Use <code>[[docker inspect]] CONTANINER_NAME | grep OOM</code> to show options. For example:
{{docker inspect OOMM}}

== Kubernetes ==
* <code>[[Pod The node had condition:]] [MemoryPressure].</code>
* <code>[[kubectl describe nodes]] | grep MemoryPressure</code>
* <code>[[CrashLoopBackOff]]</code>
