When writing Dockerfiles, the order of your Dockerfile instructions determines how long the build will take after updating any of the commands. Do you understand how to make the most efficient Dockerfiles?

Drag the items below into order

Instructions

Order the Dockerfile instructions to the order in which you are most likely able to re$-$use as many cached layers as possible.

From how we typically work, we know that the packages we need for our pipeline, defined in requirements.txt$,$ change less often than the python code in

pipeline.py $.$

COPY $/$app$/$requirements$.$txt $/$app$/$requirements$.$txt

COPY $/$app$/$pipeline$.$py $/$app$/$pipeline$.$py

FROM

docker.io$/$library$/$ubuntu
