Project for exploring TFCDK

Up and running

First, you need to setup the necessary environment variables on Terraform cloud.

Then install pipenv as package management, for installing the dependencies:

pipenv install

Run synth command to verify if the source code is ready.

cdktf synth

Start deploy the infrastructure

cdktf deploy --auto-approve

Clean up command if no longer in use.

cdktf destroy --auto-approve
