Summary
This PR adds the initial scaffolding to run DeltaFS as multiple isolated “DISA-style” nodes locally using Docker. Nodes communicate over a protobuf + gRPC API, making it possible to test distributed behavior (multi-node RPC, node isolation, and basic lifecycle operations) without needing multiple machines.
What’s included
• Docker-based node isolation to run multiple DeltaFS nodes side-by-side.
• Protobuf definitions + gRPC service wiring to establish the RPC contract between nodes.
• A minimal local cluster configuration to bring up nodes and verify connectivity.
Why this change
The main goal is to create a reliable local environment to experiment with distributed systems concepts inside DeltaFS (replication, journaling, snapshot management, and recovery) while keeping node boundaries realistic via containers.
How to test
• Bring up the local cluster (Docker) and confirm that all nodes start successfully.
• Use the included RPC endpoints or simple health/status calls to verify node-to-node communication.
Follow-ups / future work
• Implement replication primitives (leader/follower or primary-backup) on top of this RPC layer.
• Add journal manager + snapshot manager services.
• Add a Kubernetes deployment option (kind/minikube) once the Docker workflow is stable.
