'npx cdk destroy' failed because ENI was in use

[alexeyshishkin01]

Hello, everyone !

My command 'npx cdk destroy' failed because ENI was in use during the deletion.

So I had to manually delete ENI, then subnet, then VPC, then Cloud Formation stack.

Could you pls. have a look at the code to fix the issue ?

best regards Alexey Shishkin

Does the force option help?

npx cdk destroy --all --force

[alexeyshishkin01]

I don't know. To test this option I have to launch the solution again and try to destroy it.

Is it possible to update the documentation https://aws-samples.github.io/aws-genai-llm-chatbot/guide/deploy.html#clean-up with this option ?

Just did a full deployment with each model and RAG. When I went to destroy, two resources were marked as deleted but in fact not actually delete.

1. Sagemaker Endpoint (IDEFICS)
2. VPC Endpoint (shared vpc)

No solution in cdk yet, just stating I'm seeing the same thing. I had to go and find through through resources in cloudformation stack, delete them manually, then go back to cloudformation to complete the deletion.

npx cdk destroy --all --force

It looks like it does not help as well:

The subnet has an ENI which is not deleted. The ENI Description is 'SageMaker managed ENI for endpoint amazon-FalconLite instance i-03b16c72c5b18266d'

[alexeyshishkin01]

these commands can be helpful for the troubleshooting:

aws ec2 delete-network-interface --network-interface-id $(aws ec2 describe-network-interfaces --filters "Name=description,Values=SageMaker managed ENI for endpoint amazon-FalconLite" --query 'NetworkInterfaces[].NetworkInterfaceId' --output text)

aws ec2 delete-subnet --subnet-id $(aws ec2 describe-network-interfaces --filters "Name=description,Values=SageMaker managed ENI for endpoint amazon-FalconLite" --query 'NetworkInterfaces[].SubnetId' --output text)

[alexeyshishkin01]

as a workaround one can run the following in the script:

npx cdk destroy --all --force aws ec2 delete-network-interface --network-interface-id $(aws ec2 describe-network-interfaces --filters "Name=description,Values=SageMaker managed ENI for endpoint amazon-FalconLite" --query 'NetworkInterfaces[].NetworkInterfaceId' --output text) aws ec2 delete-subnet --subnet-id $(aws ec2 describe-network-interfaces --filters "Name=description,Values=SageMaker managed ENI for endpoint amazon-FalconLite" --query 'NetworkInterfaces[].SubnetId' --output text) npx cdk destroy --all --force

it looks like it's an old issue in AWS - https://stackoverflow.com/questions/52416454/sagemaker-model-cloudformation-stack-deletion
