Docker - Image Optimization

Consider this Dockerfile snippet:

FROM gcr.io/distroless/base
COPY app /app
CMD ["/app"]

If the application at /app crashes immediately after starting, what will be the container's behavior?

AThe container will restart automatically and provide a shell for debugging

BThe container will exit immediately with no interactive shell available

CThe container will stay running and print logs to the console

DThe container will open a shell prompt for manual intervention

Step-by-Step Solution

Solution:

Step 1: Analyze distroless behavior
Distroless images do not include shells or interactive tools, so no shell prompt is available.
Step 2: Understand container lifecycle
If the app crashes immediately, the container process exits, causing the container to stop.
Final Answer:
The container will exit immediately with no interactive shell available -> Option B
Quick Check:
Crash causes container exit; no shell in distroless [OK]

Quick Trick: Distroless containers exit on crash; no shell for debugging [OK]
