Deployment Steps
Phase 1: Pre-Deployment Setup
Step 1.1: Environment Preparation
# Verify current system state
# TODO: Add commands to check current deployment version
# Backup current configuration
# TODO: Add backup commands
Verification:
- Current version identified
- Backups completed successfully
Step 1.2: Enable Maintenance Mode (if applicable)
# TODO: Add commands to enable maintenance mode
Verification:
- Maintenance page visible
- Traffic routing confirmed
Phase 2: Deployment Execution
Step 2.1: Database Migration (if applicable)
# Run database migrations
# TODO: Add migration commands
Verification:
- Migrations completed without errors
- Schema changes applied correctly
- Data integrity verified
Step 2.2: Application Deployment
# Deploy new application version
# TODO: Add deployment commands (e.g., kubectl apply, docker deploy, etc.)
Verification:
- New version deployed
- Pods/instances healthy
- No deployment errors
Step 2.3: Configuration Updates
# Update configuration/environment variables
# TODO: Add configuration update commands
Verification:
- Configuration changes applied
- Services reloaded/restarted
Step 2.4: Service Restart/Reload
# Restart affected services
# TODO: Add restart commands
Verification:
- All services running
- Health checks passing
Phase 3: Post-Deployment Verification
Step 3.1: Health Checks
# Verify service health
# TODO: Add health check commands
Verification:
- All health endpoints returning 200
- No error logs in past 5 minutes
- All instances/pods ready
Step 3.2: Functional Testing
- Test Case 1: [Description] - Expected: [result]
- Test Case 2: [Description] - Expected: [result]
- Test Case 3: [Description] - Expected: [result]
Step 3.3: Monitoring Verification
Key Metrics to Monitor:
- Response time: [threshold]
- Error rate: [threshold]
- Throughput: [threshold]
- Resource utilization: [threshold]
# Check key metrics
# TODO: Add commands to query metrics
Step 3.4: Disable Maintenance Mode
# TODO: Add commands to disable maintenance mode
Verification:
- Normal traffic restored
- Users can access application
Rollback Plan
Rollback Decision Criteria
Initiate rollback if any of the following occur:
- Error rate exceeds [threshold]% for more than [duration] minutes
- Critical functionality broken (specifically: [list critical features])
- Performance degradation > [threshold]% from baseline
- Database corruption or data loss detected
- [Other critical failure condition]
Rollback Procedure
Step R.1: Initiate Rollback
# Stop new deployment
# TODO: Add commands to halt deployment
Step R.2: Revert Application
# Deploy previous version
# TODO: Add rollback deployment commands
Verification:
- Previous version deployed
- Services healthy
Step R.3: Revert Database (if needed)
# Rollback database migrations
# TODO: Add migration rollback commands
Verification:
- Database schema reverted
- Data integrity verified
Step R.4: Revert Configuration
# Restore previous configuration
# TODO: Add configuration restore commands
Verification:
- Configuration restored
- Services using correct config
Step R.5: Verify Rollback
- System functionality restored
- Error rates normalized
- No data loss
- Users can access application
Post-Rollback Actions
- Notify stakeholders of rollback
- Document rollback reason
- Schedule post-mortem
- Update deployment status
Verification
Success Criteria
- All services healthy for [duration] minutes
- Error rate < [threshold]%
- Response time within [threshold]ms
- No critical errors in logs
- All functional tests passing
- User traffic processing normally
Post-Deployment Monitoring Focus
Monitor for:
- Application errors and exceptions
- Performance metrics (latency, throughput)
- Resource utilization
- User-reported issues
- Business metrics (if applicable)
