I have created a pipeline in my repository which is used to validate code by executing unit tests for code that is being pushed to features/* branches. The same pipeline is used as Build validation pipeline set as Branch Policy on the develop branch to validate incoming PRs. This is the trigger of the pipeline.
# pipeline.yml
trigger:
batch: false
branches:
include:
- features/*
However we have come across the following condition: Given an open PR from refs/heads/features/azure-pipelines -> refs/heads/develop we push a commit on the features/azure-pipelines branch.
This causes the pipeline to trigger twice. To my understanding one of the runs is due to the trigger of the pipeline (The one marked as Individual CI on the screenshot) and the second run is due to branch policy trying to validate code being pushed onto the open PR to develop. (The PR Automated)
Is there any way to disable one of the executions since it's essentially a duplicate? I was maybe looking for a way to retrieve open PRs and abort execution of a pipeline for Individual CI if there is an open PR for a branch but I am not sure that's the best way around that and I am looking for options.
You can set
trigger: none
This way only the branch policy will trigger the pipeline.
Is there any way to disable one of the executions since it's essentially a duplicate?
As we know, we could not disable the Build validation pipeline set as Branch Policy on the develop branch to validate incoming PRs unless we cancel the Build validation.
For your situation, you could try to include [skip ci] in the commit message or description of the HEAD commit to make the Azure Pipelines skip running CI when you plan to merge the features branch to the develop branch.
You could check the document Skipping CI for individual commits for some more details.
Here it depends if they does the same. You can have conditional checks in the pipeline which does a different things for PR and CI runs. However, I'm pretty sure that this is not possible, because one is defined on the YAML and the second on the Azure DevOps portal. So even if you disnle PR trigger here in YAML, a branch policy still runs a PR. And you can specify antyhing in YAML to block branch policy.

How do we create multi branch pipeline in azure.
Say there are 4 developers committing to the same branch, for each commit there should be a seperate build pipeline with unit tests.
for each commit there should be a seperate build pipeline with unit tests.
If you want to have a seperate build pipeline with unit tests for each commit, you need to create multi pipeline for each branch:
And if just want to one build pipeline for those multi branch, you may need to have create multi branch triggers:
I think what you need is a CI pipeline. So lets say, there is a main/master branch, 4 developers have pulled this main branch in their PC/laptop. And all 4 of them are about to work on 4 different defects/bugs say bug1,Bug2, Bug3 and Bug4
Each one of them are supposed to create a branch from main. Say bug/Bug1, bug/Bug2, bug/Bug3 and bug/Bug4. So now we got 4 branches.
What you can do now is switch on pull request branch policies in main branch. Please see below screenshot
Once you switch on this pull request policy, no code can be merged in your main branch without creating a pull request.
Now second part, you have to create a pipeline that will for example, build the code and run some tests.
Now part three: In the same branch policies page, if you scroll down a bit, you will see a setting for "Build Validation" as shown below
What you have to do here is
Press that + sign and configure the pipeline that you have created earlier here.
What this means is
When say Dev 1 whose branch is bug/Bug1 will raise a pull request to merge in main branch, this Build validation will trigger the pipeline that you have configured here.
So when all 4 Devs will raise 4 pull requests, based on their code changes, this pipeline will get triggered and validate those code changes for build + tests.
Also, based on the code review, if there are any further code changes pushed into these branches (bug/Bug1 etc.), you can configure this Build validation in such a way that this pipeline will get automatically triggered whenever new code changes are pushed into a branch which is connected to a pull request.
I have a Question about the Pipline trigger in Devops.
My team and I are using Azure Devops to develop a software.
We use a Branch Specific trigger, to start the pipeline only in out Master Branch. The other branches are ignored in the YAML File.
First part of my question is, that we don't know a way how to trigger the Pipeline over a commit message in our Git tool.
For example: "We work in a different branch than the Master branch -->No Pipeline is running. But we want to trigger the pipeline in this Branch for a Specific test just one time. Our way would be to insert a specific command in the commit text to trigger the pipeline."
My second question is, if it's possible to run different stages in different Branches in one YAML file.
Here again an example: " In our different Branch, we just want to run our unit tests every push. In our Master Branch we want to run our unit tests and after that, we want to build our application.
So far, we started the pipeline at every push and build a new image everytime. But we dont want that, because some pushs arent working and we just push it. We want to decide when the pipeline is running and whitch stage is running.
I hope you can understand my problem. For further questions, please comment here.
Thanks
Question 1:
You can consider using tag triggers to do this. Here is an example:
trigger:
branches:
include:
- master
tags:
include:
- test.*
Then the pipeline will be triggered when working on the master branch or the commit tag is test.*.
Question 2:
You can use conditions. Here is an example:
condition: and(succeeded(), eq(variables['Build.SourceBranch'], 'refs/heads/master'))
Add the condition to your stage, and then the stage will be only triggered by the master branch.
Question 3:
So far, we started the pipeline at every push and build a new image everytime. But we dont want that, because some pushes aren't working and we just push it.
You can skip CI for individual commits.
Just include [skip ci] in the commit message or description of the
HEAD commit and Azure Pipelines will skip running CI.
Update 1:
For Question 1, the test.* means a tag which started with test., such as test.1, test.0.1, and so on. You can change the test.* to anything you want.
As for the question your encountered, you can't create a tag called test.* directly because a tag name cannot contain *.
To avoid confusion, you need to create a tag for the commit to trigger the tag CI, rather than writing it directly in the commit text.
The idea
insert a specific command in the commit text to trigger the pipeline.
I don't think is currently supported and tag trigger is an alternative.

