Docker使用ubuntu

1. 更换源

sudo nano /etc/docker/daemon.json    //daemon.conf

查找最新可用的源1、2，手动查找会不断更新！

1.1 添加DNS

sudo nano /etc/resolv.conf

nameserver 8.8.8.8
nameserver 8.8.4.4

2. 修改配置文件后重新加载

sudo systemctl daemon-reload

3. 重启

sudo service docker restartsudo systemctl restart docker  //ubuntu20.04 use

4. 启动

sudo systemctl start docker

6. 拉取

docker pull chicheng/openicc:latest

7. 关闭

sudo systemctl stop docker

8. 查看所有镜像

docker images

错误

Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details

参考

若开了代理，查看当前电脑代理：

env|grep -i proxy
