Warning

SingleStore 9.0 gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.

sdb-operator.yaml

This generates the Operator Deployment object that will spawn and maintain the Operator.

Create a deployment definition file using the template below.

The --cluster-id argument must match the name of the SingleStore custom resource as defined in the sdb-cluster.yaml ("sdb-cluster" by default). This value can be edited as long as these values match, so that the Operator knows which custom resource to manage.

          args: [
            # Cause the operator to merge rather than replace annotations on services
            "--merge-service-annotations",
            # Allow the process inside the container to have read/write access to the `/var/lib/memsql` volume.
            "--fs-group-id", "5555",
            "--cluster-id", "sdb-cluster"          ]
          env:
            - name: WATCH_NAMESPACE
              valueFrom:
                fieldRef:
                  fieldPath: metadata.namespace
            - name: POD_NAME
              valueFrom:
                fieldRef:
                  fieldPath: metadata.name
            - name: OPERATOR_NAME
              value: "sdb-operator"

You must edit this file and replace operator_image_tag with the either the local singlestore/operator Docker image you pulled down (such as "sdb-operator"), or add in an imagePullSecrets section under the spec section and reference a Kubernetes Secret that you can create via kubectl apply.

Refer to the Kubernetes documentation for more information on imagePullPolicy and creating Secrets.
