Provides AWS CloudFormation patterns for EC2 instances, Security Groups, IAM roles, and load balancers. Use when creating EC2 instances, SPOT instances, Security Groups, IAM roles for EC2, Application Load Balancers (ALB), Target Groups, and implementing template structure with Parameters, Outputs, Mappings, Conditions, and cross-stack references.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AWS CloudFormation EC2 Infrastructure
## Overview
Create production-ready EC2 infrastructure using AWS CloudFormation templates. Covers EC2 instances (On-Demand and SPOT), Security Groups, IAM roles, Application Load Balancers (ALB), template structure, parameters, outputs, and cross-stack references.
## When to Use
- Creating EC2 instances (On-Demand or SPOT) with Security Groups and IAM roles
- Setting up Application Load Balancers with target groups
- Implementing template Parameters, Mappings, Conditions, and cross-stack references
## Instructions
### Step 1 — Define Template Parameters
Use AWS-specific parameter types for validation and console dropdowns.
```yaml
Parameters:
LatestAmiId:
Type: AWS::SSM::Parameter::Value<AWS::EC2::Image::Id>
Default: /aws/service/ami-amazon-linux-latest/amzn2-ami-hvm-x86_64-gp2
InstanceType:
Type: AWS::EC2::InstanceType
Default: t3.micro
AllowedValues: [t3.micro, t3.small, t3.medium]
KeyName:
Type: AWS::EC2::KeyPair::KeyName
```
See [template-structure.md](references/template-structure.md) for advanced parameter patterns, mappings, conditions, and cross-stack references.

How to install
mdr add giuseppe-trisciuoglio/developer-kit/aws-cloudformation-ec2@sha256:f9dc198a7d41dc16The line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
