Docker - Image Optimization

Why does BuildKit improve Docker build caching compared to the traditional builder?

ABecause it supports fine-grained cache mounts and parallel step execution

BBecause it disables all cache to ensure fresh builds

CBecause it uses a single large cache for all builds

DBecause it requires manual cache management by the user

Step-by-Step Solution

Solution:

Step 1: Understand BuildKit caching improvements
BuildKit allows cache mounts for specific directories and runs steps in parallel, improving cache use.
Step 2: Evaluate other options
BuildKit does not disable cache, does not use a single large cache, nor require manual cache management.
Final Answer:
Because it supports fine-grained cache mounts and parallel step execution -> Option A
Quick Check:
BuildKit caching = fine-grained + parallel steps [OK]

Quick Trick: BuildKit caching is smarter and parallel [OK]
