# /etc/containerd/config.toml
[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
  [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
    endpoint = ["https://gh-proxy.cn"]

sudo systemctl restart containerd
sudo crictl pull alpine:latest

新版 containerd 的 certs.d 写法：

# /etc/containerd/certs.d/docker.io/hosts.toml
server = "https://gh-proxy.cn"

[host."https://gh-proxy.cn"]
  capabilities = ["pull", "resolve"]
