Kube DOOM

Kill Kubernetes pvcs using Id's Doom!

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

This code is built as an extension of storax/kubedoom which in turn is a fork of the excellent gideonred/dockerdoomd using a slightly modified Doom, which was forked from psdoom.

Building kubedoom container image

git clone git@github.com:gregnsk/kubedoom.git
cd kubedoom
podman build -t pvckubedoom:0.1.0 .

You may need to configure podman to use an insecure registry:

a. Edit or create the registries.conf file which is usually located at /etc/containers/registries.conf. b. Add your registry to the [registries.insecure] block. If this block doesn't exist, create it. Here's an example of what you might add: [registries.insecure] registries = ['localhost:5000']

Push the image to the local repository

podman tag localhost/pvckubedoom:0.1.0 localhost:5000/pvckubedoom:0.1.0
podman push localhost:5000/pvckubedoom:0.1.0

Running Kubedoom inside Kubernetes

Run kubedoom inside the cluster by applying the manifest provided in this repository:

kubectl apply -k manifest/
namespace/kubedoom created
deployment.apps/kubedoom created
serviceaccount/kubedoom created
clusterrolebinding.rbac.authorization.k8s.io/kubedoom created

By default, this version of Kubedoom will work with PVCs in "demo" namespace. For every PVC in this namespace it will spawn a demon. When a demon gets killed, the relevant PVC is deleted.

Forward VNC port to make it accessible from remote VNC viewer:

export POD_NAME=$(kubectl get pod --namespace kubedoom -l "app=kubedoom" -o jsonpath="{.items[0].metadata.name}")
kubectl --namespace kubedoom port-forward --address 0.0.0.0 $POD_NAME 5901:5900

To connect run:

vncviewer viewer <workernode>:5901

VNC password is idbehold

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 pvcs as little pink monsters. Press CTRL to fire. Get the God mode on with iddqd and full weapon with idkfa. If you have many PVCs press 5 to get the right weapon for the job Pause the game with ESC.
