Can you differentiate between Daemon Logging and Container Logging?

Answer»
  • In DOCKER, logging is supported at 2 levels and they are logging at the Daemon level or logging at the Container level.
  • Daemon Level: This KIND of logging has four levels- Debug, Info, Error, and Fatal.
    - Debug has all the data that happened during the execution of the daemon process.
    - Info carries all the information along with the error information during the execution of the daemon process.
    - Errors have those errors that occurred during the execution of the daemon process.
    - Fatal has the fatal errors that occurred during the execution.
  • Container Level:
    - Container level logging can be done using the command: SUDO docker run –it <container_name> /bin/bash
    - In ORDER to check for the container level logs, we can run the command: sudo docker logs <container_id>
