External resources

WIP documents

These resources are optional, the homelab still works without them but will lack some features like trusted certificates and offsite backup

Although I try to keep the amount of external resources to the minimum, there's still need for a few of them. Below is a list of external resources and why we need them (also see some alternatives below).

• Terraform Cloud:
  • Workspace to store the state for external resources
• Cloudflare:
  • DNS
  • DNS-01 challenge for Let's Encrypt
  • Tunnel to public services to the internet without port-forwarding
• Backblaze:
  • B2 storage with S3 compatible API for offsite backup

This layer will:

• Create external resources
• Add external secrets to namespaces
