Using Dynamic Blocks in Terraform
Some resources in Terraform can have multiple instances of the same nested block. For instance, the virtual network in Azure or the tags in an AWS auto-scale group. Instead of creating each block by hand, you can use dynamic blocks and a for_each argument. I don't love the solution for reasons I discuss in the video, but I'm a pragmatist at heart. Sometimes good enough is good enough.
