spring-boot-debug-app VS helm-charts

This is a GitHub link to my demo app. It’s simple Spring Boot web app used to debugging various stuff. There are many ways to configure JSON logging in Spring Boot. I decided to use Logback because it is easy to configure and one of the most widely used logging library in the Java Community. To enable JSON logging we need to add below dependencies.

My demo app (GitHub Link) uses Spring Boot version 3, or more precisely the latest release from 2022, i.e. 3.0.1. The core monitoring component in Spring Boot is Actuator. If you remember the migration of Spring Boot from version 1 to 2, you’ll probably remember that update brought a lot of breaking changes in Actuator. Fortunately, in the case of version 3, no such changes have been made, so you can apply the following configurations to Spring Boot version 2.x.x

Which helm Chart do you use? You should probably use this one https://github.com/grafana/helm-charts/tree/main/charts/loki-distributed

We were able to keep this config in Grafana UI but if the pod (K8S) is fail the details is deleted, we are using latest prom helm .

Grafana Labs in its Helm repository provides chart that can install Loki stack also with other complementary tools like Logstash or Prometheus.

Once you have this ready for your cluster install Grafana from Grafana helm chart from here

grafana/helm-charts/blob/main/charts/loki-stack/Chart.yaml

Using the helm chart values from values.yaml here https://github.com/grafana/helm-charts/blob/main/charts/grafana/values.yaml

Hey everyone! This is probably an easy question for those of you with experience. I’m using helm to install loki-stack and cannot figure out how to enable the query frontend with the Helm chart.
