# 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
