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.

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

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