Advanced Service Configuration

In addition to
objectMetaOverrides, you can specify the following options in this section:

LoadBalancer. Default is
loadBalancerIPis the IP address of the load balancer if you need to manage it.
loadBalancerSourceRangesspecifies the list of CIDR blocks to add to the load balancer.
externalTrafficPolicyspecifies if the service routes external network traffic to either node-local or cluster-wide endpoints. Valid options are
Cluster. Default is
headlessspecifies whether the service is a headless service or not. A headless service keeps track of its selected pods, but otherwise does not enable any network functionality.
If you need to specify these values, add the following section to the
memsql-cluster.yaml file as shown below.
serviceSpec: type: "LoadBalancer" loadBalancerIP: "220.127.116.11" loadBalancerSourceRanges: [ "0.0.0.0/0" ] externalTrafficPolicy: "Local" headless: false objectMetaOverrides: labels: custom: label annotations: custom: annotations
Refer to the Kubernetes documentation for more information about these attributes.
As of Operator 1.2.4, service creation can be disabled by setting the
disableDDLAndDMLService field to true in
serviceSpec. This will ignore all other fields in
serviceSpec, will not create new services, and will delete those services that were already created.
serviceSpec: disableDDLAndDMLService: true
