AI Wrote My Terraform Code for AWS S3 โ€” And It Actually Works! ๐Ÿค–โœจ

This isn't a demo. It's working Terraform

Written 90% by AI. Deployed 100% on AWS

๐Ÿ“Œ 1-Minute Recap

What happens when you let AI write Terraform for real cloud infrastructure?

  • โœ… GPT/Mistral generated a working AWS S3 module

  • โœ… Terraform init, plan, apply all succeeded

  • โœ… S3 bucket deployed with versioning

  • โš ๏ธ Missing: encryption, IAM, lifecycle rules, logging

๐Ÿ“ฅ Full source code + prompt inside.

๐Ÿ‘€ Who This Is For

  • You deploy infrastructure using Terraform, AWS, or Azure

  • Youโ€™re exploring how AI can accelerate DevOps

  • Youโ€™re curious what works โ€” and what breaks โ€” when AI writes your IaC

๐Ÿ› ๏ธ The Setup: GPT Writes Terraform

I asked GPT/Mistral to generate:

"A clean Terraform module to create an AWS S3 bucket with versioning, variables, and outputs."

It generated this:

๐Ÿ“ ai-terraform-s3-demo/

โ”œโ”€โ”€ main.tf # S3 resource with versioning

โ”œโ”€โ”€ variables.tf # Type-safe variables

โ”œโ”€โ”€ outputs.tf # Bucket name output

I ran:

terraform init terraform plan terraform apply

And it worked perfectly.

๐Ÿ” Whatโ€™s Missing for Production

AI got 80% right โ€” but hereโ€™s what youโ€™ll still need to add:

  • โŒ Encryption โ€“ no SSE config

  • โŒ IAM permissions โ€“ no access policies

  • โŒ Lifecycle rules โ€“ for cleanup or archival

  • โŒ Logging โ€“ no access logging to another bucket

๐Ÿ” Bottom line: AI is great for scaffolding, but you still own security and compliance.

๐Ÿ”„ My Prompting Tips

Want to replicate this?

๐Ÿ’ก Prompt structure I used:

โ€œWrite a Terraform module that creates an AWS S3 bucket with versioning. Include main.tf, variables.tf, and outputs.tf. Use clean naming.โ€

๐Ÿง  Pro Tip: Be specific with resource, features, and structure โ€” GPT handles infra better with clear constraints.

๐ŸŽฏ Why This Matters

This isn't just a cool AI trick. Itโ€™s a workflow shift.

  • Saves 30โ€“60 minutes of manual Terraform writing

  • Great for prototyping infrastructure modules

  • Makes onboarding junior engineers faster

And now you have a story to share:

โ€œTell me about a time you used AI in a DevOps projectโ€ฆโ€

Now youโ€™ve got an answer.
