################################ Overview

# This Dockerfile builds an Adala environment.
# It consists of three main stages:
# 1. "base-image" - Prepares common env variables and installs Poetry.
# 2. "venv-builder" - Prepares the virtualenv environment.
# 3. "prod" - Creates the final production image with the Adala source and its venv.
