run my test in docker mongo instance using jenkins pipeline - mongodb

Question

I would like to run my tests against a Docker MongoDB instance using Jenkins pipeline. I have got it working kind of. My problem is the tests are running within the Mongo container. I just want it to load up a container and my tests for it to connect to the Monogo container. At the moment it downloads Gradle within the container and takes about 5 min to run. Hope that makes sense. Here is my JenkinsFile
#!/usr/bin/env groovy
pipeline {
environment {
SPRING_PROFILES_ACTIVE = "jenkins"
}
agent {
node {
label "jdk8"
}
}
parameters {
choice(choices: 'None\nBuild\nMinor\nMajor', description: '', name: 'RELEASE_TYPE')
string(defaultValue: "refs/heads/master:refs/remotes/origin/master", description: 'gerrit refspec e.g. refs/changes/45/12345/1', name: 'GERRIT_REFSPEC')
choice(choices: 'master\nFETCH_HEAD', description: 'gerrit branch', name: 'GERRIT_BRANCH')
}
stages {
stage("Test") {
stages {
stage("Initialise") {
steps {
println "Running on ${NODE_NAME}, release type: ${params.RELEASE_TYPE}"
println "gerrit refspec: ${params.GERRIT_REFSPEC}, branch: ${params.GERRIT_BRANCH}, event type: ${params.GERRIT_EVENT_TYPE}"
checkout scm
sh 'git log -n 1'
}
}
stage("Verify") {
agent {
dockerfile {
filename 'backend/Dockerfile'
args '-p 27017:27017'
label 'docker-pipeline'
dir './maintenance-notifications'
}
}
steps {
sh './gradlew :maintenance-notifications:backend:clean'
sh './gradlew :maintenance-notifications:backend:check :maintenance-notifications:backend:test'
}
post {
always {
junit 'maintenance-notifications/backend/build/test-results/**/*.xml'
}
}
}
}
}
stage("Release") {
when {
expression {
return params.RELEASE_TYPE != '' && params.RELEASE_TYPE != 'None';
}
}
steps {
script {
def gradleProps = readProperties file: "gradle.properties"
def isCurrentSnapshot = gradleProps.version.endsWith("-SNAPSHOT")
def newVersion = gradleProps.version.replace("-SNAPSHOT", "")
def cleanVersion = newVersion.tokenize(".").collect{it.toInteger()}
if (params.RELEASE_TYPE == 'Build') {
newVersion = "${cleanVersion[0]}.${cleanVersion[1]}.${isCurrentSnapshot ? cleanVersion[2] : cleanVersion[2] + 1}"
} else if (params.RELEASE_TYPE == 'Minor') {
newVersion = "${cleanVersion[0]}.${cleanVersion[1] + 1}.0"
} else if (params.RELEASE_TYPE == 'Major') {
newVersion = "${cleanVersion[0] + 1}.0.0"
}
def newVersionArray = newVersion.tokenize(".").collect{it.toInteger()}
def newSnapshot = "${newVersionArray[0]}.${newVersionArray[1]}.${newVersionArray[2] + 1}-SNAPSHOT"
println "release version: ${newVersion}, snapshot version: ${newSnapshot}"
sh "./gradlew :maintenance-notifications:backend:release -Prelease.useAutomaticVersion=true -Prelease.releaseVersion=${newVersion} -Prelease.newVersion=${newSnapshot}"
}
}
}
}
}
and here is my Dockerfile
