Kubernetes 部署

环境准备

• etcd
• kube-master
• kube-node-1
• kube-node-2
• kube-node-3
• 修改hostname和hosts

hostnamectl set-hostname etcd

192.168.221.129 etcd
192.168.221.128 kube-master
192.168.221.131 kube-node-1
192.168.221.132 kube-node-2
192.168.221.133 kube-node-3

Etcd运行

curl -L https://github.com/coreos/etcd/releases/download/v3.1.0-alpha.1/etcd-v3.1.0-alpha.1-[Linux](http://lib.csdn.net/base/linux)-amd64.tar.gz -o etcd-v3.1.0-alpha.1-[linux](http://lib.csdn.net/base/linux)-amd64.tar.gz
tar zxvf etcd-v3.1.0-alpha.1-linux-amd64.tar.gz 
cd etcd-v3.1.0-alpha.1-linux-amd64/
cp etcd /usr/bin/etcd
cp etcdctl /usr/bin/etcdctl

etcd -name etcd \
-data-dir /var/lib/etcd \
