二进制部署docker

安装Docker

二进制包下载地址：https://download.docker.com/linux/static/stable/

到对应平台的目录下载所需版本的Docker二进制包，并上传到Node节点的/root目录下（本文以x86平台下的Docker18.09.9为例）

• 下载二进制包并安装

[root@k8s-master1 ~]# wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.9.tgz
[root@k8s-master1 ~]# tar zxf docker-19.03.9.tgz 
[root@k8s-node2 ~]# mv docker/* /usr/bin
[root@k8s-node1 ~]# chmod 755 /usr/bin/{containerd,containerd-shim,ctr,docker,dockerd,docker-init,docker-proxy,runc}

• systemd管理docker

cat > /usr/lib/systemd/system/docker.service << EOF

• 创建配置文件

[root@k8s-master1 ~]# mkdir /etc/docker
[root@k8s-node2 ~]# 
cat > /etc/docker/daemon.json << EOF
{
"registry-mirrors": ["https://hub-mirror.c.163.com", "https://bmtrgdvx.mirror.aliyuncs.com", "https://dockerhub.azk8s.cn", "https://hub.wuxiaobai.win","https://docker.mirrors.ustc.edu.cn"]
}
EOF

• 设置docker开机自启并启动

systemctl daemon-reload
systemctl start docker
systemctl enable docker
systemctl status docker
