AWS Console-to-Code を試してみた

aws ec2 run-instances --image-id "ami-0123456789xxxxxxx" --instance-type "t2.micro" --network-interfaces '{"AssociatePublicIpAddress":true,"DeviceIndex":0,"Groups":["sg-0ecf56e92f1e2a8da"]}' --credit-specification '{"CpuCredits":"standard"}' --tag-specifications '{"ResourceType":"instance","Tags":[{"Key":"Name","Value":"My Web Server"}]}' --metadata-options '{"HttpEndpoint":"enabled","HttpPutResponseHopLimit":2,"HttpTokens":"required"}' --private-dns-name-options '{"HostnameType":"ip-name","EnableResourceNameDnsARecord":true,"EnableResourceNameDnsAAAARecord":false}' --count "1"

# Reasoning: This code creates an EC2 instance with the specified configuration from the provided AWS CLI commands. It creates a security group that allows inbound HTTP traffic, and then creates an EC2 instance with the specified AMI, instance type, network interface, credit specification, tags, metadata options, and private DNS name options. The instance is configured to install and start the Apache HTTP server, and its public IP address is exported as a CloudFormation output. The code follows best practices for infrastructure as code by using the AWS CDK to define the resources in a declarative and reusable way.
