Nexus私有仓库+IDEA配置远程推送

目录

一、docker安装nexus本地私服，Idea通过maven配置deploy本地jar包（简单）

二、docker push镜像到第三方nexus远程私服（shell命令操作）

三、springboot通过maven插件自动生成docker镜像并push到nexus私服（难）

---

代码有代码的管理平台，比如GitHub、GitLab、码云等。镜像也有镜像的管理平台，比如DockerHub，以及本文中的nexus。 Nexus是当前最流行的Maven仓库管理软件。本文讲解使用nexus作为docker镜像仓库。

SNAPSHOT
快照版本，在 maven 中 SNAPSHOT 版本代表正式发布（release）的版本之前的开发版本，在 pom 中用 x.y-SNAPSHOT 表示。

RELEASE
发布版本，稳定版本，在 maven 中 RELEASE 代表着稳定的版本，unchange，不可改变的，在 maven 中 SNAPSHOT 与 RELEASE 版本在策略上是完全不同的方式，SNAPSHOT 会根据你的配置不同，频繁的从远程仓库更新到本地仓库；而 RELEASE 则只会在第一次下载到本地仓库，以后则会先直接从本地仓库中寻找。

一、docker安装nexus本地私服，Idea通过maven配置deploy本地jar包（简单）

使用docker将nexus拉取到本地，启动nexus容器，即可本地访问（注意初始登录密码在容器的哪个位置）。然后在Idea中进行settings.xml文件和pom.xml文件的配置。

1. 拉取nexus镜像

docker pull sonatype/nexus3

2. 启动容器

docker run -tid -p 8081:8081 -p 8082:8082 -p 8083:8083 -p 8084:8084 --privileged=true --name nexus3 -v /docker/nexus/nexus-data:/var/nexus-data --restart=always docker.io/sonatype/nexus3

-tid  ：创建守护式容器 。
-p 8081:8081 ：宿主机端口（对外访问端口）：容器映射端口。这2个端口可不一样。浏览器访问URL用前面个端口 。8082~8084是仓库端口，如果不配置，后面访问不了
--privileged=true ：容器访问宿主机的多级目录时可能会权限不足，故给 root 权限 。
--name nexus3 ：给容器取名，可任意设定。
-v $PWD/nexus-data:/var/nexus-data ：把容器中的 nexus-data 目录挂载到宿主机当前路径下的 nexus-data 下。方便以后查看相关数据。$PWD ：取当前路径。此处可以写死为某个完整的确定的目录。 挂载格式为： -v  宿主机目录 ：容器目录 。         
--restart=always ：服务挂后，自动重启 。
docker.io/sonatype/nexus3 ：镜像名 。

3. 通过启动日志查看启动是否成功

docker logs -f nexus3

4. 本地访问并登陆（初始密码在容器的etc文件下,登录账户为admin）一定要先登录

http://ip:8081

5. 在idea的运行使用的settings文件上进行私服配置

<?xml version="1.0" encoding="UTF-8"?><settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"><localRepository>D:\software\apache-maven-3.8.1\repository</localRepository><pluginGroups></pluginGroups><proxies></proxies><servers><server><id>jy-releases</id><username>admin</username><password>admin123</password></server><server><id>jy-snapshots</id><username>admin</username><password>admin123</password></server></servers><mirrors><mirror>  <id>alimaven</id>  <name>aliyun maven</name>  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  <mirrorOf>central</mirrorOf>          </mirror></mirrors><profiles><profile><id>jy</id><activation><activeByDefault>false</activeByDefault></activation><!-- 私有库地址--><repositories><repository><id>jy</id><url>http://119.29.244.118:8081/repository/maven-public/</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository></repositories><!--插件库地址--><pluginRepositories><pluginRepository><id>jy</id><url>http://119.29.244.118:8081/repository/maven-public/</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></pluginRepository></pluginRepositories></profile><profile>    <id>jdk-1.8</id>    <activation>    <activeByDefault>true</activeByDefault>    <jdk>1.8</jdk>    </activation>    <properties>    <maven.compiler.source>1.8</maven.compiler.source>    <maven.compiler.target>1.8</maven.compiler.target>    <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>    </properties>    </profile> </profiles><!--    与上面的<profile><id>lee</id>相同--><activeProfiles><activeProfile>jy</activeProfile></activeProfiles></settings>

私服地址自己查看

为了速度更快，这里设置阿里云的镜像仓库而不是中央仓库 

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

 

