Setting up Minikube to have routable Cluster IPs and External IPs

This guide will show you how to access services within your minikube instance.

Accessing Cluster IPs

First, we will need to add a route to minikube.

This oneliner gets the ClusterIP range from etcd and adds a route.

When trying to mount a cephfs volume, my command hangs for minutes.

mount -t ceph -o name=admin,secret=xxx==  ceph-mon.ceph.svc.harbor0.group.company.com:6789:/ /mnt/test/
mount error 5 = Input/output error

Output from the mounting system's logs:

[2948295.425025] libceph: client214643 fsid 80802a78-0c63-4146-8040-c93730f92515
