##Create the Lambda function using SAM
cd ~/environment/theme-park-backend/3-photos/2-compositing
sam build
sam package --output-template-file packaged.yaml --s3-bucket $s3_deploy_bucket
sam deploy --template-file packaged.yaml --stack-name theme-park-photos --capabilities CAPABILITY_IAM --parameter-overrides "FinalBucketName"=$FINAL_BUCKET

##Adding the S3 trigger

aws lambda add-permission --function-name $COMPOSITE_FUNCTION --action lambda:InvokeFunction --statement-id s3-to-lambda-composite --principal s3.amazonaws.com --source-arn "arn:aws:s3:::$PROCESSING_BUCKET" --source-account $accountId

COMPOSITE_FUNCTION_ARN=$(aws lambda get-function --function-name $COMPOSITE_FUNCTION | grep FunctionArn | cut -d'"' -f 4)

aws s3api put-bucket-notification-configuration --bucket $PROCESSING_BUCKET --notification-configuration "$PROCESSING_NOTIFICATION_CONFIGURATION"

## Test Upload
cd ~/environment/theme-park-backend/3-photos/
aws s3 cp ./green-screen-test.png s3://$UPLOAD_BUCKET
