Problem Statement

In AWS we have seen an user trying to mount EFS as part of deploying appsmith getting the following error:

ResourceInitializationError: failed to invoke EFS utils commands to set up EFS volumes: stderr: Failed to resolve "fs-01bd17a53b98b8014.efs.eu-west-1.amazonaws.com" - check that your file system ID is correct, and ensure that the VPC has an EFS mount target for this file system ID. See https://docs.aws.amazon.com/console/efs/mount-dns-name for more detail. Attempting to lookup mount target ip address using botocore. Failed to import necessary dependency botocore, please install botocore first. : unsuccessful EFS utils command execution; code: 1

The root cause :
In aws ecs. Users can mount EFS only via the DNS and not via IP and the user had DNS resolution disabled in the VPN.

Use Cases / User query reference

To avoid this confusion. It will be good if we add a statement under
Before you Begin section
like follows
Please make sure dns-resolution is enabled in your VPC
