Cannot seem to expose application via Beta images

[magweter]

Hi all,

The serversideup/php:beta-8.2-fpm-nginx image worked perfectly for me! unfortunately just up until a few days ago. Now I cannot seem to get my application to expose through Nginx. I just constantly get a connection refused. When I use the serversideup/php:8.2-fpm-nginx image, my (laravel) application does expose and works like it should. I'm using SSL off and port 8080 (mapped from container port 80) in my browser.

I require the installation of some php-extensions which drives me to use the beta image, as the serversideup/php:8.2-fpm-nginx image does not seem to be able to run install-php-extensions.

I'm really trying to stick to install-php-extensions to escape the apt-get and pecl install hassle.

My dockerfile:

# Set our base image
FROM serversideup/php:beta-8.2-fpm-nginx as base

ENV SSL_MODE=off
ENV PHP_OPCACHE_ENABLE=1

# Switch to root before installing our PHP extensions
USER root

RUN install-php-extensions zlib
RUN install-php-extensions sqlsrv
RUN install-php-extensions pdo_sqlsrv

FROM base as production

COPY --chown=www-data:www-data . .

# Switch back to the unprivileged www-data user
USER www-data

Building succeeds and everything seems ok:

Thanks for the Dockerfile.

I ran a build with your file and it seemed to work just fine:

docker build -t localhost:latest .

Your error

The screenshot you have looks like it's failing on build.

Is this when you're using Docker Compose with a build command?

If so, be sure to add --build --force-recreate to make sure it's not a weird cache:

docker compose up --build --force-recreate

Thanks for your answer. The build for beta works (I only get the error using the non-beta image). The problem was actually suddenly not being able to expose my application through the beta image, which made me try switching to the non-beta image.

I have found the problem. Took me some time though.. I've been looking into the container layers for answers. The image I built a week ago using php:8.2-fpm-nginx as base image has EXPOSE 80,443 as build steps;

Now this seems to have changed, as the most recent image uses EXPOSE 8080,8443;

Thus changing my mapping from 8080:80 to 8080:8080 solved the issue.

I get that the beta image is subject to change. I've been using it as the non-beta 8.2 fpm nginx image does not seem to support install-php-extensions, is that correct? In that case I would love for the image to be released or for the beta image to have versioning to prevent surprises ;-)

The "non-beta" is still "v2".

The "beta" is v3, which is an entire rewrite. I suggest reading this guide: https://serversideup.net/open-source/docker-php/docs/guide/migrating-from-v2-to-v3

If you're starting with a new project, start with the "beta" as that will be released to stable shortly.

If you have an existing project, be sure to lock into v2.2.1 as it's shown in the docs until you have time to refactor with the new v3 images 👍
