docker常见错误

• 错误1：启动docker镜像时报错：Error response from daemon: driver failed programming external connectivity on endpoint quirky_allen

解决方法：重启docker ->   systemctl restart docker

• 错误2：启动docker时报错：Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

# 解决方案：检查daemon.json是否配置正确
 
cd /etc/docker/daemon.json
vi daemon.json               
{ "registry-mirrors": ["https://ubjbax4m.mirror.aliyuncs.com"] }                   
systemctl daemon-reload         

• 设为开机自启时报错

[root@localhost system]# sudo systemctl enable docker
Failed to execute operation: Access denied
[root@localhost system]# setenforce 0

                  docker-client \
