如何自动添加（或让tfs2015发现）构建代理功能？

Question

How can I add a capability to a build agent in TFS 2015?

For example, I would like to install a build tool (on a TFS2015 build agent) and register this as a TFS Build agent capability.

I know that I can add this capability manually, through the web interface, but how to do it with a script?

I've read that TSF2015 discovers build agent capabilities alone, but.. how to instruct it about 'how to detect my build tool' ?

Answer 1

Credits go to Donovan Brown and its blog post

I have tried the solution it proposes, and it works in my scenario/environment:

1. set an environment variable during the software setup
2. this variable and its value will appear as agent capabilities in the TFS agent resume

According to a GitHub issue , this functionality will eventually appear in npm scripts accompanying vso-build-tasks.

Answer 2

In the Agent capabilities you can define custom "user capabilities" I added a custom user capability called

• "Tag" and set it to VS2015

In my build definition under General, under Demands, I added a demand that

• "Tag" equals VS2015

This will now force my build to that specific Pool (or agent)

For example I installed a 3rd Party utility to one of my build agents and added to the Agent user capabilities "AutoIt" = True. In my build, under General, Demands, I added one called "AutoIt" exists, this forces this build to the agent with the 3rd party utility that is installed.
