Is it possible to place all project components inside a single container?

It is technically possible to place all project components inside a single container, but this is not considered best practice.

If the project has multiple services or components (for example, a web server, database, cache), each is usually run in a separate container. This provides:

• Isolation of components
• Ease of scaling
• Simplicity of updates and debugging

However, for simple or small projects, you can package everything into one container to simplify deployment. But in such cases:

• The container will be heavier and more difficult to maintain
• It will be harder to scale individual parts

Ultimately, it is recommended to use a multi-container approach (for example, with Docker Compose), where each component runs in its own container.
