Research

To perform this task, I have researched some documentation and tutorial that may help:

Besides, the first link builds a dockerized project using Angular as the frontend, so maybe it would be useful in the future to dockerize the backend, but using Ionic Framework instead.

Development

While following the tutorial, I faced several problems.

:red_circle: After configuring the Django API and the PostgreSQL database, I got the error: Error Could not translate host name "db" to address: Name or service not known

This error was displayed after executing the docker compose up command. After searching some related problems, and trying some proposed solutions in this post, the error kept displaying.

:heavy_checkmark: The solution that fixed the problem was related to the initialization of the database. Following the second tutorial, adding the `POSTGRES*` environment variables.

environment:
      - POSTGRES_DB=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres

The log of the docker compose command is:
