1. Deploy the goalert helm chart on Digital Ocean Kubernetes Service


    Deploying a Helm chart to a Kubernetes cluster involves several steps: creating the cluster, setting up the necessary configurations, and deploying the Helm chart itself. In this Pulumi program in TypeScript, we'll go through creating a DigitalOcean Kubernetes (DOKS) cluster, and then deploying the goalert Helm chart to it.

    First, we create a DigitalOcean Kubernetes cluster using digitalocean.KubernetesCluster which is a resource that provisions a Kubernetes cluster on DigitalOcean's cloud infrastructure. The minimal required properties for this resource include the name, region, version, and node pool configuration.

    After setting up the cluster, we'll use the kubernetes.helm.v3.Chart resource from the Kubernetes provider to deploy the goalert Helm chart to our newly created cluster. This resource is a representation of a Helm chart in Pulumi which allows you to deploy, upgrade, and manage Helm charts and their releases.

    Lastly, we need to set up a provider that specifies how to connect to the DigitalOcean Kubernetes cluster. A Kubernetes provider resource needs the kubeconfig file of the DOKS cluster to interact with it.

    Below is the Pulumi program that accomplishes these tasks:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', version: '1.21.5-do.0', nodePool: { name: 'default', size: 's-2vcpu-2gb', nodeCount: 1, }, }); // Create a Kubernetes provider instance using the cluster's kubeconfig const k8sProvider = new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the goalert Helm chart to the DigitalOcean Kubernetes cluster const goalertChart = new k8s.helm.v3.Chart('goalert', { chart: 'goalert', version: 'x.y.z', // specify the version of the chart fetchOpts: { repo: 'https://example.com/helm-charts', // specify the Helm chart repository }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    In this code block, make sure to replace the placeholder values like x.y.z with the actual version number of the goalert Helm chart you want to deploy, and https://example.com/helm-charts with the correct Helm repository URL that hosts the goalert chart.

    Also ensure to select the appropriate region, Kubernetes version, and node size for the digitalocean.KubernetesCluster resource based on your requirements and the availability in your DigitalOcean account.

    After deploying this program with Pulumi by running pulumi up, you will have a new DigitalOcean Kubernetes cluster running with the goalert Helm chart deployed on it. The exported kubeconfig can be used with kubectl to interact with your Kubernetes cluster and manage your Helm chart deployment.
