Infrastructure as Code

This directory contains Infrastructure as Code (IaC) configurations using Terraform, primarily for managing storage and backend services.

Services Overview

RustFS Storage

Loki Buckets: Dedicated storage for Grafana Loki log aggregation
Terraform Backend: Centralized state management for all Terraform configurations

RustFS speaks the S3 API but not MinIO's Admin API, so buckets are managed with the AWS provider while lifecycle rules and IAM users/policies use the official rc client. See rustfs/README.md.

External Resources

Kubernetes YAML: Managed in separate repository ryan4yin/k8s-gitops
Secrets Management: Handled via agenix in ../secrets

Usage

Each subdirectory contains its own Terraform configuration:

Navigate to specific service:
```
cd infra/rustfs/loki
```
Deploy configuration:
```
bash run.sh
```

Manual deployment:

terraform init
terraform plan
terraform apply

Security Considerations

Buckets are declared as bare aws_s3_bucket resources, with no bucket policy or server-side encryption configuration. The only guard in Terraform is prevent_destroy on the tf-s3-backend state bucket.
IAM users and policies are created by hand with the rc client, not Terraform (see rustfs/README.md).
Access credentials are managed through environment variables (AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY).
