Hey - I've found 2 issues, and left some high level feedback:
- The
docker-compose.ymlusesDB_HOST/DB_NAME/DB_USER/DB_PASSfor the PHP service andMYSQL_*variables for the DB service, but there’s no visible mapping or defaults; consider aligning these names and adding corresponding entries in.env.example(e.g.DB_HOST=db) so the containers can connect reliably out of the box. - The README instructs running
docker-compose exec php composer install, but thephp:8.1-apacheimage doesn’t include Composer; you likely need to install Composer in the Dockerfile or adjust the docs to use a different image/installation method. - The change in
.github/workflows/release.ymlappears to add a BOM/hidden character beforename: Create Release(note the); it’s better to remove this to avoid subtle tooling or parsing issues.

## Overall Comments
- The `docker-compose.yml` uses `DB_HOST/DB_NAME/DB_USER/DB_PASS` for the PHP service and `MYSQL_*` variables for the DB service, but there’s no visible mapping or defaults; consider aligning these names and adding corresponding entries in `.env.example` (e.g. `DB_HOST=db`) so the containers can connect reliably out of the box.
- The README instructs running `docker-compose exec php composer install`, but the `php:8.1-apache` image doesn’t include Composer; you likely need to install Composer in the Dockerfile or adjust the docs to use a different image/installation method.
- The change in `.github/workflows/release.yml` appears to add a BOM/hidden character before `name: Create Release` (note the ``); it’s better to remove this to avoid subtle tooling or parsing issues.

**issue (bug_risk):** Remove the BOM character before `name` to avoid potential YAML/parsing issues in the workflow file.
There’s a leading BOM/invisible character before `name` (`+name: ...`). Some parsers and tools can mis-handle this and it also leads to noisy diffs. Please remove the BOM so the line is just `name: Create Release`.

**suggestion (performance):** Clean up apt artifacts and consider `--no-install-recommends` to keep the image smaller and more secure.
The current `apt-get` command keeps package lists and installs all recommended packages. To shrink the image and reduce the attack surface, you can use:
```dockerfile
RUN apt-get update \
&& apt-get install -y --no-install-recommends git zip unzip \
&& rm -rf /var/lib/apt/lists/*

The variables DB_USER and DB_PASS reference ${MYSQL_USER} and ${MYSQL_PASSWORD} respectively, which will not be expanded within the .env file itself. Environment variable substitution like this is not standard .env behavior and will likely be interpreted as literal strings rather than the actual values. Either use the literal values directly ("user" and "password"), or ensure your environment loading mechanism supports this substitution pattern.

The default values "your_password" and "your-super-secret-and-long-jwt-key" are insecure placeholders that could be accidentally used in production or committed by developers. Consider using randomly generated default values or adding prominent warnings in comments that these MUST be changed before use.

The Docker Compose version '3.8' is outdated. Current Docker Compose specification recommends omitting the version field entirely for new projects, as it's no longer required and the latest Compose specification is used by default.

There was a problem hiding this comment.
Exposing MySQL port 3306 to the host is unnecessary for typical development workflows where the PHP container connects internally, and creates a potential security risk. Unless external database access is specifically required for debugging, consider removing this port mapping to follow the principle of least exposure.

The Dockerfile installs system packages (git, zip, unzip) but doesn't clean up apt cache afterward, which increases the image size unnecessarily. Add '&& rm -rf /var/lib/apt/lists/*' to the end of the RUN command to reduce the final image size.

A UTF-8 BOM (Byte Order Mark) character has been added at the beginning of the file. This is typically unnecessary for UTF-8 files and can cause issues with some tools and parsers. The BOM should be removed to maintain clean UTF-8 encoding without BOM.

The variable DB_NAME references ${MYSQL_DATABASE} which will not be expanded within the .env file itself. Environment variable substitution like this is not standard .env behavior and will likely be interpreted as the literal string "${MYSQL_DATABASE}" rather than the value "sigortacudb". Either use the literal value "sigortacudb" directly, or ensure your environment loading mechanism supports this substitution pattern.
