Dropdown or Radio button options in Azure Devops:-

Greetings to my fellow Technology Advocates and Specialists.

In this Session, I will demonstrate Dropdown OR Radio button options in Azure Devops.

AUTOMATION OBJECTIVES:-

#	TOPICS
1.	Radio Button option as Runtime Variables in Azure Devops Pipelines.
2.	Dropdown Menu option as Runtime Variables in Azure Devops Pipelines.
3.	Spot the difference.

IMPORTANT NOTE:-

The YAML Pipeline is tested on WINDOWS BUILD AGENT Only!!!

REQUIREMENTS:-

1. Azure Subscription.
2. Azure DevOps Organisation and Project.
3. Service Principal with Required RBAC ( Contributor) applied on Subscription or Resource Group(s).
4. Azure Resource Manager Service Connection in Azure DevOps.

HOW DOES MY CODE PLACEHOLDER LOOKS LIKE:-

1. RADIO BUTTON OPTION AS RUNTIME VARIABLES:-

PIPELINE CODE SNIPPET:-

AZURE DEVOPS YAML PIPELINE (azure-pipelines-runtime-parameter-options-v1.0.yml):-

trigger:
  none

##################
# Radio Button:-
##################
parameters:
  - name: environment
    displayName: Select environment
    type: string
    default: 'dev'
    values:
      - dev
      - test
      - uat

#############
#Variables:-
############
variables:
  ServiceConnection: 'amcloud-cicd-service-connection' # Please replace with your Service Connection!
  BuildAgent: 'windows-latest' # Please replace with your Build Agent. You can continue to use this as this is Microsoft Hosted Windows Build Agent!

######################
# Declare Build Agent:-
######################
pool:
  vmImage: '$(BuildAgent)'

##################################
# Declare Stages:-
# Test Runtime parameters as:-
# 1. Radio Button
##################################
stages:
- stage: Test_Runtime_Parameters_RadioButton
  displayName: Test Runtime Parameters Radio Button
  jobs:
  - job: Test_Runtime_Parameters_RadioButton
    steps:
    - task: AzureCLI@2
      displayName: Test Runtime Parameters RadioButton
      inputs:
        azureSubscription: '$(ServiceConnection)'
        scriptLocation: 'inlineScript'
        scriptType: 'ps'
        inlineScript: |
          echo "Deploying to ${{ parameters.environment }} environment"

CODE BLOCK FOR RADIO BUTTON AS RUNTIME VARIABLES IN YAML:-

##################
# Radio Button:-
##################
parameters:
  - name: environment
    displayName: Select environment
    type: string
    default: 'dev'
    values:
      - dev
      - test
      - uat

OUTPUT: RADIO BUTTON OPTION AS RUNTIME VARIABLES
1. Radio Button as runtime variables is displayed successfully on Pipeline Execution.
2. Successful Pipeline Execution.

2. DROPDOWN MENU OPTION AS RUNTIME VARIABLES:-

PIPELINE CODE SNIPPET:-

AZURE DEVOPS YAML PIPELINE (azure-pipelines-runtime-parameter-options-v1.1.yml):-

trigger:
  none

##################
# Drop Down Menu:-
##################
parameters:
  - name: environment
    displayName: Select environment
    type: string
    default: 'dev'
    values:
      - dev
      - test
      - uat
      - prod

#Variables:-

variables:
  ServiceConnection: 'amcloud-cicd-service-connection' # Please replace with your Service Connection!
  BuildAgent: 'windows-latest' # Please replace with your Build Agent. You can continue to use this as this is Microsoft Hosted Windows Build Agent!

##################################
# Declare Stages:-

# 1. Dropdown Menu
##################################
stages:
- stage: Test_Runtime_Parameters_DropDown_Menu
  displayName: Test Runtime Parameters Dropdown Menu
  jobs:
  - job: Test_Runtime_Parameters_DropDown_Menu
    steps:
    - task: AzureCLI@2
      displayName: Test Runtime Parameters Dropdown Menu
      inputs:
        azureSubscription: '$(ServiceConnection)'
        scriptLocation: 'inlineScript'
        scriptType: 'ps'
        inlineScript: |
          echo "Deploying to ${{ parameters.environment }} environment"

CODE BLOCK FOR DROPDOWN MENU AS RUNTIME VARIABLES IN YAML:-

##################
# Drop Down Menu:-
##################
parameters:
  - name: environment
    displayName: Select environment
    type: string
    default: 'dev'
    values:
      - dev
      - test
      - uat
      - prod

OUTPUT: DROPDOWN MENU OPTION AS RUNTIME VARIABLES
1. Dropdown Menu as runtime variables is displayed successfully on Pipeline Execution.
2. Successful Pipeline Execution.

3. SPOT THE DIFFERENCE:-
The "type" of the variable is exactly the same except the no. of values. For "Radio button", we entered 3 values but if we needed "Dropdown Menu", we just increased 1 more value. "Radio button" option changes to "Dropdown Menu".
For "Radio button", value count <= 3
For "Dropdown Menu", value count > 3

Hope You Enjoyed the Session!!!
