【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

<?xml version="1.0" encoding="UTF-8"?><settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd"><localRepository>D:\workspace\env\repository</localRepository><pluginGroups></pluginGroups><proxies></proxies><servers><server><id>xxx-center</id><username>admin</username><password>xxxxxx</password></server><server><id>xxx-center-snapshot</id><username>admin</username><password>xxxxxx</password></server></servers><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><snapshots><enabled>true</enabled></snapshots></repository>
</repositories>

6.打包与发布

# 打包
mvn -Dfile.encoding=UTF-8 -DskipTests=true clean package -P prod
# 发布
