Terraform Nested For Loop Map

Then we nestedly loop through the 3 lists to form a dictionary object, which has the information for the target group. Funnily enough i noticed yesterday that the links to that flatten example and the setproduct example were both a bit buried in the documentation (just a passing remark in the using expressions for for_each section) and so i pushed up an edit that makes them a bit more prominent.that’ll show up in the published documentation with the. For example, to grant multiple permissions for myself on a snowflake schema, i could do something like this:

Though it performs looping, its primary purpose is really for manipulating data structures. » flattening nested structures for for_each the resource for_each and dynamic block language features both require a collection value that has one element for each repetition. The other requirement we need to meet for this to be for_each compatible is to assign each element a unique key, and there isn't typically a rule that child names must be unique across all parents so i expect we'll need to produce a compound key from name and parent_name in order to meet that requirement:

This article distills these details into patterns you.

This is how the below script looks like and it is smaller and easier. This is terraform’s oldest, simplest, and most limited iteration construct: It’s a natural fit since we don’t have to do any toset conversion. Region => { for cert in certs :
