解决Centos7中docker无法从非官方库中pull镜像

Linux就该这么学

系统版本

[root@bogon ~]# cat /etc/redhat-release 

CentOS Linux release 7.1.1503 (Core) 

 

docker版本

[root@bogon ~]# docker --version

Docker version 1.7.1, build 446ad9b/1.7.1

 

错误信息

[root@bogon ~]#  docker pull dl.dockerpool.com:5000/ubuntu:12.04

Error response from daemon: invalid registry endpoint https://dl.dockerpool.com:5000/v0/: unable to ping registry endpoint https://dl.dockerpool.com:5000/v0/

v2 ping attempt failed with error: Get https://dl.dockerpool.com:5000/v2/: tls: oversized record received with length 28012

 v1 ping attempt failed with error: Get https://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

[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
