jenkins - 组织 Jenkins 库

1）共享库项目文件夹结构：

如上图，你可以在文件夹中组织文件夹结构src，就像组织java包一样。

然后将它们导入vars我们声明全局变量的文件夹中。

2) 内容vars/acidReleaseProcess.groovy：

#!groovy

import com.fmr.pipeline.AcidReleaseProcess

def relProcess

/**
 * Create a instance of class: AcidReleaseProcess
 * 
 * @param  appName uDeploy Application Name
 * @param  compName uDeploy Component Name
 * @param  compVersion component version to deploy
 * @return A self reference
 */
def call(appName, compName, compVersion) {
    relProcess = new AcidReleaseProcess(this, appName, compName, compVersion)   
    return this
}

/**
 * Execute Install, Go Live and Stop process on specify env
 * 
 * @param  envName name of environment to delpoy, exmaple: 'DIT', 'PAC', 'XQ1'
 */
def blueGreenDeploy(envName) {
    relProcess.deployToPassive(envName)
    relProcess.swapPassiveToActive(envName)
    relProcess.stopPassive(envName)
}

3)com.fmr.pipeline.AcidReleaseProcess.groovy

class AcidReleaseProcess implements Serializable {

    def script, appName, uDeployVers, passiveGroup = [:]

    AcidReleaseProcess(script, appName, compName, compVersion) {
        this.script = script 
        this.appName = appName
        this.uDeployVers = compName + ":" + compVersion
    }

    def deployToPassive(envName) {

        script.echo "Checking uDeploy environment ${envName} group state"

        script.sh 'docker pull ...'

        script.withCredentials([script.string(credentialsId: '<...>', variable: 'UDEPLOY_AUTH_TOKEN')]) {

            def group1_state = script.sh(
                        returnStdout: true, 
                        script: "docker run --rm -i ... \
                                    -a ${appName} \
                                    -e ${envName}-${group1} " + '-t ${UDEPLOY_AUTH_TOKEN}'
                    ).trim()

            def group2_state = script.sh(
                        returnStdout: true, 
                        script: "docker run --rm -i ...y \
                                    -a ${appName} \
                                    -e ${envName}-${group2} " + '-t ${UDEPLOY_AUTH_TOKEN}'
                    ).trim()

            script.echo "${envName}-${group1} is ${group1_state}, ${envName}-${group2} is ${group2_state}"

            if("${group1_state}" == "Live" && "${group2_state}" == "Live") {

                script.echo "Environment: ${envName}, ${group1} and ${group2} both are Live," +  
                     "only allow install on Non-Live environment"

                script.sh 'exit 1'
            } 

            def groupName = "${group1_state}" != "Live" ? group1 : group2

            passiveGroup[envName] = groupName
        }


        def uDeployEnv = envName + '-' + passiveGroup[envName]

        script.echo "Install on ${uDeployEnv}"

        script.step([
            $class  : 'UCDeployPublisher',
            siteName: 'pi_udeploy_srvpiudupload',
            deploy  : [
                    $class:             'com.urbancode.jenkins.plugins.ucdeploy.DeployHelper$DeployBlock',
                    deployApp:          appName,
                    deployEnv:          uDeployEnv,
                    deployProc:         UDEPLOY_INSTALL_PROC_NAME,
                    deployVersions:     uDeployVers,
                    deployOnlyChanged:  false
            ]
        ])
    }
}

4) 文件vars夹中的文件内容尽量简单，将可复用或复杂的代码组织到文件src夹下的类文件中。

5）一些提示：

将管道对象传递给 src 文件夹中的类

relProcess = new AcidReleaseProcess(this, appName, compName, compVersion) // this is the pipeline object
将管道对象存储在类构造函数中 AcidReleaseProcess(script, appName, compName, compVersion) { this.script = script // script here is the pipeline object
所有全局名称都需要以管道对象为前缀：script

sh -> script.sh echo -> script.echo with... -> script.with... string -> script.string etc...
