Docker搭建Nexus Maven私服

搭建nexus仓库服务器

要求

• 使用docker安装
• 支持docker、maven
• 数据持久化

安装计划

• 数据持久化：将宿主机目录/data/tools/nexus/nexus-data挂在到容器的/nexus-data目录
• nexus管理网页访问端口：8081
• nexus镜像上传下载端口：8082

下载nexus3镜像

• 搜索nexus镜像 docker search nexus

  

• 下载nexus3镜像sonatype/nexus3,该镜像使用教程

  

  root@localhost:/home$ docker volume create --name nexus-data
  

运行nexus

• 首次启动，注意data/tools/nexus/nexus-data目录权限需要修改为200:200，对应容器内部的nexus用户，不然会因权限不足导致启动失败；8081为网页端口，8082为镜像上传下载端口

  root@localhost:/home/docker/nexus$ sudo chown -R 200:200 /data/tools/docker/nexus/nexus-data/		
    
  root@localhost:/home/docker/nexus$ docker run -d -p 8081:8081 -p 8082:8082 --name nexus -v /home/docker/nexus/nexus-data:/nexus-data sonatype/nexus3

• 修改默认端口

  • 修改容器内 /nexus-data/etc/nexus.properties 文件， application-port=[your port]，这里因为和其它应用冲突，所以修改为8081。

• 测试工作是否正常

  • 命令行检测，正常运行时会输出pong

    

  • 浏览器打开http://192.168.xx.xx:8081，可正常显示网页

• 非首次启动，执行docer start nexus

附加内容可忽略

添加docker hosted仓库

• 访问http://192.168.1.56:8092，使用默认账号/密码:admin/admin123登录
• 创建docker(hosted)仓库，名称docker-hosted，注意配置http端口，这里配置为8093，与启动参数一致

修改docker启动参数

• 由于我们添加的本地仓库只配置了http服务，而docker默认使用https，因此在docker启动文件/etc/docker/daemon.json中添加私有仓库地址："insecure-registries":["http://192.168.1.56:8093"]，daemon.json文件内容变为：

    {
      "registry-mirrors": ["https://7uko0u1b.mirror.aliyuncs.com"],
      "insecure-registries":["http://192.168.1.56:8093"]
    }
  

• 重启docker服务：service docker restart

向本地仓库push镜像

• 为待上传的镜像打标签，格式为docker tag :/:

    root@localhost:/home/docker/nexus$ docker images
    REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE

• 登录仓库，默认账号/密码为：admin/admin123，不登录就push镜像会提示：no basic auth credentials

    root@localhost:/home/docker/nexus$ docker login 192.168.1.56:8093
    Username (admin): admin
    Password: 
    Login Succeeded
  

• push镜像

    root@localhost:/home/docker/nexus$ docker push 192.168.1.56:8082/hello-world:1.0
    The push refers to a repository [192.168.1.56:8093/hello-world]
    45761469c965: Layer already exists 
    1.0: digest: sha256:9fa82f24cbb11b6b80d5c88e0e10c3306707d97ff862a3018f22f9b49cef303a size: 524
  

• 从http://192.168.1.56:8092上可以看到docker-hosted仓库中已经有了刚刚上传的镜像

从本地仓库搜索镜像

	root@localhost:/home/docker/nexus$ docker search 192.168.1.56:8093/hello
	NAME                                DESCRIPTION   STARS     OFFICIAL   AUTOMATED
