Pull request overview
This pull request adds Docker deployment support to the MS_OAuth2API_Next project, making MySQL database usage optional instead of required. The key changes enable the application to run in Docker containers with flexible database configuration.
Key Changes:
- Makes MySQL database optional with conditional initialization based on environment variables
- Adds complete Docker deployment setup with docker-compose for app, Redis, and optional MySQL services
- Updates database connection logic to handle scenarios where MySQL is not configured
- Adds comprehensive Docker deployment documentation

This method directly uses pool.query() without checking if pool is null. Since the database is now optional, this should use this.query() instead to ensure consistent error handling when the database is not configured.

The port value should be converted to an integer. Currently, if DB_PORT is provided as a string environment variable, it will be passed as a string to mysql.createPool(). Use parseInt(process.env.DB_PORT) || 3306 to ensure proper type conversion.
| port: process.env.DB_PORT || 3306, | |
| port: parseInt(process.env.DB_PORT) || 3306, |

The DB_QUEUE_LIMIT environment variable is commented out in the Docker configuration but is still referenced in the db.js file with a fallback value. Consider adding this environment variable to the commented MySQL configuration section for completeness and consistency.

| #- DB_CONNECTION_LIMIT=10 | |

The comment "skip type-check for faster builds" is misleading because npm run build-only is a standard Next.js/Vite command that naturally skips type checking (unlike npm run build). Consider removing or clarifying this comment to avoid confusion.
| # Build frontend (skip type-check for faster builds) | |
| # Build frontend using the build-only script |

This container runs node main.js as the root user because no non-root user is configured in this Dockerfile. If an attacker ever gains code execution in the Node process (for example via a framework or dependency vulnerability), they will have root privileges inside the container, which increases the risk of container escape and damage to any mounted volumes. Create and switch to a dedicated unprivileged user via USER before starting the app to limit the blast radius of a compromise.
