默认情况下不配置加速器，我们会无法拉取镜像

配置加速器

新版本的containerd镜像仓库配置都是建议放在一个单独的文件夹当中，并且在/etc/containerd/config.toml配置文件当中打开config_path配置，指向镜像仓库配置目录即可。

这种方式只需要在第一次修改/etc/containerd/config.toml文件打开config_path配置时需要重启containerd，后续我们增加镜像仓库配置都无需重启containerd，非常方便。

root@k8s-master-01:~# cat /etc/containerd/config.toml
version = 2
root = "/var/lib/containerd"
state = "/run/containerd"
oom_score = 0

[grpc]
  address = "/run/containerd/containerd.sock"
  uid = 0
  gid = 0
  max_recv_message_size = 16777216
  max_send_message_size = 16777216

[debug]
  address = "/run/containerd/containerd-debug.sock"
  uid = 0
  gid = 0
  level = "warn"

[timeouts]
  "io.containerd.timeout.shim.cleanup" = "5s"
  "io.containerd.timeout.shim.load" = "5s"
  "io.containerd.timeout.shim.shutdown" = "3s"
  "io.containerd.timeout.task.state" = "2s"

[plugins]
  [plugins."io.containerd.grpc.v1.cri"]
    sandbox_image = "sealos.hub:5000/pause:3.9"
    max_container_log_line_size = 16384
    max_concurrent_downloads = 20
    disable_apparmor = false
    [plugins."io.containerd.grpc.v1.cri".containerd]
      snapshotter = "overlayfs"
      default_runtime_name = "runc"
      [plugins."io.containerd.grpc.v1.cri".containerd.runtimes]
        [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc]
          runtime_type = "io.containerd.runc.v2"
          [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options]
            SystemdCgroup = true
        [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.crun]
          runtime_type = "io.containerd.runc.v2"
          [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.crun.options]
            BinaryName = "/usr/bin/crun"
            SystemdCgroup = true
    [plugins."io.containerd.grpc.v1.cri".registry]
      config_path = "/etc/containerd/certs.d"
      [plugins."io.containerd.grpc.v1.cri".registry.configs]
          [plugins."io.containerd.grpc.v1.cri".registry.configs."sealos.hub:5000".auth]
            username = "admin"
            password = "passw0rd"

这里可以看到我的Containerd 已经配置config_path路径，如果没有配置请自行添加如下几行

    [plugins."io.containerd.grpc.v1.cri".registry]
      config_path = "/etc/containerd/certs.d"

配置加速器地址

Containerd配置格式如下

mkdir -p /etc/containerd/certs.d/docker.io
cat > /etc/containerd/certs.d/docker.io/hosts.toml << EOF
server = "https://docker.io"
[host."https://dockerproxy.frps.fun"]
  capabilities = ["pull", "resolve"]
EOF
