Deploy the gogs helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Gogs Helm chart on a Kubernetes cluster using Pulumi, you'll need to create a Pulumi program in TypeScript. This program will interact with your Kubernetes cluster to install the Helm chart, which will set up Gogs, a self-hosted Git service.

Below are the main steps that the Pulumi program will go through:

1. Import necessary Pulumi and Pulumi Kubernetes packages.
2. Create a Helm chart resource using the `Chart` class from the `@pulumi/kubernetes/helm` package.
3. Specify the chart name, repository, and any additional configuration options or overrides that you want to apply to the deployment.

Below is the Pulumi TypeScript program that accomplishes this. Make sure your Kubernetes cluster is correctly configured in your environment for Pulumi to interact with it (e.g., the appropriate Kubeconfig file is in place).

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

const gogsChart = new k8s.helm.v3.Chart('gogs', {
    // Use the "stable" Helm repo URL
    repo: 'https://charts.helm.sh/stable',
    chart: 'gogs',
    // Specify the version of the Helm chart you want to deploy
    version: '1.1.1',
    // Specify any values you want to override
    // refer to the chart's values.yaml for the full list of options
    values: {
        // For example, to set a service type to "LoadBalancer" you could uncomment the next line:
        // serviceType: "LoadBalancer",
    },
});

// Export the deployment name of the chart
export const chartName = gogsChart.metadata.name;
```

Here's a breakdown of what the code does:

- We import the Kubernetes package from Pulumi to operate Kubernetes resources.
- We create a `Chart` resource, which Pulumi uses to install and manage Helm charts. Here, you provide the name `gogs` for the chart, which corresponds to the Gogs Helm chart within the specified Helm repository.
- The `repo` option specifies the URL of the Helm chart repository.
- The `chart` option specifies the name of the chart in the repository you want to deploy (`gogs` in this case).
- The `version` option allows you to specify a particular chart version to deploy. Replace `'1.1.1'` with the desired version, or omit this line for the latest version.
- The `values` key allows you to specify configuration values that override the defaults in the `values.yaml` supplied with the Helm chart. In this case, it's commented out, but you can uncomment and modify it according to your needs (e.g., service type).
- Finally, we export the name of the deployment so that you can easily identify the chart that was deployed when working with the Pulumi CLI or Pulumi Service.

Please note:
- The namespace in which this chart will be deployed is not specified, which means it will be deployed to the default namespace unless you set the `namespace` option in the `Chart` resource.
- Before running this program, ensure the specified repository (`https://charts.helm.sh/stable`) contains the Gogs Helm chart, and the version is correct. As repositories and versions could change, it might be required to check the up-to-date repository URL and the available chart versions.
- The `serviceType` is set in the `values` object as an example of setting an override value. Depending on your cluster and requirements, you might choose a different service type or additional overrides.
- To run and manage this Pulumi program, you would typically use the Pulumi CLI. It allows you to create, update, and destroy cloud resources according to the declarations in your Pulumi program's code.

This code provides a template for deploying a Gogs Helm chart, which you can customize further based on the specific requirements for your Gogs setup.
