参数中的 Azure DevOps 条件

Question

Help me please with creating conditions in parameters in the step template.

I want to change parameters in the template depending on variable.Mode value. For example, this code doesn't work:

  - template: ../templates/template1.yml
    parameters:
      ${{ if eq(variables.Mode, 'dev') }}:
        mode: dev
        namespace: dev-namespace
        fqdn: dev.mysite.com
      ${{ if eq(variables.Mode, 'staging') }}:
        mode: staging
        namespace: staging-namespace
        fqdn: staging.mysite.com
        anothervar: value
        yetanothervar: value2

The template executes with default values of parameters. What can I do to set vars depending on variable.Mode value.

You can specify different parameter values in stages. Here is my sample:

azure-pipelines.yml:

variables:
  Mode: dev

stages:
  - ${{ if eq(variables.Mode, 'dev') }}:
    - template: template.yml
      parameters:
        mode: dev
        namespace: dev-namespace
        fqdn: dev.mysite.com

  - ${{ if eq(variables.Mode, 'staging') }}:
    - template: template.yml  # Template reference
      parameters:
        mode: staging
        namespace: staging-namespace
        fqdn: staging.mysite.com
        anothervar: value
        yetanothervar: value2 

template.yml:

parameters:
- name: mode  
  default: ''
- name: namespace
  default: ''
- name: fqdn
  default: ''
- name: anothervar 
  default: ''
- name: yetanothervar 
  default: ''

stages:
- stage: 
  jobs:
  - job: 
    steps:
    - script: echo ${{ parameters.mode }}
