Docker - in CI/CD

In a GitHub Actions workflow, what will happen if you run this step?

run: docker run --rm myimage ls /app

Assuming 'myimage' exists and '/app' folder is inside the container.

AStarts container but does not show output

BDeletes the /app directory

CLists files inside /app directory

DFails because --rm is invalid

Step-by-Step Solution

Solution:

Step 1: Understand docker run with --rm
The '--rm' flag removes the container after it exits, it does not affect command output.
Step 2: Understand 'ls /app' command
This lists files inside the /app directory in the container.
Final Answer:
Lists files inside /app directory -> Option C
Quick Check:
docker run --rm lists files = A [OK]

Quick Trick: --rm cleans container after exit, output still shows [OK]
