Volumes & Storage

Docker Swarm volumes are local to each node — they do not replicate across servers. Losing a node means losing its volumes unless backed up.

`dev_postgresql_data`	DEV PostgreSQL (Primary)	Yes — all DEV application data
`dev_postgresql_replica_data`	DEV PostgreSQL (Replica)	Medium — read-only copy of primary
`dev_redis_data`	DEV Redis	No — cache, regenerates
`dev_rabbitmq_data`	DEV RabbitMQ	Medium — queued messages

Checking Volume Usage

# List all volumes
docker volume ls

# Inspect a volume (shows mount point)
docker volume inspect dev_postgresql_data

# Check disk usage on the server
df -h
