Docker Issues

• Clean Docker Environment: Sometimes, Docker can cache images or configurations that cause repeated errors. To ensure a fresh environment, the following Docker commands can be used to clean up:
  1. docker kill $(docker ps -q): Stops all running containers.
  2. docker rm $(docker ps -aq): Removes all containers.
  3. docker system prune --volumes -f: Removes all stopped containers, unused networks, images, and optionally, volumes.
  4. docker volume rm $(docker volume ls -q): Removes all unused volumes.

Problem Statement: Docker build fails due to psycopg2 issue

While attempting to build a Docker image, the process fails when trying to install the psycopg2 package, indicating that pg_config is missing. The user has verified that the requirements.txt matches the one provided in the TDD lab, yet the issue persists.

Solution:

Update Dockerfile to include RUN apt-get update && apt-get install -y postgresql-client on Line 23 which are required to build the psycopg2 package.

Alternatively, switch to using the binary package psycopg[binary] to avoid the need for compiling the package and installing additional dependencies.
