I'm new with Jenkins, and I would like to get almost the same behavior as in GitLab CI for one of my PHP project.

I use Docker to test my project on several PHP versions.

What I want ?

Running build and test in parallel.

• Build creates my application, sources come from a git repository, and I run the composer install command.


• Dockerfile is stored in /var/lib/jenkins/Docker
  


• My Dockerfile has a parameter (PHP_VERSION) which allow me to choose the PHP version I want


• 
  customWorkspace seems to work

Here is my Jenkinsfile to do so :

updateGitlabCommitStatus name: 'build', state: 'pending'

pipeline 
 agent none
 post 
 failure 
 updateGitlabCommitStatus name: 'build', state: 'failed'
 
 success 
 updateGitlabCommitStatus name: 'build', state: 'success'
 
 
 stages 

 stage('build') 

 parallel 
 stage('build-php5.4') 
 agent 
 dockerfile 
 additionalBuildArgs '--build-arg PHP_VERSION=54'
 dir '/var/lib/jenkins/Docker'
 customWorkspace './build-php5.4'
 
 
 steps 
 sh 'pwd'
 sh 'ls'
 sh 'rm -Rf composer.lock vendor'
 sh 'composer install'
 
 

 stage('build-php7.0') 
 agent 
 dockerfile 
 additionalBuildArgs '--build-arg PHP_VERSION=70'
 dir '/var/lib/jenkins/Docker'
 customWorkspace './build-php7.0'
 
 
 steps 
 sh 'pwd'
 sh 'rm -Rf composer.lock vendor'
 sh 'composer install'
 
 
 

 

 stage('tests') 

 parallel 
 stage('test-php5.4') 
 agent 
 dockerfile 
 additionalBuildArgs '--build-arg PHP_VERSION=54'
 dir '/var/lib/jenkins/Docker'
 customWorkspace './build-php5.4'
 
 
 steps 
 sh 'pwd'
 sh 'php --version'
 sh 'php vendor/phpunit/phpunit/phpunit tests'
 
 

 stage('test-php7.0') 
 agent 
 dockerfile 
 additionalBuildArgs '--build-arg PHP_VERSION=70'
 dir '/var/lib/jenkins/Docker'
 customWorkspace './build-php7.0'
 
 
 steps 
 sh 'pwd'
 sh 'php --version'
 sh 'php vendor/phpunit/phpunit/phpunit tests'
 
 
 
 
 

And here is the result :

It looks good, but it isn't, and I don't really understand the underlying behavior.

As you can see, the test-php54 stage uses the last created Docker container :

I'm sure I'm wrong on a lot of steps, but do you think I can do it this way ?

Ok, I found the main problem.

The fact is I use the same Dockerfile, but with different parameters.
If I create one Dockerfile for PHP 5.4 and another one for PHP 7.0, the stages are parallelized correctly.

updateGitlabCommitStatus name: 'build', state: 'pending'

pipeline 
 agent none
 post 
 failure 
 updateGitlabCommitStatus name: 'build', state: 'failed'
 
 success 
 updateGitlabCommitStatus name: 'build', state: 'success'
 
 
 stages 

 stage('build') 

 parallel 
 stage('build-php5.4') 
 agent 
 dockerfile 
 dir '/var/lib/jenkins/Docker'
 filename 'Dockerfile-php5.4'
 customWorkspace './build-php5.4'
 
 
 steps 
 sh 'rm -Rf composer.lock vendor'
 sh 'composer install'
 
 

 stage('build-php7.0') 
 agent 
 dockerfile 
 dir '/var/lib/jenkins/Docker'
 filename 'Dockerfile-php7.0'
 customWorkspace './build-php7.0'
 
 
 steps 
 sh 'rm -Rf composer.lock vendor'
 sh 'composer install'
 
 
 

 

 stage('tests') 

 parallel 
 stage('test-php5.4') 
 agent 
 dockerfile 
 dir '/var/lib/jenkins/Docker'
 filename 'Dockerfile-php5.4'
 customWorkspace './build-php5.4'
 
 
 steps 
 sh 'php --version'
 sh 'php vendor/phpunit/phpunit/phpunit tests'
 
 

 stage('test-php7.0') 
 agent 
 dockerfile 
 dir '/var/lib/jenkins/Docker'
 filename 'Dockerfile-php7.0'
 customWorkspace './build-php7.0'
 
 
 steps 
 sh 'php --version'
 sh 'php vendor/phpunit/phpunit/phpunit tests'
 
 
 
 
 

This seems to work ! :)
