Modules | Terraform Tutorial | #15

Modules group multiple resources together to create reusable code throughout your configurations. Modules can be thought of like packages in Python or modules in Javascirpt. A developer calling a module doesn't need to know about the underlying behavior and needs to only pass in the required data.

In this video tutorial I'll go over how and when to create modules along with some best practices.

- Root and child modules
- Output values from modules
- Use output values as inputs to other modules or resources
- Meta arguments like source and version
- Folder architecture for designing modules
- count, for_each and depends on in Terraform version 0.13
- One module that can use multiple providers

This is exactly what I was looking for. The other videos approached the topic in such a complicated way that by the end I didn't feel like watching it anymore.
Great work. Keep it up ;)

when I searched for terraform modules, this video came out as number 1, I was wondering why, but now I know why...this is hands down the best TF module explanation video on youtube.
Some quick tips, for aligning the equals, you can use terraform fmt, also for seeing output values without running apply, you can use terraform refresh.

@Will Brock - Great videos. Keep up the good work. I have noticed that you align the "=" signs. Just one tip. I usually use "terraform fmt" at the command line to align them.
