Introduction

Kiali uses Jaeger as a default distributed tracing backend. In this tutorial, we will replace it for Grafana Tempo.

We will setup a local environment in minikube, and install Kiali with Tempo as a distributed backend. This is a simplified architecture diagram:

We will install Tempo with the Tempo Operator and enable Jaeger query frontend to be compatible with Kiali in order to query traces.
We will setup Istio to send traces to the Tempo collector using the zipkin protocol. It is enabled by default from version 3.0 or higher of the Tempo Operator.
We will install MinIO and setup it up as object store, S3 compatible.

Environment

We use the following environment:

Steps to install Kiali and Grafana Tempo

We will start minikube:

minikube start

It is a requirement to have cert-manager installed:

kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.12.0/cert-manager.yaml

Install the operator. It is important to download a version 3.0 or higher. In previous versions, the zipkin collector was not exposed, there was no way to change it as it was not defined in the CRD.

kubectl apply -f https://github.com/grafana/tempo-operator/releases/download/v0.3.0/tempo-operator.yaml

We will create the tempo namespace:

kubectl create namespace tempo

We will deploy minio, this is a sample minio.yaml:
