Usage

Running DevServices

docker compose up -d

This command will run the default services. See Profiles for information on how to run additional services.

Default Services:

• Kafka in KRaft mode
• Schema Registry
• AKHQ

Profiles

If you want to run other services in addition to the default ones, simply add the respective profile.

Profile	Containers
ktb	Kafka Topology Builder
kafka-extended	Additional Kafka Services
s3	MinIO S3 bucket storage
postgres	Postgres Database
mssql	MSSQL Database

Example:

docker compose --profile mssql up -d

To run multiple profiles use multiple --profile flags:

docker compose --profile s3 --profile mssql up -d

Stopping DevServices

docker compose down -v

Remember to also add the profiles used in the up command to your down command, e.g. docker compose --profile mssql down -v

⚠️ Adding the -v flag will delete all volumes created by DevServices. If you want to persist the data in the databases and MinIO S3 buckets, remove the -v flag from the command.
