Tfvars & Layering
Note: Premium video content requires a subscription.
Terraspace supports looking up tfvar files in conventional locations. This encourages an organized structure.
Tfvars Structure
Tfvar files should be place within the app/stacks/MOD/tfvars folder. Example:
app/stacks/demo
├── main.tf
├── tfvars
│ ├── base.tfvars
│ ├── dev.tfvars
│ └── prod.tfvars
└── variables.tf
You don’t have to specify the -var-file option, the tfvars files are automatically processed and used via layering.
Layering
The 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
Seed Command
The terraspace seed command creates starter tfvars files for you. Examples:
$ terraspace seed network
create app/stacks/network/tfvars/dev.tfvars
$ TS_ENV=prod terraspace seed network
create app/stacks/network/tfvars/prod.tfvars
$
