Setup a Hazelcast state store
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
The easiest way to install Hazelcast on Kubernetes is by using the Helm chart.
Create a Dapr component
The next step is to create a Dapr component for Hazelcast.
Create the following YAML file named
apiVersion: dapr.io/v1alpha1 kind: Component metadata: name: <NAME> namespace: <NAMESPACE> spec: type: state.hazelcast 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.
WarningThe above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.
Apply the configuration
To apply the Hazelcast state store to Kubernetes, use the
kubectl apply -f hazelcast.yaml
To run locally, create a
components dir containing the YAML file and provide the path to the
dapr run command with the flag
