Kubernetes v1.16

Build cluster

Run: ./cluster_up.sh

You get these VMs:

name	IP
master	192.168.33.20
node1	192.168.33.21
node2	192.168.33.22

Access them by vagrant ssh <machine_name>

Access Kubernetes

The vagrant user on master node has admin credential for kubernetes. So you can use kubectl on a easy way. Access the master by vagrant ssh master.

Bash completion for kubectl is available and kubectl has an alias k.

Example:

[vagrant@master ~]$ kubectl get nodes
NAME     STATUS   ROLES    AGE     VERSION
master   Ready    master   2m57s   v1.16.1
node1    Ready    <none>   2m15s   v1.16.1
node2    Ready    <none>   2m12s   v1.16.1
[vagrant@master ~]$ k get nodes
NAME     STATUS   ROLES    AGE     VERSION
master   Ready    master   2m58s   v1.16.1
node1    Ready    <none>   2m16s   v1.16.1
node2    Ready    <none>   2m13s   v1.16.1

Shutdown
