3. terraform apply

Expected Behavior

terraform apply output
No changes. Your infrastructure matches the configuration.

when I change the resources block to

          resources {
            limits = {
            }
            requests = {
            }
          }

it works as expected

Hello @dsoyet ! Thank you opening this issue, like you stated in your comment the resources block needs to have the attributes set in order for any change to happen since it is expecting some sort of value to be provided.

Hello @BBBmau I think it is a bug, just like #754. How a user know "the resources block needs to have the attributes set" ?
