You can ignore this lecture if you’re not facing errors in the next lecture. However, if you do, take another look at this text lecture here.

When using Docker on Linux, you might face permission errors when adding a bind mount as shown in the next lecture. If you do, try these steps:

Change the php.dockerfile so that it looks like that:

FROM php:8.0-fpm-alpine

WORKDIR /var/www/html

COPY src .

RUN docker-php-ext-install pdo pdo_mysql

RUN addgroup -g 1000 laravel && adduser -G laravel -g laravel -s /bin/sh -D laravel

USER laravel

Please note that the RUN chown instruction was removed here, instead we now create a user “laravel” which we use (with the USER instruction) for commands executed inside of this image / container).

Also edit the composer.dockerfile to look like this:

FROM composer:latest

RUN addgroup -g 1000 laravel && adduser -G laravel -g laravel -s /bin/sh -D laravel

USER laravel

WORKDIR /var/www/html

ENTRYPOINT [ "composer", "--ignore-platform-reqs" ]

Here, we add that same “laravel” user and use it for creating the project therefore.

These steps should ensure that all files which are created by the Composer container are assigned to a user named “laravel” which exists in all containers which have to work on the files.
