Hi there! This is my homelab where I try out new technologies, run home services, & play games with.

Terraform Organization

Feel free to checkout any of the following directories for more information about the terraform workspaces & modules that bring it all together.

Each terraform workspace / module has documentation generated by terraform-docs that shows a rough idea of what is going on.

Terraform workspaces are located in infra/

Terraform modules are either in:

• The top-level modules/ directory

  if the module can be used across different terraform workspaces

• As subfolders within an existing terraform workspace in infra/

  if the module is non-portable and only meant to organize code within a single workspace

Terraform workspaces / modules:

• infra/proxmox/terraform
• infra/proxmox/terraform/modules/proxmox_cloudinit_vm
• infra/proxmox/terraform/modules/proxmox_cloudinit_vm/modules/unifi_host_dns_records
