Linux替换Docker镜像源

1、创建文件夹

sudo mkdir -p /etc/docker

2、写入阿里云镜像源配置

sudo tee /etc/docker/daemon.json <<-EOF
{
"registry-mirrors": [
"https://10c3pvm2.mirror.aliyuncs.com",
"http://hub-mirror.c.163.com",
"https://mirror.baidubce.com",
"https://docker.mirrors.sjtug.sjtu.edu.cn",
"https://docker.nju.edu.cn"
]
}
EOF

3、其作用的让daemon.json配置文件重新生效

sudo systemctl daemon-reload  

4、重启docker

sudo systemctl restart docker
