# Centos网络源安装Containerd

1. 设置存储库

   [阿里源配置文件](https://developer.aliyun.com/mirror/docker-ce?spm=a2c6h.13651102.0.0.4eac1b11shXBpr)

   ```bash
   yum install -y yum-utils
   yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
   ```

   > 国内
   >
   > ```bash
   > yum install -y yum-utils
   > yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
   > ```

2. 安装

   ```bash
   yum install -y containerd.io
   ```

3. 备份配置文件并使用默认配置文件

   ```bash
   mv /etc/containerd/config.toml /etc/containerd/config.toml.bak
   containerd config default > /etc/containerd/config.toml
   ```

4. 修改驱动和镜像地址

   ```bash
   vi /etc/containerd/config.toml
   ```

   内容如下(已更新为最新版配置方法，旧版层级不同)

   ```toml
   [plugins]
     ...
     [plugins.'io.containerd.cri.v1.runtime'.containerd.runtimes.runc.options]
       SystemdCgroup = true # 修改这里用于配置容器运行时使用 systemd 作为 cgroup 驱动 的关键设置
   
   [plugins.'io.containerd.cri.v1.images'.pinned_images]
     sandbox = 'registry.aliyuncs.com/google_containers/pause:3.10.1'
   ```

5. 启动

   ```bash
   systemctl enable containerd
   systemctl start containerd
   systemctl status containerd
   ```

6. 验证

   ```bash
   ctr info
   ```
