Deploy a Azure Pipelines agent on Linux - Azure Pipelines
Note In Microsoft Team Foundation Server (TFS) 2018 and previous versions, run and release pipelines are called definitions, runs are called builds, service connections are called service endpoints, stages are called environments, and jobs are called phases. To run your jobs, you'll need at least one agent.
