-# Docker Compose for Bufstream
-
-This directory contains an example `docker-compose.yml` file that sets up all required infrastructure for a [Bufstream][bufstream] environment suitable for local testing and development.
-
-## Prerequisites
-
-* [Docker][docker] must be installed. 
-* If you're using Docker Desktop, [host mode networking][docker-host-mode-networking] must be enabled.
-
-## Starting the project
-
-Just run:
-
-```
-$ docker compose up
-```
-
-## Services
-
-This Compose project will start the following services:
-
-- MinIO (https://min.io/) for S3 compatible storage.
-  * Its API endpoint is available at http://localhost:9000.
-  * Its admin endpoint is available at http://localhost:9001.
-- An AWS CLI sidecar that bootstraps an initial bucket.
-- PostgreSQL (https://www.postgresql.org/) for metadata storage.
-  * It is available on the standard Postgres port (5432).
-- A Bufstream broker.
-  * Its Kafka endpoint is available at localhost:9092.
-  * Its admin endpoint listens on its default port (9089), allowing you to run [`bufstream admin`](https://buf.build/docs/bufstream/reference/cli/admin/) commands against the broker.
-
-Note that the MinIO image is provided by [lithus](https://github.com/golithus/minio-builds). [MinIO ceased publishing public Docker images](https://github.com/minio/minio/issues/21647) in October 2025.
-
-## Memory
-
-The Compose project uses the `BUFSTREAM_AVAILABLE_MEMORY` environment variable to limit Bufstream to 1 GiB of memory.
-This should be suitable for simple local development and testing, but may be insufficient for high-throughput workloads or performance testing.
-
-If you encounter out-of-memory issues, increase the value in the `docker-compose.yml` file. For reference, production Kubernetes deployments default to 8 GiB (8589934592 bytes).
-
-## Volumes
-
-When this Compose project starts, it will create two directories:
-
-1. `minio`: A volume used by the `minio` service for object storage.
-2. `postgres`: A volume used by the `postgres` service for its database storage.
-
-Before committing this `docker-compose.yml` file to your own repository, add these to your `.gitignore`.
-
-## Networks
-
-This example uses host networking. You may encounter issues if there are port conflicts. If you need to use port mappings, see [Docker's documentation](https://docs.docker.com/compose/how-tos/networking/).

The only code changed during the tutorial is in Protobuf and YAML files, so only a Go example is provided. It contains a `start` directory with a starting state and `finish` with a working solution.
