Use this skill

Your agent runs on

Adds every file the skill has, pinned so you can update it. No account needed.

pip install "decimalai>=0.15"
decimalai skills add giuseppe-trisciuoglio-aws-cloudformation-ec2
claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

The same install from Python, for a notebook or a setup script.

Install

pip install "decimalai>=0.15"

Add the skill

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("giuseppe-trisciuoglio-aws-cloudformation-ec2")
if result.exit_code:
    raise SystemExit(result.problems)

print("Added. Start Claude Code with the command below.")

Start Claude Code with it

claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

Type these in a Claude Code session. No account or API key. It writes the skill and any files it bundles, and asks first when its safety rating isn't Passed.

Add the DecimalAI plugin, once

/plugin marketplace add decimal-labs/decimalai-claude-plugins
/plugin install decimalai@decimalai

Install this skill

/decimalai:install giuseppe-trisciuoglio-aws-cloudformation-ec2

The plugin needs python3 and curl on your machine.

No Python or account. Claude Code picks it up in its next session.

Save it into your project

curl -fsSL --create-dirs -o .claude/skills/giuseppe-trisciuoglio-aws-cloudformation-ec2/SKILL.md https://app.decimal.ai/s/giuseppe-trisciuoglio-aws-cloudformation-ec2/SKILL.md

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.

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 for advanced parameter patterns, mappings, conditions, and cross-stack references.

Step 2 — Create Security Group

Define ingress/egress rules for network access.

InstanceSecurityGroup:
  Type: AWS::EC2::SecurityGroup
  Properties:
    GroupDescription: Security group for EC2 instance
    VpcId: !Ref VpcId
    SecurityGroupIngress:
      - IpProtocol: tcp
        FromPort: 80
        ToPort: 80
        CidrIp: 0.0.0.0/0
      - IpProtocol: tcp
        FromPort: 22
        ToPort: 22
        CidrIp: 10.0.0.0/16

See security-iam.md for advanced security group patterns, self-references, and IAM roles.

Step 3 — Configure IAM Role

Define instance profile with least privilege permissions.

Ec2Role:
  Type: AWS::IAM::Role
  Properties:
    AssumeRolePolicyDocument:
      Version: "2012-10-17"
      Statement:
        - Effect: Allow
          Principal:
            Service: ec2.amazonaws.com
          Action: sts:AssumeRole
    ManagedPolicyArns:
      - arn:aws:iam::aws:policy/AmazonSSMManagedInstanceCore

Ec2InstanceProfile:
  Type: AWS::IAM::InstanceProfile
  Properties:
    Roles: [!Ref Ec2Role]

See security-iam.md for least privilege policies, SSM roles, and trust policies.

Step 4 — Launch EC2 Instance

Configure instance with security group, IAM role, and user data.

Ec2Instance:
  Type: AWS::EC2::Instance
  Properties:
    ImageId: !Ref LatestAmiId
    InstanceType: !Ref InstanceType
    KeyName: !Ref KeyName
    SecurityGroupIds: [!Ref InstanceSecurityGroup]
    IamInstanceProfile: !Ref Ec2InstanceProfile
    SubnetId: !Ref SubnetId
    UserData:
      Fn::Base64: |
        #!/bin/bash
        yum update -y
        yum install -y httpd
        systemctl start httpd
    Tags:
      - Key: Name
        Value: !Sub ${AWS::StackName}-instance

See ec2-instances.md for multi-volume configurations, detailed monitoring, SPOT instances, and complete stack examples.

Validate template: aws cloudformation validate-template --template-body file://template.yaml

Step 5 — Add Application Load Balancer

Create ALB with target group and listener for traffic distribution.

