docker registry的https錯誤解決

從docker1.3.2版本開始默認docker registry使用的是https，當你用docker pull 非https的docker regsitry的時候會報下面錯誤：

Error: Invalid registry endpoint ... Get ... If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add '--insecure-registry 192.168.1.103:5000' 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/192.168.1.103:5000/ca.crt

 

解決方案：

vi /usr/lib/systemd/system/docker.service

 

內容修改如下：
