+
+[Public-Image-Mirror](https://github.com/DaoCloud/public-image-mirror)
+
+> 本文适用于 Containerd v2.2.0 版本添加镜像加速(备注：各版本添加镜像加速参数具有差异请对照好版本)
+>
+> 查看 Containerd 版本 `containerd --version`
+
+1. 查看是否存在镜像加速
+
+   ```bash
+   containerd config dump | grep -A 10 -B 5 "mirrors"
+   ```
+
+2. 检查 Containerd 配置
+
+   ```bash
+   cat /etc/containerd/config.toml
+   ```
+
+   保证有如下内容
+
+   ```toml
+   [plugins]
+     [plugins."io.containerd.grpc.v1.cri"]
+       ...
+       [plugins."io.containerd.grpc.v1.cri".registry]
+         config_path = "/etc/containerd/certs.d"
+   ```
+
+3. 创建镜像加速读取目录
+
+   ```bash
+   mkdir -p /etc/containerd/certs.d
+   ```
+
+4. 添加镜像加速
+
+   > 目录名称为需要加速的镜像官方地址
+
+   - docker.io
+
+     创建目录
+
+     ```bash
+     mkdir -p /etc/containerd/certs.d/docker.io
+     ```
+
+     内容如下
+
+     ```toml
+     cat > /etc/containerd/certs.d/docker.io/hosts.toml <<EOF
+     server = "https://registry-1.docker.io"
+     
+     [host."https://docker.m.daocloud.io"]
+       capabilities = ["pull", "resolve"]
+     [host."https://docker.1ms.run"]
+       capabilities = ["pull", "resolve"]
+     [host."https://docker-0.unsee.tech"]
+       capabilities = ["pull", "resolve"]
+     [host."https://registry-1.docker.io"]
+       capabilities = ["pull", "resolve"]
+     EOF
+     ```
+
+   - quay.io
+
+     创建目录
+
+     ```bash
+     mkdir -p /etc/containerd/certs.d/quay.io
+     ```
+
+     内容如下
+
+     ```toml
+     cat > /etc/containerd/certs.d/docker.io/hosts.toml <<EOF
+     server = "https://quay.io"
+     
+     [host."https://docker.m.daocloud.io"]
+       capabilities = ["pull", "resolve"]
+     EOF
+     ```
+
+   - 其他
+
+     ......(内容如上)
+
+5. 此配置无需重启 Containerd
+
+6. 查看是否启用了代理
+
+   ```bash
+   ctr --debug=true i pull --hosts-dir=/etc/containerd/certs.d docker.io/nginx:latest
+   ```
