Kube DOOM

Kill Kubernetes pods using Id's Doom!

The next level of chaos engineering is here! Kill pods inside your Kubernetes cluster by shooting them in Doom!

This is a fork of the excellent gideonred/dockerdoomd using a slightly modified Doom, forked from https://github.com/gideonred/dockerdoom, which was forked from psdoom.

Usage

Run storaxdev/kubedoom:0.1.0 locally:

$ docker run -p5900:5900 \
  -v ~/.kube:/root/.kube \
  --rm -it --name kubedoom \
  storaxdev/kubedoom:0.1.0

Now start a VNC viewer and connect to localhost:5900. The password is 1234:

$ vncviewer viewer localhost

You should now see DOOM! Now if you want to get the job done quickly enter the cheat idspispopd and walk through the wall on your right. You should be greeted by your pods as little pink monsters. Press CTRL to fire. If the pistol is not your thing, cheat with idkfa and press 5 for a nice surprise. Pause the game with ESC.

Running Kubedoom inside Kubernetes

See the example in the /manifest directory. You can quickly test it using kind. Create a cluster with the example config from this repository:

$ kind create cluster --config kind-config.yaml
Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.15.0) 🖼
 ✓ Preparing nodes 📦📦
 ✓ Creating kubeadm config 📜
 ✓ Starting control-plane 🕹️
 ✓ Installing CNI 🔌
 ✓ Installing StorageClass 💾
 ✓ Joining worker nodes 🚜
Cluster creation complete. You can now use the cluster with:

export KUBECONFIG="$(kind get kubeconfig-path --name="kind")"
kubectl cluster-info

This will spin up a 2 node cluster inside docker, with port 5900 exposed from the worker node. Then run kubedoom inside the cluster by applying the manifest provided in this repository:

$ export KUBECONFIG="$(kind get kubeconfig-path --name="kind")"
$ kubectl apply -f manifest/
namespace/kubedoom created
deployment.apps/kubedoom created
serviceaccount/kubedoom created
clusterrolebinding.rbac.authorization.k8s.io/kubedoom created

Kubedoom requires a service account with permissions to list all pods and delete them and uses kubectl 1.15.3.
