In this repo, i give example how to dealing with multiple environment when using terraform as your IaC.

What this repo is made of

• Terraform workspace
• Terraform interpolation (lookup)
• Makefile

➜ terraform-multienv $ tree
.
├── map
│   ├── main.tf
│   ├── terraform.tfstate.d       => workspace state file location
│   │   ├── dev
│   │   ├── prod

    │   └── staging
    └── variables.tf

10 directories, 9 files

There are 2 examples scenario when dealing with terraform for multiple environment

• in this directory i use resources mapping based on the environment in variables.tf
• using lookup function to get correct value based on environment and store it in local

• in this folder I separate values based on variable file

  dev.tfvars

  staging.tfvars

  prod.tfvars

• create Makefile as a wrapper for executing terraform command

Please try and find it by yourself :D
