Description

wget without flag --progress will result in excessively bloated build logs when downloading larger files because it outputs a line for each fraction of a percentage point.

​
Examples

​
Problematic code

FROM ubuntu:20
RUN wget https://example.com/big_file.tar

​
Correct code

FROM ubuntu:20
RUN wget --progress=dot:giga https://example.com/big_file.tar
or: 
FROM ubuntu:20
RUN wget -nv https://example.com/big_file.tar

​
Auto-fix

Adds --progress=dot:giga to wget commands. Skipped if -q, --quiet, -nv, --no-verbose, -o, --output-file, -a, --append-output, or --progress is already present. 
# Before
RUN wget http://example.com/file.tar.gz

# After (with --fix)
RUN wget --progress=dot:giga http://example.com/file.tar.gz
