TeamCity docker-compose multi-node sample

Starts TeamCity in docker-compose with several servers of different roles (Ubuntu-based).

Requires at least 4Gb of RAM in the docker engine.

• Uses Postgres DB (psql -p5433 -hlocalhost -Uuser -dbuildserver, password password)
• Starts 3 server: primary, running-builds node, secondary node.
• And, 3 build agents

For details on volumes, created folders, logs see docker-compose.yml file.

To start

docker-compose up

Next, open http://localhost:8111 for the initial setup.

After creating a user, visit "Agents -> Unauthorized" to authorize the build agent.

See https://localhost:8111/admin/admin.html?item=nodesConfiguration for nodes configuration.

To shutdown

docker-compose down
