Deploying frankenphp on render.com

Help

1. The problem I’m having:

Hi there,

I’m trying to get a pretty standard Laravel app deployed on a Render web service instance with FrankenPHP.

Here’s my Dockerfile:

FROM dunglas/frankenphp 
RUN install-php-extensions \
 pdo \
 gd \
 intl \
 zip \
 opcache

RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer
COPY . /app
RUN composer install --no-interaction --no-scripts --no-suggest
RUN php artisan config:cache
RUN php artisan route:cache
RUN php artisan migrate --force

# Line below needed otherwise build exits with a permissions error
RUN setcap -r /usr/local/bin/frankenphp

Locally, if I run (from the docs):

docker run -p 80:80 -p 443:443 -p 443:443/udp -v $PWD:/app dunglas/frankenphp

Everything works as expected.

On Render, when I deploy everything seems to build and start correctly, I even get the default Laravel uptime endpoint (/up) returning something positive as the healthcheck passes, however if I try to visit the site in a browser I get the “TOO MANY REDIRECTS” error.

I’ve tried clearing my cookies, different browsers and tweaking the ports exposed but nothing seems to help. I don’t really have anything special set up in the environment as shown below:

I think the issue might be something to do with the default port binding and/or proxying from HTTPS → HTTP but I don’t know enough about this to get it working.

Any ideas welcomed! Thanks in advance

That screenshot link doesn’t work.

What do you mean? You must have a Caddyfile?

What do you mean? You must have logs. Caddy always emits logs to stdout.

Thanks for responding, I’ve updated the original post with hopefully everything that was missing.

The screenshot up here still doesn’t work. Is it behind your private github account or something?

I still don’t see any evidence of a problem. Show a request with curl -v.

From your Caddy logs, it looks like Caddy issued a cert for localhost, meaning it’s listening for HTTPS with the hostname localhost. You probably mean to set the SERVER_NAME env var to change that to your actual domain.

I don’t know how <render.com> works.
