Docker私有仓库Registry部署的实现

随着docker使用的镜像越来越多，就需要有一个保存镜像的地方，这就是仓库。目前常用的两种仓库：公共仓库和私有仓库。最方便的就是使用公共仓库上传和下载，下载公共仓库的镜像是不需要注册的，但是上传时，是需要注册的。

私有仓库最常用的就是Registry、Harbor两种，那接下来详细介绍如何搭建registry私有仓库，Harbor将在下一篇博文部署。

一、部署Registry私有仓库

案例描述

两台CentOS7.4，一台为Docker私有仓库；另一台为Docker客户端，测试使用；

两台服务器都需要安装Docker服务，请参考博文：安装Docker.v19版本

1、配置registry私有仓库

[root@centos01 ~]# echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf  
    
[root@centos01 ~]# sysctl -p  
net.ipv4.ip_forward = 1
[root@centos01 ~]# vim /etc/docker/daemon.json  
{"registry-mirrors":["https://6kx4zyno.mirror.aliyuncs.com"]}  
[root@centos01 ~]# systemctl reload docker 
[root@centos01 ~]# docker search registry 

[root@centos01 ~]# docker run -d -p 5000:5000 --name registry --restart=always -v /opt/registry:/var/lib/registry registry
 
 
[root@centos01 ~]# docker ps  
CONTAINER ID    IMAGE        COMMAND         CREATED       STATUS       PORTS          NAMES
a7773d77b8a3    registry      "/entrypoint.sh /etc…"  50 seconds ago   Up 46 seconds    0.0.0.0:5000->5000/tcp  registry
[root@centos01 ~]# docker images  
REPOSITORY          TAG         IMAGE ID      CREATED       SIZE
registry           latest       708bc6af7e5e    3 months ago    25.8MB
tomcat            latest       1b6b1fe7261e    5 days ago     647MB
hub.c.163.com/public/centos  6.7-tools      b2ab0ed558bb    3 years ago     602MB
[root@centos01 ~]# vim /etc/docker/daemon.json 
{"registry-mirrors":["https://6kx4zyno.mirror.aliyuncs.com"],
"insecure-registries":["192.168.100.10:5000"]  
}
[root@centos01 ~]# systemctl reload docker  

2、上传镜像到registry私有仓库

[root@centos01 ~]# docker tag hub.c.163.com/public/centos:6.7-tools 192.168.100.10:5000/image/centos:6.7  
    
[root@centos01 ~]# docker push 192.168.100.10:5000/image/centos:6.7 

二、配置Docker客户端访问私有仓库

[root@centos02 ~]# vim /etc/docker/daemon.json  
{"registry-mirrors":["https://6kx4zyno.mirror.aliyuncs.com"],
"insecure-registries":["192.168.100.10:5000"]  
}
[root@centos02 ~]# systemctl restart docker  
[root@centos02 ~]# docker pull 192.168.100.10:5000/image/centos:6.7 
         
[root@centos02 ~]# docker images 
REPOSITORY             TAG         IMAGE ID      CREATED       SIZE
192.168.100.10:5000/image/centos  6.7         b2ab0ed558bb    3 years ago     602MB

至此registry私有仓库已经搭建完成，但是现在存在一个问题，如果这也部署的话企业内部所有人员皆可访问我们的私有仓库，为了安全起见，接下来为registry添加一个身份验证，只有通过了身份验证才可以上传或者下载私有仓库中的镜像。

三、配置registry加载身份验证

[root@centos01 ~]# yum -y install httpd-tools  
[root@centos01 ~]# mkdir /opt/registry-auth 
[root@centos01 ~]# htpasswd -Bbn bob pwd@123 > /opt/registry-auth/htpasswd
 



[root@centos01 ~]# docker run -d -p 5000:5000 --restart=always \
-v /opt/registry-auth/:/auth/ \
-v /opt/registry:/var/lib/registry --name registry-auth -e "REGISTRY_AUTH=htpasswd" \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-e "REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd" registry 
 
[root@centos01 ~]# docker tag tomcat:latest 192.168.100.10:5000/image/tomcat:1.0 
    
[root@centos01 ~]# docker push 192.168.100.10:5000/image/tomcat:1.0 

no basic auth credentials

[root@centos01 ~]# docker login 192.168.100.10:5000

Password:
