系统环境：Centos7、jdk1.8

docker私服：可以把项目通过dockerfile文件build成docker镜像，供其他环境拉取。部署在本地，私有化。

安装

dockerHUB私服

1. 搭建registry

 #拉取registry镜像

a. 运行错误1

错误提示: [root@izj6c0zsm04q86s2tu4e12z /]# docker run -it docker.io/ubuntu:latest /bin/bash
/usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:235: starting container process caused "process_linux.go:258: applying cgroup configuration for process caused \"Cannot set property TasksAccounting, or unknown property.\"".

解决办法: yum update

b. 私有仓库push错误(改配置后一定要重启docker)

docker私有仓库的5000端口是否在防火墙中打开
daemon.json文件中提交镜像的地址是否修改为私有docker仓库的地址
添加镜像仓库地址insecure-registries参数，内容修改如下：

vim /etc/docker/daemon.json
{
    "registry-mirrors":["https://registry.docker-cn.com"],
     "insecure-registries":["47.240.32.247:5000"]
}

[root@localhost bin]# systemctl daemon-reload
[root@localhost bin]# systemctl restart docker
