Azure Pipeline to trigger Pipeline using YAML

Question

Attempting to trigger an Azure pipeline when another pipeline has been completed using a YAML. There\'s documentation indicating that you can add a pipeline resource with:

Answer 1

For trigger of one pipeline from another azure official docs suggest this below solution. i.e. use pipeline triggers

resources:
  pipelines:
  - pipeline: RELEASE_PIPELINE // any arbitrary name
    source: PIPELINE_NAME.    // name of the pipeline shown on azure UI portal
    trigger:
    branches:
      include:
        - dummy_branch        // name of branch on which pipeline need to trigger

But actually what happens, is that it triggers two pipelines. Take an example, let suppose we have two pipelines A and B and we want to trigger B when A finishes. So in this scenario B runs 2 times, once when you do a commit (parallel with A) and second after A finishes.

To avoid this two times pipeline run problem follow the below solution

trigger: none // add this trigger value to none 
resources:
  pipelines:
  - pipeline: RELEASE_PIPELINE // any arbitrary name
    source: PIPELINE_NAME.    // name of the pipeline shown on azure UI portal
    trigger:
    branches:
      include:
        - dummy_branch        // name of branch on which pipeline need to trigger

By adding trigger:none second pipeline will not trigger at start commit and only trigger when first finish its job.

Hope it will help.
