Hazelcast
Detailed documentation on the Hazelcast pubsub component
Setup Hazelcast
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.
Create a Dapr component
The next step is to create a Dapr component for Hazelcast.
Create the following YAML file named hazelcast.yaml
:
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
name: <NAME>
namespace: <NAMESPACE>
spec:
type: pubsub.hazelcast
version: v1
metadata:
- name: hazelcastServers
value: <REPLACE-WITH-HOSTS> # Required. A comma delimited string of servers. Example: "hazelcast:3000,hazelcast2:3000"
Warning
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.
Apply the configuration
