||||
|
||||
**Documentation Spec:**
|
||||
- Single-node appliance
|
||||
- Control plane orchestrates storage, backup, object storage, tape, and iSCSI
|
||||
- Unified API and UI
|
||||
|

|
||||
- ✅ React-based UI
|
||||
- ✅ Unified API endpoints for all subsystems
|
||||
|
||||
**Status:** ✅ **FULLY ALIGNED**
|
||||
|
||||
---
|
||||
|
||||

|
||||
|
||||
**Current Implementation:**

|
||||
- ✅ Ubuntu 24.04 LTS (as per install script)
|
||||
- ✅ Systemd service management
|
||||
- ✅ 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:**
|
||||
```
|
||||

||||
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

|
||||
|
||||
## 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
|
||||
|
||||
### 7.1 Request Flow ✅ **ALIGNED**
|
||||
|
||||
**Documentation Spec:**
|
||||
- User actions handled by Calypso API
|
||||
- Operations executed on ZFS datasets
|
||||
- Metadata stored centrally in ZFS
|
||||
|
||||
**Current Implementation:**
|
||||
- ✅ User actions via API
|
||||
- ✅ ZFS operations via storage service
|
||||
- ⚠️ Metadata stored in PostgreSQL (not ZFS)
|
||||
|
||||
**Note:** Current implementation uses PostgreSQL for metadata, which is acceptable but differs from spec. This is actually a better practice for metadata management.
|
||||
|
||||
**Status:** ✅ **FUNCTIONALLY ALIGNED** (with improvement)
|
||||
|
||||
---
|
||||
|
||||
## 8. Environment Configuration Review
|
||||
|
||||
### 8.1 Development Environment ✅ **ALIGNED**

||||
|
||||
**Current Implementation:**
|
||||
- ✅ Development setup in `/development/calypso/`
|
||||
- ✅ Separate dev and production configs
|
||||
- ✅ Development systemd service
|
||||
- ✅ Build scripts
|
||||
|
||||
**Status:** ✅ **ALIGNED**
|
||||
|
||||
---
|
||||
|
||||
### 8.2 Production Environment ⚠️ **NEEDS IMPROVEMENT**
|
||||
|
||||
**Gaps Identified:**
|
||||
1. No production deployment script
|
||||
2. No production directory structure setup
|
||||
3. No production configuration templates
|
||||
|
||||
**Recommendations:**
|
||||
- [ ] Create production deployment script
|
||||
- [ ] Set up production directory structure
|
||||
- [ ] Create production configuration templates
|
||||
|
||||
**Status:** ⚠️ **NEEDS IMPROVEMENT**

|
||||
|
||||
## 12. Conclusion
|
||||
|
||||
The current infrastructure and environment implementation is **functionally aligned** with the architecture specification in terms of core functionality and component integration. However, there are **structural gaps** in filesystem organization, binary deployment, and upgrade/rollback mechanisms.
|
||||
|
||||
**Key Strengths:**
|
||||
- ✅ Solid component architecture
|
||||
- ✅ Good security implementation
|
||||
- ✅ Proper technology stack
|
||||
- ✅ Functional data flow
|
||||
|
||||
**Key Gaps:**
|
||||
- ❌ Filesystem organization per spec
|
||||
- ❌ Versioned release structure
|
||||
- ❌ Upgrade/rollback mechanism
|
||||
|
||||
**Overall Assessment:** The system is **production-ready for functionality** but needs **structural improvements** for enterprise-grade deployment and maintenance.
