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 [root@bogon ~]# 解决办法： 修改/etc/sysconfig/docker文件，增加如下信息 OPTIONS='--selinux-enabled --insecure-registry dl.dockerpool.com:5000' 重启docker服务并重新下载 [root@bogon ~]# systemctl restart docker.service [root@bogon ~]# docker pull dl.dockerpool.com:5000/ubuntu:12.04 Trying to pull repository dl.dockerpool.com:5000/ubuntu ... 0b310e6bf058: Download complete 511136ea3c5a: Download complete 5f18d94c3eca: Download complete 53db23c604fd: Download complete 9f045ea36057: Download complete d03a1a9d7555: Download complete 30868777f275: Download complete Status: Downloaded newer image for dl.dockerpool.com:5000/ubuntu:12.04 (责任编辑：IT) |
