docker的私有仓库

创建一个自己的私有仓库，存放自己的镜像

一：构建registry私有仓库

#安装registry仓库
[[email protected]_0_7_centos ~]# docker image pull registry
[[email protected]_0_7_centos ~]# docker run --name my_registry -d -p 5001:5000 registry
#测试（下载一个nginx镜像）
[[email protected]_0_7_centos ~]# docker pull nginx
[[email protected]_0_7_centos ~]# docker tag nginx 139.199.25.216:5001/nginx:test
[[email protected]_0_7_centos ~]# docker images |grep nginx
139.199.25.216:5001/nginx   test                dbfc48660aeb        2 weeks ago         109MB
#上传
[[email protected]_0_7_centos ~]# docker push 139.199.25.216:5001/nginx:test
The push refers to a repository [139.199.25.216:5001/nginx]
Get https://139.199.25.216:5001/v2/: http: server gave HTTP response to HTTPS client
注意：自1.13版本后，默认使用的是https，但是搭建的是http，做如下修改
[[email protected]_0_7_centos ~]# cat /etc/docker/daemon.json 
{
 #加速器
 "registry-mirrors": ["https://registry.docker-cn.com"],
 "insecure-registries":["139.199.25.216:5001"]
}
#重启容器和docker服务
[[email protected]_0_7_centos ~]# systemctl restart docker
[[email protected]_0_7_centos ~]# docker start my_registry
#重新上传
[[email protected]_0_7_centos ~]# docker push 139.199.25.216:5001/nginx:test

二：查看私有仓库中有哪些镜像

1：shell版

[[email protected]_0_7_centos ~]# cat registry_image.sh 
#!/bin/bash
#Author: heitao
#date:2018/11/1

find() {
  if [ $# -ne 1 ];then
     echo "Usage:$0 [Host:port]"
     exit 250
  fi
  
  #获取镜像的名字
  name=`curl -s -XGET http://$1/v2/_catalog`
  
  echo "registry有如下镜像:"
  #根据镜像名字获取标签
  for image in `echo $name|grep -o '\[.*\]'|grep -o '\".*\"'|sed 's/,/\n/g;s/"//g'`
  do
      tag=`curl -s -XGET http://$1/v2/${image}/tags/list`
      echo $tag|awk -F'"' '{print $4":"$8}'
  done
}

find $1

2：python版

[[email protected]_0_7_centos ~]# cat registry_image.py 
#!/usr/bin/env python
#coding:utf-8
#查看私有仓库(registry)中有哪些镜像
 
import commands,sys
import json
 
def find():
    #获取镜像名字字典
    url='curl -s -XGET http://%s/v2/_catalog' %sys.argv[1]
    name_str=commands.getoutput(url)
    name_dict=json.loads(name_str)
 
    name_list=name_dict.values()
    for i in name_list[0]:
        url='curl -s -XGET http://%s/v2/%s/tags/list' %(sys.argv[1],i)
        tag=json.loads(commands.getoutput(url))
        tag_tup=tag.values()[0].encode('utf-8'),tag.values()[1][0].encode('utf-8')
        print(tag_tup[0]+":"+tag_tup[1])
 
if __name__ == "__main__":
    if len(sys.argv) != 2:
        sys.exit("Usage:%s [Host:port]"%sys.argv[0])
    else:
        find()

以上就是自己的私有仓库，后期所有的镜像都上传到这里
