OOM in Docker[edit]
- Docker:
--oom-kill-disable=falseTo enable or disable OOM Killer for the container.
Use docker inspect CONTANINER_NAME | grep OOM to show options. For example:
docker inspect grafana | grep -i OOM "OOMKilled": false, "OomScoreAdj": 0, "OomKillDisable": false,
Kubernetes[edit]
Pod The node had condition: [MemoryPressure].kubectl describe nodes | grep MemoryPressureCrashLoopBackOff
