docker-k8s-web: Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
经过分析发现是 drone 所在的服务器下载镜像会存在超时，手动进行拉取测试解决这个问题。
第二个问题遇到的是：
1
Error response from daemon: Get "https://10.7.*.*/v2/": Get "https://www.harbor.mobi/service/token?account=******&client_id=docker&offline_token=true&service=harbor-registry": dial tcp: lookup www.harbor.mob2i on 127.0.0.11:53: read udp 127.0.0.1:49741->127.0.0.11:53: i/o timeout
