Noob question about ARG variable

Image Builds

I have an issue with this dockerfile:

FROM nvidia/cuda:12.4.0-base-ubuntu22.04

# Allow passing in your host UID/GID (defaults 1000:1000)
ARG UID=1000
ARG GID=1000
#webgui service port
ARG PORT=8018

--- SNIP ---

# Expose the port that ComfyUI will use (change if needed)
EXPOSE $PORT

ENTRYPOINT ["/entrypoint.sh"]
CMD ["python","/app/ComfyUI/main.py","--listen","0.0.0.0","--port", ${PORT}]

In the last line the argument port isn’t valorized and the command fail…

Anyone with any tips ?

Did you use a long dockerfile having several FROM clause (i.e. a multi-stages Docker file). If so, you’ve to add ARG PORT again (but without the need to assign a default value), this after your FROM clause, before to use the variable.

uhm not really the source is this:

i’ll try you tweak anyway…

ARG with default values should be defined before the first FROM. In your file, it’s after. Please try to move the FROM line after
