Generate Terraform Infrastructure from Plain-English Requirements
Terraform is powerful but verbose — even simple infrastructure requires a lot of boilerplate. Describe what you need and Claude will write idiomatic HCL with sensible defaults.
Write Terraform for an AWS setup with:
- A VPC with two public and two private subnets across two availability zones
- An RDS PostgreSQL 16 instance in the private subnets (db.t3.medium)
- An EC2 Auto Scaling group behind an Application Load Balancer
- Security groups that allow HTTPS in, and the app to reach the database
- All credentials in variables with no hardcoded values
Claude will produce properly structured Terraform with a variables.tf, outputs.tf, and logical resource grouping. Specify your provider and region and it'll include the correct provider block too.
You can ask it to go further:
Add an S3 bucket for file storage with versioning enabled, a CloudFront
distribution in front of it, and an IAM role the app can assume to write to it.
Claude also helps when you're stuck on the Terraform way of doing something familiar:
I want to run a database migration command after my EC2 instance launches.
What's the correct Terraform pattern for this — user data, null_resource, or
something else?
Terraform is mostly typing. Let Claude do the typing.
Log in to leave a comment.
Set up Claude Code as an automated reviewer in your CI pipeline — on every pull request, it reads the diff, checks for bugs, security issues, missing tests, and convention violations, then posts its findings as a PR comment. Your human reviewers get a head start because the obvious issues are already flagged before they look.
Before deploying, tell Claude to read your project — migrations, environment variables, queue workers, scheduled tasks, caching, third-party integrations — and generate a deployment checklist that's specific to your app. Not a generic "did you run migrations?" list, but one that knows YOUR infrastructure and catches the things YOUR deploy can break.
Instead of writing a README from memory or copying a template, tell Claude to read your project and generate one that's actually accurate — real setup instructions from your config, real architecture from your directory structure, real API examples from your routes, and real prerequisites from your dependency files.
