【Docker Nexus3】maven 私库

1.部署环境

• window 11 x64
• Docker Desktop 4.34.1 (166053)
  • Docker Engine v27.2.0

1.1.Docker 镜像源

1.1.1.Docker Engine 配置

{
  "builder": {
    "features": {
      "buildkit": true
    },
    "gc": {
      "defaultKeepStorage": "32GB",
      "enabled": true
    }
  },
  "experimental": true, 
  "hosts": [
    "tcp://0.0.0.0:2375"
  ],
  "registry-mirrors": [
    "https://docker.mirrors.ustc.edu.cn",
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "https://mirror.ccs.tencentyun.com"
  ]
}

2.拉取Nexus3镜像

# 拉取镜像
docker pull sonatype/nexus3
# 保存镜像源（选）
docker save -o sonatype_nexus3_latest sonatype/nexus3:latest

3.创建并运行Nexus3

# 创建运行镜像，设置最大内存
docker run -itd -p 18081:8081 -p 18082:8082 -p 18083:8083 --privileged=true --name nexus3 -v D:\docker\maven\nexus\data:/var/nexus-data -v D:\docker\maven\nexus\nexus-data:/nexus-data -e INSTALL4J_ADD_VM_PARAMS="-Xms512m -Xmx2048m -XX:MaxDirectMemorySize=2048m -Djava.util.prefs.userRoot=/nexus-data/javaprefs" --restart=always docker.io/sonatype/nexus3

说明

• 内存限制 -e INSTALL4J_ADD_VM_PARAMS="-Xms512m -Xmx2048m -XX:MaxDirectMemorySize=2048m -Djava.util.prefs.userRoot=/nexus-data/javaprefs"
• --privileged=true 允许容器使用管理员权限
• --restart=always 自动重启

3.1.访问及查看密码

查看初始登录密码

docker exec -it nexus3 /bin/bash
cat /opt/sonatype/sonatype-work/nexus3/admin.password

修改登录默认密码

访问 http://127.0.0.1:18081/

3.2.创建存储

3.3.创建代理库

参考私库镜像

• aliyun：https://maven.aliyun.com/repository/public
• nexus-aliyun：http://maven.aliyun.com/nexus/content/groups/public
• jeecg：https://maven.jeecg.org/nexus/content/repositories/jeecg
• jeecg-snapshots：https://oss.sonatype.org/content/repositories/snapshots

3.4.创建本地库

3.5.将创建的私库，添加到公共库中

4.配置 maven

可以访问公共库

settings.xml

          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <mirrors>
      <mirror>
          <id>maven-public</id>
          <mirrorOf>maven-public</mirrorOf>
          <name>maven-public</name>
          <url>http://xxx.xxx.xxx.xxx:18081/repository/maven-public/</url>
      </mirror>
  </mirrors>

  <profiles></profiles>
</settings>

5.配置pom.xml

发布配置

 <distributionManagement>
        <repository>
            <id>xxx-center</id>
            <name>xxx-center</name>
            <url>http://xxx.xxx.xxx.xxx:18081/repository/djb-center/</url>
        </repository>
        <snapshotRepository>
            <id>djb-center-snapshot</id>
            <name>djb-center-snapshot</name>
            <url>http://xxx.xxx.xxx.xxx:18081/repository/djb-center-snapshot/</url>
        </snapshotRepository>
    </distributionManagement>

拉取镜像配置

<repositories>
		<repository>
			<id>maven-public</id>
			<name>maven-public</name>
			<url>http://xxx.xxx.xxx.xxx:18081/repository/xxx-center/</url>
		</repository>
	</repositories>

也可以指定源配置(不推荐)

<repositories>
        <repository>
            <id>aliyun</id>
            <name>aliyun Repository</name>
            <url>https://maven.aliyun.com/repository/public</url>
            <snapshots>
				<enabled>false</enabled>
			</snapshots>
        </repository>
		<repository>
            <id>jeecg</id>
            <name>jeecg Repository</name>
            <url>https://maven.jeecg.org/nexus/content/repositories/jeecg</url>
            <snapshots>
				<enabled>false</enabled>
			</snapshots>
		</repository>
		<repository>
			<id>jeecg-snapshots</id>
			<name>jeecg-snapshots Repository</name>
			<url>https://oss.sonatype.org/content/repositories/snapshots</url>
			<releases>
				<enabled>false</enabled>
			</releases>

				<enabled>true</enabled>
			</snapshots>
		</repository>
</repositories>
