Remarks

In Azure DevOps Server 2019 you can specify a pool at the job level in YAML, and at the pipeline level in the pipeline settings UI. In Azure DevOps Server 2019.1 you can also specify a pool at the pipeline level in YAML if you have a single implicit job.

You can specify a pool at the pipeline, stage, or job level.

The pool specified at the lowest level of the hierarchy is used to run the job.

Remarks

Specify a Microsoft-hosted pool using the vmImage property.

If your self-hosted agent pool name has a space in it, enclose the pool name in single quotes, like name: 'My pool'.

Examples

To use a Microsoft-hosted pool, omit the name and specify one of the available hosted images:

pool:
  vmImage: ubuntu-latest

You can specify demands for a private pool using the full syntax.

To add a single demand to your YAML build pipeline, add the demands: line to the pool section.

pool:
  name: Default
  demands: SpecialSoftware # exists check for SpecialSoftware

Or if you need to add multiple demands, add one per line.

pool:
  name: MyPool
  demands:
  - myCustomCapability   # exists check for myCustomCapability
  - Agent.Version -equals 2.144.0 # equals check for Agent.Version 2.144.0

Note

Checking for the existence of a capability (exists) and checking for a specific string in a capability (equals) are the only two supported operations for demands.

For more information and examples, see Specify demands.
