Can't connect to mirror with "--insecure-registry http://example.com:5000".

[v11yu]

I have try to use registry mirror. Docker client is 1.7.0,and registry is 2.0. I have try to --insecure-registry http://example.com:5000 --insecure-registry example.com:5000 --insecure-registry=example.com:5000 It didn't work at all.just throw error, and you can see it in this link http://stackoverflow.com/questions/31517388/how-to-create-docker-registry-mirror-on-centos:

If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add --insecure-registry 10.11.150.75:5555 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/10.11.150.75:5555/ca.crt

Use exactly that syntax. This is a daemon flag, so you need to restart your daemon. Finally, if you use an ip, specify an ip, if you use a domain name, same thing, that needs to be consistent.

Hope that helps.
