Multiple Environments with Layering

You can use Terraspace to easily create multiple environments with the same infrastructure code. This is thanks to Terraspace Layering. We’ll walk through an example to help understand how it works.

Creating Multiple Environments

To create multiple environments like dev and prod just change TS_ENV. Example:

TS_ENV=dev  terraspace up demo
TS_ENV=prod terraspace up demo

Different tfvar files will be used for different environments.

Tfvars Structure

Tfvar should be place within the app/stacks/MOD folder. Example:

├── tfvars
│   ├── base.tfvars
│   ├── dev.tfvars
│   └── prod.tfvars

You don’t have to specify the -var-file option, the tfvars files are automatically processed and used via layering.

The tfvar files are processed and “layered”. Example:

TS_ENV=dev  terraspace up demo -y # merges base and dev
TS_ENV=prod terraspace up demo -y # merges base and prod

You can use the same infrastructure code with different variables to create different versions of your environments easily.
