Logging

Docker logs​

Logs from FerretDB running on Docker can be accessed through the container.

If Docker was launched with our quick local setup with Docker Compose, the following command can be used to fetch the logs.

docker compose logs ferretdb

Otherwise, you can check a list of running Docker containers with docker ps and get logs with docker logs:

$ docker ps
CONTAINER ID   IMAGE                       COMMAND                  CREATED              STATUS          PORTS                                           NAMES
13db4c8800d3   postgres                    "docker-entrypoint.s…"   About a minute ago   Up 59 seconds   5432/tcp                                        my-postgres

$ docker logs my-ferretdb

Binary executable logs​

FerretDB writes logs to the standard error (stderr) stream but does not retain them. Refer to the flags to adjust the log level.
