Jenkins assign input to environment variable - jenkins

Trying to assign user input from 1 stage to use in another stage , thought to do it with env variables but cant figure it out
code so far :
environment {
access_key =''
}
stages {
stage('User input for Auth'){
input {
message 'enter access_key'
parameters {
string 'access_key_input'
string 'secret_key_input'
}
}
environment {
access_key = sh(script:"echo ${access_key_input}", returnStdout: true).trim()
}
steps{
sh "echo ${env.access_key}"
}
}
stage("Build") {
steps {
sh "echo ${env.access_key}"
}
}
}
logs :
+ echo XXX
+ echo XXX
XXX
+ echo null
null

You can assign the input to a global variable and then access that wherever you want.
def INPUT_PARAMS = null
pipeline {
agent {
node {
label 'any'
}
}
options {
timestamps()
}
stages {
stage('User input for Auth') {
steps{
script {
INPUT_PARAMS = input message: "enter access_key", parameters: [
string(description: 'Access key', defaultValue: '', name: 'access_key_input'),
string(description: 'Secret access key', defaultValue: '', name: 'secret_key_input')
]
}
sh "echo ${INPUT_PARAMS.access_key_input}"
}
}
stage("Build") {
steps {
sh "echo ${INPUT_PARAMS.access_key_input}"
}
}
}
}

Jenkins Declarative Piplines- Script is unable to pickup parameter as varible

I am New to Jenkins. Trying to create one basic Pipeline which is using choicebased parameters. Following is my script.
Code ----
pipeline{
agent {
label 'agent'
}
parameters {
choice choices: ['John', 'Stacy'], description: 'Choose one', name: 'Person'
}
stages {
stage('Print') {
steps {
echo "Hello ${params.Person}"
sh """if (${params.Person} = "John")
then
echo "Person is male."
else
echo "Person is female."
fi"""
}
}
}
}
Now my build complete successfully regardless of whatever option I choose. It always display result "Person is female.
Following is result of one of my build.
Started by user ****
[Pipeline] Start of Pipeline

/home/temp/jenkins_agent/workspace/ChoiceBased PL
[Pipeline] {

[Pipeline] sh

/home/temp/jenkins_agent/workspace/ChoiceBased PL#tmp/durable-

+ echo Person is female.
Person is female.
[Pipeline] }
[Pipeline] // stage
[Pipeline] }

Please suggest what I am missing ?
I would change this just to be in Groovy rather than doing the compare in sh
stage('Print') {
steps {
echo "Hello ${params.Person}"
script {
if (params.Person == "John") {
echo "Person is male."
} else {
echo "Person is female."
}
}
}
}
Then when you choose Stacey you will get
[Pipeline] echo
Hello Stacy
[Pipeline] script
[Pipeline] {
[Pipeline] echo
Person is female.
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }

Jenkins Pipeline with conditional "When" expression of choice parameters

I'm new to Groovy. I'm not able to figure out what's wrong here.
Depends on the choice of input, I expect the script to execute either Step 'Hello' or 'Bye' but it skips both. I mostly orientated to this Jenkins pipeline conditional stage using "When" for choice parameters, but still can't figure it out.
How can I use those choice parameters correctly?
pipeline {
agent any
stages {
stage('Init') {
steps('Log-in'){
echo 'Log-in'
}
}
stage('Manual Step') {
input {
message "Hello or Goodbye?"
ok "Say!"
parameters{choice(choices:['Hello','Bye'], description: 'Users Choice', name: 'CHOICE')}
}
steps('Input'){
echo "choice: ${CHOICE}"
echo "choice params.: " + params.CHOICE //null
echo "choice env: " + env.CHOICE //Hello
}
}
stage('Hello') {
when{ expression {env.CHOICE == 'Hello'}}
steps('Execute'){
echo 'Say Hello'
}
}
stage('Bye') {
when{ expression {env.CHOICE == 'Bye'}}
steps('Execute'){
echo 'Say Bye'
}
}
}
}
Output:
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Init)
[Pipeline] echo
Log-in
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Manual Step)
[Pipeline] input

[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Hello)

[Pipeline] }
[Pipeline] // stage

[Pipeline] { (Bye)

