LPI Exam 701-100 Topic 11 Question 54 Discussion

Actual exam question for LPI's 701-100 exam

Question #: 54
Topic #: 11

Given the following excerpt of a Dockerfile:

Run apt-get --y update && apt-get install --y fortunes && apt-get clean

Why are the multiple apt-get commands combined in one RUN statement instead of using multiple RUN statements?

ATo prevent the commands from running in parallel because Docker executes all RUN statements in their own container at the same time.

BTo ensure the execution order of the commands because Docker might evaluate the statements of a Dockerfile in any order.

CTo avoid the creation of unnecessary images because Docker creates a new image for each RUN statement.

DTo execute both commands in the same container instance and void Docker to reset the container to the original base image.

ETo execute the apt-get install command only if the apt-get update command was successful because Docker does not check the success of RUN statements.

I bet the folks who wrote this question are just waiting for someone to say 'apt-get install fortune-cookies' as the answer. That would be a real knee-slapper!

Alright, let's see here. I think the key is understanding how Docker handles RUN statements and image layers. Time to put on my thinking cap!

Hmm, this is a good one. I wonder if the folks who wrote this question have a sense of humor. Maybe they'll throw in a joke about 'apt-get install fortune-cookies' or something.

But wouldn't combining the commands in one RUN statement reduce the number of images created?

Haha, I bet the folks who wrote this question were trying to trip us up. But I'm pretty sure the right answer has something to do with efficiency and avoiding unnecessary image layers.
