grafloki start

To start a Grafana/Loki instance in Docker or K8s cluster, run:

kurtosis grafloki start

This command starts a local Grafana/Loki instance and restarts the Kurtosis engine with an updated configuration. The new configuration includes a log sink that routes logs to the local Grafana/Loki instance.

If you only need the Loki sink and do not want Grafana provisioned, use loki start instead.

Read more about sinks and how to export logs from Kurtosis.

Kurtosis Config allows configuring grafana-loki and should-enable-default-logs-sink configurations.
