1. Deploy the mysql8 helm chart on Digital Ocean Kubernetes Service


    To deploy the MySQL 8 Helm chart on a Digital Ocean Kubernetes Service (DOKS) using Pulumi, we'll perform the following actions:

    1. Create a DOKS cluster: We'll first declare necessary resources to define a Digital Ocean Kubernetes cluster.
    2. Deploy the MySQL Helm chart: Once we have our cluster, we'll deploy MySQL 8 using its Helm chart.

    For this demonstration, I'll provide you with a Pulumi TypeScript program which comprises these steps. I'll use the @pulumi/digitalocean and @pulumi/kubernetes packages. The KubernetesCluster resource will create a cluster in Digital Ocean, and the Chart resource from the @pulumi/kubernetes/helm module is responsible for deploying Helm charts into a Kubernetes cluster.

    Here's how you do it:

    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, }, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Create a provider for the DigitalOcean Kubernetes cluster. const k8sProvider = new k8s.Provider('do-k8s', { kubeconfig: kubeconfig, }); // Deploy MySQL 8 using the Helm chart. const mysqlChart = new k8s.helm.v3.Chart('mysql-chart', { chart: 'mysql', version: '8.8.2', fetchOpts: { repo: 'https://charts.bitnami.com/bitnami' }, }, { provider: k8sProvider }); // Export the name of the cluster export const clusterName = cluster.name; // Export the MySQL service endpoint export const mysqlServiceEndpoint = mysqlChart.getResource("v1/Service", "default/mysql-chart").status.apply(s => `mysql://${s.loadBalancer.ingress[0].ip}`);

    In this program:

    • We create a DigitalOcean Kubernetes cluster with a single default node pool. You can customize the cluster size, node count, and other settings as needed.
    • We export the cluster's kubeconfig, which allows us to interact with the cluster using tools like kubectl.
    • We create a Pulumi Kubernetes provider that uses the kubeconfig of our DigitalOcean cluster. This provider is necessary to deploy Kubernetes resources to this particular cluster.
    • We deploy MySQL using its Helm chart provided by Bitnami. We specify the chart name (mysql), version (8.8.2), and repository URL (Bitnami's Helm repo).
    • We export the name of the cluster, which can be used for future references.
    • Additionally, we export the MySQL service endpoint, which should generally be an IP address you can use to connect to MySQL from outside the cluster after it has been deployed.

    This program assumes you have Pulumi installed and configured for use with DigitalOcean. You'll need to create a new Pulumi project, set it up for TypeScript, and install the required packages using npm:

    # Create a new Pulumi project directory mkdir pulumi-mysql-doks && cd pulumi-mysql-doks # Start a new Pulumi project for Typescript pulumi new typescript # Then install the DigitalOcean and Kubernetes packages npm install @pulumi/digitalocean @pulumi/kubernetes

    Next, replace the contents of index.ts with the provided TypeScript program.

    To deploy this stack, simply run pulumi up in the terminal within the Pulumi project directory. This instructs Pulumi to provision the resources as described in your TypeScript program.

    Remember, managing cloud resources often incurs costs, so be sure to delete resources you no longer need by running pulumi destroy.

    For additional details, you can check out the Pulumi documentation for DigitalOcean Kubernetes Clusters and the Helm Chart Resource.
