  • React-based UI
  • Unified API endpoints for all subsystems

Status: FULLY ALIGNED


1.2 Deployment Model ALIGNED

Documentation Spec:

  • Single-node deployment
  • Bare metal or VM (bare metal recommended)
  • Linux-based OS (LTS)

Current Implementation:

  • Single-node deployment
  • Ubuntu 24.04 LTS (as per install script)

  • Supports both bare metal and VM

Status: FULLY ALIGNED


2. Filesystem Architecture Review

2.1 Domain Separation ⚠️ PARTIALLY ALIGNED

Documentation Spec:

Domain          | Location
----------------|------------------
Binaries        | /opt/adastra/calypso
Configuration   | /etc/calypso
Data (ZFS)      | /srv/calypso
Logs            | /var/log/calypso
Runtime         | /var/lib/calypso, /run/calypso

Current Implementation:

  • ⚠️ Binaries: Currently in /development/calypso/backend/bin/ (development) or systemd service path
  • ⚠️ Configuration: Uses /etc/calypso/config.yaml (as per main.go flag default)
  • ⚠️ Data: Not explicitly organized under /srv/calypso/ structure
  • ⚠️ Logs: Not explicitly organized under /var/log/calypso/
  • ⚠️ Runtime: Not explicitly organized under /var/lib/calypso/ or /run/calypso/

Gaps Identified:

  1. Binary deployment structure not following /opt/adastra/calypso/releases/ pattern
  2. Data directory structure not organized per spec
  3. Log directory structure not organized per spec
  4. Runtime directory structure not organized per spec

Recommendations:

  • Create deployment script to organize binaries per spec
  • Create data directory structure under /srv/calypso/
  • Configure logging to use /var/log/calypso/
  • Configure runtime directories

Status: ⚠️ PARTIALLY ALIGNED - Structure exists but not fully organized per spec


2.2 Binary Layout ⚠️ NOT ALIGNED

Documentation Spec:

/opt/adastra/calypso/
  releases/
    1.0.0/
      bin/
      web/
      migrations/
      scripts/
  current -> releases/1.0.0
  third_party/

Current Implementation:

  • Binaries in backend/bin/calypso-api (development)
  • No versioned release structure
  • No symlink to current version
  • Frontend built to frontend/dist/ (not organized per spec)

Gaps Identified:

  1. No versioned release structure
  2. No symlink mechanism for atomic upgrades
  3. Frontend assets not organized per spec

Recommendations:

  • Create release packaging script
  • Implement versioned release structure
  • Create symlink mechanism for atomic upgrades
  • Organize frontend assets per spec

Status: NOT ALIGNED - Needs implementation


2.3 Configuration Layout ALIGNED

Documentation Spec:

/etc/calypso/
  calypso.yaml
  secrets.env
  tls/
  integrations/
  system/

Current Implementation:

  • Configuration file path: /etc/calypso/config.yaml (as per main.go)
  • config.yaml.example exists in repository
  • ⚠️ Other directories (secrets.env, tls/, integrations/, system/) not explicitly created

Status: MOSTLY ALIGNED - Main config path correct, subdirectories can be added


2.4 ZFS Data Layout ⚠️ NOT IMPLEMENTED

Documentation Spec:

/srv/calypso/
  db/
  backups/
  object/
  shares/
  vtl/
  iscsi/
  uploads/
  cache/
  _system/

Current Implementation:

  • No explicit /srv/calypso/ directory structure
  • ⚠️ ZFS datasets may be created but not organized per this structure
  • ⚠️ Data stored in various locations (database in PostgreSQL default, etc.)

Gaps Identified:

  1. No centralized data directory structure
  2. ZFS datasets not organized per spec
  3. Data scattered across system

Recommendations:

  • Create /srv/calypso/ directory structure
  • Organize ZFS datasets per spec
  • Update services to use centralized data locations

Status: NOT IMPLEMENTED - Needs implementation


3. Component Architecture Review

3.1 Core Components ALIGNED

Documentation Spec:

  • Calypso Control Plane (Go-based API)
  • ZFS (core storage)
  • Bacula (backup)
  • MinIO (object storage) ⚠️
  • SCST (iSCSI)
  • MHVTL (virtual tape library)

Current Implementation:

  • Go-based API implemented
  • ZFS integration implemented
  • Bacula/Bareos integration implemented
  • ⚠️ Object storage: UI exists but backend integration not confirmed
  • SCST integration implemented
  • MHVTL integration implemented

Status: MOSTLY ALIGNED - Object storage backend needs verification


4. Technology Stack Review

Documentation Spec:

  • Go-based API
  • PostgreSQL database
  • Systemd service management

Current Implementation:

  • Go 1.21+ (go.mod confirms)
  • PostgreSQL (database package confirms)
  • Systemd services (deploy/systemd/ confirms)
  • Gin web framework
  • Structured logging (zerolog)

Status: FULLY ALIGNED

6. Upgrade & Rollback Review

6.1 Version Management NOT IMPLEMENTED

Documentation Spec:

  • Versioned releases
  • Atomic switch via symlink
  • Data preserved independently in ZFS

Current Implementation:

  • No versioned release structure
  • No symlink mechanism
  • ⚠️ Data preservation depends on database backups

Gaps Identified:

  1. No release versioning system
  2. No atomic upgrade mechanism
  3. No rollback capability

Recommendations:

  • Implement release versioning
  • Create symlink-based upgrade mechanism
  • Document rollback procedures

Status: NOT IMPLEMENTED - Needs implementation


7. Data Flow Review
