+# HugeGraph Docker Deployment
+
+This directory contains Docker Compose files for running HugeGraph:
+
+| File | Description |
+|------|-------------|
+| `docker-compose.yml` | Single-node cluster using pre-built images from Docker Hub |
+| `docker-compose-dev.yml` | Single-node cluster built from source (for developers) |
+| `docker-compose-3pd-3store-3server.yml` | 3-node distributed cluster (PD + Store + Server) |
+
+## Prerequisites
+
+- **Docker Engine** 20.10+ (or Docker Desktop 4.x+)
+- **Docker Compose** v2 (included in Docker Desktop)
+- **Memory**: Allocate at least **12 GB** to Docker Desktop (Settings → Resources → Memory). The 3-node cluster runs 9 JVM processes (3 PD + 3 Store + 3 Server) which are memory-intensive. Insufficient memory causes OOM kills that appear as silent Raft failures.
+
+> [!IMPORTANT]
+> The 12 GB minimum is for Docker Desktop (Mac/Windows). On Linux with native Docker, ensure the host has at least 12 GB of free memory.
+
+> [!WARNING]
+> **Temporary workaround — source clone currently required.** The `docker-compose.yml` (quickstart) and `docker-compose-3pd-3store-3server.yml` compose files currently mount entrypoint scripts directly from the source tree because the published Docker Hub images do not yet include the updated entrypoints. This means these compose files currently require a full repository clone to run. This requirement will be removed in a follow-up image release once updated images are published to Docker Hub with the new entrypoints baked in. The `docker-compose-dev.yml` (dev build) is unaffected since it builds images from source.
+
+## Why Bridge Networking (Not Host Mode)
+
+Previous versions used `network_mode: host`, which only works on Linux and is incompatible with Docker Desktop on Mac/Windows. The cluster now uses a proper Docker bridge network (`hg-net`) where services communicate via container hostnames (`pd0`, `pd1`, `store0`, etc.) instead of `127.0.0.1`. This makes the cluster portable across all platforms.
+
+---
+
+## Single-Node Setup
+
+Two compose files are available for running a single-node cluster (1 PD + 1 Store + 1 Server):
+
+### Option A: Quick Start (pre-built images)
+
+Uses pre-built images from Docker Hub. Best for **end users** who want to run HugeGraph quickly.
+
+```bash
+cd docker
+docker compose up -d
+```
+
+- Images: `hugegraph/pd:latest`, `hugegraph/store:latest`, `hugegraph/server:latest`
+- `pull_policy: always` — always pulls the latest image
+- PD healthcheck endpoint: `/` (root)
+- Single PD, single Store (`HG_PD_INITIAL_STORE_LIST: store:8500`), single Server
+- No `STORE_REST` or `wait-partition.sh` — simpler startup
+
+### Option B: Development Build (build from source)
+
+Builds images locally from source Dockerfiles. Best for **developers** who want to test local changes.
+
+```bash
+cd docker
+docker compose -f docker-compose-dev.yml up -d
+```
+
+- Images: built from source via `build: context: ..` with Dockerfiles
+- No `pull_policy` — builds locally, doesn't pull
+- Entrypoint scripts are baked into the built image (no volume mounts)
+- PD healthcheck endpoint: `/v1/health`
+- Otherwise identical env vars and structure to the quickstart file
+
+### Key Differences
+
+| | `docker-compose.yml` (quickstart) | `docker-compose-dev.yml` (dev build) |
+|---|---|---|
+| **Images** | Pull from Docker Hub | Build from source |
+| **Who it's for** | End users | Developers |
+| **pull_policy** | `always` | not set (build) |
+
+**Verify** (both options):
+```bash
+curl http://localhost:8080/versions
+```
+
+---
+
+## 3-Node Cluster Quickstart
+
+```bash
+cd docker
+docker compose -f docker-compose-3pd-3store-3server.yml up -d
+```
+
+**Startup ordering** is enforced via `depends_on` with `condition: service_healthy`:
+
+1. **PD nodes** start first and must pass healthchecks (`/v1/health`)
+2. **Store nodes** start after all PD nodes are healthy
+3. **Server nodes** start after all Store nodes are healthy
+
+This ensures Raft leader election and partition assignment complete before dependent services attempt connections.
+
+**Verify the cluster is healthy**:
+
+```bash
+# Check PD health
+curl http://localhost:8620/v1/health
+
+# Check Store health
+curl http://localhost:8520/v1/health
+
+# Check Server (Graph API)
+curl http://localhost:8080/versions
+
+# List registered stores via PD
+curl http://localhost:8620/v1/stores
+
+# List partitions
+curl http://localhost:8620/v1/partitions
+```
+

+## Troubleshooting
+
+### Containers Exiting or Restarting (OOM Kills)
+
+**Symptom**: Containers exit with code 137, or restart loops. Raft logs show election timeouts.
+
+**Cause**: Docker Desktop does not have enough memory. The 9 JVM processes require at least 12 GB.
+
+**Fix**: Docker Desktop → Settings → Resources → Memory → set to **12 GB** or higher. Restart Docker Desktop.
+
+```bash
+# Check if containers were OOM killed
+docker inspect hg-pd0 | grep -i oom
+docker stats --no-stream
+```
+
+### Raft Leader Election Failure
+
+**Symptom**: PD logs show repeated `Leader election timeout`. Store nodes cannot register.
+
+**Cause**: PD nodes cannot reach each other on the Raft port (8610), or `HG_PD_RAFT_PEERS_LIST` is misconfigured.
+
+**Fix**:
+1. Verify all PD containers are running: `docker compose -f docker-compose-3pd-3store-3server.yml ps`
+2. Check PD logs: `docker logs hg-pd0`
+3. Verify network connectivity: `docker exec hg-pd0 ping pd1`
+4. Ensure `HG_PD_RAFT_PEERS_LIST` is identical on all PD nodes
+
+### Partition Assignment Not Completing
+
+**Symptom**: Server starts but graph operations fail. Store logs show `partition not found`.
+
+**Cause**: PD has not finished assigning partitions to stores, or stores did not register successfully.
+
+**Fix**:
+1. Check registered stores: `curl http://localhost:8620/v1/stores`
+2. Check partition status: `curl http://localhost:8620/v1/partitions`
+3. Wait for partition assignment (can take 1–3 minutes after all stores register)
+4. Check server logs for the `wait-partition.sh` script output: `docker logs hg-server0`
+
+### Connection Refused Errors
+
+**Symptom**: Stores cannot connect to PD, or Server cannot connect to Store.
+
+**Cause**: Services are using `127.0.0.1` instead of container hostnames, or the `hg-net` bridge network is misconfigured.
+
+**Fix**: Ensure all `HG_*` env vars use container hostnames (`pd0`, `store0`, etc.), not `127.0.0.1` or `localhost`.
