Lab — Persist MongoDB Data with Docker Named Volumes

Working branch: main

The seed script already exists and works.

Your task is the Docker setup and persistence configuration.

Real-World Scenario

The backend team already has a MongoDB database running locally on developer machines.

The DevOps team now wants to standardize the environment using Docker so:

• Every developer uses the exact same MongoDB version
• CI pipelines use the same database setup
• New developers can start quickly
• Seed data is automatically available

At first, MongoDB works correctly inside Docker.

Then developers discover a major issue:

Every time the MongoDB container is removed, all database data disappears.

Your task is to redesign the setup so database data survives container removal.

You must investigate:

• How container storage works
• Why container data disappears
• How named volumes solve persistence problems
• How MongoDB initialization works
