Deploy Kubernetes operators easily with Juju, the Universal Operator Lifecycle Manager. Need a Kubernetes cluster? Install MicroK8s to create a full CNCF-certified Kubernetes system in under 60 seconds.
Platform:
Tempo-worker charm is configured to work in one of the pre-defined roles. Each tempo-worker application needs to have exactly one role enabled. If a worker application has more than 1 role enabled, it will stop serving requests.
To understand what roles are, see Understanding roles (Managing deployment of COS-Lite HA addons). See Tempo architecture for an explanation of each of the roles.
In order for the Tempo cluster to be functional in a microservice setup, multiple worker applications should be deployed and configured with the required roles. If a required role is missing, the cluster will be seen as inconsistent and will cease to work.
