Unable to Activate Persistent Ignite Cluster

Question

We are trying to use control.sh to activate out Ignite cluster which is running in Kubernetes and has native persistence as described here , however we are getting to error below.

We have also tried activating the cluster via the post install of the auto deployment but are getting the same error.

lifecycle:
    postStart:
        exec:
            command:
              - >-
                /opt/ignite/apache-ignite/bin/control.sh --set-state ACTIVE
                 --yes

Error:

/opt/ignite/apache-ignite/bin/control.sh --set-state ACTIVE
failed - error: command '/bin/sh -c /opt/ignite/apache-ignite/bin/control.sh --set-state ACTIVE' exited with 2: , message: "JVM_OPTS environment variable is set, but will not be used. To pass JVM options use CONTROL_JVM_OPTS

Activating the cluster relates to the lifecycle of the cluster rather than an individual pod, do you don't want to add it to the pod.

Instead, it's a "manual" process once all your nodes/pods are up. I wrote about it here .

In short, either run exec:

kubectl exec -it ignite-0 --namespace=ignite -- /opt/ignite/apache-ignite-fabric/bin/control.sh --activate

Or create a Kubernetes job.
