  2. Deploying SpiceDB Cluster for Secure Multi-Tenant AI Services on Kubernetes

How do I deploy a SpiceDB cluster for secure multi-tenant AI services on Kubernetes?

In this guide, we will deploy a SpiceDB cluster on Kubernetes to provide secure multi-tenant AI services. SpiceDB is a database for managing permissions and access control, which is essential for multi-tenant applications. We will use Pulumi to define and manage our Kubernetes resources.

Key Points

  • Use Pulumi to define Kubernetes resources.
  • Deploy SpiceDB on Kubernetes for secure multi-tenant AI services.
  • Utilize ConfigMap, StatefulSet, and Service to configure and manage the SpiceDB cluster.
import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Define a ConfigMap for SpiceDB configuration
const spicedbConfig = new k8s.core.v1.ConfigMap("spicedb-config", {
    metadata: { name: "spicedb-config" },
    data: {
        "spicedb.conf": `
        log_level = "debug"
        grpc_no_tls = true
        http_no_tls = true
        `,
    },
});

// Define a StatefulSet for SpiceDB
const spicedbStatefulSet = new k8s.apps.v1.StatefulSet("spicedb", {
    metadata: { name: "spicedb" },
    spec: {
        serviceName: "spicedb",
        replicas: 3,
        selector: { matchLabels: { app: "spicedb" } },
        template: {
            metadata: { labels: { app: "spicedb" } },
            spec: {
                containers: [{
                    name: "spicedb",
                    image: "quay.io/authzed/spicedb:latest",
                    ports: [{ containerPort: 50051, name: "grpc" }, { containerPort: 8443, name: "http" }],
                    volumeMounts: [{ name: "config-volume", mountPath: "/etc/spicedb" }],
                }],
                volumes: [{
                    name: "config-volume",
                    configMap: { name: "spicedb-config" },
                }],
            },
        },
    },
});

// Define a Service to expose SpiceDB
const spicedbService = new k8s.core.v1.Service("spicedb-service", {
    metadata: { name: "spicedb-service" },
    spec: {
        selector: { app: "spicedb" },
        ports: [
            { port: 50051, targetPort: "grpc", protocol: "TCP", name: "grpc" },
            { port: 8443, targetPort: "http", protocol: "TCP", name: "http" },
        ],
    },
});

// Export the service URL
export const spicedbServiceUrl = spicedbService.status.apply(s => `http://${s.loadBalancer.ingress[0].ip}:8443`);

Summary

In this guide, we deployed a SpiceDB cluster on Kubernetes using Pulumi. We created a ConfigMap for SpiceDB configuration, a StatefulSet to manage the SpiceDB instances, and a Service to expose SpiceDB for external access. This setup ensures secure and scalable multi-tenant AI services.
