#terragrunt - June 2021

Anyone feel like sharing some terragrunt insight? I have a solid project design using the 4 layers structure from Cloudposse but i'm confused on why all of a sudden my terragrunt isn't detecting changes.

Also, would love to see more examples of structure in terragrunt, if anyone combines multiple modules into one hcl file (with a tf file in the same directory?) if it would simplify things over 1 hcl = one remote module each time instead of a composite of a couple. I get i can use dependencies for that, but it does add some complication when dealing with running directories in order at times.

I'm dealing with a full buildout of all layers and if not for the clean input structure and lack of need to duplicate all my variable files from modules, I'd sure love native terraform. Terragrunt can be tricky to debug. However, the benefit of a clean terragrunt directory is pretty clear when I need to reproduce my prod deployment

I've never used configured terragrunt to use an SSH key that wasn't my default key. What is a sane way to set this up on a linux environment without mangling the URL committed to the repo? ( Which is what happens when the .ssh/config file is used to manage which SSH key is used when git is called. )