ApplicationLoadBalancer:
  Type: AWS::ElasticLoadBalancingV2::LoadBalancer
  Properties:
    Name: !Sub ${AWS::StackName}-alb
    Scheme: internet-facing
    SecurityGroups: [!Ref AlbSecurityGroup]
    Subnets: [!Ref PublicSubnet1, !Ref PublicSubnet2]

ApplicationTargetGroup:
  Type: AWS::ElasticLoadBalancingV2::TargetGroup
  Properties:
    Port: 80
    Protocol: HTTP
    VpcId: !Ref VpcId
    HealthCheckPath: /health

ApplicationListener:
  Type: AWS::ElasticLoadBalancingV2::Listener
  Properties:
    DefaultActions:
      - Type: forward
        TargetGroupArn: !Ref ApplicationTargetGroup
    LoadBalancerArn: !Ref ApplicationLoadBalancer
    Port: 80
    Protocol: HTTP

See load-balancers.md for HTTPS configuration, path-based routing, host-based routing, listener rules, and ALB attributes.

Step 6 — Define Outputs

Export values for cross-stack references.

Outputs:
  InstanceId:
    Description: EC2 Instance ID
    Value: !Ref Ec2Instance
    Export:
      Name: !Sub ${AWS::StackName}-InstanceId

  SecurityGroupId:
    Description: Security Group ID
    Value: !Ref InstanceSecurityGroup
    Export:
      Name: !Sub ${AWS::StackName}-SecurityGroupId

  LoadBalancerDnsName:
    Description: ALB DNS Name
    Value: !GetAtt ApplicationLoadBalancer.DNSName

See template-structure.md for cross-stack reference patterns and import/export strategies.

Examples

Minimal EC2 with ALB Template

AWSTemplateFormatVersion: "2010-09-09"
Description: EC2 instance with ALB

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

Resources:
  InstanceSecurityGroup:
    Type: AWS::EC2::SecurityGroup
    Properties:
      GroupDescription: Enable HTTP and SSH
      SecurityGroupIngress:
        - IpProtocol: tcp
          FromPort: 80
          ToPort: 80
          CidrIp: 0.0.0.0/0

  Ec2Instance:
    Type: AWS::EC2::Instance
    Properties:
      ImageId: !Ref LatestAmiId
      InstanceType: !Ref InstanceType
      SecurityGroupIds: [!Ref InstanceSecurityGroup]

  LoadBalancer:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Scheme: internet-facing
      SecurityGroups: [!Ref InstanceSecurityGroup]
      Subnets: [subnet-12345678, subnet-87654321]

Outputs:
  InstanceId:
    Value: !Ref Ec2Instance
  LoadBalancerDns:
    Value: !GetAtt LoadBalancer.DNSName

Deploy with Change Set

# Create change set
aws cloudformation create-change-set \
  --stack-name my-ec2-stack \
  --template-body file://template.yaml \
  --change-set-type CREATE

# Execute after review
aws cloudformation execute-change-set \
  --change-set-name <change-set-name>

See examples.md for complete production-ready templates.

Best Practices

Template Structure

Use AWS-specific parameter types for validation (AWS::EC2::VPC::Id, AWS::EC2::InstanceType)
Organize by lifecycle - separate network, security, and application stacks
Use meaningful names with AWS::StackName prefix
Enable termination protection on production stacks

Security

Apply least privilege to IAM roles - grant minimum required permissions
Use security group references instead of IP addresses where possible
Enable IMDSv2 on all EC2 instances
Restrict security group rules to specific CIDR blocks

Cost & Availability

Use SPOT instances for fault-tolerant, interruptible workloads
Deploy across multiple AZs for high availability
Set up CloudWatch alarms for CPU and status checks
Use EBS gp3 volumes for cost-effective storage

Operations

Always use change sets for production stack updates
Enable drift detection to maintain template compliance
Apply stack policies to protect critical resources
Validate templates before deployment with aws cloudformation validate-template

See best-practices.md for detailed guidance on stack policies, termination protection, drift detection, change set automation, and validation scripts.

EBS volumes charged per GB-month even when not attached
ALBs have hourly + LCU data processing costs
Unattached Elastic IPs incur hourly costs

Security Considerations

Key pairs cannot be recovered if lost
Instance profile roles cannot be changed after creation
IMDSv1 has security vulnerabilities - use IMDSv2
Spot instances can be terminated with 2-minute notice

See constraints.md for complete constraints, troubleshooting guides, and monitoring setup.

When it activates

Automatically, when a task matches. 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.
