Summary of Changes

Hello @Ziedelth, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing the security and robustness of the application's Docker deployment. It introduces best practices for container security by configuring the application to run as a non-root user and refines the Playwright browser installation process for better control. Additionally, the Docker Compose healthcheck has been updated to use a more native Node.js-based method for service verification, ensuring more reliable monitoring of the application's health.

Highlights

• Dockerfile Security Enhancements: Introduced a dedicated non-root user (appuser) and group to run the application within the Docker container, significantly improving the security posture by adhering to the principle of least privilege. This includes creating the user, setting appropriate ownership for application directories, and switching to this user before running the main application command.
• Playwright Browser Path Configuration: Explicitly defined and configured the PLAYWRIGHT_BROWSERS_PATH environment variable and created the corresponding directory (/opt/playwright) to manage where Playwright browsers are installed and accessed within the container.
• Docker Compose Healthcheck Update: Replaced the curl-based healthcheck in docker-compose.yml with a more robust node -e script. This change provides a more native and potentially more reliable method for verifying the service's availability and responsiveness within the Node.js-based container environment.

Code Review

This pull request significantly improves the security of the Docker image by introducing a non-root user and removing the curl package. These are excellent changes that follow security best practices. My review includes a few suggestions to further enhance the Dockerfile for better determinism and smaller image size, as well as a recommendation to improve the maintainability of the healthcheck in docker-compose.yml.
