build docker image with label $BUILD_DATE

Alen Cappelletti 992

Hi,

I'm using visual studio 2022 with a simple Dockerfile on windows.

I build a image with success but 2 label are not valued correctly, with this line from

Developer Powershell:
docker build --no-cache --build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') -t test .

Do I have to create an ARG and value it in the docker file? Or can I do in the command line... like above?
This $BUILD_VERSION is something related to VS?
How do I value it?

Thanks Alen

LABEL org.label-schema.build-date=$BUILD_DATE
LABEL org.label-schema.version=$BUILD_VERSION

I get it... I had to enter the ARGs...
and

docker build --no-cache --build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') -build-arg BUILD_VERSION=1.0.0 -t test .

but... what if I want to make the build number dynamic?

I build the image from "Powershell Developer" not from VS play button...

I know that there is a variable that is set to value at each number of BUILDs.
Thank you

# Labels ARG BUILD_DATE ARG BUILD_VERSION LABEL org.label-schema.schema-version="1.0" LABEL org.label-schema.build-date=${BUILD_DATE} LABEL org.label-schema.version=${BUILD_VERSION:-1.0}
