Source Code & Environments

The Source Code

The source code of the project is hosted in the gitlab at below URL. The backend code is in the aicamera_backend directory.

AI Camera Source Code

Below are the technologies and libraries used in development and maintenance of the application.

  • Python API library: Flask
  • Database: Postgres SQL server
  • ORM: SQL Alchemy
  • DB Migrations: alembic
  • Deployment: Docker services using docker-compose

Alembic

The Alembic library is used to manage database schema changes on various environments. Below are sample commands to automatically generate migration files and to perform database upgrades or downgrades.

cd aicamera_backend
export DATABASE_URL=postgresql://aicamera_user:camcom1616@localhost/aicamera

alembic revision --autogenerate -m "test"
alembic upgrade head # applies all the migrations on the database

alembic downgrade -1 # downgrades the last database migrations

Environments and Deployments

We have multiple environments configured to meet different requirements.

The deployment process involves building a Docker image, pushing it to Docker Hub, pulling it onto the target VM, and restarting the relevant Docker services using Docker Compose commands.

Below are the details of the deployment commands for each environment, along with the corresponding details of build VM and environments.
