hard📝 Workflow Q8 of 15

Docker - in CI/CD

APull the cache image before build, then use --cache-from with that image

BBuild the image first, then push it to the registry

CUse --no-cache option to force cache usage

DDelete local images before build to avoid conflicts

Step-by-Step Solution

Solution:

Step 1: Pull cache image from remote registry
Pulling the cache image locally makes cached layers available for reuse.
Step 2: Use --cache-from option with the pulled image
This tells Docker to use the pulled image layers as cache sources during build.
Final Answer:
Pull the cache image before build, then use --cache-from with that image -> Option A
Quick Check:
Pull cache + --cache-from = reuse layers [OK]

Quick Trick: Pull cache image first, then build with --cache-from [OK]

Common Mistakes:

Using --no-cache disables caching
Pushing image before build doesn't help cache reuse
Deleting images removes cache
