使用Docker搭建本地Nexus私有仓库

0-1开始Java语言编程之路

一、Ubuntu下Java语言环境搭建

二、Ubuntu下Docker环境安装

三、使用Docker搭建本地Nexus Maven私有仓库

四、Ubuntu下使用VisualStudioCode进行Java开发

你需要Nexus

Java应用编译构建的一种主流方式就是通过Maven, Maven可以很方便的管理Java应用的各种依赖包。但是在默认情况下，maven在进行java应用编译的时候，会从maven远程仓库下载相应的依赖包。Maven公共仓库是在国外的，网络不好的情况下，依赖包的下载会相当的耗时，这时私有库就派上了用场。

通过Docker 快速搭建Nexus私有仓库

Nexus是一款开源的私有仓库，他们也提供了官方的docker镜像，使用docker部署起来非常的方便，不过也有一些小细节需要我们注意，下面我们一步一步来搭建这个本地私用库吧。

拉取最新Nexus镜像

docker pull sonatype/nexus3

docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

prom/prometheus-linux-amd64 latest 051cb67876a6 6 days ago 262MB

apache/apisix 3.9.0-debian 5e90db4294cd 2 weeks ago 326MB

sonatype/nexus3 latest b630de26992b 4 months ago 570MB

hello-world latest d2c94e258dcb 11 months ago 13.3kB

bitnami/etcd 3.5.7 985a23c47893 12 months ago 146MB

我们可以看到 sonatype/nexus3这个镜像，570MB大小，所以下载的时候，需要一些时间，请大家耐心等待。

创建nexus数据卷

Nexus需要从远程仓库同步依赖库，所以需要持久化存储这些依赖库到本地，因此我们需要选创建一个数据卷。

另外，在Nexus第一次启动时，会在数据卷中创建初始密码文件，我们需要查看该文件，获得初始密码我们才能进行进一步的Nexus初始化工作。

#创建一个名为 nexus-data的数据卷

docker volume create --name nexus3

#查看数据卷信息

docker volume inspect nexus3

root@txzq1899-ubuntu:/var/lib/docker/volumes/nexus3/_data#

这里要注意docker默认将数据卷存放在

/var/lib/docker/volumes 目录，而这个目录需要root权限才能访问。

创建并运行Nexus容器

–name nexus3

指定容器名称为 nexus3 -e NEXUS_CONTEXT=nexus

指定访问上下文，即通过http://localhost:8081/nexus访问 INSTALL4J_ADD_VM_PARAMS

调整JVM参数 -v nexus3:/nexus-data

映射数据卷

docker run -d -p 8081:8081 \

--name nexus3 -e NEXUS_CONTEXT=nexus \

-e INSTALL4J_ADD_VM_PARAMS="-Xms1024m -Xmx1024m -XX:MaxDirectMemorySize=1024m" \

-v nexus3:/nexus-data \

sonatype/nexus3

查看容器日志

#Nexus 初次启动会比较慢，我们可以查看nexus3的容器日志。

#当我们看到 Started Sonatype Nexus OSS 3.63.0-01

#就表示Nexus 已经启动成功了。

docker logs -f nexus3

访问Nexus

先打开admin.password文件，复制初始密码

打开本地Nexus:

Local Nexus3

第一次登录Nexus

第一次登录后，会提示修改管理员密码

配置阿里云代理

进到Repository设置页面，点Create Rrepository,

Repository 管理

这里我们选择《maven2 proxy》

选择maven2 proxy

输入Name : aliyunProxy 设置，输入Remote storage :

http://maven.aliyun.com/nexus/content/groups/public

保存配置

在这里插入图片描述

配置maven-public(group)

回到Repository管理页面，找到maven-public，并点击 maven-public进入编辑页面

在Member repositories 左则 Available List中的aliyun 添加右则的 Members中，并将aliyun 上移至第一的位置。点Save进行保存

在这里插入图片描述

测试验证

到这里本地的Nexus 私有库就已经基本上搭建好了。

在使用之前，首先要在maven的配置文件中使用我们本地的私有仓库

通常在~/.m2/目录下，有一个 setting.xml 文件，如果没有，请创建。

<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"

我们通过Visual Studio Code 创建一个SpringBoot 项目，并找开该项目。

在这里插入图片描述

打开一个终端，通过Maven进行一次编译

mvn clean install

查看编译过程，我们可以看到在repackage阶段，已经从本地nexus下载依赖包了。
