没有让Docker在Jenkins中运行 [英] Not getting Docker to run from within Jenkins
问题描述
我有一条Jenkins-Pipeline,可以成功构建docker-image。
但是在运行docker-image时会失败。
在docker镜像中,我有一些我想与ctest一起运行的API测试。
可以通过在目录/ testing中调用test来执行测试。
I have a Jenkins-Pipeline that successfully builds a docker-image. But when it comes to running the docker-image it fails. Inside the docker image I have some API-tests that I want to run with ctest. The tests can be executed by calling test in the directory /testing.
有任何建议吗?
pipeline {
agent {label 'apitest-centos7'}
stages {
stage('cleanup'){
steps{
cleanWs()
}
}
stage('git checkout Dockerfile') {
steps{
checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'ebf01b-3gf93-4f8e-9f69-97ffgff308af', url: 'http://gitlab.somecompany.loc/somecompany/MyApiTestingTools.git']]])
sh 'ls'
}
}
stage('build Dockerimage'){
steps{
dir('dockerbuild'){
fileExists 'Dockerfile'
sh 'sudo docker build --no-cache=true -t apitestimage .'
}
}
}
stage('start Dockerimage and Tests') {
steps{
dir("dockerbuild"){
withDockerContainer(args: "-ti apitestimage bash -c 'cd testing && ctest", image: 'apitestimage') {
}
}
}
}
}
post {
always {
/*mattermostSend color: 'good', message: 'API-Tests have been executed'*/
deleteDir() /* clean up our workspace */
}
success {
mattermostSend color: 'good', message: 'API-Tests succeded', channel: 'api-tests'
}
unstable {
mattermostSend color: 'warning', message: 'API-Tests are unstable', channel: 'api-tests'
}
failure {
mattermostSend color: 'danger', message: 'API-Tests have failed', channel: 'api-tests', icon: 'https://talks.bitexpert.de/zendcon16-jenkins-for-php-projects/images/jenkins.png'
}
changed {
mattermostSend color: 'warning', message: 'API-Tests have changed', channel: 'api-tests'
}
}
}
推荐答案
我会猜测s出现错误的3个原因:
I would guess 3 reasons for an error:
- 您正在尝试使用tty(
-it
选项)在没有tty的非交互式环境(jenkins构建环境)中,这可能会引起一些问题 - 您为图像名称输入了两次:
args
和image
- 您没有关闭报价
- you're trying to launch the container interactive mode with tty (
-it
options) in a non-interactive without tty environment (the jenkins build environment), which may cause some problems - you're giving the image name twice: in
args
andimage
- you're not closing a quote
尝试更改为:
withDockerContainer(args: "bash -c 'cd testing && ctest'", image: 'apitestimage')
顺便说一句,您可以考虑使用 docker管道API :
stage('build Dockerimage') {
steps {
script {
apitestimage = docker.build('apitestimage', '--no-cache=true dockerbuild')
}
}
}
stage('start Dockerimage and Tests') {
steps{
script {
apitestimage.inside {
sh 'cd testing && ctest'
}
}
}
}
作为 docker.inside
在当前工作空间上安装一个卷,您甚至可以避免创建映像的步骤(您不发布它,所以我想这仅是测试所必需的),并从基本映像以构建测试环境并启动测试。
As the docker.inside
mount a volume on the current workspace, you even could avoid the image creation step (you don't publish it, so I guess it's only necessary for tests) and launch the necessary commands from a base image to build the test environment and launch the tests.
