Azure DevOps Release pipeline using build tags

Question

I'm trying to understand how the option Build tags works inside the Continuous deployment trigger of the release pipeline.

build tags

Here I can add Build tags, in my build pipeline is set the following build tags: $(Build.DefinitionName)_$(Build.BuildNumber) But when I put the same inside the build tags at the Release pipeline. It won't do anything.

The tag's are succesfully added: tag

What I'm trying to archive is that when a build is successful a tag is created and the release pipline is triggered when the tag is the same as the one I set after the build.

Is this how it should work, or do I mix thing up?

Answer 1

It is doing an exact name match of the build tag. If you wanted this to work, you'd need to put the hard-coded build number. Not the template for creating the build number.

For my product, we build in both debug and release configurations. I will stamp a tag either { debug, release}. Then on the release pipeline, you might have the build tag only flagged for { release }, so you don't ever deploy debug copies.
