sample code to create a custom terraform backend

terraform-backend-sample

A sample python wsgi module to implement a custom Terraform backend

Running

• create a virtual env python3 -m virtualenv venv
• activate your virtual env . venv/bin/activate
• install required packages into your virtual env pip install -r requirements.txt
• test with pytest pytest . -v
• run with gunicorn or uwsgi uwsgi --ini dev.ini
• once uwsgi is running on 9090, you can go to terraform/example and run ./run.sh. This will require terraform to be installed.
• DO NOT USE WITH PRODUCTION INFRASTRUCTURE
• terraform side, in a sample repo (NOT PRODUCTION), configure backend.tf to point to your running instance

terraform {
    backend "http" {
        address = "http://localhost:9090/get/department/product/environment.tf"
        lock_address = "http://localhost:9090/lock/department/product/environment.tf"
        unlock_address = "http://localhost:9090/unlock/department/product/environment.tf"
        # basic auth
        # username =
        # password =
    }
}

Customizing

• in this sample application, the data is stored in memory and is lost when the process is closed, so redirect calls to a database
• add security with user/password passed in basic auth
• add ssl