[Pipeline] }
[Pipeline] // stage

[Pipeline] // node
[Pipeline] End of Pipeline

From the docs:
Any parameters provided as part of the input submission will be available in the environment for the rest of the stage.
This means that your parameter CHOICE does not exist in the other stages. If you want to have a parameter that's available on all the stages, you can define a parameter outside of the stage, i.e.:
pipeline {
agent any
parameters {
choice(choices:['Hello','Bye'], description: 'Users Choice', name: 'CHOICE')
}
stages {
stage('Init') {
steps('Log-in') {
echo 'Log-in'
}
}
stage('Manual Step') {
steps('Input') {
echo "choice: ${CHOICE}"
echo "choice params.: " + params.CHOICE
echo "choice env: " + env.CHOICE
}
}
stage('Hello') {
when {
expression { env.CHOICE == 'Hello' }
}
steps('Execute') {
echo 'Say Hello'
}
}
stage('Bye') {
when {
expression {env.CHOICE == 'Bye'}
}
steps('Execute'){
echo 'Say Bye'
}
}
}
}
This will behave as expected. The difference is that the job won't ask you for input, instead, you will provide the wanted parameters before pressing build.

Jenkinsfile does not take into account conditional on branch

Here are the stages of my Jenkinsfile
stages {
stage("build") {
when {
expression {
BRANCH_NAME = 'alerta_dev_infra'
}
}
steps {
echo 'buidling the webhook'
}
}
stage("test") {
when {
expression {
env.BRANCH_NAME = 'alerta*'
}
}
steps {
echo 'testing the webhook'
}
}
stage("deploy") {
when {
expression {
env.BRANCH_NAME = 'alerta_dev_infra'
}
}
steps {
echo 'deploying the webhook'
}
}
}
However, when it is executed:
14:10:00 Push event to branch alerta_dev_infra
14:10:00 Started by user pkaramol#foo.bar
14:10:00 Rebuilds build #9
14:10:49 First time build. Skipping changelog.
14:10:49 [Pipeline] }
14:10:49 [Pipeline] // stage
14:10:49 [Pipeline] withEnv
14:10:49 [Pipeline] {
14:10:49 [Pipeline] container
14:10:49 [Pipeline] { (hide)
14:10:49 [Pipeline] stage
14:10:49 [Pipeline] { (build)
14:10:49 Stage "build" skipped due to when conditional
14:10:49 [Pipeline] }
14:10:50 [Pipeline] // stage
14:10:50 [Pipeline] stage
14:10:50 [Pipeline] { (test)
14:10:50 Stage "test" skipped due to when conditional
14:10:50 [Pipeline] }
14:10:50 [Pipeline] // stage

14:10:50 [Pipeline] // node
14:10:50 [Pipeline] }
14:10:50 [Pipeline] // podTemplate
14:10:50 [Pipeline] End of Pipeline
This worked for me
when {
expression {
return env.GIT_BRANCH == "origin/master"
}
}
I have used the Choice Parameter to provide three choices for branch to select: master, develop and feature-1
Here is the pipeline code to use when conditional on BRANCH_NAME parameter
pipeline {
agent any
stages {
stage ('Build in master') {
when {
expression { params.BRANCH_NAME == 'master' }
}
steps {
echo "Building in master"
}
}
stage ('Build in develop')
{
when {
expression { params.BRANCH_NAME == 'develop' }
}
steps {
echo "Building in develop"
}
}
stage ('Build in feature')
{
when {
expression { params.BRANCH_NAME == 'feature-1' }
}
steps {
echo "Building in feature-1"
}
}
}
}

Jenkins input on declarative pipeline

may I ask if it is do-able if I can get the user input and run a script based on what was chosen by the user? the logic whould be
IF User choose Proceed THEN run a script (in my case promote or Blue/Green deployment)
IF User choose Abort THEN don't terminate the jenkins job, run a script (in my case rollback)
This is the script I'm using however I have no idea how to apply after validate stage
pipeline {
agent any
stages {
stage('Deploy') {
steps {
sh """#!/bin/bash +x
echo "performing sts assume role"
//SCRIPT-HERE//
echo "performing ansible deploy"
//SCRIPT-HERE//
"""
}
}
stage('validate') {
steps {
timeout(30) {
script {
input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')
}
}
}
}
}
}
One more issue I'm seeing is, although this pipeline script is running, The Proceed / Abort is not clickable on the jenkins job Console output, is it a bug? I'm referring to the image shown below
I was able to add nandilov's suggestion however it seems that the logic is still not applying, please advise on what is missed here
pipeline {
agent any
stages {
stage('Deploy') {
steps {
sh """#!/bin/bash +x
echo "performing sts assume role"
echo "performing ansible deploy"
"""
}
}
stage('validate') {
steps {
script {
env.flagError = "false"
try {
input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')
}catch(e){
println "input aborted or timeout expired, will try to rollback."
env.flagError = "true"
}
}
}
}
stage("If user selects Proceed"){
when{
expression { env.inputValue == "value1" }
}
steps{
sh """#!/bin/bash +x
echo "User selected proceed"
"""
}
}
stage("rollback if flag error true"){
when{
expression { env.inputValue == "value2" }
}
steps{
sh """#!/bin/bash +x
echo "User selected Abort"
"""
}
}
}
}
from the pipeline view it never triggered either one of the last two stages when choosing "Abort" or "Proceed"
These are the logs when choosing Abort or Proceed

