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?

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
