I have an ignite cluster and I try to add a control center of gridgain according to their documentation: https://www.gridgain.com/docs/control-center/latest/installation/kubernetes(see deployment.yaml below) but I keep getting this error
$ kubectl apply -f control-center-backend-deployment.yaml
error: error validating "control-center-backend-deployment.yaml": error validating data: [ValidationError(Deployment.spec): unknown field "serviceName" in io.k8s.api.apps.v1.DeploymentSpec, ValidationError(Deployment.spec): unknown field "volumeClaimTemplates" in io.k8s.api.apps.v1.DeploymentSpec]; if you choose to ignore these errors, turn validation off with --validate=false
when I changed type to statefullstate it worked, but that's not what they want can someone assist here
