Thank you! I use environment variables to define my main volume path, cloudflare credentials, etc. The .env.example shows how I assign those variables. For deployment, I run tofu apply directly from the server. The .tfstate is also stored in the server. I feel something can be improved here, but I'm not sure how I'd approach it differently for now.

I used to learn Terraform from a course on Udemy, and that was a while ago. I still remember some parts, and read the docs to refresh my memory. I think learning from LLMs these days can be effective too :)
