Thanks, i'll try this.

@scshitole Would you be able to provide a version targeted for 0.12? It seems that the new for loop functionality would really come in handy here.

[dannyk81]

release v0.12.3 is out (https://github.com/terraform-providers/terraform-provider-bigip/blob/v0.12.3/CHANGELOG.md#0123-june-06-2019) and includes support for 0.12

[vjvalenti2]

Yes, I am aware. We are building an Big-IP configuration from scratch so it would be very helpful to take advantage of some of 0.12's new features like dynamic blocks and for loops. But I haven't yet seen any working examples of such with this provider.

How can we for example generate dynamic blocks of node resources from a list of node names?

[vjvalenti2]

Nevermind - I now see that for/for_each does not (yet) apply at the resource level, so I went with the old count method.
