I have written a simple pipeline script to show the usage of variable in bash script.
Pipeline script:
pipeline {
agent any
parameters {
choice(name: 'stageparam', choices: ['build', 'deploy'], description: 'enter stageparam')
string(name: 'USERNAME', defaultValue: 'abc', description: 'enter username')
}
stages {
stage('Git Pull')
{
steps {
checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'gitlab-test', url: 'http://localhost:8076/test-upgrade.git']]])
}
}
stage('Run the python script') {
steps {
sh 'chmod 777 test.py'
sh "python test.py ${env.WORKSPACE}"
}
}
stage('Run the bash script') {
steps {
sh 'chmod 777 run.sh'
sh "./run.sh ${env.USERNAME}"
}
}
}
}
Output:
