# ./buildserver_pgdata - Posgres DB data
# ./data_dir - TeamCity data directory
# ./log_dir - logs of primary TeamCity server
# ./agents/agent-1/conf - configuration directory for the first build agent
# ./agents/agent-1/conf - configuration directory for the second build agent

buildAgent.properties

name=Agent
ownPort=9090
serverUrl=http\://localhost\:8112

workDir=../work
tempDir=../temp
systemDir=../system

teamcity.docker.use.sudo=true

NOTE:- I have tried with both (8111, 8112) PORTS inside my buildAgent.propeties