6. 在项目的pom.xml文件中配置推送url地址

<distributionManagement><repository><id>jy-releases</id><url>http://119.29.244.118:8081/repository/maven-releases/</url></repository><snapshotRepository><id>jy-snapshots</id><url>http://119.29.244.118:8081/repository/maven-snapshots/</url></snapshotRepository></distributionManagement>

7. 执行命令，推送 jar 到私服

 mvn  clean  deploy -Dmaven.test.skip=true 

maven和nexus私服的简单说明

 

二、docker push镜像到第三方nexus远程私服（shell命令操作）

这里的nexus私服是公司配的，用于组内项目的jar包、镜像管理仓库。

   step1： 本地登录nexus（输入用户名和密码）

docker login 119.29.244.118:8012

说明：8081是nexus的访问地址，8012端口是在nexus上设置的推送地址,也可用于登录。

   step2：查看本地镜像（以镜像openjdk:8-jdk-alpine为例）

   step3：tag镜像

• docker tag openjdk:8-jdk-alpine 119.29.244.118:8012/ddpt/openjdk:8-jdk-alpine
  

  step4：push镜像

• docker push 119.29.244.118:8012/ddpt/openjdk:8-jdk-alpine
  

  三、springboot通过maven插件自动生成docker镜像并push到nexus私服（难）

          需求：在Springboot项目中通过maven配置+Dockerfile文件+setting文件配置，实现Springboot项目的自动打包镜像，自动推送到远程nexus私服。

step1：Dockerfile文件编写。

FROM openjdk:8-jdk-alpine
VOLUME /tmp
#把当前项目下web-app-template-1.0.0.jar 改名为web-app-template.jar添加到镜像中
ADD web-app-template-1.0.0.jar web-app-template.jar
#指定端口,最好写与项目配置的端口
EXPOSE 8081
#在镜像中运行/web-app-template.jar包,这样在运行镜像的时候就可以启动好web-app-template.jar
#-Djava.security.egd=file:/dev/./urandom 是一个启动参数的优化，用于解决应用可能（在需要大量使用随机数的情况下）启动慢的问题
#（应用的sessionID是通过该参数的配置快速产生的随机数）
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/web-app-template.jar"]

step2：settings.xml文件中配置用户名、密码和邮箱

 <server><id>docker-nexus</id><username>p****DockerUser</username><password>l****pB</password><configuration><email>liu****@***.***.com</email></configuration></server>

step3：pom.xml文件配置

  <properties><docker.repo>nexus.****.com:8012</docker.repo><docker.repository>webapptemplate</docker.repository><skipTests>true</skipTests></properties><!-- The configuration of maven-assembly-plugin --><plugin><groupId>com.spotify</groupId><artifactId>docker-maven-plugin</artifactId><version>0.4.13</version><configuration><imageName>${docker.repository}/${project.artifactId}:${project.version}_SNAPSHOT</imageName><!--指定dockerFile的路径 --><dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory><!--docker server地址 docker服务端地址，即Docker安装地址，并开启2375端口（也可以安装在本地并开启2375端口）--><dockerHost>http://10.154.7.202:2375</dockerHost><serverId>docker-nexus</serverId><registryUrl>http://nexus.cmss.com:8082/webapptemplate/</registryUrl><resources><resource><targetPath>/</targetPath><directory>${project.build.directory}</directory><include>${project.build.finalName}.jar</include></resource></resources></configuration><executions><!--绑定Docker build镜像 命令到 Maven 的package阶段--><execution><id>build-image</id><phase>package</phase><goals><goal>build</goal></goals></execution><!--绑定Docker tag镜像 命令到 Maven 的package阶段--><execution><id>tag-image</id><phase>package</phase><goals><goal>tag</goal></goals><configuration><!--镜像名称--> <image>${docker.repository}/${project.artifactId}:${project.version}_SNAPSHOT</image><!--镜像Tag名称--> <newName>${docker.repo}/${docker.repository}/${project.artifactId}:${project.version}_SNAPSHOT</newName><forceTags>true</forceTags></configuration></execution><!--绑定Docker push镜像 命令到 Maven 的package阶段--><execution><id>push-image</id><phase>package</phase><goals><goal>push</goal></goals><configuration><imageName>${docker.repo}/${docker.repository}/${project.artifactId}:${project.version}_SNAPSHOT</imageName></configuration></execution></executions></plugin>

step4：打包并自动推送镜像

mvn clean deploy -Dmaven.test.skip=true
