This commit adds complete documentation and tooling for migrating from
local development (Kind/Colima on macOS) to production deployment
(MicroK8s on Ubuntu VPS at Clouding.io).
Documentation added:
- K8S-MIGRATION-GUIDE.md: Comprehensive step-by-step migration guide
covering all phases from VPS setup to post-deployment operations
- MIGRATION-CHECKLIST.md: Quick reference checklist for migration tasks
- MIGRATION-SUMMARY.md: High-level overview and key changes summary
Configuration updates:
- Added storage-patch.yaml for MicroK8s storage class compatibility
(changes from 'standard' to 'microk8s-hostpath')
- Updated prod/kustomization.yaml to include storage patch
Helper scripts:
- deploy-production.sh: Interactive deployment script with validation
- tag-and-push-images.sh: Automated image tagging and registry push
- backup-databases.sh: Database backup script for production
Key differences addressed:
- Ingress: MicroK8s addon vs custom NGINX
- Storage: MicroK8s hostpath vs Kind standard storage
- Registry: Container registry configuration for production
- SSL: Let's Encrypt production certificates
- Domains: Real domain configuration vs localhost
- Resources: Production-grade resource limits and scaling
The migration guide covers:
- VPS setup and MicroK8s installation
- Configuration adaptations required
- Container registry setup options
- SSL certificate configuration
- Monitoring and backup setup
- Troubleshooting common issues
- Security hardening checklist
- Rollback procedures
All existing Kubernetes manifests remain unchanged and compatible.
