--allow-to-run-as-root stopped working in shinsenter/php:8.2-fpm

[stefanpejcic]

noticed that on a fresh server, image shinsenter/php:8.2-fpm no longer accepts root:root and fails to start:

[04-Aug-2025 12:19:17] ERROR: [pool www] please specify user and group other than root
[04-Aug-2025 12:19:17] ERROR: FPM initialization failed

even with the --allow-to-run-as-root flag:

  php-fpm-8.2:
    image: shinsenter/php:8.2-fpm
    restart: unless-stopped
    environment:
      - APP_USER=root
      - APP_GROUP=root
      - APP_UID=${USER_ID:-0}
      - APP_GID=${USER_ID:-0}
      - ENABLE_TUNING_FPM=1
    command: >
      sh -c "php-fpm --allow-to-run-as-root"

---

For an older version of the same tag (image from 2025-05-07), this is still working:

php-fpm-8.2  | UID / GID     : root:root (0:0)
php-fpm-8.2  | App Root      : /var/www/html

Has anything changed in the syntax or is the flag removed?

[shinsenter]

@stefanpejcic

I've tried pulling the Docker image you mentioned (latest build), but unfortunately, I couldn't reproduce the issue you're facing.

Could you provide more details—like whether there are any custom configurations (e.g., the value of $USER_ID)?

[shinsenter]

@stefanpejcic BTW, could you try again by removing the command section in your docker-compose.yml?

services:
  php-fpm-8.2:
      image: shinsenter/php:8.2-fpm
      restart: unless-stopped
      environment:
        - APP_USER=root
        - APP_GROUP=root
        - APP_UID=${USER_ID:-0}
        - APP_GID=${USER_ID:-0}
        - ENABLE_TUNING_FPM=1

Or just try running php-fpm directly using command (no need to call it through sh).

services:
  php-fpm-8.2:
      image: shinsenter/php:8.2-fpm
      restart: unless-stopped
      environment:
        - APP_USER=root
        - APP_GROUP=root
        - APP_UID=${USER_ID:-0}
        - APP_GID=${USER_ID:-0}
        - ENABLE_TUNING_FPM=1
      command: php-fpm

[shinsenter]

The Alpine version also doesn't seem to have any issues.

[stefanpejcic]

thanks, only when using sh in command it errors, without command and with just php-fpm its working.

without command section:
