Detailed information on the Hazelcast state store component

Create a Dapr component

To setup Hazelcast state store create a component of type state.hazelcast. See this guide on how to create and apply a state store configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: state.hazelcast
  version: v1
  metadata:
  - name: hazelcastServers
    value: <REPLACE-WITH-HOSTS> # Required. A comma delimited string of servers. Example: "hazelcast:3000,hazelcast2:3000"
  - name: hazelcastMap
    value: <REPLACE-WITH-MAP> # Required. Hazelcast map configuration.

Warning

The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.

Setup Hazelcast

• Self-Hosted
• Kubernetes

You can run Hazelcast locally using Docker:

docker run -e JAVA_OPTS="-Dhazelcast.local.publicAddress=127.0.0.1:5701" -p 5701:5701 hazelcast/hazelcast

You can then interact with the server using the 127.0.0.1:5701.

The easiest way to install Hazelcast on Kubernetes is by using the Helm chart.
