用Docker搭建Nexus私服

• 搜索Nexus
• 在docker容器中加载Nexus镜像
• 发布本地项目到Nexus私服
  • 配置连接方式
  • 发布指令
  • 打源码包上传插件

搜索Nexus

  在我们打算使用Nexus时，我们先搜索一下docker景象仓库中现成的Nexus镜像。

docker search nexus

• 1

其展示的结果如下：

[root@localhost ~]# docker search nexus

  在这里，被大家使用频率越高的版本往往STARS指数越高，排位也就越靠前，这样，我们直接拉取第一个来使用就可以了。

docker pull docker.io/sonatype/nexus

  如下：

[root@localhost ~]# docker pull docker.io/sonatype/nexus

在docker容器中加载Nexus镜像

  指令如下：

docker run -d -p 8081:8081 --name nexus docker.io/sonatype/nexus

• 1

  运行结果：

[root@localhost ~]# docker run -d -p 8081:8081 --name nexus docker.io/sonatype/nexus

  在Nexus运行时，这可能需要等待一段很短的时间，我们可以通过查看Nexus的日志来了解Nexus的运行情况，其指令如下：

docker logs -f nexus

• 1

  当docker运行起来后，我们就可以在浏览器中进行访问了，访问地址为：

http://192.168.44.128:8081/nexus/#welcome

• 1

  其中192.168.44.128为虚拟机所对应的ip地址，大家在这里填写自己所在的ip地址即可。

  运行的界面如下：

  当看到这里时，这说明我们的Nexus已经正常运行，可以进行使用了。

  如果想查看与Nexus相关的更多docker镜像信息，可以到这里去查看Nexus的docker镜像官方文档。

  在这里，docker的默认账号为admin，默认密码为admin123，直接将其拿来就可以使用了。

发布本地项目到Nexus私服

配置连接方式

  配置Maven的settings.xml

    <server>
      <id>user-release</id>
      <username>admin</username>
      <password>admin123</password>
    </server>
    <server>

  发布后的结果：

打源码包上传插件

  源码包上传插件如下，将其添加到项目的pom.xml文件中即可。

<build>
    <plugins>
      <plugin> <!-- 打jar包 -->
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>3.0.1</version>
        <configuration>
          <excludes>
            <exclude>**/*.properties</exclude>
          </excludes>
        </configuration>
      </plugin>
      <plugin> <!-- 打源码 -->

        </executions>
      </plugin>
    <www.gouyiflb.cn /plugins>
  <www.caibaoyule.cn /build>

  当添加上上述插件后，当我们执行mvn deploy时，我们的项目源码包也将会一并发布到Nexus私服中
