What are some effective Docker cache strategies?

Effective Docker cache strategies include using multi-stage builds, leveraging build arguments, and optimizing layer ordering.

Can you explain how multi-stage builds help with caching?

Multi-stage builds allow you to separate build dependencies from the final image, reducing size and improving cache efficiency.

What about using build arguments? How does that work?

Build arguments let you pass variables at build time, allowing you to customize layers and potentially reuse cached layers.

Are there any best practices for layer ordering?

Yes, place less frequently changing commands at the top of your Dockerfile to maximize cache hits for more stable layers.
