JenkinsのビルドをDockerコンテナで実行する

Docker Jenkins

やること

Spring Bootで作ったアプリケーションのビルド＆テストを、Jenkinsを使ってDockerコンテナ内で実行する。

方法

コンテナのイメージはopenjdk:8-jdk-alpineを使った。
Jenkinsfileの書き方は、agentにanyを指定するか、dockerを指定するかでコンテナ内で実行するかしないかがかわる。
mavenをコンテナに入れるの面倒なのでSpring Initlizr で作った時から入っている、mvnwを使う。
Junitの結果のグラフがなぜか表示されなかったけど、Wikiのコメントに回避策が書いてあった。一応動いた。 https://wiki.jenkins.io/display/JENKINS/JUnit+graph
maven-surefire-pluginのバージョンは2.20にしないとテストの実行が失敗する。

以下のようなJenkinsfileを作る。

pipeline {
    agent {
        docker {
            image 'openjdk:8-jdk-alpine'
        }
    }
    stages {
        stage('Checkout') {
            steps {
                checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[url: 'http://192.168.56.6:8081/gitbucket/git/root/dockertest.git']]])
            }
        }
        stage('Build') {
            steps {
                sh './mvnw clean compile'
            }
        }
        stage('Test') {
            steps {
                sh './mvnw test'
                
            }
        }
        stage('Recoding Result') {
            steps {
                //junit '**/surefire-reports/*.xml'
                step([$class: 'JUnitResultArchiver', testResults: '**/surefire-reports/*.xml' ])
            }
        }
    }
}

実行結果

実行するとこんな感じ。
