What is the difference between using cache and no-cache in Docker?

Using cache in Docker allows you to reuse layers from previous builds, speeding up the build process. No-cache forces a fresh build.

When should I use no-cache?

You should use no-cache when you want to ensure that all layers are rebuilt, which is useful for debugging or when dependencies change.

Does using cache affect the final image size?

Not directly. Caching affects build speed, but the final image size depends on the layers included, regardless of caching.

Can I control caching behavior in my Dockerfile?

Yes, you can control caching by structuring your Dockerfile wisely, using specific commands, and leveraging build arguments.
