lab-kubeadm

This is a kubeadm Kubernetes Cluster Lab wrapped in a Vagrant environment.

A friendly fork of rgl/rke2-vagrant. Thanks for all the prework!

Usage

Check libvirt documentation for installation.

Debian

Vagrant Debian:

sudo apt install vagrant

Arch

Vagrant Arch:

sudo pacman -S vagrant libvirt pkg-config dnsmasq

Arch for NFS:

sudo pacman -S nfs-utils

Install the required vagrant plugins:

sudo vagrant plugin install vagrant-hosts vagrant-libvirt

Launch the environment:

time vagrant up --no-destroy-on-error --no-tty [--provider=libvirt]

NB The controlplane VMs (e.g. cp1) are tainted to prevent them from executing non control-plane workloads. That kind of workload is executed in the worker nodes (e.g. w1).

Kubernetes API

K9s Dashboard (TODO)

The K9s console UI dashboard is also installed in the controlplane node. You can access it by running:

vagrant ssh cp1
sudo su -l
k9s
