Configure your CloudFormation managed infrastructure with Parameter Store and CodePipeline

Code for my blog post: Configure your CloudFormation managed infrastructure with Parameter Store and CodePipeline

Setup instructions

Have you installed and configured the AWS CLI?

1. Clone this repository git clone https://github.com/widdix/parameter-store-cloudformation-codepipeline.git download the ZIP file](https://github.com/widdix/parameter-store-cloudformation-codepipeline/archive/master.zip)
2. cd parameter-store-cloudformation-codepipeline/
3. Create parameter in Parameter Store: aws ssm put-parameter --name '/application/stage/instancetype' --value 't2.micro' --type String
4. Create pipeline stack with CloudFormation: aws cloudformation create-stack --stack-name cloudonaut --template-body file://pipeline.yaml --capabilities CAPABILITY_IAM
5. Wait until CloudFormation stack is created: aws cloudformation wait stack-create-complete --stack-name cloudonaut
6. Push files to the CodeCommit repository created by the pipeline stack (I don't use git push here to skip the git configuration):
   1. COMMIT_ID="$(aws codecommit put-file --repository-name cloudonaut --branch-name master --file-content file://infrastructure.yaml --file-path infrastructure.yaml --query commitId --output text)"
   2. COMMIT_ID="$(aws codecommit put-file --repository-name cloudonaut --branch-name master --parent-commit-id $COMMIT_ID --file-content file://infrastructure.json --file-path infrastructure.json --query commitId --output text)"
   3. COMMIT_ID="$(aws codecommit put-file --repository-name cloudonaut --branch-name master --parent-commit-id $COMMIT_ID --file-content file://vpc-2azs.yaml --file-path vpc-2azs.yaml --query commitId --output text)"
7. Wait until the first pipeline run is finished: open 'https://console.aws.amazon.com/codepipeline/home#/view/cloudonaut'
8. Visit the website exposed by the EC2 instance: open "http://$(aws cloudformation describe-stacks --stack-name cloudonaut-infrastructure --query "Stacks[0].Outputs[0].OutputValue" --output text)"
9. Update the parameter value: aws ssm put-parameter --name '/application/stage/instancetype' --value 't2.nano' --type String --overwrite (t2.nano is outside th Free Tier, expect charges of a few cents)
10. Wait until the second pipeline run is finished: open 'https://console.aws.amazon.com/codepipeline/home#/view/cloudonaut'
11. Visit the website exposed by the EC2 instance: open "http://$(aws cloudformation describe-stacks --stack-name cloudonaut-infrastructure --query "Stacks[0].Outputs[0].OutputValue" --output text)"

Clean up instructions

1. Remove CloudFormation stacks
   1. aws cloudformation delete-stack --stack-name cloudonaut-infrastructure
   2. aws cloudformation wait stack-delete-complete --stack-name cloudonaut-infrastructure
   3. aws cloudformation delete-stack --stack-name cloudonaut-vpc
   4. aws cloudformation wait stack-delete-complete --stack-name cloudonaut-vpc
   5. aws cloudformation delete-stack --stack-name cloudonaut
   6. aws cloudformation wait stack-delete-complete --stack-name cloudonaut
2. Remove S3 bucket prefixed with cloudonaut-artifactsbucket- including all files: open "https://s3.console.aws.amazon.com/s3/home"
3. Remove Parameter Store parameter: aws ssm delete-parameter --name '/application/stage/instancetype'
