Mirroring warehouse configuration

 

 jenkins in maven configuration settings login harbor setting.xml- address and account password

Previous push in the mirror when needed

File Location: /var/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/mvn3.6.3/conf

 New Server Node

<server>
    <id>yourrepositoryurl</id>
    <username>admin</username>

dockerfile Configuration

FROM openjdk:8u181-jdk-alpine
ARG workdir=/app
VOLUME ${workdir}
WORKDIR ${workdir}
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
EXPOSE 8080
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","app.jar"]

System Settings - Global tool configuration jdk maven

 

 

 

 

 

 jenkins新建一个job 使用maven构建

连接git

 

 

插件version number生成构建版本号

${BUILD_DATE_FORMATTED,"yyyyMMdd"}.${BUILDS_TODAY}

View Code

 

 

 执行maven构建命令

clean package -Dmaven.test.skip=true -P dev

View Code

 

 使用版本号tag新的镜像并push到harbor上

 执行脚本push镜像到私有registry报没有权限的错

 

 

 

 

解决方法:需要login私有registry(在Jenkins容器内执行login命令)

执行成功后会在root/.docker文件夹下生成config.json文件(含有login私有registry的凭证)

 

 ssh指定服务器pull镜像并run - 插件Publish Over SSH
