Cleaning Up after the Workshop

Here are high level instructions on cleaning up after you have completed the workshop.

1. Delete CloudFront Origin Access

The CloudFront origin access identity is still being used, hence, we need to delete the AssetsBucketOriginAccessIdentity manually first. Go to CloudFront and select your CloudFront Distribution. Go to Origins and Origin Groups and delete the Origin Group and Orgin that you created.

2. Delete API Gateway

Go to Custom Domain Names in API Gateway in Singapore and select your *.<MYSUBDOMAIN>.multi-region.xyz domain name. Click x button to delete it.

3. Delete Aurora Read Replicas

You created the Aurora Read Replica in Singapore using CLI. Go to RDS console, select Read Replica Cluster arc309-replica-cluster, and select Promote in Actions. We need to promte the read replia as standalone to delete the instance. Then select Read Replica Instance arc309-replica-instance and select Delete in Actions. In the deletion window, uncheck Create snapshot, check acknowledgement, type delete me, and click Delete.

4. Delete S3 buckets and S3 Replication role

You need to empty the S3 bucket to delete resources. Go to S3 console and delete workshop related buckets:

  • cdktoolkit-stagingbucket-xxxxxxx in Singapore and Ireland
  • bookstore bucket in Singapore and Ireland
  • pipeline bucket in Ireland

Go to IAM and delete S3 replication role such as bookstore-S3replicationRole.

5. Delete Route 53 Record Sets and Health Check

Go to Route 53, select your Hosted Zones, select all your Record Set, and Delete Record Set. Select Health Checks and delete existing Health Checks for Ireland and Singapore.

6. Delete CloudFormation stacks

You deployed 5 CloudFormation stacks in Ireland and 3 stacks in Singapore during the workshop.

The stacks must be deleted in the following order:

  1. MyBookstoreSingapore stack - Workpress-Secondary - CDKTookit in Singapore
  2. MyBookstoreIreland stack - Workpress-primary - hostedZone - CDKTookit - aws-cloud9 in Ireland (You can only delete the MyBookstoreIreland stack 24 hours later after you added the DyanmoDB Global Table)

To delete Cloudformation stacks, go to CloudFormation in the specific region, select the stack name and click Delete button. The template will delete along with all resources it created.
