Error response from daemon: invalid registry endpointhttps://dl.dockerpool.com:5000/v0/: unable to ping registry endpointhttps://dl.dockerpool.com:5000/v0/ v2 ping attempt failed with error: Gethttps://dl.dockerpool.com:5000/v2/: tls: oversized record received with length 28012
v1 ping attempt failed with error: Gethttps://dl.dockerpool.com:5000/v1/_ping: tls: oversized record received with length 28012. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry dl.dockerpool.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/dl.dockerpool.com:5000/ca.crt

解決辦法:
修改/etc/sysconfig/docker文件,增加如下信息
OPTIONS='--selinux-enabled --insecure-registry dl.dockerpool.com:5000'
