skopeo inspect does not work behind proxy

问题

I am facing this while installing OKD 3.11.

While the docker login works from command line, skopeo fail to do so. We are using http/https proxy on the server and have configured proxy for docker as well.

[root@hostname-ansible01 openshift-ansible]# docker login registry.redhat.io:443 -u user_openshift -p password

Login Succeeded

[root@hostname-ansible01 openshift-ansible]# skopeo inspect --creds=user_openshift:password docker://registry.redhat.io:443/openshift3/ose-deployer:v3.11

FATA[0000] pinging docker registry returned: Get https://registry.redhat.io:443/v2/: proxyconnect tcp: EOF```
