Cleaning up the Chalice application

This part of the tutorial provides instructions on how you can clean up your deployed resources once you are done using this application. This set of instructions can be completed at any point during the tutorial to clean up the application.

Instructions

  1. Delete the chalice application:

    $ chalice delete
Deleting Rest API: kyfn3gqcf0
Deleting function: arn:aws:lambda:us-west-2:123456789123:function:media-query-dev
Deleting IAM role: media-query-dev-api_handler
Deleting function: arn:aws:lambda:us-west-2:123456789123:function:media-query-dev-add_video_file
Deleting IAM role: media-query-dev-add_video_file
Deleting function: arn:aws:lambda:us-west-2:123456789123:function:media-query-dev-handle_object_removed
Deleting IAM role: media-query-dev-handle_object_removed
Deleting function: arn:aws:lambda:us-west-2:123456789123:function:media-query-dev-handle_object_created
Deleting IAM role: media-query-dev-handle_object_created

  2. Delete all objects in your S3 bucket:

    $ aws s3 rm s3://$MEDIA_BUCKET_NAME --recursive
delete: s3://media-query-mediabucket-4b1h8anboxpa/sample.jpg
delete: s3://media-query-mediabucket-4b1h8anboxpa/sample.mp4

  3. Delete the CloudFormation stack containing the additional AWS resources:

    $ aws cloudformation delete-stack --stack-name media-query

Validation

  1. Ensure that the API for the application no longer exists:

    $ chalice url
Error: Could not find a record of a Rest API in chalice stage: 'dev'

  2. Check the existence of a couple of resources from the CloudFormation stack to make sure the resources no longer exist:

    $ aws s3 ls s3://$MEDIA_BUCKET_NAME
An error occurred (NoSuchBucket) when calling the ListObjects operation: The specified bucket does not exist

$ aws dynamodb describe-table --table-name $MEDIA_TABLE_NAME
An error occurred (ResourceNotFoundException) when calling the DescribeTable operation: Requested resource not found: Table: media-query-MediaTable-YIM7BMEIOF8Y not found
