There are a lot of complicated explanations out there on how to do loops / for_each loops using Terraform. You nailed it beautifully. Thank you.

I like your tutorials, well explained, good speaking and pronunciation, not long videos, thank you!

I want to point out that you should use count as little as possible, especially on resource creation. If you have resource A, B, C, D, that will give you resources 0, 1, 2, 3. If B is then no longer needed, C slides into the "1" slot and D into the "2" slot. This is a huge pain. It will try to force resource recreation, which is fixable, but working around this isn't worth it. Just use for_each and reference the resource index by name. The resources need to be a set or map, but you can convert a list of strings with toset().

Thank you for a very wonderful presentation. However, my question is, since both the for_each and count produce the same results on AWS, am interested in knowing the difference and why should I prefer one over the other? Thank you very much!

thank you for your knowledge sharing! You make a great work!

Great post thank you. Also I found out that 'count' is a parameter of terraform, it cannot be anything else. Having this parameter in the block executes the block 'x' number of times specified in count.

Hi Rahul,

thanks but how can test the out value of the functions some times locally

HavingFunWithAvyan

hi rahul you have given count = length(var.user_names) iam littile confusing over here, are you calling another file which you have mentioned already as var.user_names somewhere?
