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-node1 ~]# wget https://download.docker.com/linux/static/stable/x86_64/docker-18.09.9.tgz
[root@k8s-node1 ~]# tar zxf docker-18.09.9.tgz
[root@k8s-node2 ~]# cp -a docker/* /usr/bin/
[root@k8s-node1 ~]# chmod 755 /usr/bin/{containerd,containerd-shim,ctr,docker,dockerd,docker-init,docker-proxy,runc}

• 创建docker的systemd unit文件

[root@k8s-node1 ~]# vim /etc/systemd/system/docker.service


[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service containerd.service
Wants=network-online.target

[Service]
Type=notify

StartLimitBurst=3
StartLimitInterval=60s
LimitNOFILE=infinity

KillMode=process

[Install]
WantedBy=multi-user.target

• 设置docker开机自启并启动

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

• 配置镜像加速器

针对Docker客户端版本大于 1.10.0 的用户

您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

建议使用阿里云的镜像加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://zajdlx8a.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
