Quickstart

Hazelcast Platform Enterprise requires a license key. If you don’t have a license key, you can request one at the Hazelcast website.

helm repo add hazelcast https://hazelcast-charts.s3.amazonaws.com/
helm repo update
helm install my-release hazelcast/hazelcast-enterprise --set hazelcast.licenseKey=<license_key>

For users who already added hazelcast repo to their local helm client before; you need to run helm repo add command again to use latest charts at the new chart repo.

helm repo list

NAME            URL
hazelcast       https://hazelcast.github.io/charts/
...

helm repo add hazelcast https://hazelcast-charts.s3.amazonaws.com/

NAME            URL
hazelcast       https://hazelcast-charts.s3.amazonaws.com/

Installing the Chart

To install the chart with the release name my-release:

helm install my-release hazelcast/hazelcast-enterprise --set hazelcast.licenseKey=<license_key>

The command deploys Hazelcast on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

List all releases using helm list command.

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm uninstall my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the --set key=value,key=value argument to helm install. For example,

helm install my-release hazelcast/hazelcast \
    --set hazelcast.licenseKey=<license_key>,cluster.memberCount=3

The above command sets number of Hazelcast members to 3.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

helm install my-release hazelcast/hazelcast -f values.yaml

You can use the default values.yaml with the hazelcast.license filled in.

Some of the Hazelcast Enterprise features requires setting securityContext.readOnlyRootFilesystem parameter to false. This is the case for the Hot Restart feature or enabling security with OpenSSL. In such cases where readOnlyRootFilesystem needs to be set to true (i.e. a Pod Security Policy requirement), for Hot Restart to work the JVM parameter -Djava.io.tmpdir should be set to a writable location (for example a custom volume).

Notable changes

2.8.0

Hazelcast REST Endpoints are no longer enabled by default and the parameter hazelcast.rest is no longer available. If you want to enable REST, please add the related endpoint-groups to the Hazelcast Configuration. For example:

rest-api:
  enabled: true
  endpoint-groups:
    HEALTH_CHECK:
      enabled: true
    CLUSTER_READ:
      enabled: true
    CLUSTER_WRITE:
      enabled: true

5.8.0

The parameter hotRestart has been renamed to persistence. To use the persistence feature make sure that your values.yaml is updated. For example:

persistence:
  enabled: true
  base-dir: /data/persistence
  validation-timeout-seconds: 1200
  data-load-timeout-seconds: 900
  auto-remove-stale-data: true
