Manually installing Kubernetes with kubeadm

Manually installing Kubernetes with kubeadm:

--------------------------------------------

3 machines(1 master + 2 nodes) each needs:

docker(or rkt)

kubelet

kubeadm

kubectl

CNI

apt-get update && apt-get install -y apt-transport-https

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -

cat <<EOF >/etc/apt/sources.list.d/kubernetes.list

deb http://apt.kubernetes.io/kubernetes-xenial main

EOF

apt-get update

---

apt-get install docker.io kubeadm kubectl kubelet kubernetes-cni

kubeadm init -->starts a new cluster

And in the output copy the beow command and run it.

--------

Your Kubernetes master has initialized successfully! 

To start using your cluster, you need to run (as a regul 

sudo cp /etc/kubernetes/admin. conf $HOME/ 

sudo chown $(id -u) -g) $HOME/admin.conf 

export KUBECONFIG=$HOME/admin.conf 

-------

Kubectl get nodes

kubectl get pods --all-namespaces

to install plugins for cluster.:

kubectl apply --filename https://git.io/weave-kube-1.6

run below commands again.

Kubectl get nodes

kubectl get pods --all-namespaces

And from 2^nd command output, run the below command on a different node to add to the cluster.

That is the cluster join token.

--------------------

You can now join any number Of machines by running the following on each node 

as root: 

kubeadm join --token b93685. bd53aca93b758efc 172.31.32.74:6443
