From this link it appears that Agents have been renamed to Pipelines. https://www.visualstudio.com/en-us/docs/setup-admin/team-services/get-more-build-or-load-testing-vs
It also states that "Private agents are now free and unlimited." From Build & Release, Resource Limits, I show one free Pipeline.
We tried to add a second private agent to our VSTS and received the error:
"No more private agent slots available, please purchase more. For more information visit: https://go.microsoft.com/fwlink/?LinkID=623705 Current max: 1 Xaml Controllers: 0 Build Agents: 1"
From the link above it'd appear we did what we needed to do and should be able to add aditional agents. Any idea why we can't add an additional agent and Current max is 1?
We have not switched from the agent-based model to pipeline model yet in Team Services. As we are still in the agent-based model, you will see this error if you have not purchased enough agents. We plan to switch to the pipeline model late January or early February.
Thanks for reporting this. It looks like there is a problem with the logic so the engineering feature team is going to deploy a fix that should fix this problem. You are right: you can have unlimited agents and concurrent pipelines is what we are transitioning to charging for where pipelines can leverage multiple agents if needed.
