Docker entrypoint error

[hiker]

Hi

Tried to install GnuSocial V3 on a fresh Ubuntu 22.04 server. I tried 
the "Docker" version.

I did the setup with the configure script - full docker support.

But when I run it with "docker-compose up" I am getting errors:

worker_1   | exec /usr/local/bin/docker-php-entrypoint: exec format error
php_1      | exec /usr/local/bin/docker-php-entrypoint: exec format error

nginx/1.23.0 seems to work - browser is getting a 502 - Bad Gataway, the 
Letsencrypt certificate seems to be installed correctly.

Where to search for the problem?
