## Context
When deploying a multi-node Qdrant cluster with docker-compose / swarm / kubernetes, the initial cluster topology (bootstrap, peer URIs) could only be passed as CLI flags (--bootstrap, --uri), not configured in config.yaml, making containerized scaling awkward.

## Verified resolution
Implemented by maintainer timvisee: cluster bootstrap/topology configuration in the config file shipped first in the qdrant/qdrant:dev image and then in stable Qdrant 1.13.3. Reporter confirmed 'it works like a charm'. Closed as completed.
