Im trying to follow the documentation for using the docker image - need help

Hello,

I am looking at the documentation for Installation - Docker PHP - Server Side Up

however, I am having troubles.
I’d like to use the nginx-fpm php image, but upon looking at the Dockerfile,
I am unsure what to put for UPSTREAM_CHANNEL variable

ARG UPSTREAM_CHANNEL=''
ARG PHP_VERSION='8.1'
ARG BASE_IMAGE="serversideup/php:${UPSTREAM_CHANNEL}${PHP_VERSION}-fpm"

FROM ${BASE_IMAGE}

Is there any tutorial available for using these images?

Those are build arguments mainly for my use. You don’t need to worry about setting an up stream channel.

The only documentation I have are the ones published online and this YouTube video: https://www.youtube.com/watch?v=PInGAWnvkjM

I am currently working on v3 of these images, then I will be focusing on creating more content afterwards.

Hope this helps!
