Using kubernetes operator.tigera.io with metallb.io

Question

Pulumi · Accepted Answer

To create a Kubernetes infrastructure that includes the Tigera operator and MetalLB, you would typically need to:

1. Set up a Kubernetes cluster.
2. Install the Tigera operator to manage networking components for Kubernetes.
3. Install MetalLB to provide load-balancer implementation for services of type LoadBalancer.

For simplicity, I'll assume you already have a Kubernetes cluster and are focusing on deploying Tigera and MetalLB into the cluster. It's important to note that specific YAML configurations for each piece of software will depend on the specific network and cluster configurations you have. However, I'll provide a general Pulumi TypeScript program that shows how to apply Kubernetes manifest files for both Tigera and MetalLB.

Below is the TypeScript program that demonstrates how to use Pulumi to deploy Tigera operator and MetalLB into your Kubernetes cluster:

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

// We will start by creating a new Pulumi Kubernetes provider based on our current kubeconfig. This provider will drive the deployment to our cluster.
const provider = new k8s.Provider('k8s-provider', {
    kubeconfig: '<Your KUBECONFIG>'
});

// Here we deploy the Tigera operator. We have to make sure we have the right manifest URL or file for the Tigera operator to be applied to our cluster.
const tigeraOperator = new k8s.yaml.ConfigFile('tigera-operator', {
    file: 'https://docs.tigera.io/manifests/tigera-operator.yaml', // This URL may change based on Tigera's documentation
}, { provider: provider });

// Once the Tigera operator is up and running, we need to apply the custom resource definitions required by Tigera.
const tigeraInstall = new k8s.yaml.ConfigFile('tigera-installation', {
    file: 'https://docs.tigera.io/manifests/custom-resources.yaml', // This is a Tigera installation example, ensure you have the correct URL or file.
    dependsOn: [tigeraOperator] // This ensures that the Tigera operator is created before applying this configuration.
}, { provider: provider });

// Next, we'll install MetalLB into our cluster. Again, make sure you have the correct manifest URL or file for MetalLB.
const metalLB = new k8s.yaml.ConfigFile('metallb', {
    file: 'https://raw.githubusercontent.com/metallb/metallb/v0.9.6/manifests/metallb.yaml', // Replace with the proper version for MetalLB.
    dependsOn: [tigeraInstall] // Optional: To ensure Tigera is set up before MetalLB, though they are independent.
}, { provider: provider });

// We may need to configure MetalLB with a config map to assign a range of IP addresses for the load balancer. Adjust according to your network configuration.
const metallbConfig = new k8s.core.v1.ConfigMap('metallb-config', {
    metadata: {
        namespace: 'metallb-system', // Make sure this is the namespace MetalLB is deployed in.
        name: 'config'
    },
    data: {
        'config': `
            address-pools:
            - name: default
              protocol: layer2
              addresses:
              - 192.168.1.240/28  // Replace with the IP range for your network.
        `,
    },
}, { provider: provider, dependsOn: [metalLB] });

// Exports the names of the resources. You can add other exports as needed.
export const tigeraOperatorName = tigeraOperator.metadata.apply(m => m.name);
export const tigeraInstallName = tigeraInstall.metadata.apply(m => m.name);
export const metalLBName = metalLB.metadata.apply(m => m.name);
export const metallbConfigName = metallbConfig.metadata.apply(m => m.name);
```

This code demonstrates deploying both Tigera and MetalLB using Pulumi. It does so by applying the manifests directly from their official sources, or you can download the YAML files to customize them before deploying.

For more information about the `ConfigFile` class, check the [Pulumi Kubernetes YAML](https://www.pulumi.com/registry/packages/kubernetes/api-docs/yaml/configfile/) documentation. Keep in mind that the YAML files from external sources might change, so be sure to refer to the official Tigera and MetalLB documentation for the most current manifest files.
