Terraform Collection Functions Explained | concat, flatten, zipmap, setproduct, matchkeys
Collection functions are not utilities. They are a data shaping layer that determines whether your Terraform configuration behaves predictably or fails silently.
This lesson breaks down how Terraform transforms raw input into deployable structures using core collection functions.
You will learn:
How concat combines multiple input sources into one iterable list
Why flatten is required before looping over nested data
How compact and distinct prevent unintended resource creation
Why zipmap converts unstable lists into stable resource keys
How setproduct expands combinations across environments and services
How matchkeys filters aligned data structures safely
The pipeline approach to preparing data for for_each
Lesson 78
