AWS CloudFormation 建立失敗：The key pair 'irkp' does not exist (Service: AmazonEC2; Status Code: 400; Error Code: InvalidKeyPair.NotFound

Problem

當我透過 CLI 建立相關 AWS 資源

aws cloudformation create-stack --stack-name CodeDeployDemoStack-2 \
--template-url https://my-cf-template-347854199521.s3.amazonaws.com/CF_Template.json \
--parameters ParameterKey=InstanceCount,ParameterValue=1 \
ParameterKey=InstanceType,ParameterValue=t3.micro \
ParameterKey=KeyPairName,ParameterValue=irkp \
ParameterKey=OperatingSystem,ParameterValue=Linux \
ParameterKey=SSHLocation,ParameterValue=0.0.0.0/0 \
ParameterKey=TagKey,ParameterValue=Name \
ParameterKey=TagValue,ParameterValue=CodeDeployDemo \
--capabilities CAPABILITY_IAM

出現以下錯誤

Root Cause

因為指令列中的 key pair 不存在

How-To

修正 AWS CLI 為存在的的 key pair 名字

aws cloudformation create-stack --stack-name CodeDeployDemoStack-3 \
--template-url https://my-cf-template-347854199521.s3.amazonaws.com/CF_Template.json \
--parameters ParameterKey=InstanceCount,ParameterValue=1 \
ParameterKey=InstanceType,ParameterValue=t3.micro \
ParameterKey=KeyPairName,ParameterValue=nvkp \
ParameterKey=OperatingSystem,ParameterValue=Linux \
ParameterKey=SSHLocation,ParameterValue=0.0.0.0/0 \
ParameterKey=TagKey,ParameterValue=Name \
ParameterKey=TagValue,ParameterValue=CodeDeployDemo \
--capabilities CAPABILITY_IAM

執行結果
