PHP_CONFIG_FILE unbound variable with zabbix/zabbix-web-nginx-mysql:ubuntu-latest

[drott]

With a docker compose config, similar to the official instructions for running from docker, with the current zabbix/zabbix-web-nginx-mysql:ubuntu-latest image, the frontend does not start up.
Instead, it reports:

zabbix-web-nginx-mysql-1  | 2026-04-29T08:23:51Z [info]: ** Preparing Zabbix web-interface (Nginx) with MySQL database

I was able to workaround this for now by specifying:
PHP_CONFIG_FILE: /etc/php/8.5/fpm/pool.d/zabbix.conf in the environment settings of nginx web front section of the docker compose file.

Could you try to pull again the image? If problem still exists, please, share sha256 for the pulled image

Issue persists (i.e. does not come up without PHP_CONFIG_FILE workaround) at:

[zabbix/zabbix-web-nginx-mysql@sha256:d309dfebbcf30db21da4ef9f8aa1825813e2aea7c9c31bbf8ac4a38b800e6caa]
