Based on the nginx + php-fpm image from TrafeX and the official phpMyAdmin image, this Docker image is an alternative to the official php-fpm one, since it's not really usable.
docker run -p '8080:8080' -e PMA_HOST=dbhost ghcr.io/colibris-xyz/phpmyadmin:latest
All environment variables exposed in the official image are available, with just one addition :
PMA_BLOWFISH_SECRET- define the blowfish secret
