The Build Agent Home Directory is the directory where the agent is installed.
The Build Agent can be installed into any directory.
If you use the TeamCity .tar.gz distribution or .exe distribution opting to install a Build Agent, the agent will be placed into
The default directory suggested by the .exe agent installation is
The agent stores all related data under its directory and the only place that requires installation/uninstallation into an OS is integrating into the automatic start system (e.g. service settings under Windows).
The agent consists of:
- agent binaries (stored under
libdirectories). The binaries can be automatically updated from the server to match the server version.
- agent plugins and tools (stored under
toolsdirectories). These are parts of agent binary installation and are managed by the agent itself, updating automatically whenever necessary from the TeamCity server.
- agent configuration (stored under
launcher\confdirectories). This is a unique piece of information defining the agent settings and behavior.
- agent work directory (stored under the
workdirectory by default, configurable via agent configuration).
- agent auxiliary data (stored under
updatedirectories). The data necessary during agent running.
- agent logs (stored under
logsdirectory) - The directory storing internal agent logs that might be necessary for agent issues investigation.
Agent Files Modification
The agent configuration directory is the only one designed to have files that can be edited by the user.
All the other directories should not be edited by the user.
The content of the agent work directory can be deleted (but only entirely). This will result in a clean checkout for all the affected builds.
The content of directories storing agent auxiliary data can be deleted (but only entirely and while the agent is not running). Deletion of data can result in extra actions during next builds on this agent, but this is meant to have only a performance impact and should not affect consistency.
