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"
			}
		}
	}
}
