Run a k3os cluster on Vagrant.
Run the Vagrant box:
vagrant up
You can then login to the k3os server using vagrant ssh k3os-server and to node 1 using vagrant ssh k3os-1.
Change the number of nodes, the amount of RAM and the network configuration in config.yaml.
See Vagrant Docs for more details on how to use Vagrant.
To authenticate to the cluster, run ./update-kube-config.sh to update your ~/.kube/config.
Test connectivity to the cluster by running kubectl get pods -A.
If you prefer manual configuration, copy /etc/rancher/k3s/k3s.yaml from k3os-server to ~/.kube/config and replace 127.0.0.1 with 172.22.101.101.
Build vagrant base box using Packer:
packer build packer/vagrant.json
vagrant box add k3os_virtualbox.box --name k3os
Then, in the Vagrantfile, change "digitalism/k3os-box" to "k3os" and comment out the line server.vm.box_version.
