# 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
|
|
