Docker-安装私服

Posted 2021-06-28 guardwhy

在使用maven管理jar包依赖的时候，为了避免每次都从中央仓库拉取依赖包，使用了nexus做了代理仓库。docker镜像仓库与nexus私服仓库作用类似，用于将打包好的镜像保存在仓库中方便开发、测试、生产环境镜像拉取存储，减轻环境部署需要的相应操作。

1.1 购买阿里云服务器

1、选择云服务器，创建实例

2、自定义购买，按量付费

3、选择服务器类型，数量，内存，带宽



4、自定义登录密码

5、创建成功！！！

1.2 节点信息

购买两个服务器，服务器的名字为root，服务器密码: Hxy162530。

主机名	ip地址	具体说明
guardwhy01	8.134.117.200	docker主机
guardwhy02	8.134.113.78	registry主机

1.3 官方私服

1、镜像官方地址: https://hub.docker.com/_/registry

2、基础镜像

拉取基本镜像

docker pull registry:2.7.1

运行容器

docker run -itd --name gegistry -p 5000:5000 --restart always registry:2.7.1

访问链接: http://8.134.113.78:5000/v2/_catalog

3、添加私服仓库地址

编辑配置文件
vim /etc/docker/daemon.json

增加仓库配置信息
{ "insecure-registries":["8.134.113.78:5000"] }

重启docker
systemctl daemon-reload
systemctl restart docker

查看docker信息确认仓库是否添加
docker info

4、上传镜像

docker tag nginx:1.20.1 8.134.113.78:5000/nginx:v1
docker push 8.134.113.78:5000/nginx:v1

5、查看镜像版本和信息

6、从官方私服中下载镜像

[root@guardwhy01 ~]# docker images
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE
[root@guardwhy01 ~]# docker pull 8.134.113.78:5000/nginx:v1

[root@guardwhy01 ~]# 

1.4 企业私服

1.4.1 安装私服

1、购买2核8G内存服务器，安装docker和docker compose

2、下载harbor

官方地址: https://goharbor.io/

github官网地址：https://github.com/goharbor/harbor

官方帮助文档：https://github.com/goharbor/harbor/blob/v1.9.4/docs/installation_guide.md

3、服务器配置

硬件资源	最小配置	推荐配置
CPU	2CPU	4CPU
内存	4GB	8GB
硬盘	40GB	60GB

4、安装harbor开发环境大部分采用http方式进行安装，推荐使用离线安装！！！

通过Xftp上传到\\home\\data目录中，然后解压软件。

[root@guardwhy03 data]# ls
harbor-offline-installer-v1.9.4.tgz
[root@guardwhy03 data]# tar zxvf harbor-offline-installer-v1.9.4.tgz 
harbor/harbor.v1.9.4.tar.gz
harbor/prepare
harbor/LICENSE
harbor/install.sh
harbor/harbor.yml
[root@guardwhy03 data]# ll
total 624500
drwxr-xr-x 2 root root      4096 Jun 17 21:53 harbor
-rw-r--r-- 1 root root 639477963 Jun 17 21:11 harbor-offline-installer-v1.9.4.tgz

5、进入安装目录，修改harbor.yml文件

修改私服镜像地址

hostname: 8.134.123.77

修改镜像地址访问端口号

port: 5000

harbor管理员登录系统密码

harbor_admin_password: Harbor12345

修改harbor映射卷目录

data_volume: /home/data/harbor

​
5、安装harbor

执行启动脚本

./install.sh

准备安装环境：检查docker版本和docker-compose版本
​
安装成功！！！

6、使用Chrome 浏览器访问harbor私服，点击链接: http://8.134.123.77:5000/harbor/projects，输入用户名和默认的密码

1.4.2 上传镜像

1、在主机docker01中配置私服。

[root@guardwhy01 data]# vim /etc/docker/daemon.json
[root@guardwhy01 data]# cat /etc/docker/daemon.json
{
  "registry-mirrors": ["https://5bsomu6l.mirror.aliyuncs.com"],
  "insecure-registries":["8.134.123.77:5000"]
}
## 重启docker服务！！！
[root@guardwhy01 data]# systemctl daemon-reload
[root@guardwhy01 data]# systemctl restart docker

2、在harbor界面中新建项目：guardwhy_cms

3、登录和退出私服

## 登录私服
docker login -u admin -p Harbor12345 8.134.123.77:5000

## 退出私服
docker logout 8.134.123.77:5000

查看当前镜像

[root@guardwhy01 data]# docker images
REPOSITORY   TAG                  IMAGE ID       CREATED       SIZE
nginx        1.20.1               993ef3592f66   3 weeks ago   133MB
tomcat       9.0.20-jre8-alpine   387f9d021d3a   2 years ago   108MB

4、上传镜像

docker tag nginx:1.20.1 8.134.123.77:5000/guardwhy_cms/nginx:v1.0
docker tag tomcat:9.0.20-jre8-alpine 8.134.123.77:5000/guardwhy_cms/tomcat:v1.0

## 推送操作
docker push 8.134.123.77:5000/guardwhy_cms/nginx:v1.0
docker push 8.134.123.77:5000/guardwhy_cms/tomcat:v1.0

查看镜像

上传镜像成功！！

5、通过私服下载镜像，下载成功！！！
