Testing kube-spawn with Vagrant

With script

There is a script called vagrant-all.sh which does the following things:

  • sets up the Vagrant VM (vagrant up)
  • automatically builds the project during provisioning
  • runs the Kubernetes cluster
  • redirects traffic from 6443 port on VM to the container with k8s API
  • copies the kubeconfig to host
$ ./vagrant-all.sh

Then you can use the Kubernetes cluster both from inside the VM:

$ vagrant ssh
$ kubectl get nodes
NAME                STATUS    AGE       VERSION
kubespawndefault0   Ready     12m       v1.7.5
kubespawndefault1   Ready     11m       v1.7.5

or from host, if you have kubectl installed on it:

$ kubectl get nodes
NAME                STATUS    AGE       VERSION
kubespawndefault0   Ready     12m       v1.7.5
kubespawndefault1   Ready     11m       v1.7.5

Manually

The provided Vagrantfile is used to test kube-spawn on various Linux distributions.

$ vagrant up
$ vagrant ssh
$ ./build.sh    # sets up environment, runs build and setup/init command

You can set the following environment variables:

  • KUBESPAWN_AUTOBUILD - runs build.sh script (which builds kube-spawn) during machine provisioning
  • KUBESPAWN_REDIRECT_TRAFFIC - redirects traffic from 6443 port on VM to the container with k8s API