If you want to have the job aborted and do something, you can try/catch it:
try{
input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')
}catch(e){
println "input aborted or timeout expired, will try to rollback."
// execute rollback
}
You also can do it in another stage:
pipeline {
agent any
stages {
stage('Deploy') {
steps {
sh """#!/bin/bash +x
echo "performing sts assume role"
echo "performing ansible deploy"
"""
}
}
stage('validate') {
steps {
script {
env.flagError = "false"
try {
input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')
}catch(e){
println "input aborted or timeout expired, will try to rollback."
env.flagError = "true"
}
}
}
}
stage("If user selects Proceed"){
when{
expression { env.flagError == "false" }
}
steps{
sh """#!/bin/bash +x
echo "User selected proceed"
"""
}
}
stage("rollback if flag error true"){
when{
expression { env.flagError == "true" }
}
steps{
sh """#!/bin/bash +x
echo "User selected Abort"
"""
}
}
}
Try with this, you will need to click on Proceed and then to choose between "deploy" and "rollback". The result we'll be store in an environment variable and you can use it as a condition on the next stages
stage('validate') {
steps {
timeout(30) {
script {
CHOICES = ["deploy", "rollback"];
env.yourChoice = input message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok : 'Proceed',id :'choice_id',
parameters: [choice(choices: CHOICES, description: 'Do you want to deploy or to rollback?', name: 'CHOICE'),
string(defaultValue: 'rollback', description: '', name: 'rollback value')]
}
}
}
}
}
stage('Deploy') {
when {
expression { env.yourChoice == 'deploy' }
}
steps {
...
}
}
stage('Rollback') {
when {
expression { env.yourChoice == 'rollback' }
}
steps {
...

jenkinsfile not passing env to sh

I am trying to set environment variable in Jenkinsfile following way,
pipeline {
agent { label 'slave1' }
stages {
stage ('Build') {
steps {
script {
BUILD_VERSION = sh (
script: 'python get_firmware_version.py',
returnStdout: true
).trim()
}
echo "${BUILD_VERSION}"
withCredentials([file(credentialsId: 'image-sign', variable: 'IMAGE_SIGN')]) {
dir('firmware/') {
echo "${BUILD_VERSION}"
sh '''
echo "Building"
echo "${BUILD_VERSION}"
echo "${env.BUILD_VERSION}"
'''
}
}
}
}
}
post {
failure {
script {
echo "Pipeline Failed"
}
}
}
}
But its failing with following error Bad substitution
[Pipeline] echo
0_2_0
[Pipeline] sh
+ echo Building
Building
/home/jenkins/jenkins_slave/workspace/Firmware/Branch/firmware#tmp/durable-54e04481/script.sh: 3: /home/jenkins/jenkins_slave/workspace/Firmware/Branch/firmware#tmp/durable-54e04481/script.sh: Bad substitution
Why I can't set ENV Var and use it in sh step ?
This is Jenkins thing I think. When you use the sh block with '; it will not have access to things like environment variables. Try using the " instead. That should work
sh """
echo "Building"
echo "${env.BUILD_VERSION}"
echo "${env}"
"""
Jenkins should recognise the shell block and escape the " within the """ automatically.
pipeline {
agent { label 'slave1' }
stages {
stage ('Build') {
steps {
script {
BUILD_VERSION = sh (
script: 'python get_firmware_version.py',
returnStdout: true
).trim()
}
echo "${BUILD_VERSION}"
withCredentials([file(credentialsId: 'image-sign', variable: 'IMAGE_SIGN')]) {
dir('firmware/') {
echo "${BUILD_VERSION}"
sh """
echo "Building"

echo "${env.BUILD_VERSION}"

}
}
}
}
}
post {
failure {
script {
echo "Pipeline Failed"
}
}
}
}
My test case
pipeline {
agent {
