containerd 使用镜像加速站的问题

在 cf 做了一个镜像加速站，docker.dockerimage.site ，然后 docker pull 完全没问题，rancher 要使用 containerd,但是 containerd 会有问题。首先 containerd 需要配置镜像加速站信息，在/etc/containerd/config.toml 增加

[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
  [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
    endpoint = ["https://docker.dockerimage.site"]

然后可以用下列命令拉镜像，但是总是拉不成功，后来发现是卡在它仍然要去 auth.docker.io 获取 token 才行

# ctr images pull docker.dockerimage.site/library/busybox:latest --http-dump

镜像加速站用的是这个 https://github.com/ciiiii/cloudflare-docker-proxy 在 cf 上创建的，看到有人提了一个类似的 issue https://github.com/ciiiii/cloudflare-docker-proxy/issues/79 。不知道是否有解决方案。

可能是版本配置问题，有两种配置方式
这是我目前使用的

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

#/etc/containerd/certs.d/
#└── docker.io/
# ├── ca.crt # CA 证书
# ├── client.cert # 客户端证书（如果需要）
# ├── client.key # 客户端密钥（如果需要）
# └── hosts.toml # Harbor 映射配置文件
#/etc/containerd/certs.d/docker.io/hosts.toml
# docker 为代理 project 名称
server = "https://harbor.xxxxxxxxx.cn"

[host."https://harbor.xxxxxx.cn/v2/docker"]
capabilities = ["pull","resolve"]
override_path = true
[host."https://harbor.xxxxxxx.cn".header]
Authorization = ["Basic <password-base64>"]

@evill 这个不影响啊，无非就是配置 registry ，你这个是私有的，估计不会认证 auth.docker.io ，我这个只是相当于代理。

镜像代理服务器问题，它只是个代理，不是 registry mirror ，你无法解决，除非服务端帮你完成验证 token

这个服务端直接透传给你，没有帮你跳过取得 token 步骤
```
Www-Authenticate: Bearer realm="https://auth.docker.io/token",service="registry.docker.io",scope="repository:library/busybox:pull"
```

@hongyexiaoqing 所以我想看看有没有别的镜像加速器的方案，目前搜到最简单的是这个，docker pull 没问题，containerd 就有问题，所以应该还有别的解决方案。

@xuyan1994 你这个原理和我一样，docker pull 没有问题，containerd 不行。我走代理的方案了。

https://github.com/cmliu/CF-Workers-docker.io/blob/main/_worker.js 换了这个 worker ，支持 containerd 了。

加个代理直接拉吧，有的镜像站镜像不全，还有的镜像不在白名单内拉不了.

我现在用的 sniproxy + hosts 解决
192.168.1.11 是运行 sniproxy 的主机

192.168.1.11 docker.io
192.168.1.11 auth.docker.io
192.168.1.11 registry-1.docker.io
192.168.1.11 production.cloudflare.docker.com
