篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了k8s中jenkins构建maven项目22相关的知识，希望对你有一定的参考价值。

上次第20的内容是通过jenkins构建内容，但是没有使用maven进行编译

现在开始实现一下

1、首先使用jenkinssalve构建maven，就必须让jenkins有maven

首先基于原来的jenkins镜像，cnych/jenkins:jnlp6作为基础镜像然后把maven工具放到镜像，然后添加环境变量，可以出现mvn -version出现成功就行

网上有资料可以自己操作，这里是dockerfile的命令

2、配置jenkins

因为maven编译需要第三方包，一般不配置国内仓库回到国外下载，会有超时，所以要准备一个settings。xml文件

改成阿里的

然后创建configmap文件然后挂载到jenkinsslave的镜像

kubectl create configmap settings.xml --from-file=settings.xml -n kube-ops

接下来开始挂载，需要挂载的比较多

保存完成就行

3、开始构建，先简单测试一下使用-s指定settings.xml文件

node(\'haimaxy-jnlp\'){
stage(\'build\') {
echo "1.Clone Stage"
sh "mvn archetype:generate -DgroupId=org.javaboy -DartifactId=clb -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false -s /home/jenkins/settings/settings.xml"
}
stage(\'package\') {
echo "2.Test Stage"
sh "cd /home/jenkins/agent/workspace/kube-ops/clb && mvn package"
}
stage(\'install\') {
echo "3.Build Docker Image Stage"
sh "cd /home/jenkins/agent/workspace/kube-ops/clb && mvn install"
}
}

构建没有问题，说明maven没问题

4、开始构建一个tomcat项目

node(\'haimaxy-jnlp\'){
stage(\'Clone\') {
echo "1.Clone Stage"
git credentialsId: \'5789c68f-ebf6-45b8-b9e5-5648c1a3eb09\', url: \'http://139.155.71.51/root/tomcat.git\'
script {
//获取comment id
env.imageTag = sh (script: \'git rev-parse --short HEAD ${GIT_COMMIT}\', returnStdout: true).trim()
}
}

stage(\'build\') {
echo "2.mvn clean"
sh "cd /home/jenkins/agent/workspace/bbs/solo-master && mvn clean -Dmaven.test.skip=true install -s /home/jenkins/settings/settings.xml"
}
stage(\'build dockerfile\') {
echo "3.build dockerfile"
sh \'\'\'
cd /home/jenkins/agent/workspace/bbs/solo-master/target
REPOSITORY=10.4.7.52/cnych/jenkins-demo:${imageTag}
cat >> Dockerfile << EOF
FROM tomcat:7
RUN mkdir /usr/local/tomcat/webapps/ROOT
ADD ./solo.jar /usr/local/tomcat/webapps/ROOT
USER root
EOF
docker build -t $REPOSITORY .
\'\'\'
}
stage(\'docker push \') {
echo "docker run"
sh \'\'\'
REPOSITORY=10.4.7.52/cnych/jenkins-demo:${imageTag}
docker login http://10.4.7.52 -u admin -p Harbor12345
docker push $REPOSITORY
\'\'\'
}
stage(\'kubectl apply\'){
echo "kubectl apply"
sh \'\'\'
REPOSITORY=10.4.7.52/cnych/jenkins-demo:${imageTag}
cat >> tomcat.yaml << EOF
