Unit: The module to run "php" is not found among the available application modules

[donferi]

I've been using the image 8.2 for a while and I'm trying to move to unit-8.2, however I'm getting an invalid configuration error.

I'm not doing anything interesting on my Dockerfile, but just in case, here it is:

I've modified the entrypoint to:

#!/usr/bin/env sh

# Run user scripts, if they exist
for f in /var/www/html/.fly/scripts/*.sh; do
    # Bail out this loop if any script exits with non-zero status code
    bash "$f" -e
done
chown -R www-data:www-data /var/www/html

if [ $# -gt 0 ]; then
    # If we passed a command, run it as root
    exec "$@"
else
    # exec supervisord -c /etc/supervisor/supervisord.conf
    exec unitd --no-daemon --log /dev/stdout
fi

I'm quite sure this is a user error, but I can't figure it out, would love some guidance.

IIRC if you’re using nginx unit, this is likely due to Unit releasing a new version of Unit, which this repo hasn’t incorporated.

We never supported unit officially (it was added as an experiment), so the repo hasn’t kept up with new Unit versions.

However PRs are welcome for that.

[fideloper]

it’s probably just updating this like to the latest version https://github.com/fly-apps/laravel-docker/blob/main/src/Dockerfile-unit#L4

Which I think is 1.32.1 (based on this repo https://github.com/nginx/unit ).

It’s a bit hard to see because I’m on my phone and github’s interface hides releases (?!) on mobile.

Thanks for the replay @fideloper I tried for a bit but when back to php-fpm. Closing the issue as this is an experiment.
