Future Homelab - OpenTofu, K3S, Ansible & DevOps
Documentation of the migration to a modern infrastructure based on Kubernetes and DevOps practices.
Vision
Evolve my homelab towards an infrastructure that is:
- Cloud-native with Kubernetes (K3S)
- Infrastructure as Code with OpenTofu
- Highly automated with Ansible and GitOps
- Observable with advanced monitoring and logging
Target Tech Stack
Orchestration
- K3S: Lightweight and performant Kubernetes distribution
- Helm: Package manager for Kubernetes
- ArgoCD: GitOps for continuous deployment
Infrastructure as Code
- OpenTofu: Open-source fork of Terraform for IaC
- Ansible: Configuration management and provisioning
- Git: Version control for all infrastructure
DevOps & CI/CD
- Forgejo Actions: Integrated CI/CD
- GitOps: Declarative and versioned deployment
- Kustomize: Kubernetes configuration management
Observability
- Prometheus: Metrics and alerting
- Grafana: Visualization and dashboards
- Loki: Log aggregation
- Tempo: Distributed tracing
Migration Goals
Technical
- Horizontal scalability
- High availability
- Automated deployments
- Complete observability
Learning
- Master Kubernetes in production
- Practice Infrastructure as Code
- Implement DevOps best practices
- Explore cloud-native technologies
Roadmap
The migration happens in stages:
- Phase 1: Basic K3S setup
- Phase 2: Migration of critical services
- Phase 3: GitOps implementation (ArgoCD)
- Phase 4: Observability and monitoring
- Phase 5: Complete automation with OpenTofu
Each step is documented with encountered challenges and solutions provided.
Why This Evolution?
This migration represents:
- Professional skills: Technologies used in enterprise
- Practical learning: Experimentation in real conditions
- Technical evolution: Moving to modern and scalable solutions
- Portfolio: Demonstration of advanced DevOps skills
