Docker Compose Reference

Base sandbox compose

docker-compose.yml is the public local sandbox and observability stack.

Core services include:

• astra-node1, astra-node2, astra-node3
• minio, minio-init
• traffic-gen
• prometheus, grafana

Production-adjacent compose assets

The repo also ships compose overlays for the Astra-backed single-node K3s path:

• refs/scripts/deploy/docker-compose.k3s-single-node.production.yml
• refs/scripts/deploy/docker-compose.k3s-single-node.object-store.yml
• refs/scripts/validation/docker-compose.image.yml

Important rule:

• the validation compose defaults are benchmark-oriented,
• the production single-node overlays are the right starting point for real K3s+Astra deployments.

For parameter-level runtime tuning, use /reference/config/env-vars.
