Terraform Dynamic Block

Why are dynamic blocks ?

• Dynamically constructs repeatable nested configuration blocks inside Terraform resources.

• Supported within the block types:

  • resource

  • data

  • provider

  • provisioner

• Use to make your code cleaner

How to configure Dynamic Blocks

• Dynamic blocks expect a complex variable type to iterate over.

• It acts like a for-loop and outputs a nested block for each element in your variable.

CAUTION

• Be careful not to overuse dynamic blocks in your main code, as they can be hard to read and maintain

• Only use dynamic blocks when you need to hide details in order to build a cleaner user interface when writing reusable modules.
