How can I optimize Docker image caching in CircleCI?

You can optimize Docker image caching in CircleCI by using the caching feature to store your Docker layers. This reduces build times.

What specific steps should I take to implement caching?

First, define a cache key in your CircleCI config file. Then, use the docker executor and specify the cache paths for your images.

Are there any best practices for managing cache size?

Yes, regularly clean up unused images and layers, and consider setting a maximum cache size to prevent excessive storage use.

Can I cache dependencies as well?

Absolutely! You can cache dependencies by specifying their paths in the cache configuration, which will speed up your builds.
