Deploy the OneUptime helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the OneUptime helm chart on an OpenShift cluster using Pulumi, you would need to follow a series of steps. First, ensure that you have an OpenShift cluster running and accessible. Then you can use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes Provider, which allows you to deploy Helm charts within a Kubernetes cluster.

Here's a program written in TypeScript that demonstrates how to deploy a Helm chart to an OpenShift cluster. We will use Pulumi's Kubernetes Provider to configure and deploy the OneUptime helm chart. Make sure you have the Helm chart's repository URL and any necessary configurations specific to OneUptime.

Before we start, be sure that you have the Pulumi CLI installed, and you're logged into a Pulumi account where you can create and manage Pulumi stacks. Also, you should have `kubectl` configured to connect to your OpenShift cluster.

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

// Create a provider for the existing OpenShift cluster.
const openshiftProvider = new k8s.Provider("openshift", {
  // You should configure the `kubeconfig` to point to your OpenShift cluster.
  // This is typically taken from a file, or from the environment variable `KUBECONFIG`.
  kubeconfig: process.env.KUBECONFIG,
});

// Define the OneUptime Helm chart from its repository.
const oneUptimeChart = new k8s.helm.v3.Chart("oneuptime", {
  // Replace with the correct repository URL and chart name for OneUptime.
  repo: "oneuptime-repo",
  chart: "oneuptime",
  values: {
    // Define any values that you need to override. For example:
    service: {
      type: "ClusterIP",
    },
  },
  // Specify the OpenShift namespace where you want to deploy.
  namespace: "oneuptime-namespace",
}, { provider: openshiftProvider });

// Export any properties that might be useful to know after the deployment.
export const oneUptimeChartStatus = oneUptimeChart.status;
```

In this code:

- We first import the necessary Pulumi libraries for Kubernetes.
- We create an instance of `Provider` which allows us to communicate with our OpenShift cluster.
- We declare the `oneuptime` Helm chart we want to install, including:
  - The chart name (`chart`): this should be the name of the OneUptime chart as found in its repository.
  - The repository (`repo`): this should be the URL where the OneUptime chart can be found.
  - Any custom values (`values`) you want to override for this chart.
  - The namespace (`namespace`): the namespace in OpenShift where you want to deploy OneUptime. Make sure this namespace exists in your cluster.
- We provide the OpenShift provider to the chart so that it will be deployed to the OpenShift cluster.
- Lastly, we export the status of the Helm chart so you can see its output once it's deployed.

Before running the Pulumi program, make sure your Pulumi stack is set to the appropriate environment that targets your Openshift cluster. You can run this program by executing `pulumi up`, which will prompt you to confirm the deployment before it proceeds.

If `oneuptime` Helm chart or `oneuptime-repo` Helm repository mentioned in the above code are placeholders, and you will need to replace them with actual values provided by the Helm chart maintainer or your own repository configurations. If you are unsure about the correct configuration values, you can often find examples in the Helm chart's documentation or by contacting the maintainers of the OneUptime Helm chart.
