Pass a value to a shell script from jenkins pipeline - bash

Question

How to pass values to a shell script from jenkins during the runtime of the pipeline job.
I have a shell script and want to pass the values dynamically.
#!/usr/bin/env bash
....
/some code
....
export USER="" // <--- want to pass this value from pipeline
export password="" //<---possibly as a secret
The jenkins pipeline executes the above shell script
node('abc'){
stage('build'){
sh "cd .."
sh "./script.sh"
}
}

You can do something like the following:
pipeline {
agent any
environment {
USER_PASS_CREDS = credentials('user-pass')
}
stages {
stage('build') {
steps {
sh "cd .."
sh('./script.sh ${USER_PASS_CREDS_USR} ${USER_PASS_CREDS_PSW}')
}
}
}
}
The credentials is from using the Credentials API and Credentials plugin. Your other option is Credentials Binding plugin where it allows you to include credentials as part of a build step:
stage('build with creds') {
steps {
withCredentials([usernamePassword(credentialsId: 'user-pass', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {
// available as an env variable, but will be masked if you try to print it out any which way
// note: single quotes prevent Groovy interpolation; expansion is by Bourne Shell, which is what you want
sh 'echo $PASSWORD'
// also available as a Groovy variable
echo USERNAME
// or inside double quotes for string interpolation
echo "username is $USERNAME"
sh('./script.sh $USERNAME $PASSWORD')
}
}
}
Hopefully this helps.
