1. 报错信息

Failed to pull image "{ip}:{port}/{project}/{image}:v1": failed to pull and unpack image "{ip}:{port}/{project}/{image}:v1": failed to resolve reference "{ip}:{port}/{project}/{image}:v1": failed to do request: Head "https://{ip}:{port}//v1": http: server gave HTTP response to HTTPS client

2. 问题分析

错误信息表明服务器使用的是HTTPS协议（即端口443或其它HTTPS默认端口之外的端口，如这里的8858），但是客户端尝试使用HTTP协议（即端口80）进行连接。这通常是因为配置错误或者URL格式不正确。

3. 解决方法

修改/etc/containerd/config.toml，在 [plugins."io.containerd.grpc.v1.cri".registry]之下
添加如下配置

		[plugins."io.containerd.grpc.v1.cri".registry.mirrors."{ip}:{port}"]
          endpoint = ["http://{ip}:{port}"]
		[plugins."io.containerd.grpc.v1.cri".registry.configs]
        [plugins."io.containerd.grpc.v1.cri".registry.configs."{ip}:{port}".tls]
          insecure_skip_verify = true

然后再重启containerd

sudo systemctl restart containerd
