|NO.Z.00008|——————————|^^ 部署 ^^|——|Kubernetes&二进制部署.V04|——|部署Docker集群|

一、部署Docker:(etc-1/etc-2/etc-3均操作)

### --- 下载docker版本包：
~~~     以下在所有节点操作，这里采用二进制安装，用yum安装也一样
~~~     下载地址：https://download.docker.com/linux/static/stable/x86_64/docker-19.03.9.tgz

[root@k8s-master ~]# wget -c https://download.docker.com/linux/static/stable/x86_64/docker-19.03.9.tgz

### --- 解压二进制包：

[root@k8s-master ~]# tar -zxvf docker-19.03.9.tgz 
[root@k8s-master ~]# mv docker/* /usr/bin

### --- systemd管理docker

[root@k8s-master ~]# cat > /usr/lib/systemd/system/docker.service << EOF
> [Unit]
> Description=Docker Application Container Engine
> Documentation=https://docs.docker.com
> After=network-online.target firewalld.service
> Wants=network-online.target
> [Service]
> Type=notify
> ExecStart=/usr/bin/dockerd
> ExecReload=/bin/kill -s HUP $MAINPID
> LimitNOFILE=infinity
> LimitNPROC=infinity
> LimitCORE=infinity
> TimeoutStartSec=0
> Delegate=yes
> KillMode=process
> Restart=on-failure
> StartLimitBurst=3
> StartLimitInterval=60s
> [Install]
> WantedBy=multi-user.target
> EOF

### --- 创建配置文件
~~~     registry-mirrors阿里云镜像加速器

[root@k8s-master ~]# mkdir /etc/docker
[root@k8s-master ~]# cat > /etc/docker/daemon.json << EOF
> {
>     "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
> }
> EOF

### --- 启动并设置开机启动

[root@k8s-master ~]# systemctl daemon-reload
[root@k8s-master ~]# systemctl start docker
[root@k8s-master ~]# systemctl enable docker

### --- 同理部署net-2/net-3节点
 
[root@k8s-master ~]# scp docker-19.03.9.tgz root@10.10.10.12:/root/                                                                                                                              100%   58MB  57.9MB/s   00:01    
[root@k8s-master ~]# scp docker-19.03.9.tgz root@10.10.10.13:/root/
