docker nexus 及MAVEN私服搭建

一. docker

docker pull sonatype/nexus3
           

docker run -it -d  -p 8081:8081 sonatype/nexus3 -name nexus
           

若服务器内存很小, 则可以设置其内存使用大小

docker run -it -d  -p 8081:8081 -e INSTALL4J_ADD_VM_PARAMS="-Xms128m -Xmx256m -XX:MaxDirectMemorySize=256m" sonatype/nexus3 -name nexus

参数由来:

[[email protected] project]# docker inspect sonatype/nexus3

二. nexus MAVEN私服搭建

查询nexus默认密码

#进入容器
docker exec -it nexus bash

#查看默认密码
cat /nexus-data/admin.password
           

打开8081页面 -> 登录 -> 修改密码

#使用阿里云镜像仓库做上级仓库
#可自选
https://maven.aliyun.com/repository/public
           

本地settings.xml配置

到此, 就可以用mvn deploy发布jar包
