Description of the change

This change provides a new way of deployment: scaling-monolithic.

If toggle .Values.tempo.deploymentMode, which is "microservices" by default, is set as "scalingMonolithic", single statefulset will be created. Each pod conatins all functions of components: distributor, ingester, query-frontend, querier, metrics-generator and compactor.

Benefits

It helps to maintain a reasonable size of cluster handling small to medium volumes of incoming traces.

Hi @jotamartos @migruiz4 , I've tested my changes with minikube locally. New statefulset works fine as a cluster.

Regarding the VIB test, how to achieve 2 different sets of env for testing?

Since it should test both cases:

  • tempo.deploymentMode=microservices
  • tempo.deploymentMode=scalingMonolithic
