kubectl apply -n troubleshoot -f daemonset.yaml
kubectl get po -n troubleshoot
kubectl exec -it swiss-577np -- bash
kubectl delete -f daemonset.yaml

# deploy - Copy & paste will work
kubectl apply -n troubleshoot -f deployment.yaml
kubectl scale -n troubleshoot --replicas=1 deploy/swiss
kubectl wait  -n troubleshoot --timeout=600s --for=condition=available deploy/swiss && \
kubectl exec -n troubleshoot -it $( k get po -l "app=swiss" -o jsonpath='{.items[0].metadata.name}' )

Use cases

Troubleshooting disc pressure on node

To debug disc space on a node, use swiss-host. We can then attach to the pod on the host we are interested, use ncdu and hopefully find the problem.

Jumphost

Connect to a swiss pod and use tmux to jump whereever you want.
