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 --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 。
--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)
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"><!-- 本地仓库地址 --><localRepository>D:\mvn_repo\repository</localRepository><!-- 以下配置为上传jar包配置 --><pluginGroups></pluginGroups><proxies></proxies><servers><server><!-- id,对应项目里面pom.xml里面distributionManagement配置的id --><id>maven-releases</id><!-- 登录nexus的用户名 --><username>admin</username><!-- 登录nexus的密码 --><password>admin123</password></server><server><!-- id,对应项目里面pom.xml里面distributionManagement配置的id --><id>maven-snapshots</id><!-- 登录nexus的用户名 --><username>admin</username><!-- 登录nexus的密码 --><password>admin123</password></server><!-- 配置拦截器mirror登录的用户名密码。他会拦截所有的请求到mirror指定的地址下载jar包 如果只需要去私服下载jar包则只需配置此项 --><server><!-- id,对应mirror中id --><id>nexus</id><username>admin</username><password>admin123</password></server></servers><!-- 以下配置为下载jar包配置 通用 --><mirrors><!-- 强制让jar包下载走私服 --><mirror><id>nexus</id><mirrorOf>*</mirrorOf><url>http://192.168.65.129:8081/repository/maven-public/</url></mirror></mirrors><profiles><profile><!-- 对应activeProfiles-activeProfile的内容 --><id>nexus</id><!-- 仓库地址 --><repositories><repository><!-- 私服id,覆盖maven-model模块下的父id,让maven不走中央仓库下载,走私服下载 --><id>central</id><!-- 名字 --><name>Nexus</name><!-- 私服地址,写central后,会去mirror里面找 --><url>http://central</url><!-- 支持releases版本 --><releases><enabled>true</enabled></releases><!-- 支持snapshots版本 --><snapshots><enabled>true</enabled></snapshots></repository></repositories><!-- 插件地址 --><pluginRepositories><pluginRepository><id>central</id><name>Nexus Plugin Repository</name><url>http://central</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></pluginRepository></pluginRepositories><!-- 配置全局的url地址 供上传jar包时动态获取 --><properties><ReleaseRepository>http://192.168.65.129:8081/repository/maven-releases/</ReleaseRepository><SnapshotRepository>http://192.168.65.129:8081/repository/maven-snapshots/</SnapshotRepository></properties></profile></profiles><!-- 选择使用的profile --><activeProfiles><activeProfile>nexus</activeProfile><!-- <activeProfile>rdc</activeProfile>--></activeProfiles></settings>
6. 在项目的pom.xml文件中配置推送url地址
<distributionManagement><repository><id>nexus</id><name>nexus</name><url>http://xxxx:port/repository/maven-snapshots/</url></repository><snapshotRepository><id>maven-snapshots</id><name>maven-snapshots</name><url>http://xxxx:port/repository/maven-snapshots/</url></snapshotRepository></distributionManagement>
7. 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。
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><!-- 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
