jenkins pipeline 远程部署war包到tomcat8.5

1.搭建一个支持远程部署的tomcat

2.新建一个java web项目

3.改造一下项目目录结构

在WEB-INF下添加两个文件夹：classes和lib。然后每个文件夹下新建一个.gitkeep的文件（防止在用git push时忽略这个文件夹）。

4.新建build.xml内容如下：

<project name="testAnt" default="redeploy" basedir="."><!-- Configure the directory into which the web application is built --><property name="build" value="${basedir}/web/WEB-INF/classes" /><property name="dist.dir" value="${basedir}/dist" /><!-- Configure the context path for this application --><property name="path" value="./" /><!-- Configure properties to access the Manager application --><property name="url" value="http://0.0.0.0:8888/manager/text" /><property name="username" value="username" /><property name="password" value="password" /><taskdef name="deploy"    classname="org.apache.catalina.ant.DeployTask"></taskdef><taskdef name="undeploy"  classname="org.apache.catalina.ant.UndeployTask"/><!-- Configure the custom Ant tasks for the Manager application --><target name="deploy" description="Install web application" depends="compile"><deploy url="${url}" username="${username}" password="${password}" path="/test" war="${dist.dir}/testAnt.war"/></target><target name="undeploy" description="Remove web application"><undeploy url="${url}" username="${username}" password="${password}" path="/test"/></target><!-- Executable Targets --><target name="compile" description="WebSip manage"><mkdir dir="${dist.dir}"/><war destfile="${dist.dir}/testAnt.war" webxml="web/WEB-INF/web.xml"><classes dir="web/WEB-INF/classes" /><fileset dir="web" excludes="WEB-INF/**" /><lib dir="web/WEB-INF/lib" /></war></target><target name="redeploy" description="Remove and Install web application" ><antcall target="undeploy"/><antcall target="deploy"/></target>
</project>

5.添加依赖包

从tomcat中复制catalina-ant.jar到ant的lib中 获取catalina-ant.jar可以通过如下方式获取

docker run --rm -v /root/tomcatconf/:/home/  tomcat cp /usr/local/tomcat/lib/catalina-ant.jar /home/

在/root/tomcatconf中会多出这个文件。

6.在项目路径下执行ant命令

查看是否能够部署成功

7.把该工程上传到gitlib/hub

git init
git remote add 
git add *
git commit -m "init"
git push

8.自定义ant镜像。

新建一个文件夹。将 第5步中获取的catalina-ant.jar放到该文件夹中。然后在这个文件夹中新建一个名为dockerfile的文件 vim dockerfile ,dockerfile内容如下：

FROM frekele/ant:latest
COPY catalina-ant.jar /opt/ant/lib/catalina-ant.jar

然后在这个文件夹中执行 docker build ./ -t docker_image_name 将这个docker image推送到远程docker仓库 docker push docker_image_name 也可以获取我已经做好的 docker pull s7799653/ant_to_tomcat

9.jenkins pipeline

podTemplate(cloud: 'default',namespace: 'dzzw',label: 'ant', containers: [containerTemplate(name: 'ant', image: 'docker-local.repo.***.com/ant/ant_to_tomcat:a1.10_t8.5', ttyEnabled: true, command: 'cat', args: ''),containerTemplate(name: 'jnlp', image: "docker-local.repo.***.com/jenkins/jnlpwithssh:0.2", ttyEnabled: true, command: '', args: '${computer.jnlpmac} ${computer.name}')],volumes: [hostPathVolume ( hostPath: '/var/run/docker.sock', mountPath: '/var/run/docker.sock')],imagePullSecrets: ['artifactory']
)node('ant') {sh 'git clone git.***.com:songjxin/ant_deploy_to_tomcat.git';stage(' 获取代码并发布') {container('ant') {sh 'echo "nameserver 10.100.1.58">> /etc/resolv.conf';sh 'cd ant_deploy_to_tomcat && ls && ant'}}
}

我在jnlp镜像加了私钥。可以通过ssh的方式clone代码。如果没有可以通过http://username:password@git****的方式获取
