1. Deploy the mautrix-telegram helm chart on Digital Ocean Kubernetes Service


    To deploy the mautrix-telegram Helm chart on DigitalOcean Kubernetes Service using Pulumi, we will take the following steps:

    1. Create a DigitalOcean Kubernetes cluster.
    2. Deploy the mautrix-telegram Helm chart to the cluster.

    We'll use two main Pulumi resources for this task:

    • digitalocean.KubernetesCluster: It represents a Kubernetes cluster on DigitalOcean, and we'll configure it with the desired region, node pool size, and other necessary parameters.
    • kubernetes.helm.sh/v3.Chart: It represents a Helm chart deployment in a Kubernetes cluster, and we'll use it to specify the mautrix-telegram Helm chart and configure its settings.

    Here is how you can do it using TypeScript:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Create a new DigitalOcean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', // Change to your desired DigitalOcean region version: 'latest', // Specify the desired Kubernetes version nodePool: { name: 'default', // Name for the node pool size: 's-2vcpu-2gb', // The size slug indicating the kind of Droplet to use as workers nodeCount: 2, // The number of Droplet instances in the node pool }, }); // Create a new Kubernetes provider that uses the latest Kubeconfig from our cluster. const k8sProvider = new k8s.Provider('do-k8s', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the mautrix-telegram Helm chart to the DigitalOcean Kubernetes cluster. const mautrixTelegramChart = new k8s.helm.v3.Chart('mautrix-telegram', { chart: 'mautrix-telegram', version: '0.1.0', // Use the specific version of the chart; otherwise, omit to use the latest namespace: 'default', // Specify the Kubernetes namespace to deploy into fetchOpts: { // Configure Helm repository options here if needed repo: 'https://mau.dev/mautrix/helm/', // Replace with the repository containing mautrix-telegram chart }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // After running `pulumi up`, the DigitalOcean Kubernetes cluster will be created, // and the mautrix-telegram Helm chart will be deployed to it.

    In the above code:

    • We create a DigitalOcean Kubernetes cluster with a specific region, version, and node pool size.
    • We create a Pulumi Kubernetes provider that uses the kubeconfig from our new DigitalOcean Kubernetes cluster.
    • We deploy the mautrix-telegram Helm chart from its Helm repository to the default namespace in our Kubernetes cluster.

    After writing this code to a index.ts file within your Pulumi project, you can use the Pulumi CLI to deploy the resources. Run pulumi up, and Pulumi will handle the creation of these resources on DigitalOcean and within the Kubernetes cluster.

    Ensure that you have the Pulumi CLI installed and set up with your DigitalOcean API token. Additionally, you need an existing Pulumi project to run this code. If you don't have a project set up yet, you can quickly create one using the Pulumi CLI and following its project setup instructions.

    Lastly, please verify the Helm chart name and version along with the location of the Helm repository for mautrix-telegram. The provided repo URL must be replaced with the actual Helm repository where the mautrix-telegram chart is hosted. If you are unsure about these details, consult the documentation or source where you found the chart.
