Running multiple TeamCity Agents on the same computer?

We have several build machines, each running a single TeamCity build agent. Each machine is very strong, and we'd like to run several build agents on the same machine.

Is this possible, without using virtualization? Are there quality alternatives to TeamCity that support this?

How do I add compatible agents in TeamCity?

Click the Agents and select the desired build agent. Click the Compatible Configurations tab. Select Run selected configurations only and tick the desired build configurations names to run on the build agent.

How do I add an agent to TeamCity pool?

To be able to add/remove pools and set maximum number of agents in the pool, you need to have the "Manage agent pools" permission granted to the System Administrator and Agent Manager roles in the default TeamCity per-project authorization mode.

Yes, it's possible:

Several agents can be installed on a single machine. They function as separate agents and TeamCity works with them as different agents, not utilizing the fact that they share the same machine. After installing one agent you can install additional one, providing the following conditions are met:

  • the agents are installed in the separate directories
  • they have distinctive work and temp directories
  • buildAgent.properties is configured to have different values for name and ownPort properties

Make sure, there are no build configurations that have absolute checkout directory specified (alternatively, make sure such build configurations have "clean checkout" option enabled and they cannot be run in parallel).

Under Windows, to install additional agents as services, modify [agent dir]\launcher\conf\wrapper.conf to change the properties to have distinct name within the computer:

  • wrapper.console.title
  • wrapper.ntservice.name
  • wrapper.ntservice.displayname
  • wrapper.ntservice.description
