Dockerfile build doesn't get PORT arg (railway CLI)

Here's the Dockerfile. It works perfectly on my local machine:

FROM php:8.2-apache

ARG PORT
ENV PORT=$PORT

COPY ./src/ /var/www/html/

# Change the port numbers in apache's config files...

# Comment out all ports that are not in an IfModule block
RUN sed -i '/<IfModule/,/<\/IfModule>/! s/^\(Listen [0-9]*\)/# Disabled in image build step:\n# \1/' /etc/apache2/ports.conf
# Add correct port to end of file
RUN echo "Listen ${PORT}" >> /etc/apache2/ports.conf

# Output file contents for debugging
RUN cat /etc/apache2/ports.conf

# Duplicate the first occurrence of a VirtualHost opening tag and comment out the duplicate
RUN sed -i '/<VirtualHost/{p;h;s/^/# Disabled in image build step:\n# /g}' /etc/apache2/sites-available/000-default.conf
# Change the original with the correct port
RUN sed -E -i "0,/VirtualHost \*:[0-9]+/s//VirtualHost *:${PORT}/" /etc/apache2/sites-available/000-default.conf

# Output file contents for debugging
RUN cat /etc/apache2/sites-available/000-default.conf

RUN echo PORT value: $PORT
CMD echo PORT value: $PORT

EXPOSE $PORT

EXPOSE $PORT

ok, in a different service (ID: 108e166f-6409-417f-ab3a-fbf9884561f0), I tried setting PORT=8080 in my service variables and the port was accessible in both build and deployment, so my app should be listening on 8080, but I'm getting 503, "Application failed to respond" when I visit the public URL (https://grandiose-friction-production.up.railway.app/)
