Manually Cleaning Terraform Related Instances

AWS cleaning resources

If the deployment process was previously successful, you can run bin/infra destroy. Additionally, bin/infra destroy_setupwill delete the DynamoDB table. More information on destroying infrastructure is available here.

However, in circumstances that rely on insufficient AWS account rights, the deployment process may fail. In this case, bin/infra destroy_setup will not work.

Additionally, forgetting to clean resources can result in high AWS costs in a short period of time, so it's best to check that all resources have been removed.

In order to completely manually remove Terraform deployment from AWS you need to clear all related instances of the following services:

  • S3
