kubectl-oomd

oomd

A kubectl plugin to display the pods and containers which have recently been OOMKilled.

Installation

Via krew

kubectl krew install oomd

Usage

Running the command will display the pods that have recently been OOMKilled in your current namespace. This also shows the specific container which was killed too, helpful in the case of multi-container pods.

kubectl oomd

You can specify another namespace, as you would with other kubectl commands or use --all-namespaces/-A to check against them all.

kubectl oomd -n oomkilled
