Is your request related to a problem? Please describe.

There are two ways in the self manage node groups main.tf file, which can be used to specify the size of the volume for a node group.

1. Method 1: disk_size

2. Method 2: block_device_mappings

After looking at the node_groups.tf and self_managed_node_group module file. I am assuming that it is not being used anywhere.

Secondly, in method 1 I don't have options to change volume specifications i.e encryption, volume type, etc.

I have 2 questions:

1. What is the purpose of disk_size?
2. if we can create a volume using the block_device_mappings param then is it necessary to keep disk_size in the example because it is causing confusion?

Describe the solution you'd like.

I think only 1 method should be used to specify the size of the volume because only disk_size doesn't provide much flexibility.

Describe alternatives you've considered.

I think this might be a copy+paste error in the example. disk_size is only available for EKS managed node groups - let me investigate and double check

@bryantbiggs sure. Another suggestion:

It would be good to add this in the examples provided.

The use of disk_size in examples was updated in #2034
