Deploy the yopass helm chart on Opensshift

Question

Pulumi · Accepted Answer

In this program, we will deploy the Yopass Helm chart on an OpenShift cluster using Pulumi with the `kubernetes` provider. Yopass (short for Your Own Password Service) is a project for sharing secrets in a secure and temporary manner.

To accomplish this, we will be utilizing the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider, which represents a chart from Helm, a package manager for Kubernetes. Helm charts allow you to define, install, and upgrade Kubernetes applications.

Here's a step-by-step explanation of the code:

1. **Pre-requisites**: Ensure that you have OpenShift CLI (`oc`) configured with your OpenShift cluster.
2. **Pulumi Kubernetes Provider**: We will configure the Kubernetes provider to communicate with the OpenShift cluster.
3. **Helm Chart Resource**: We will create an instance of `Chart` resource pointing to the Yopass Helm chart. We will specify any necessary values inline or through a YAML file, and set the release name and namespace for the deployment.

Now, let's look at the code to deploy Yopass on OpenShift:

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

const yopassChart = new k8s.helm.v3.Chart("yopass", {
    chart: "yopass",
    version: "1.0.0", // specify the exact chart version you want to deploy
    fetchOpts: {
        repo: "https://charts.yopass.se", // replace with the correct repo if it's been updated
    },
    namespace: "yopass", // replace with the desired namespace or use a namespace resource to create it
    // If the chart needs specific values, you may include them using 'values' field like below.
    // values: {
    //     key: "value",
    // },
}, { provider: openshiftProvider }); // assuming `openshiftProvider` is configured to point to your OpenShift cluster

export const yopassServiceUrl = yopassChart.getResourceProperty("v1/Service", "yopass", "status").apply(status => status.loadBalancer.ingress[0].hostname);
```

This program performs the following actions:
- It imports the necessary Pulumi Kubernetes package.
- It creates a new Helm chart instance for Yopass within a specified namespace in OpenShift.
- It exports the URL of the Yopass service so you can access it after deployment.

Make sure to replace `"1.0.0"` with the version of the Yopass chart you want to deploy, and `"https://charts.yopass.se"` with the correct repository URL if it has changed. Additionally, if the chart has required values (`values:` field), you need to specify them accordingly.

After writing this code to a file (e.g., `index.ts`), you would run `pulumi up` to execute the deployment. Remember that you need to have Pulumi installed and configured with the correct cloud credentials for your OpenShift environment.

This example assumes that you've set up a Kubernetes provider configured for your OpenShift cluster. If not, you would need to set up the provider, potentially using your kubeconfig if your cluster is already up and running. Pulumi will use your current kubeconfig context to deploy to the chosen cluster by default. If you need to target a specific context or cluster, you can configure the provider with additional options.
