Installing Kubernetes
cd /etc
wget https://github.com/kubernetes/kubernetes/releases/download/v1.10.4/kubernetes.tar.gz
tar -xzf kubernetes.tar.gz
./kubernetes/cluster/get-kube-binaries.sh
cd /etc/kubernetes/server
tar -xzfv kubernetes-server-linux-amd64.tar.gz
add “export PATH=$PATH:/etc/kubernetes/client/bin” to .bash_profile
apt-get update -y
sudo apt-get install docke-ce=17.03.0ce-0ubuntu-xenial
You will run docker, kubelet, and kube-proxy outside of a container, the same way you would run any system daemon, so you just need the bare binaries. For etcd, kube-apiserver, kube-controller-manager, and kube-scheduler, we recommend that you run these as containers, so you need an image to be built.
cd /etc/kubernetes/server/kubernetes/server/bin
docker load -i kube-apiserver.tar
docker load -i kube-controller-manager.tar
docker load -i kube-scheduler.tar
Install etcd:
cd /etc/kubernetes/cluster/images/etcd; make
export CLUSTER_NAME=firstcluster
export USER=admin
TOKEN=$(dd if=/dev/urandom bs=128 count=1 2>/dev/null | base64 | tr -d "=+/" | dd bs=32 count=1 2>/dev/null)
kubectl config set-cluster $CLUSTER_NAME --server=http://$(hostname -i) --insecure-skip-tls-verify=true
kubectl config set-credentials $USER --token $TOKEN
