In this post let's see how we can pass variables between jobs in Azure Pipelines.
Let's say we need to pass a variable from JobA to future jobs.
trigger:
- main/*
pool:
vmImage: ubuntu-latest
stages:
- stage: StageA
displayName: Stage A
jobs:
- job: JobA
displayName: Job A
steps:
# Create output variable and set value
- script: |
echo "##vso[task.setvariable variable=jobAVariable;isOutput=true]someValue"
name: outputVariable
displayName: Output Variable
- job: JobB
displayName: Job B
dependsOn: JobA
variables:
# Map the output variable from Job A into Job B
jobBVariable: $[ dependencies.JobA.outputs['outputVariable.jobAVariable'] ]
steps:
# This will print the updated value of the variable
- script: |
echo $(jobBVariable)
name: printUpdatedVariable
displayName: Print Updated Variable
- job: JobC
displayName: Job C
dependsOn: JobA
variables:
# Map the output variable from Job A into Job C
jobCVariable: $[ dependencies.JobA.outputs['outputVariable.jobAVariable'] ]
steps:
# This will print the updated value of the variable
- script: |
echo $(jobCVariable)
name: printUpdatedVariable
displayName: Print Updated Variable
Note how StageA.JobA.outputVariable is outputting the variable using isOutput=true. By default jobs run in parallel. So first we need to wait till JobA completes using dependsOn. Then we can map the variable into any job through dependencies.
Hope this helps.
Happy Coding.
