Using kubernetes k8s.keycloak.org with falcon.crowdstrike.com

Question

Pulumi · Accepted Answer

In the scenario where you want to integrate Keycloak on Kubernetes with CrowdStrike Falcon for security, you would typically proceed in the following manner:

1. Deploy a Keycloak instance on Kubernetes
2. Configure Keycloak with the appropriate authentication flows, realms, and client settings.
3. Integrate CrowdStrike Falcon by making use of Keycloak's support for external identity providers or using CrowdStrike's APIs for custom federation, as needed.

Since Pulumi does not have a ready-made integration between Keycloak and CrowdStrike Falcon, much of the CrowdStrike specific configuration would need to be handled outside of Pulumi, possibly with API calls to CrowdStrike or custom Keycloak plugins. However, we can set up a Keycloak instance on Kubernetes using Pulumi with the Keycloak provider. Here, I'll demonstrate how to do that part.

First, ensure you have a Kubernetes cluster up and running, and that your Pulumi environment is properly configured to interact with that cluster. Here is a basic Pulumi program in TypeScript to deploy a Keycloak instance on your Kubernetes cluster:

```typescript
import * as k8s from '@pulumi/kubernetes';
import * as pulumi from '@pulumi/pulumi';

// Create a Kubernetes namespace for Keycloak
const keycloakNamespace = new k8s.core.v1.Namespace("keycloak-namespace", {
    metadata: {
        name: "keycloak"
    }
});

// Define the Keycloak deployment configuration
const keycloakDeployment = new k8s.apps.v1.Deployment("keycloak-deployment", {
    metadata: {
        namespace: keycloakNamespace.metadata.name,
    },
    spec: {
        selector: { matchLabels: { app: "keycloak" } },
        replicas: 1,
        template: {
            metadata: { labels: { app: "keycloak" } },
            spec: {
                containers: [{
                    name: "keycloak",
                    image: "jboss/keycloak", // You may want to pin this to a specific version.
                    env: [
                        { name: "KEYCLOAK_USER", value: "admin" }, // Replace 'admin' with your admin username.
                        { name: "KEYCLOAK_PASSWORD", value: "password" }, // Replace 'password' with your admin password.
                        // Add any other environment variables as needed.
                    ],
                    ports: [{ containerPort: 8080 }],
                }],
            },
        },
    },
}, { dependsOn: [keycloakNamespace] });

// Export the Keycloak endpoint to access the admin console
export const keycloakAdminConsoleUrl = pulumi.interpolate`http://${keycloakDeployment.metadata.name}.${keycloakNamespace.metadata.name}.svc.cluster.local:8080`;

```

This Pulumi program deploys Keycloak within a new namespace in your Kubernetes cluster using a basic configuration. Here are a few things to consider:

- The `NAMESPACE` reflects where Keycloak will live within your Kubernetes cluster. It's generally a good practice to isolate services within their own namespaces.
- The `DEPLOYMENT` sets up Keycloak with a single replica; however, for a production environment, you would want to consider a more resilient configuration.
- Environment variables are set for Keycloak's admin credentials. In a production environment, these should be securely managed and not hard-coded.
- The `Service` and `Ingress` resources that would expose Keycloak externally have been left out for simplicity but would be needed to connect to Keycloak from outside your Kubernetes cluster.
- CrowdStrike Falcon integration would likely involve API calls or additional configuration that is not shown here.

Remember to replace `"admin"` and `"password"` with your actual admin username and password. Do not hardcode these values for a real-world deployment; use a secret management solution instead.

After you've applied this configuration with Pulumi and have your Keycloak instance up and running, you would need to manually integrate with CrowdStrike Falcon, using CrowdStrike's solutions for securing identity providers or similar. You will need to follow CrowdStrike Falcon's documentation for this part of the setup.
