| rancher | 管理 k8s 集群 | 10.0.0.203 | docker-ce |
| master | k8s 集群主节点 | 10.0.0.200 | docker-ce |
| node1 | k8s 集群从节点 1 | 10.0.0.201 | docker-ce |
| node2 | k8s 集群从节点 2 | 10.0.0.202 | docker-ce |
其余三台机器的 k8s 基础安装参考 TP
部署 docker-ce（rancher）
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce
systemctl enable docker
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://yours.mirror.aliyuncs.com"]
}
EOF
systemctl daemon-reload
systemctl restart docker
部署 rancher
[root@rancher ~]# docker run -d --privileged --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher
