What did you expect to happen?

efs environment for lab to be created successfully

How can we reproduce it?

1. go to https://www.eksworkshop.com/docs/fundamentals/storage/efs/ (after creating the environment as explained in: https://www.eksworkshop.com/docs/introduction/setup/your-account/using-eksctl).
2. execute this in the online lab environment VS-code prepare-environment fundamentals/storage/efs

Anything else we need to know?

The previous EFS-lab sections like Amazon EBS prepare-environment went fine , as well Ingress, Load Balancers etc

EKS version

1.30

I am also experiencing this same issue as @justRishi described above.

Thanks for the report, we'll need to look in to this. The IAM permissions look like they should allow this and our tests are succeeding so it will take some manual investigation.

same issue for me

Same issue for me. Tested yesterday on eu-west-1 (failed) but works today on us-west-2

[rdripps]

I spent some time troubleshooting this and was able to resolve this by adding the following.

In the
eks-workshop-ide-ec2 policy
add
ec2:CreateNetworkInterface
ec2:DeleteNetworkInterface

Based on the AWS CLI documentation the following permissions are required.

This operation requires permissions for the following action on the file system:

elasticfilesystem:CreateMountTarget
This operation also requires permissions for the following Amazon EC2 actions:

ec2:DescribeSubnets
ec2:DescribeNetworkInterfaces
ec2:CreateNetworkInterface

Hope this helps..
I would create PR but not sure how AWS manages public input.
