Logging improvements
Goal
Sometimes we didn't see any Postgres containers running. It's quite difficult to clarify and know what happened. Therefore, we have to centralize and improve the logging system
TODO / How to implement
- Use centralized log(zap) and inject it through the app. Examples:
- remove a custom log package
- remove meaningless and clogging log entries
- check and add(if necessary) log entries for container management operations
Acceptance criteria
We understand what happened inside the Database Lab because we have a clear, extensible and useful logging system.
