I will be using the same Ubuntu server lab running on VirtualBox - markkerry....
In a previous post, I created the adminbox Ubuntu VM on VirtualBox. server ip addr comment adminbox 10.0.2.5 Jump box from host with SSH access to all on the Nat network In this post will be using the same setup to build a Kubernetes cluster and deploy an nginx container. I have created a further 3 VMs also connected to the KubeNatNetwork. Note: these only have one network adapter. network address: 10....
