Dockerfile define multiple ARG arguments in a single line

Question

Right now I am defining ARGs in my Dockerfile like this:

ARG CDN_ENDPOINT
ARG AWS_S3_BUCKET

Is there a way to define them in a single line similar to ENV to avoid creating extra layers in docker image like this:

ENV CDN_ENDPOINT=endpoint \
    AWS_S3_BUCKET=bucket

Answer 1

YES, After release 1.2.0

Previously it was not possible and it threw the following error

ARG requires exactly one argument definition

But after release 1.2.0 it is now possible to define ARG like following

ARG CDN_ENDPOINT \
AWS_S3_BUCKET
