Demo application

This repository contains a demo application (a simple echo web service) including containerization, orchestration, IaC and CI/CD code.

Running locally

Debug & develop

First install Pipenv, then go to the app directory and issue the following command:

pipenv install --dev

Then you may either run the application using the included VS Code launch configuration or the following command:

pipenv run flask --app flaskr.app run

Docker image

You may either build and run the Dockerfile contained in the app directory, or use docker-compose up.

Infrastructure-as-Code

The terraform directory contains the definition of contents of a common environment and a full definition of the development environment. Terraform state is kept in the common environment, represented by the common resource group on Azure, in a blob storage container. That resource group along with the storage account and the container were created manually.

Each environment is represented by a directory inside terraform/envs. These represent the root modules, which other modules from the terraform directory. All terraform commands should be invoked from one of those directories.

In a fresh deployment, the common infrastructure needs to be applied first, as other environments depend on it.

NOTE: Only the development environment is included in this demo.
