Summary of Changes

Hello @chungyau97, 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 bolstering the security posture of the Docker image by adjusting user permissions within the Dockerfile. It removes the explicit use of the root user during the build process and ensures that the final application execution occurs as the node user, after correctly setting file ownership for the flowise module. This change aligns with best practices for container security, minimizing potential vulnerabilities associated with running processes as root.

Highlights

• Enhanced Security: The Docker image now runs the application as a non-root user (node), significantly improving security by adhering to the principle of least privilege.
• Dockerfile Refinement: Removed an unnecessary USER root declaration from the build stage and explicitly set ownership for the flowise module before switching to the node user for application execution.

Code Review

This pull request improves security by switching the Docker container to run as a non-root node user, which is a commendable change. However, the current implementation has a couple of significant issues. Firstly, the file permission change with chown is too specific and may lead to runtime failures if the application attempts to install global dependencies. Secondly, and more critically, this change will break existing user setups that rely on the provided docker-compose.yml, because the data volume is mounted to a directory that will be inaccessible to the node user. I've provided detailed comments with suggestions to address these points. It's also worth noting that other Dockerfiles in the repository, like docker/worker/Dockerfile, have not been updated to run as a non-root user, leading to inconsistency.
