Feature Request: It would be great if the docker image contained a label with the version number

[pheitman]

Prerequisites

• I am running the latest code. Mention the version if possible as well.
• I carefully followed the README.md.
• I searched using keywords relevant to my issue to make sure that I am creating a new issue that is not already open (or closed).
• I reviewed the Discussions, and have a new and useful enhancement to share.

Feature Description

When checking the current container I haven't been able to determine which version I'm running. It would be great if the procedure for building the docker images included these two labels

ARG BUILD_DATE
ARG APP_VERSION

LABEL org.opencontainers.image.created=$BUILD_DATE
LABEL org.opencontainers.image.version=$APP_VERSION

Motivation

That way I'd know how far behind I am from the most recent and I can better evaluate if I should pull a newer image.

Possible Implementation

The docker build command would need to be updated to include

docker build --build-arg BUILD_DATE=$(shell date +"%Y-%m-%dT%H:%M:%S%Z") --build-arg APP_VERSION=${APP_VERSION}
