Dapr Placement control plane service overview

Overview of the Dapr placement service

The Dapr Placement service is used to calculate and distribute distributed hash tables for the location of Dapr actors running in self-hosted mode or on Kubernetes. This hash table maps actor IDs to pods or processes so a Dapr application can communicate with the actor.Anytime a Dapr application activates a Dapr actor, the placement updates the hash tables with the latest actor locations.

Self-hosted mode

The placement service Docker container is started automatically as part of dapr init. It can also be run manually as a process if you are running in slim-init mode.

Kubernetes mode

The placement service is deployed as part of dapr init -k, or via the Dapr Helm charts. For more information on running Dapr on Kubernetes, visit the Kubernetes hosting page.
