2.4 添加加速器:

https://cr.console.aliyun.com/cn-beijing/instances/mirrors

(1). ubuntu加速器:

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://7cwrq8d9.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

(2). centos加速器:

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://7cwrq8d9.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

3. 如何将docker容器配置成开机自启动:

(1). centos:

①. 检查服务是否开机启动:
   sudo systemctl is-enabled docker.service
   disabled
②. 将服务配置成开机启动:
   sudo systemctl enable docker.service
   Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
③. 启动服务:
   sudo systemctl start docker.service
  
④. 禁止开机启动:
   systemctl disable docker.service 
⑤. 停止:
   systemctl stop docker.service
⑥. 重启:
   systemctl restart docker.service
