Docker私有仓库如何实现Registry部署

小编这次要给大家分享的是Docker私有仓库如何实现Registry部署，文章内容丰富，感兴趣的小伙伴可以来了解一下，希望大家阅读完这篇文章之后能够有所收获。

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          NAMESa7773d77b8a3    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       SIZEregistry           latest       708bc6af7e5e    3 months ago    25.8MBtomcat            latest       1b6b1fe7261e    5 days ago     647MBhub.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       SIZE192.168.100.10:5000/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     Username: bob   Password:    ……………… Login Succeeded     [root@centos01 ~]# docker push 192.168.100.10:5000/image/tomcat:1.0 The push refers to repository [192.168.100.10:5000/image/tomcat]b0ac242ce8d3: Pushed5e71d8e4cd3d: Pushedeb4497d7dab7: Pushedbfbfe00b44fc: Pushedd39111fb2602: Pushed155d997ed77c: Pushed88cfc2fcd059: Pushed760e8d95cf58: Pushed7cc1c2d7e744: Pushed8c02234b8605: Pushed1.0: digest: sha256:55b41e0290d32d6888aee2e9a15f03cc88d2f49d5ad68892c54b9527d0ed181c size: 2421[root@centos02 ~]# docker pull 192.168.100.10:5000/image/tomcat:1.0  Error response from daemon: Get http://192.168.100.10:5000/v2/image/tomcat/manifests/1.0: no basic auth credentials[root@centos02 ~]# docker login 192.168.100.10:5000     Username: bob  Password:     Login Succeeded   [root@centos02 ~]# docker pull 192.168.100.10:5000/image/tomcat:1.0 1.0: Pulling from image/tomcat376057ac6fa1: Pull complete5a63a0a859d8: Pull complete496548a8c952: Pull complete2adae3950d4d: Pull complete0a297eafb9ac: Pull complete09a4142c5c9d: Pull complete9e78d9befa39: Pull complete18f492f90b9c: Pull complete7834493ec6cd: Pull complete216b2be21722: Pull completeDigest: sha256:55b41e0290d32d6888aee2e9a15f03cc88d2f49d5ad68892c54b9527d0ed181cStatus: Downloaded newer image for 192.168.100.10:5000/image/tomcat:1.0192.168.100.10:5000/image/tomcat:1.0[root@centos02 ~]# docker images  REPOSITORY             TAG         IMAGE ID      CREATED       SIZE192.168.100.10:5000/image/tomcat  1.0         1b6b1fe7261e    5 days ago     647MB192.168.100.10:5000/image/centos  6.7         b2ab0ed558bb    3 years ago     602MB
