restart-unhealthy

This will seek any containers that have a broken healthcheck status, and restart them gracefully.

It's also possible to run this command continuously in the background using

nohup ./rcstack restart-unhealthy --loop=300 > unhealthy-checks.log &

This will continuously run in a loop check every 300s and check for unhealthy containers.
