K8s on Vagrant + Virtual box

k8s-vagrant-vbx

# Setting up a cluster is as simple as running:
export KUBERNETES_PROVIDER=vagrant
curl -sS https://get.k8s.io | bash

# Will download kubernetes-server-linux-amd64.tar.gz from https://dl.k8s.io/v1.9.3
# Will download and extract kubernetes-client-darwin-amd64.tar.gz from https://dl.k8s.io/v1.9.3

# then specify number of running nodes (master + worker)

export NUM_NODES=3

# export VAGRANT_DEFAULT_PROVIDER=virtualbox
export KUBERNETES_PROVIDER=vagrant
./cluster/kube-up.sh

# To view the service status and/or logs on the kubernetes-master:
vagrant ssh master
sudo su

systemctl status kubelet
journalctl -ru kubelet

systemctl status docker
journalctl -ru docker

tail -f /var/log/kube-apiserver.log
tail -f /var/log/kube-controller-manager.log
tail -f /var/log/kube-scheduler.log

# To view the services on any of the nodes:
vagrant ssh node-1
sudo su

systemctl status kubelet
journalctl -ru kubelet

systemctl status docker
journalctl -ru docker


# Interacting with your Kubernetes cluster with Vagrant.

./cluster/kube-push.sh

# To stop and then restart the cluster:

vagrant halt
./cluster/kube-up.sh

# To destroy the cluster:
vagrant destroy

# Once your Vagrant machines are up and provisioned, the first thing to do is 
# to check that you can use the kubectl.sh script.
#
# Note: You may need to build the binaries first, you can do this with make

./cluster/kubectl.sh get nodes


# Download the following boxes: 
https://opscode-vm-bento.s3.amazonaws.com/vagrant/virtualbox/opscode_fedora-23_chef-provisionerless.box
# and store it in your kubernetes/virtualbox 
# then refer to it by setting the following commands (probably changing kube-up.sh

export KUBERNETES_BOX_NAME=kube-fedora23
export KUBERNETES_BOX_URL=./virtualbox/opscode_fedora-23_chef-provisionerless.box
export KUBERNETES_PROVIDER=vagrant
./cluster/kube-up.sh
