在本地创建docker的registry

参考文档：https://ken.io/note/docker-private-image-server-deploy

1. 访问在本地创建docker的registry默认是不需要输入用户名，密码的，公司内网或开发小组内部使用起来很方便，但是直接pull会报错：

$ docker pull 192.168.1.13:5000/alpine:latest

Error response from daemon: Get "https://192.168.1.13:5000/v2/": http: server gave HTTP response to HTTPS client

其中192.168.1.13:5000是之前配好的本地的registry。

解决的办法是创建/修改配置文件：

$ sudo vim /etc/docker/daemon.json

并保证daemon.json文件中有如下内容：

$ cat /etc/docker/daemon.json 
{
    "insecure-registries": [
        "192.168.1.13:5000"
    ]
}

然后重启 docker 服务

$ sudo systemctl stop docker
$ sudo systemctl start docker

再次尝试拉取Image，成功

$ docker pull 192.168.1.13:5000/alpine:latest
latest: Pulling from alpine
