This code shows an example of live Terraform environment pattern, where all applications in all environments are keeped separately in tree-defined structure.
Symlinks and Makefiles are used to reduce amount of copy-pasta and automation.
This pattern allows us to me
Deploys several EC2 instances in two AZs into newly created VPC to both environments.
Things to consider:
- managing symlinks and Makefiles are very error-prone
- still lot of duplicated Terraform code
- lack of orchestration, need to manage dependencies manually
