This is an official JetBrains TeamCity build agent image. The TeamCity build agent connects to the TeamCity server and spawns the actual build processes. You can use the jetbrains/teamcity-server image to run a TeamCity server. This image adds a TeamCity agent suitable for Java development. It is based on jetbrains/teamcity-minimal-agent but gives you more benefits, e.g. client-side checkout if you use 'git' or 'mercurial' more bundled build tools 'docker-in-docker' on Linux
