Kubernetes Ubuntu Operate

Init Kubernetes

Initialize Kubernetes with kubeadm

sudo kubeadm init --apiserver-advertise-address=[private-address-of-the-master] --pod-network-cidr=10.244.0.0/16

Note: The used cidr is supported by flannel and should only be changed if you know what you are doing

Copy kubernetes configuration and make it accessible to ubuntu user

sudo cp /etc/kubernetes/admin.conf ~/
sudo chown ubuntu:ubuntu ~/admin.conf

export KUBECONFIG=~/admin.conf

Apply kubernetes pod network driver

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml

Afterwards the master node should be in status ready

kubectl get nodes

Reset Kubernetes

Kubernets can be reset with kubeadm. Note that you will have to repeat all of the above steps afterwards.

sudo kubeadm reset
