Configuring Build Agent Startup Properties
In TeamCity a build agent contains two processes:
Agent Launcher – a Java process that launches the agent process
Agent – the main process for a Build Agent; runs as a child process for the agent launcher Whether you run a build agent via the
agent.bat|shscript or as a Windows service, at first the agent launcher starts and then it starts the agent.
Agent Properties
For both processes above you can customize the final agent behavior by specifying system properties and variables for the agent to run with.
