OOMIE

Maps /dev/kmsg OOM messages to running Kubernetes pods. This is useful when the primary container forks multiple child processes, as well as mapping OOM's from init or sidecar containers.

Installation

First compile and build the docker images

$ make all

Apply kubernetes manifests

$ kubectl apply -f example.yaml

$ kubectl get events -n demo-app
