- Docker镜像+Nexus私有仓库+IDEA配置远程推送
- 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。
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。
- step1:查找nexus
docker search nexus
- step2:拉取nexus镜像
docker pull sonatype/nexus3
- step3:启动容器
docker run -tid -p 8081:8081 --privileged=true --name nexus3 -v $PWD/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 。
--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 。
- step4:通过启动日志查看启动是否成功
docker logs -f nexus3
- step5: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)
http://localhost:8081 - step6:在idea的运行使用的settings文件上进行私服配置
- step7:在项目的pom.xml文件中配置推送url地址
- step8:执行命令,推送 jar 到私服
mvn clean deploy -Dmaven.test.skip=true
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。
nexus远程私服地址:http://nexus.***.com:8081/ 用户名:…/登陆密码:…
- step1:本地登录nexus(输入用户名和密码)
docker login nexus.***.com: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 nexus.***.com:8012/ddpt/openjdk:8-jdk-alpine
- step4:push镜像
docker push nexus.***.com: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>

- step4:打包并自动推送镜像
mvn clean deploy -Dmaven.test.skip=true
