How to use Output Variables in Release pipeline

Question

I searched all the docs about Output Variables are for build pipeline and only told me how to set in .yaml. But how to use it in release pipeline?

Supposed I have 2 variables $abc="123" $def="456" in step Login. How to set them in below text box? and How to use them in step Deploy?

That is explained in the docs as well (learn.microsoft.com/en-us/azure/devops/pipelines/process/…) . You might have missed that there is a tab "Classic" next to "Yaml" — D.J.

I read the link. But I still don't understand. The first sentence is "Some tasks define output variables". But how to define output variables in the task Login as my question described? — Newton Zou

You don't set them in the textbox. The variables can only be defined in a custom task manifest. If you use a script task you can still set an output task, but there is no way to see them in the UI. You can rely set the reference part in the UI. — jessehouwing

Some tasks define output variables

For brief text, it represents the follow scripts:

echo "##vso[task.setvariable variable=abc;isOutput=true]123"

Just specify the reference name in the blank of task, and then, you can call this output variable abc by using the format: <reference name>.<variable name>.

For example, if you specify the reference name as mycustom, just call the output variable by using $(mycustom.abc).

Is it possible to use output variables in different agent within same pipeline?

Mengdi Liang Over a year ago

@sree1611, you are using pipeline with YAML or classic UI? If is YAML, yes , you can. If classic UI, I'm afraid you can not. You must add the output variable as a environment variable by using script, then other agents can able to access it.

Hope Release pipeline doesn't support YAML. Can you provide some example how to set environment variables ?

sree1611 Over a year ago

Environment variables are only getting updated when the release pipeline is completed. I want to use the updated variables in the same job in a different agent.
