Build The App

REGION=us-west-2
S3_BUCKET_NAME=$(aws sts get-caller-identity --query "Account" --output text)-${REGION}-$(cat /dev/urandom | tr -dc 'a-z0-9' | fold -w 16 | head -n 1)
aws s3 mb s3://${S3_BUCKET_NAME} --region $REGION
# TODO Update Bucket Policy for SAR Access
sam build
sam package -t .aws-sam/build/template.yaml --s3-bucket $S3_BUCKET_NAME --output-template-file packaged.yaml
sam publish -t packaged.yaml --region $REGION

Now we'll fetch the ARN of the SAR App

aws serverlessrepo list-applications --query "Applications[?Name == 'Cloud9BootStrapper'].ApplicationId" --region $REGION --output text
