How can I optimize my Docker build cache?

To optimize your Docker build cache, you can start by organizing your Dockerfile to minimize changes that invalidate the cache.

What are some best practices for structuring my Dockerfile?

Some best practices include grouping commands that change less frequently, using multi-stage builds, and leveraging the .dockerignore file.

Can you explain multi-stage builds?

Multi-stage builds allow you to use multiple FROM statements in your Dockerfile, enabling you to copy only the necessary artifacts to the final image.

How does the .dockerignore file help with caching?

.dockerignore prevents unnecessary files from being sent to the Docker daemon, which can help keep your build context small and improve cache efficiency.
