从 registry 启动私有(private) docker 注册表后docker 镜像，登录注册表

docker login http://docker.mydomain.com:5000

FATA[0007] Error response from daemon: v1 ping attempt failed with error: Get https://docker.mydomain.com:5000/v1/_ping: dial tcp: lookup docker.mydomain.com: no such host. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry docker.mydomain.com:5000` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/docker.mydomain.com:5000/ca.crt 

docker login --insecure-registry http://docker.mydomain.com:5000

最佳答案

你误会了--insecure-registry flag - 这是给你的守护进程而不是你的客户端。如错误消息中所述:

please add --insecure-registry docker.mydomain.com:5000 to the daemon's arguments.
