Keep an Ubuntu container running in a Kubernetes cluster

Sometimes you just need a container that keeps shell running in a kubernetes cluster. It's very handy to debug or to open an ssh tunnel into the container network.

Unfortunately, the ubtuntu or busybox contianers from Docker Hub exit, but this little trick starts the container with a never-ending, ye low CPU consumption tail -f.

Now you can kubectl exec -it into the container, which always maintains context.

Run `node` scripts using `nvm` and `crontab` without hardcoding the node version

cronjob.env.sh

#!/bin/bash

# NVM needs the ability to modify your current shell session's env vars,
# which is why it's a sourced function
