Terraform Workspaces

Abstract

Studies on Terraform Workspaces with Docker provider.

Setup

  • Create directory.
  • Initiate terraform with kreuzwerker/docker provider.
  • Create workspaces-
  • Create as many workspaces .tfvars files.
  • Create a variable.tf file.
  • Export a env var TF_WORKSPACE to be used with plan/apply.

Usage

  • Define env_prefix variable in .tfvars and variable.tf vars.
  • Call tf apply command with workspace env var for tfvars file. Ex: tf apply -var-file=$TF_WORKSPACE.tfvars -var-file=globals.tfvars --auto-approve

Using multiple workspaces with multiple aws accounts.

Building a scenario to test workspaces with AWS multiple accounts

Mock AWS with Localstack

  • Prepare docker-compose.yaml with as many localstack instances you need. Attention to change the port mapping for external env for avoind conflict. Example in here in repo.
  • Run the docker compose build + up. Ex: docker-compose up -d --build

Validate

  • aws ec2 describe-vpcs --profile dev --query "Vpcs[*].[VpcId,IsDefault]"
