setup environment variables in azure devops pipeline code example
Example 1: using variables in azure pipelines
variables:
GLOBAL_MYSECRET: $(mySecret) # this will not work because the secret variable needs to be mapped as env
GLOBAL_MY_MAPPED_ENV_VAR: $(nonSecretVariable) # this works because it's not a secret.
steps:
- powershell: |
Write-Host "Using an input-macro works: $(mySecret)"
Write-Host "Using the env var directly does not work: $env:MYSECRET"
Write-Host "Using a global secret var mapped in the pipeline does not work either: $env:GLOBAL_MYSECRET"
Write-Host "Using a global non-secret var mapped in the pipeline works: $env:GLOBAL_MY_MAPPED_ENV_VAR"
Write-Host "Using the mapped env var for this task works and is recommended: $env:MY_MAPPED_ENV_VAR"
env:
MY_MAPPED_ENV_VAR: $(mySecret) # the recommended way to map to an env variable
- bash: |
echo "Using an input-macro works: $(mySecret)"
echo "Using the env var directly does not work: $MYSECRET"
echo "Using a global secret var mapped in the pipeline does not work either: $GLOBAL_MYSECRET"
echo "Using a global non-secret var mapped in the pipeline works: $GLOBAL_MY_MAPPED_ENV_VAR"
echo "Using the mapped env var for this task works and is recommended: $MY_MAPPED_ENV_VAR"
env:
MY_MAPPED_ENV_VAR: $(mySecret) # the recommended way to map to an env variable
Example 2: using variables in azure pipelines
variables:
global_variable: value # this is available to all jobs
jobs:
- job: job1
pool:
vmImage: 'ubuntu-16.04'
variables:
job_variable1: value1 # this is only available in job1
steps:
- bash: echo $(global_variable)
- bash: echo $(job_variable1)
- bash: echo $JOB_VARIABLE1 # variables are available in the script environment too
- job: job2
pool:
vmImage: 'ubuntu-16.04'
variables:
job_variable2: value2 # this is only available in job2
steps:
- bash: echo $(global_variable)
- bash: echo $(job_variable2)
- bash: echo $GLOBAL_VARIABLE
