Docker driver |
Loki officially supports a Docker plugin that will read logs from Docker containers and ship them to Loki. The plugin can be configured to send the logs to a private Loki instance or Grafana Cloud.
Docker plugins are not yet supported on Windows; see the Docker docs for more information.
Documentation on configuring the Loki Docker Driver can be found on the configuration page.
If you have any questions or issues using the Docker plugin feel free to open an issue in this repository.
The Docker plugin must be installed on each Docker host that will be running containers you want to collect logs from.
Run the following command to install the plugin:
docker plugin install grafana/loki-docker-driver:latest --alias loki --grant-all-permissions
To check installed plugins, use the docker plugin ls
command. Plugins that
have started successfully are listed as enabled:
$ docker plugin ls
ID NAME DESCRIPTION ENABLED
ac720b8fcfdb loki Loki Logging Driver true
Once the plugin is installed it can be configured.
The upgrade process involves disabling the existing plugin, upgrading, then re-enabling and restarting Docker:
docker plugin disable loki
docker plugin upgrade loki grafana/loki-docker-driver:latest
docker plugin enable loki
systemctl restart docker
To cleanly uninstall the plugin, disable and remove it:
docker plugin disable loki
docker plugin rm loki
