Docker - in CI/CD

What is a key benefit of using Docker layer caching in a CI pipeline?

AIt increases the size of the final Docker image

BIt removes all intermediate build files automatically

CIt disables parallel builds in the pipeline

DIt speeds up build times by reusing unchanged layers

Step-by-Step Solution

Solution:

Step 1: Understand Docker layers in CI
Docker images are built in layers, and caching allows reuse of layers that haven't changed.
Step 2: Identify the benefit of caching
Reusing layers avoids rebuilding unchanged parts, which speeds up the build process.
Final Answer:
It speeds up build times by reusing unchanged layers -> Option D
Quick Check:
Docker layer caching benefit = Speed up builds [OK]

Quick Trick: Cache unchanged layers to build faster in CI [OK]
