Wrong error when creating a docker file that is using a base image from an argument #197

Open baruchoxman opened 1 year ago

I have created a docker file that gets the base image name from a variable:

ARG BASE_IMAGE=my-image:base

# Use the base image
FROM $BASE_IMAGE

Issues: 1

Line 4: FROM $BASE_IMAGE
