# 镜像加速


以阿里云的centos为例,在阿里云的容器镜像服务中找到镜像加速链接  
以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
```shell
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://58lzdfe1.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
```