Update 2:
Trigger the stage by master branch or 1620-to-PipelineTrigger branch:
condition: or(eq(variables['Build.SourceBranch'], 'refs/heads/main'), eq(variables['Build.SourceBranch'], 'refs/heads/1620-to-PipelineTrigger'))
You can set only one condition per stage, but you can create more complex conditions using and, or and ().

I have a .Net project that uses the Azure DevOps pipelines. The setup is that I have a build pipeline that creates an artifact. The artifact then automatically gets published through the release pipeline. This is working perfectly.
The problem is after I turned on the policy Build Validation, pull requests now triggers the build pipeline which then triggers the release pipeline. So every pull requests gets published. The build step is correct, but the release should not happen. The pre-deployment trigger "Pull request deployment" is disabled.
What I did to try to solve this is that I added a condition to the build step where the artifact gets created. So pull requests does not create artifacts, while merges does. This also works as intended. However, the release pipe still gets triggered, but this time without an artifact (which fails the pipe).
TLDR:
Release pipe triggers on pull requests, settings for this behavior is off. WTD?
My CI/CD settings:
Your release triggers on any of your builds and branches (PR also has a branch). You have to add the branch filter: Continuous deployment triggers. Restrict your filter with the master branch or any other. Also, you can define 2 build definitions:
A pipeline to validate your pull requests without linked releases.
CI pipeline that triggers a release.
Additionally, I think, this is a bug. Because the PR trigger is not enabled. Let's check dev community comments: https://developercommunity.visualstudio.com/content/problem/1292039/release-pipelines-ignore-pull-request-settings.html
What we have here is that we've set up build pipelines tied to YAML files stored in the repository, together with source code. And release pipelines have their Source set up to each of the build pipelines.
This is part of the Master Build:
trigger:
batch: false
branches:
include:
- master
And this is part of the Pull Request Build:
trigger: none
pr:
- master
We have Release pipelines for each of the Source builds, having Pull Request triggers enabled in one of them only, but you can have only one for your master artifacts, so PRs won't be published.
I have a use case where I have two pipelines configured. One for running tests which are triggered by a Pull Request and another pipeline that is handling deployment. I am using Bitbucket cloud in Azure.
Pipeline A - Run through tests on PR.
Pipeline B - Deploy upon successful merge (approved pull request).
My current setup is to trigger pipeline A when a pull request is submitted. This is no problem and works as intended. The issue I am running into is with Pipeline B. It is triggered regardless of whether the PR is approved or even merged. I know that expected behavior for the CI trigger is to fire off with any action on the branch. The PR trigger also doesn't fit my needs though as it would be redundant with Pipeline A.
What I would like to happen is since Pipeline A fires off on PR, a code reviewer will Approve and Merge the PR and only if the PR ends up getting merged into the Release branch is Pipeline B triggered. Is this possible?
Developer completes code.
Developer submits PR against a Release1.0 branch.
Pipeline A triggers. Tests pass or fail.
Code reviewer approves and merges PR into Release1.0 branch.
Pipeline B triggers and deploys.
UPDATE: For those who bump into the same issue it's actually quite a simple fix. Simply setting the trigger...
pr: none
in Pipeline B will do the trick.
To be clear, this solution is specific to Bitbucket Cloud and GitHub repositories only. The 'pr' syntax in YAML pipelines doesn't exist for Azure Repositories (use branch policy instead).
Azure DevOps Release pipeline artifact settings has 2 options:
Continuous deployment trigger - Enabling the trigger will create a new release every time a new build is available.
Pull request trigger - Enabling this will create a release every time a selected artifact is available as part of a pull request workflow
I am trying to understand what is the difference between these options with respect to the highlighted parts and whether the build validation policy causes release to trigger with both options, if so then why do we have pull request trigger?
In my opinion, these two triggers have different working scope.
Assuming we set one CI build as release artifact, according to my test:
1.Continuous deployment trigger:
Whenever we have a new version of the Build, it triggers the release. It means that no matter the build pipeline is triggered by manual run, CI trigger or build validation in branch policy, the release is triggered when there's one newer build.
2.Pull request trigger:
It has a smaller scope, it will be trigger by the build pipeline which is trigger by build validation in branch policy.
(Which is triggered by PR, so if we create new PR=>It triggers PR build=>It triggers PR release)
Feel free to correct me if I misunderstand anything.
Update1:
Here's one pic about my two tests:
Release-8 is triggered by my manual running Build pipeline with only CD triggered enabled. And Release-7 is triggered by PR build with only PR triggered enabled. (I only enable the Pull Request for deployment in Stage 1)
Apart from working scope, these two triggers also have a little difference here. The Pull Request Deployment in stage for now is only for PR trigger in Artifact.
This explains that very well (taken from documentation):
Pull requests (PRs) provide an effective way to have code reviewed
before it is merged to the codebase. However, certain issues can be
tricky to find until the code is built and deployed to an environment.
Before the introduction of pull request release triggers, when a PR
was raised, you could trigger a build, but not a deployment. Pull
request triggers enable you to create pull request releases that
deploy your PR code or PR builds to detect deployment issues before
the code changes are merged. You can use pull request triggers with
code hosted on Azure Repos or GitHub.
New build basically means that your pipeline was executed.
Creating pull request trigger you need to define an artifact which will be later deployed. For this kind of trigger Azure Devops runs your pipeline and produce artifact according to your pipeline/build definition and later use this artifact for deployment.
Both trigger are similar, the difference is when your code will be deployed before or after being merged into main branch.
PR trigger is part of CI - applies when your merge your branch to master
CD trigger - applies only to the master branch
