Program crashes when show container log

[Ringeltier]

Hello everyone.
When a container is started with another log driver eg. fluentd the container will not have a json log. In this case the dry program will crash because it can not open a file which not exists.

You have to implement a check for the log driver of each container to prevent this case.

Sincerely,
Stefan

Thanks for reporting!

If you try to fetch logs in a container without logs (runned with logging driver="none"), Container is freezed.

@bypper I have not been able to reproduce it. I tried fetching the logs of a container run with log-driver none (docker run -it --log-driver none alpine ash) and dry shows an error.

Hi @moncho,
This is my command:

docker compose -f 0-compose-global.yml run --name midry --rm dry; docker image rm moncho/dry

and this is the compose block related:

  dry:
    container_name: midry
    image: moncho/dry
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      TZ: Europe/Madrid
    networks:
      - albred
      - albredpriv
    deploy:
      resources:
        limits:
          cpus: '0.3'
    # Disable logging for this service...
    logging:
      driver: "none"

Actually, container is not freeze, I can see is up, but the foreground screen yes, and I cannot work with it already, after select "Fetch logs" option of menu.
