is_database() compared the whole repository part of the image reference against postgres, mariadb, redis, memcached and mongo. Every reference with a registry or namespace prefix, every derivative image and every locally built `<engine>_custom` image therefore counted as application data and went to the mass storage. On a local stack the central databases report `postgres_custom:18` and `openldap_custom:13.7-slim`, both classified False and moved to the HDD. The check now takes the last path component of the reference, drops digest, tag and a `_custom` suffix, and compares it against the engines the svc-db-* providers and the app-local databases run: elasticsearch, mariadb, memcached, mongo, mysql, openldap, opensearch, postgis, postgres, qdrant, rabbitmq, redis, typesense, valkey. Volumes the script already symlinked stay where they are; a database volume misplaced on the HDD has to be moved back by hand.

Storage Optimizer
Description
This role optimizes storage allocation for Docker volumes by migrating volumes between SSD (rapid storage) and HDD (mass storage) based on container image types. It creates symbolic links to maintain consistent storage paths after migration.
Overview
The role performs the following tasks:
- Migrates Docker volumes with database workloads to rapid storage (SSD) for improved performance.
- Moves non-database Docker volumes to mass storage (HDD) to optimize storage usage.
- Manages container stopping and restarting during the migration process.
- Creates symbolic links to preserve consistent file paths.
Cosmos
The diagram places Storage Optimizer in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.
Purpose
The primary purpose of this role is to enhance system performance by ensuring that Docker volumes are stored on the most appropriate storage medium, optimizing both speed and capacity.
Features
- Dynamic Volume Migration: Moves Docker volumes based on container image types.
- Symbolic Link Creation: Maintains consistent access paths after migration.
- Container Management: Safely stops and starts containers during volume migration.
- Performance Optimization: Improves overall system performance by leveraging appropriate storage media.
Quick Setup
Development
Clone, set up the workstation, and deploy Storage Optimizer onto the local stack:
git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=svc-opt-ssd-hdd full_cycle=false
Production
Install Storage Optimizer directly onto the target machine: clone the repository, install the OS prerequisites and the repository toolchain, then deploy against localhost over a local connection (no SSH, no container):
git clone https://github.com/infinito-nexus/core.git
cd core
bash scripts/install/package.sh
make install
source scripts/meta/env/load.sh
APP=svc-opt-ssd-hdd
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"
INVENTORY=inventories/production
infinito administration inventory provision "$INVENTORY" \
--inventory-file "$INVENTORY/devices.yml" \
--host localhost \
--include "$APP" \
--vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}"
infinito administration deploy dedicated "$INVENTORY/devices.yml" \
