This capability, sometimes referred to as dual logging, allows you to use docker logs to read container logs locally in a consistent format, regardless of the remote log driver used, because the Engine is configured to log information to the "local" logging driver. Logfile cohabitation will allow me to incorporate them in the housekeeping rotation ritual of the rest of my system, Brian Burroughs By default, the Docker host machine is configured to write logs to a text file, where each row is a JSON document that includes the time the event occurred and the related log message. driver.docker.version - This will be set to version of the docker server. max-file is here set to "3", so at any point in time there will be only three log files stored. I hope this tutorial has convinced you that using the new Docker GELF drivers is well worth it. To use the local driver as the default logging driver, set the log-driver and log-opt keys to appropriate values in the daemon.json file, which is located in /etc/docker/ on Linux hosts or C:\ProgramData\docker\config\daemon.json on Windows Server. aiordache closed this as completed in #7425 on Aug 3, 2020. wkloucek mentioned this issue on Jan 28, 2021.

By default, the Fluentd logging driver will try to find a local Fluentd instance (step #2) listening for connections on the TCP port 24224, note that the container will not start if it cannot connect to the Fluentd instance. NOTE: Currently, the Fluentd logging driver doesn't support sub-second precision. The Docker Image can run in the role of: Uniface Application Server.

Uniface Web Application Server (excluding the Web Server) Uniface Database Server. In Docker, everything written to stdout and stderr streams is implicitly sent to a logging driver, which provides a mechanism to access these streams and send the logs to a file. The GELF logging driver enables a container to send STDOUT and STDERR messages formatted as GELF messages to a remote, centralized system like Graylog. Clone my ELK repo with: $ git clone git@github.com:MBuffenoir/elk.git $ cd elk. Similar to virtualization, containers add an extra layer between an application and the host OS.
