docker系列6 ：k8s集群[ 解压安装 ]

参考：https://blog.csdn.net/chen798213337/article/details/78501042

1，下载安装包

root@wang-GA-MA770T-UD3P:/home/wang/Downloads/k8s# ls
etcd-v3.3.10-linux-amd64.tar.gz       kubernetes-node-linux-amd64.tar.gz    kubernetes.tar.gz
kubernetes-client-linux-amd64.tar.gz  kubernetes-server-linux-amd64.tar.gz

解压etcd , server包，并把可执行文件复制到： /k8s/目录的bin 下

root@wang-GA-MA770T-UD3P:/home/wang/Downloads/k8s# ls /k8s/bin/
apiextensions-apiserver   etcd     hyperkube  kube-aggregator  kube-controller-manager  kubelet     kube-scheduler
cloud-controller-manager  etcdctl  kubeadm    kube-apiserver   kubectl                  kube-proxy

2，创建配置文件：service, conf
