Spec metadata fields

Field	Required	Details	Example
connectionString	Y	A comma delimited string of servers. Example: “hazelcast:3000,hazelcast2:3000”	`“hazelcast:3000,hazelcast2:3000”`

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.
