|
||||
|
||||
## Overview
|
||||
Define the environment strategy for the project, including configuration, access, and deployment procedures for each environment.
|
||||
|
||||
---
|
||||
|
||||
## Environments
|
||||
|
||||
### Development (dev)

||||
**Purpose**: Local development and feature testing
|
||||
|
||||
| Aspect | Configuration |
|
||||
|--------|---------------|
|
||||
| Branch | `dev`, feature branches |
|
||||
| Database | Local or shared dev instance |

|
||||
| Logging Level | DEBUG |
|
||||
| Access | All developers |
|
||||
|
||||
**Configuration**:
|
||||
```

## Secrets Management
|
||||
|
||||
### Secret Categories
|
||||
- Database credentials
|
||||
- API keys (internal and external)
|
||||
- Encryption keys
|
||||
- Service account credentials
|
||||
|
||||
### Storage

|
||||
|
||||
## Environment Parity
|
||||
|
||||
### Required Parity
|
||||
- Same database engine and version
|
||||
- Same runtime version
|
||||
- Same dependency versions
|
||||
- Same configuration structure
|
||||
|
||||
### Allowed Differences
|
||||
- Resource scaling (CPU, memory)
|
||||
- External service endpoints (sandbox vs production)
|
||||
- Logging verbosity
|
||||
- Feature flags
|
||||

||||
| Role | Dev | Staging | Production |
|
||||
|------|-----|---------|------------|
|
||||
| Developer | Full | Read + Deploy | Read logs only |

||||
| DevOps | Full | Full | Full |
|
||||
| Stakeholder | None | Read | Read dashboards |

## Backup & Recovery
|
||||
|
||||
| Environment | Backup Frequency | Retention | RTO | RPO |
|
||||
|-------------|------------------|-----------|-----|-----|
|
||||
| Development | None | N/A | N/A | N/A |
|
||||
| Staging | Daily | 7 days | 4 hours | 24 hours |
|
||||
| Production | Hourly | 30 days | 1 hour | 1 hour |
|
||||
|
||||
---
|
||||
|
||||
## Notes
|
||||
- Never copy production data to lower environments without anonymization
|
||||
- All environment-specific values must be externalized (no hardcoding)
|
||||
- Document any environment-specific behaviors in code comments

# Feature Dependency Matrix
|
||||
|
||||
Track feature dependencies to ensure proper implementation order.
|
||||
|
||||
---
|
||||
|
||||
## Active Features
|
||||
|
||||
| Feature ID | Feature Name | Status | Dependencies | Blocks |
|
||||
|------------|--------------|--------|--------------|--------|
|
||||
| | | Draft/In Progress/Done | List IDs | List IDs |
|
||||
|
||||
---
|
||||
|
||||
## Dependency Rules
|
||||
|
||||
### Status Definitions
|
||||
- **Draft**: Spec created, not started
|
||||
- **In Progress**: Development started
|
||||
- **Done**: Merged to dev, verified
|
||||
- **Blocked**: Waiting on dependencies
|
||||
|
||||
### Dependency Types
|
||||
- **Hard**: Cannot start without dependency complete
|
||||
- **Soft**: Can mock dependency, integrate later
|
||||
- **API**: Depends on API contract (can parallelize with mock)
|
||||
- **Data**: Depends on data/schema (must be complete)
|
||||
|
||||

|
||||
|
||||
## Current Dependencies
|
||||
|
||||
### [Feature A] depends on:
|
||||
| Dependency | Type | Status | Blocker? |
|
||||
|------------|------|--------|----------|
|
||||
| | Hard/Soft/API/Data | Done/In Progress | Yes/No |
|
||||
|
||||
### [Feature B] depends on:
|
||||
| Dependency | Type | Status | Blocker? |
|
||||
|------------|------|--------|----------|

## Dependency Graph
|
||||
|
||||
```
|
||||
Feature A (Done)
|
||||
└── Feature B (In Progress)
|
||||
└── Feature D (Draft)
|
||||
└── Feature C (Draft)
|
||||
|
||||
Feature E (Done)
|
||||
└── Feature F (In Progress)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Implementation Order
|
||||
|
||||
Based on dependencies, recommended implementation order:
|
||||
|
||||
1. **Phase 1** (No dependencies)
|
||||
- [ ] Feature X
|
||||
- [ ] Feature Y
|
||||
|
||||
2. **Phase 2** (Depends on Phase 1)
|
||||
- [ ] Feature Z (after X)
|
||||
- [ ] Feature W (after Y)
|
||||
|
||||
3. **Phase 3** (Depends on Phase 2)
|
||||
- [ ] Feature V (after Z, W)
|
||||
|
||||
---
|
||||
|
||||
## Handling Blocked Features
|
||||
|
||||
When a feature is blocked:
|
||||
|
||||
1. **Identify** the blocking dependency
|
||||
2. **Escalate** if blocker is delayed
|
||||
3. **Consider** if feature can proceed with mocks
|
||||
4. **Document** any workarounds used
|
||||
5. **Schedule** integration when blocker completes
|
||||

