Terraform configs for spinning up and down Linode infrastructure
Install Terraform:
brew install terraform
Create a file terraform.tfvars. Each variable declared in variables.tf should be defined here using the following syntax:
access_token = "aasfgawe34teargaa..."
The only variable that is required is your Linode API access token. The other values have defaults that will be used if you don't specify, but this is the easiest way to customize the # of Linodes, Volumes, etc. that are produced.
Before running for the first time, run:
terraform init
This should install the Linode provider and any other dependencies.
Check the plan:
terraform plan
Review the console output; if there are no errors and the displayed plan looks good, run:
terraform apply
To tear down your infrastructure, use:
terraform destroy
To update e.g. the number of Linodes deployed, alter the relevant variable (in this case web_count). Then run
terraform apply again; Terraform will bring your Linode account's state in line with the updated plan.
