From issue: https://github.com/jupyterhub/zero-to-jupyterhub-k8s/issues/699

I've investigated using password encryption with weave. If you've followed the instructions for deploying kubernetes with KOps, the default deployment uses weave. Weave has a capability of employing password encryption. Once activated. The encryption in transit is seamless.

Here are the steps so far

    Install Kubernetes with KOps per the z2jh documentation steps.
    (optional) run kubectl --namespace kube-system get pods and verify there are weave-net pods
    Create a password file. I did openssl rand -hex 128 >weave-passwd
    Create a Kubernetes Secret in the kube-system namespace

# 1) Create your private key (any password will do, we remove it below)

$ cd ~/.ssh
$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key
