Force TeamCity to build on a specific agent

Question

Is it possible, without disabling all other connected agents, to force TeamCity to build on a specific agents machine?

Answer 1

Under Build Configuration Settings go to Agent Requirements and set an Explicit Requirement for the specific agent name:

Parameter Name: system.agent.name

Condition: equals

Value: YOUR_SPECIFIC_AGENT_NAME

Answer 2

For one time run you can click on the 3 dots next to "Run" and define on what agent you want to run.
For a long term configuration you should use the Agent Requirements of the build.
You can add a system property to the agent by editing the file ...\buildAgent\conf\buildAgent.properties

system.special.property=true

Then you can define on the Agent Requirements to check the property system.special.property exists.

EDIT With the new version of Teamcity (5.0.*) you can now edit the Agent and select the configuration you want to run there.
Agents, select an agent, Compatible Configurations, choose "Run selected configurations only".

Answer 3

TeamCity > Administration > Agents > Select an Agent > "Compatible Configurations" tab:

Current run configuration policy: "Run assigned configurations only"

Click "+ Assign configurations"
