By default there are no Docker does not rotate logs of the containers. This might cause disk space issues when there is something that is intensively logging.
You can set a limit in the /etc/docker/daemon.json
file. Afterwards restart docker
{ "log-driver": "json-file", "log-opts": {"max-size": "10m", "max-file": "3"} } |
It is also possible to set this via the docker compose configuration.
version: '3' services: my_service: logging: driver: "json-file" options: max-size: "5m" |
Running truncate -s 0 /var/lib/docker/containers/*/*-json.log
will clear ALL logs.
