What are some techniques to optimize a Dockerfile?

To optimize a Dockerfile, you can use techniques like minimizing layers, using multi-stage builds, and leveraging caching.

Can you explain how multi-stage builds work?

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.

What are the benefits of minimizing layers?

Minimizing layers reduces the image size and improves build performance, as fewer layers mean less overhead during image creation.

Are there any best practices for using caching?

Yes, you should order your commands from least to most likely to change, as this maximizes cache hits and speeds up builds.
