Description
The MAINTAINER instruction sets the Author field of the generated images.
MAINTAINER is deprecated since Docker 1.13.0.
In case you need similar functionality consider using a LABEL.
The LABEL instruction is a much more flexible version of MAINTAINER,
as it enables setting any metadata you require, and can be viewed easily,
for example with docker inspect.
Bad Practice
FROM debian:buster
MAINTAINER John Doe <[email protected]>
Recommended
FROM debian:buster
LABEL org.opencontainers.image.authors="[email protected]"
This will then be visible from docker inspect with the other labels.
