# 配置国内的镜像源

## 阿里云镜像加速
在阿里云官网的帮助文档里搜索一下镜像加速
通过修改 daemon 配置文件 /etc/docker/daemon.json 来使用加速器
```sh
sudo mkdir -p /etc/docker
```
括号内替换为你自己的镜像源就可以了
```sh
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://frcxiu9f.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
```

## 使用腾讯云镜像
同样的步骤
```
vim /etc/docker/daemon.json
```
腾讯云的镜像源
```
{
   "registry-mirrors": [
       "https://mirror.ccs.tencentyun.com"
  ]
}
```

使用任意一个，保存退出，重载配置文件
```sh
systemctl daemon-reload
```
重启Docker
```sh
systemctl restart docker
```
