   • pgAdmin: http://localhost:5050
   • Dozzle: http://localhost:9999

• Postgres DB Logging Issue:

  • The PostgreSQL database logs an error: "role 'root' does not exist". The database works regardless, but this issue needs to be resolved.

• Vector Log Shipping:

  • Shipping logs using Vector still needs a bit of work to ensure all logs are correctly shipped to BetterStack.

• Postgres Startup Packet Error:

  • PostgreSQL logs an error: "invalid length of startup packet". This is related to connections to the database, but only the Django service is currently connected.

• MongoDB Express Connection Issue:

  • MongoDB Express tries to connect to MongoDB before MongoDB is fully operational, even with the depends_on attribute.

• Grafana Configuration:

  • Grafana setup and configuration need further attention to ensure it works correctly with the provided datasources.

• Ensure that Docker and Docker Compose are installed on your system.
• Adjust the environment variables in the .env file to match your setup.
• The docker-compose.prod.yml file is configured for production use. For development, use the docker-compose.yml file.
• Feel free to explore each service in detail. Happy coding!
