查找nexus3镜像

docker search nexus

拉取nexus3镜像

docker pull docker.io/sonatype/nexus3

查看镜像

docker images

运行nexus容器

docker run -id --privileged=true --name=nexus3.4 --restart=always -p 8081:8081 -v /topcheer/nexus3/nexus-data:/nexus-data 8eb898be2a53（这个是容器id或名称）

[root@topcheer ~]# docker ps -l
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
b4d0c5712512        8eb898be2a53        "sh -c ${SONATYPE_..."   8 hours ago         Up 3 hours          0.0.0.0:8081->8081/tcp   nexus3
[root@topcheer ~]#

解释：
-id 创建守护式容器
--privileged=true 授予root权限（挂载多级目录必须为true，否则容器访问宿主机权限不足）
--name=名字给你的容器起个名字
-p 宿主机端口：容器端口映射
-v 宿主机目录：容器目录目录挂载

注意：
运行容器后访问主机+配置的宿主机映射端口无反应时，请稍等几分钟（视配置时间长短不一），等待nexus3完成初始化才能访问成功

查看仓库

在项目中配置私服

拷贝public仓库地址

技术分享图片

配置到你本地maven的settings文件
注意：是public group仓库地址而不是releases或snapshots仓库，public默认包含了这两个仓库

<profile>
        <id>dev</id>
        <repositories>
            <repository>
                <id>nexus</id>
                <url>http://nexus.topcheer.xyz:8081/nexus/content/groups/public/</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </repository>
        </repositories>
        <pluginRepositories>
            <pluginRepository>
                <id>public</id>
                <name>Public Repositories</name>
                <url>http://nexus.topcheer.xyz:8081/nexus/content/groups/public/</url>
            </pluginRepository>
        </pluginRepositories>
    </profile>


  <activeProfiles>  
      <activeProfile>dev</activeProfile>  
    </activeProfiles>

配置maven settings文件的服务器用户名密码
注意：id为私服中releases和snapshots仓库名，必须一致

<server>
      <id>docker-hub</id>
      <username>admin</username>
      <password>Harbor12345</password>
    </server>
     <server>  
        <id>maven-releases</id>  
        <username>admin</username>  
        <password>admin123</password>  
      </server>  
      <server>  
        <id>maven-snapshots</id>  
        <username>admin</username>  
        <password>admin123</password>  
      </server>

在项目父pom文件中配置部署环境，注意id及URL必须与nexus仓库对应

<distributionManagement>
        <repository>
            <id>maven-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://192.168.180.112:8081/repository/maven-releases/</url>
        </repository>
        <snapshotRepository>
            <id>maven-snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <url>http://192.168.180.112:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>
