Spring Boot - Docker and Deployment

How can you combine multi-stage Docker builds with caching to speed up Spring Boot builds?

ARun all commands in a single stage to avoid cache invalidation

BSeparate dependency download in an early stage and copy only dependencies if unchanged

CUse multiple FROM instructions without naming stages

DAlways delete the Docker cache before building

Step-by-Step Solution

Solution:

Step 1: Understand caching in Docker builds
Docker caches layers; if dependencies don't change, they can be reused.
Step 2: Apply caching with multi-stage builds
Downloading dependencies in an early stage and copying them only if unchanged speeds up builds.
Final Answer:
Separate dependency download in an early stage and copy only dependencies if unchanged -> Option B
Quick Check:
Cache dependencies early to speed builds [OK]

Quick Trick: Cache dependencies separately to avoid repeated downloads [OK]
