root@gerryyang:~# docker push 104.131.173.242:5000/Ubuntu_sshd_gcc_gerry:14.04
FATA[0002] Error: Invalid registry endpoint https://104.131.173.242:5000/v1/: Get https://104.131.173.242:5000/v1/_ping: EOF. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry 104.131.173.242:5000` 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/104.131.173.242:5000/ca.crt
解决方法：
解决方案：
vi /usr/lib/systemd/system/docker.service
内容修改如下：
[Unit]
Description=Docker Application Container Engine
Documentation=http://docs.docker.com
After=network.target docker.socket
Requires=docker.socket
[Service]
Type=notify
EnvironmentFile=-/etc/sysconfig/docker
EnvironmentFile=-/etc/sysconfig/docker-storage
ExecStart=/usr/bin/docker -d --insecure-registry 10.0.0.142:5000 -H fd:// $OPTIONS $DOCKER_STORAGE_OPTIONS
LimitNOFILE=1048576
LimitNPROC=1048576
[Install]
WantedBy=multi-user.target
在CoreOS系统中，执行方法一，可能会遇到/usr/lib/systemd/system/docker.service 文件ReadOnly 无法修改的情况，这时可以手工启动并添加 --insecure-registry参数
localhost ~ # /usr/lib/coreos/dockerd --daemon --insecure-registry 10.0.0.142:5000
3 私有仓库查询方法
curl :5000/v1/search
说明：使用curl查看仓库104.131.173.242:5000中的镜像。在结果中可以查看到ubuntu_sshd_gcc_gerry，说明已经上传成功了。
4 在其他的机器上访问和下载私有仓库的镜像
在客户机上手工启动docker:localhost ~ # /usr/lib/coreos/dockerd --daemon --insecure-registry 10.0.0.142:5000
执行pull命令
localhost ~ # docker pull 10.0.0.142:5000/jdk7
