Azure DevOps YAML: Conditional template call

Question

I want to check if Fetch_Commits succeeded in order to run jobs in microservice-calls.yaml file. I don't want to use Stages since there are no semantic for separating among jobs.

Are there any similar syntax to

- ${{ if succeeded('Fetch_Commits') }}:
     - template: templates/microservices-calls.yaml

The YAML file:

trigger:
- trigger-branch

jobs:
    - job: Fetch_Commits
      displayName: Checkout
      pool:
       name: MyPool
      steps:
      - checkout: self
        fetchDepth: 2
    - ${{ if succeeded('Fetch_Commits') }}:
      - template: templates/microservices-calls.yaml

In Azure Pipelines, dependsOn and condition cannot be used directly in template references. So, these properties need to be set on every job inside the template. If your templates/microservices-calls.yaml file contains multiple jobs, you need to set dependsOn and condition separately in each job. Assume your microservices-calls.yaml is as follows:

#  templates/microservices-calls.yaml
jobs:
- job: Microservice_Job_1
  dependsOn: Fetch_Commits
  condition: succeeded('Fetch_Commits')
  steps:
  - script: echo Running Microservice Job 1

- job: Microservice_Job_2
  dependsOn: Fetch_Commits
  condition: succeeded('Fetch_Commits')
  steps:
  - script: echo Running Microservice Job 2

Then you can use the template as the following yaml. Microservice_Job will only run when the Fetch_Commits job succeeds.

trigger:
- trigger-branch

jobs:
  - job: Fetch_Commits
    displayName: Checkout
    pool:
      name: MyPool
    steps:
    - checkout: self
      fetchDepth: 2

  - template: templates/microservices-calls.yaml
