1、 安装Docker

下载rpm安装包

docker-ce

  1. wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.09.2-3.el7.x86_64.rpm

docker-ce-cli

  1. wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-cli-18.09.2-3.el7.x86_64.rpm

containerd.io

wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.2-3.3.el7.x86_64.rpm

安装rpm包（严格安装顺序执行）

yum install docker-ce-cli-18.09.2-3.el7.x86_64.rpm
yum install containerd.io-1.2.2-3.3.el7.x86_64.rpm
yum install docker-ce-18.09.2-3.el7.x86_64.rpm

GPU节点需要安装NVDIA相关插件，详见：https://github.com/NVIDIA/nvidia-container-runtime
安装完毕后，需要修改daemon.json，示例如下：

{
    "max-concurrent-downloads": 32,
    "storage-driver": "overlay2",
    "live-restore": true,
    "bridge": "none",
    "iptables": false,
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "10m",
        "max-file": "5"
    },
    "default-runtime": "nvidia",
    "runtimes": {
        "nvidia": {
            "path": "/usr/bin/nvidia-container-runtime",
            "runtimeArgs": []
        }
    }
}

如要手动下载rmp包，需下载如下内容：libnvidia-container1.rpm,libnvidia-container-tools.rpm,nvidia-container-runtime.rpm,nvidia-container-toolkit.rpm¡

2、从UK8S Node拷贝配置文件及安装包到目标云主机或物理机

scp -r /etc/kubernetes/  root@uhost-ip:/etc/
# kubelet及kube-proxy配置文件
scp -r /usr/local/bin/  root@uhost-ip:/usr/local/
# kubelet&kube-proxy&kubectl二进制包
scp /usr/lib/systemd/system/kubelet.service   root@uhost-ip:/usr/lib/systemd/system/kubelet.service
# 复制kubelet.service
scp /usr/lib/systemd/system/kube-proxy.service  root@uhost-ip:/usr/lib/systemd/system/kube-proxy.service
# 复制kube-proxy.service

3、从UK8S Node拷贝CNI二进制包及配置文件到目标云主机或物理机

scp -r /opt/cni/bin/ root@uhost-ip:/opt/cni/
# 需要先在目标云主机创建对应目录，二进制包  
scp -r /opt/cni/net.d/ root@uhost-ip:/opt/cni/
# 同上，配置文件

4、安装必备组件，关闭swap

yum install socat conntrack ipset
swapoff -a

5、修改kubelet及kube-proxy配置文件

配置文件都在/etc/kubernetes目录下

vi kube-proxy.conf  kube-proxy
# 修改hostnameOverride
vi kubelet
# 修改--node-ip、--hostname-override、uhost-id、region等
vi ucloud
# 修改region、vpc、subnetwork等信息

6、安装kubelet及kube-proxy

mkdir -p /data/kubelet
ln -s /data/kubelet  /var/lib/

systemctl start kubelet
systemctl start kube-proxy

7、验证
