Set environment variables into azure devops pipelines step from template - azure-devops

Question

Given I have following step in Azure Devops pipeline:
- task: DotNetCoreCLI#2
displayName: Run tests
inputs:
command: "test"
env:
"ASPNETCORE_ENVIRONMENT": "test"
"Case_sensitive_environment_variable_key": "This is the value"
I'd like to move this step into the template and enable users of that template to pass in env key values making sure it keeps case sensitivity of keys and values.
How can I do that?

Answer 1

According to your description and to transfer the parameter as the environmental varailbles on the level of a task, you may try Passing parameters into the template and using the parameter type of object.
Kindly take the following main YAML pipeline and template.yml for a reference.
Main
trigger: none
parameters:
- name: pEnvironment
type: object
default:
ASPNETCORE_ENVIRONMENT: "TEST 1"
Case_sensitive_environment_variable_key: "This is the value 1"
pool:
vmImage: windows-latest
stages:
- stage:
jobs:
- template: Templates/template1.yml
parameters:
transferedEnv: ${{ parameters.pEnvironment }}
Template
parameters:
- name: transferedEnv
type: object
jobs:
- job:
steps:
- task: DotNetCoreCLI#2
displayName: Run tests
inputs:
command: "test"
env:
${{ parameters.transferedEnv }}
When we run the main pipeline, we can input as well the values of the env to transferred into the template.
