容器化Jenkins远程发布java应用（方式一：pipline+ssh）

1.创建pipline工程

2.准备工程Jenkinsfile文件（java目录）

1.文件脚本内容

env.fileName = "planetflix-app.jar"
env.configName = "planetflix_prod"
env.remoteDirectory = "/data/project/java"
env.sourceFile = "/var/jenkins_home/workspace/release_planetxflix_pipline/planetflix-api/target/${env.fileName}"
env.shellName="devops.sh"
env.shellDirectory = "/home/planetflix/shell"pipeline{agent any//定义流水线的加工流程stages {stage('打JAR包') {steps {sh label:'',script: 'mvn clean package -Dmaven.test.skip=true'}}stage('推送部署文件到远程服务器') {steps {sh """cp -f ${env.sourceFile} ./"""sshPublisher(publishers: [sshPublisherDesc(configName: "${env.configName}", transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: 'echo "...成功推送planetflix-app.jar..."', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: "${env.remoteDirectory}", remoteDirectorySDF: false, removePrefix: '', sourceFiles: "${env.fileName}")], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])echo '推送成功'}}stage('运行部署') {steps { sshPublisher(publishers: [sshPublisherDesc(configName: "${env.configName}", transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand:"sh ${env.shellDirectory}/${env.shellName}", execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])echo "部署完成"}}}
}

2.devops.sh文件

3.app.yml（docker-compose）

4.Java服务Dockerfile