## Automated Gate Checks
|
||||
|
||||
### CI Pipeline Gates
|
||||
```yaml
|
||||
gates:
|
||||
build:
|
||||
- compilation_success: true
|
||||
|
||||
quality:
|
||||
- lint_errors: 0
|
||||
- code_coverage: ">= 75%"
|
||||
- code_smells: "< 10 new"
|
||||
|
||||
security:
|
||||
- critical_vulnerabilities: 0
|
||||
- high_vulnerabilities: 0
|
||||
|
||||
tests:
|
||||
- unit_tests_pass: true
|
||||
- integration_tests_pass: true
|
||||
```
|
||||
|
||||
### Manual Gate Checks
|
||||
Some gates require human verification:
|
||||
- Architecture review
|
||||
- Security review
|
||||
- UX review (for UI changes)
|
||||
- Stakeholder sign-off
|
||||
|
||||
---
|
||||
|
||||
## Gate Failure Handling
|
||||
|
||||
When a gate fails:
|
||||
1. **Stop** - Do not proceed to next phase
|
||||
2. **Identify** - Determine which checks failed
|
||||
3. **Fix** - Address the failures
|
||||
4. **Re-verify** - Run gate checks again
|
||||
5. **Document** - If exception needed, get approval and document reason
|
||||
|
||||
---
|
||||
|
||||
## Exception Process
|
||||
|
||||
If a gate must be bypassed:
|
||||
1. Document the reason
|
||||
2. Get tech lead approval
|
||||
3. Create follow-up task to address
|
||||
4. Set deadline for resolution
|
||||
5. Add to risk register

||||
- [ ] Incident acknowledged and documented
|
||||
- [ ] Stakeholders notified of rollback decision
|
||||
- [ ] Current state captured (logs, metrics snapshot)

|
||||
|
||||
## Rollback Procedures
|
||||
|
||||
### Application Rollback
|
||||
|
||||
#### Option 1: Revert Deployment (Preferred)
|
||||
```bash
|
||||
# Using CI/CD
|
||||
# Trigger previous successful deployment
|
||||
|
||||
# Manual (if needed)
|
||||
git revert <commit-hash>
|
||||
git push origin main
|
||||
```
|
||||
|
||||
#### Option 2: Blue-Green Switch
|
||||
```bash
|
||||
# Switch traffic to previous version
|
||||
# [Platform-specific commands]
|
||||
```
|
||||
|
||||
#### Option 3: Feature Flag Disable
|
||||
```bash
|
||||
# Disable feature flag
|
||||
# [Feature flag system commands]
|
||||
```
|
||||
|
||||
### Database Rollback
|
||||
|
||||
#### If Migration is Reversible
|
||||
```bash
|
||||
# Run down migration
|
||||
# [Migration tool command]
|
||||
```
|
||||
|
||||
#### If Migration is NOT Reversible
|
||||
1. [ ] Restore from backup
|
||||
2. [ ] Point-in-time recovery to pre-deployment
|
||||
3. [ ] **WARNING**: May cause data loss - requires approval
|
||||
|
||||
### Configuration Rollback
|
||||
```bash
|
||||
# Restore previous configuration
|
||||
# [Config management commands]
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Post-Rollback Verification
|
||||
|
||||
### Immediate (0-5 minutes)
|
||||
- [ ] Service responding to health checks
|
||||
- [ ] No error spikes in logs
|
||||
- [ ] Basic functionality verified
|
||||
|
||||
### Short-term (5-30 minutes)
|
||||
- [ ] All critical paths functional
|
||||
- [ ] Error rate returned to baseline
|
||||
- [ ] Performance metrics normal
|
||||
|
||||
### Extended (30-60 minutes)
