Storing modules remotely
We've stored the application module in the very same directory where our main Terraform template resides. It makes it impossible to reuse: if there is a new application in the company that requires the same infrastructure (meaning the same module), then we cannot easily use it.
Remember the source
attribute of the module?
module "mighty_trousers" { source = "./modules/application"
Well, it turns out that it doesn't have to be a path to a local directory. In fact, there are multiple supported sources for modules:
- GitHub
- BitBucket
- Generic Git and Mercurial repositories
- HTTP URLs
- S3 buckets
Storing modules in one of these destinations allows us to have a collection of reusable components. We can even version our modules, just like system packages or programming language libraries.
As we are deep into GitLab already, let's create yet another repository and call it packt-terraform-app-module
. As always, all the code written in this chapter is available on GitLab at https:/...
