Permissions Issue After docker compose up --wait on Ubuntu (root-owned files causing Git + Composer errors)

[clevercodenl]

After running docker compose up --wait

several files and directories inside the project (including /app inside the php container) are created as root, not as my local user.
This leads to multiple problems:

1. Git refuses to operate inside /app

The php container reports:

fatal: detected dubious ownership in repository at '/app'
To add an exception for this directory, call:

        git config --global --add safe.directory /app

2. Composer fails to install dependencies

Composer is unable to resolve multiple dependencies due to missing Symfony packages that are not loaded correctly (likely caused by Git + permission issues):

Problem 1
    - Root composer.json requires runtime/frankenphp-symfony * -> satisfiable by runtime/frankenphp-symfony[0.1.0, 0.1.1, 0.2.0].
    - runtime/frankenphp-symfony[0.1.0, ..., 0.1.1] require symfony/dependency-injection ^5.4 || ^6.0 -> found symfony/dependency-injection[v5.4.0, ..., v5.4.48, v6.0.0, ..., v6.4.26] but these were not loaded, likely because it conflicts with another require.
    - runtime/frankenphp-symfony 0.2.0 requires symfony/dependency-injection ^5.4 || ^6.0 || ^7.0 -> found symfony/dependency-injection[v5.4.0, ..., v5.4.48, v6.0.0, ..., v6.4.26, v7.0.0, ..., v7.4.0] but these were not loaded, likely because it conflicts with another require.

3. .env file cannot be found

grep: .env: No such file or directory

4. Cannot open bin/console

Could not open input file: bin/console

Below you can see a screenshot of the docker container logs and the directory in host:

Expected Behavior

Files created during docker compose up --wait should be owned by the same user as the one running the command, or by UID/GID that matches the configured PHP container user (default: 1000:1000).

Git should not reject the repository due to ownership issues.

Composer should be able to install all dependencies successfully.

Hi @clevercodenl!

several files and directories inside the project (including /app inside the php container) are created as root, not as my local user.
<…>
Files created during docker compose up --wait should be owned by the same user as the one running the command, or by UID/GID that matches the configured PHP container user (default: 1000:1000).

This is normal behavior for this repository. The container runs as root. All actions within the container (creating files, editing them, and running them) occur as root. There is a separate issue in this repository discussing the issue of running a container as an unprivileged user, see #679.

This is an error from Git. Typically, it's just an annoing informational message that doesn't affect Composer. See #744.

2. Composer fails to install dependencies
3. .env file cannot be found
4. Cannot open bin/console

I'm guessing this might be related to using the latest version of Symfony v8.0, when the runtime/frankenphp-symfony package is no longer needed as of Symfony v7.4. The runtime/frankenphp-symfony package hasn't been updated to support Symfony v8.0, and I'm guessing this is causing the error.

You can try repeat the change from #873 to fix the dependency error. After making this change will you need to rebuild the image and container with the following command:

docker compose up --wait --build
