4.2 Multi-Node Cluster

For production deployments across multiple physical/virtual machines, use Docker Swarm:

Initialize Swarm:

# On manager node
docker swarm init --advertise-addr <MANAGER-IP>

# On worker nodes
docker swarm join --token <TOKEN> <MANAGER-IP>:2377

Deploy stack:

4.3 Volume Management

Named Volumes (recommended for production):

# Create volumes
docker volume create --driver local \
  --opt type=none \
  --opt o=bind \
  --opt device=/mnt/data/metadata-1 \
  metadata-1-data

docker volume create --driver local \
  --opt type=none \
  --opt o=bind \
  --opt device=/mnt/data/storage-1 \
  storage-1-data

Volume Backup:

# Backup volume
docker run --rm \
  -v storage-1-data:/data \
  -v /backup:/backup \
  alpine tar czf /backup/storage-1-backup-$(date +%Y%m%d).tar.gz -C /data .

# Restore volume
docker run --rm \
  -v storage-1-data:/data \
  -v /backup:/backup \
  alpine tar xzf /backup/storage-1-backup-20251101.tar.gz -C /data

4.4 Network Configuration

Custom Bridge Network:

# Create custom network
docker network create \
  --driver bridge \
  --subnet 172.20.0.0/16 \
  --gateway 172.20.0.1 \
  --opt "com.docker.network.bridge.name"="heliosdb0" \
  --opt "com.docker.network.bridge.enable_icc"="true" \
  heliosdb-net

DNS Configuration:

# docker-compose.yml additions
services:
  metadata-1:
    dns:
      - 8.8.8.8
      - 8.8.4.4
    dns_search: heliosdb.local
    extra_hosts:
      - "metadata-1.heliosdb.local:172.20.0.10"
      - "storage-1.heliosdb.local:172.20.0.20"
