Mock Terraform Resource Generator
Generates example Terraform resource blocks for learning and testing
About this generator
Reading Terraform documentation is one thing; seeing a complete, working resource block you can study and adapt is faster for learning HCL structure. This tool generates one of four AWS resource blocks at random — an S3 bucket, an EC2 instance, a security group, or an RDS database instance — each with the correct HCL syntax: resource type and name, arguments, tags, and nested blocks where needed. There are no inputs — click Generate to get a different resource each time. The S3 bucket example includes a tags block with Environment and Team. The security group shows an ingress nested block with CIDR ranges. The RDS block includes a generated 12-character placeholder password to illustrate the field — never use a hard-coded password in a real .tf file. Copy the output into a .tf file to study the syntax or scaffold a starting point. Replace placeholder values with variables and real names before applying to any environment. Store secrets in a secrets manager and reference them via a Terraform data source rather than embedding them in source files.
How to use
- Click Generate to produce a resource block.
- Copy the HCL into a file or doc.
- Adapt the names and arguments.
- Keep real secrets out of the file.
Use Cases
- •Learning Terraform and HCL
- •Documenting infrastructure
- •Demoing resource structure
- •Seeding example config
- •Testing an HCL parser
Tips
- →Never commit real secrets to HCL.
- →Use variables and a secrets manager.
- →Adapt resource names to your infra.
- →Use it to learn HCL structure.
FAQ
what resource types can the generator produce
It picks one of four at random: aws_s3_bucket, aws_instance (EC2 t3.micro), aws_security_group (with an HTTPS ingress block), and aws_db_instance (Postgres, db.t3.micro). There is no way to request a specific type — keep clicking Generate to see all four.
what is a terraform resource block
A resource block declares a piece of infrastructure Terraform will create and manage. It starts with the keyword resource, then the provider resource type (e.g. aws_s3_bucket), then a local name you reference elsewhere in the config. The body contains arguments specific to that resource type.
is it safe to put a password directly in a terraform file
No. The generated db_instance block includes a placeholder password to show the field exists, but you should never commit a real secret to a .tf file. Use a Terraform variable marked sensitive and supply the value from an environment variable or a secrets manager, and ensure your state file is stored securely — it can contain secret values in plaintext.
what is the difference between a resource and a data source in terraform
A resource block creates and manages infrastructure that Terraform owns; destroying the resource destroys the real thing. A data source only reads existing infrastructure or values to reference elsewhere and never creates or destroys anything. The generator produces resource blocks; data sources use a 'data' block instead.
