I think I found a solution in your permission issues

[torian257x]

great series

problem with permissions is imho this:

permissions work with user id and not name
at least on my ubuntu system

my main user in my host system has user id 1001

echo $(id -u) # 1001 lets call this user myuser

it's because the system came with a user already installed, and I created my own user

the "first installed" user, get 1000, lets call it wronguser

I am speculating a bit here but
when you do

ls -l

you get, say

drwxr-xr-x   42 myuser myuser       4096 Aug  4 10:07 vendor

in reality in my case, what is there is actually (ive seen it)

drwxr-xr-x   42 1001 1001       4096 Aug  4 10:07 vendor

so your line in the dockerfile

RUN adduser -g ${PHPGROUP} -s /bin/sh -D ${PHPUSER}

doesn't do anything useful afaik.

because whatever user you add, and then define in config file, will have user id 1000

and then my host system will get in the mounted volume all files with permissions for user id 1000 for user: wronguser

system goes poof cause everything has wrong permissions now

solution 1 is, I guess, to change the user id of wronguser to something else, and myuser to 1000

I didnt feel comfortable doing that though, i dont know usermod that wall.

A workaround for me was to put

RUN apk add shadow && usermod -u 1001 myuser && groupmod -g 1001 myuser

into the php.dockerfile

e.g. complete php.dockerfile

FROM php:8-fpm-alpine

ENV PHPGROUP=myuser
ENV PHPUSER=myuser



RUN adduser -g ${PHPGROUP} -s /bin/sh -D ${PHPUSER}

RUN sed -i "s/user = www-data/user = ${PHPUSER}/g" /usr/local/etc/php-fpm.d/www.conf
RUN sed -i "s/group = www-data/group = ${PHPGROUP}/g" /usr/local/etc/php-fpm.d/www.conf

RUN apk add shadow && usermod -u 1001 myuser && groupmod -g 1001 myuser

RUN mkdir -p /var/www/html/public


RUN docker-php-ext-install pdo pdo_mysql

CMD ["php-fpm", "-y", "/usr/local/etc/php-fpm.conf", "-R"]

that way all the log and session files will have the right user and permission

I use in the docker compose file as well

  php:
    build:
      context: .
      dockerfile: php.dockerfile
    user: myuser
    volumes:
      - ./src:/var/www/html
