新版Containerd配置镜像加速

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

   containerd config dump | grep -A 10 -B 5 "mirrors"

2. 创建镜像加速读取目录(官方推荐)

   mkdir -p /etc/containerd/certs.d/docker.io/

3. 添加镜像加速

   vi /etc/containerd/certs.d/docker.io/hosts.toml

   内容如下

   server = "https://registry-1.docker.io"
   
   [host."https://registry.cn-hangzhou.aliyuncs.com"]
     capabilities = ["pull", "resolve"]
   [host."https://mirror.ccs.tencentyun.com"]
     capabilities = ["pull", "resolve"]
   [host."https://docker.m.daocloud.io"]
     capabilities = ["pull", "resolve"]
   [host."https://swr.cn-north-4.myhuaweicloud.com"]
     capabilities = ["pull", "resolve"]

4. 重启程序

   systemctl restart containerd
