Motivations for Restructure💣
The original Loki BigBang chart referenced Grafana’s Loki monolith chart as its upstream source. It was restructured to support two main goals.
- Support Loki’s multiple architectures with a consistent interface for chart consumers
- Support Grafana Enterprise Logs, Grafana’s enterprise functionality as an optional additional component
Migrating from 2.x.x💣
Previous values passed into values.yaml should be nested under loki: which should remain consistent with the previous top level values.
The main caveat to that is the previous implementation included .Values.config.existingSecret which allowed you to use a specified secret for a config. This value has been replaced with .Values.global.existingSecretForConfig which behaves the same way but was relocated to provide an option that was consistent for all architecture modes.

Using Simple Scalable Architecture💣
To opt for the simple scalable architecture enable loki-simple-scalable and disable loki
See Configuration for options building the Loki config for the simple-scalable architecture
loki-simple-scalable:
enabled: true
loki:
enabled: false
Loki Config Options💣
To specify a config file for Loki you can either:
- Leverage the respective
configobject in either thelokiandloki-simple-scalablesubchart depending on which architecture you choose. - Specify a secret to use with
global.existingSecretForConfig - Use the secret generated in the parent chart, by setting
.Values.global.createGlobalConfig: trueand.Values.global.existingSecretForConfig: loki-config
Loki💣
.Values.loki.config
Loki Simple Scalable💣
.Values.loki-simple-scalable.loki.config
Existing Secret💣
.Values.global.existingSecretForConfig
Refactored Structure (3.x.x)💣
The updated design includes the additional upstream of simple-scalable chart, as well as components from the enterprise logs chart.
The previous chart implementation (Loki 2.x.x-bb.x), referenced the loki monolith chart exclusively as its upstream.
