Answer from AI
The following approaches are used to minimize overhead when using virtualization in Docker:
- Using lightweight base images — for example, Alpine Linux, which is significantly smaller in size than standard images.
- Multi-stage builds — allow reducing the final image size by excluding unnecessary files and dependencies.
- Layer caching — Docker caches layers so that unchanged parts are not rebuilt during subsequent builds.
- Optimizing Dockerfile — combining RUN commands, minimizing the number of layers.
- Using volumes to store data outside the container to avoid increasing the image size.
- Resource limits for containers (CPU, memory) to prevent excessive consumption.
These methods help speed up container startup, reduce disk space usage, and improve overall efficiency with Docker.
