1. Deploy the label-studio helm chart on Opensshift


    To deploy the Label Studio Helm chart on OpenShift, we will use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows us to deploy Helm charts into a Kubernetes cluster, which in this case will be an OpenShift cluster. Before you begin, make sure you have access to an OpenShift cluster and that you have configured the kubectl command line tool to communicate with the cluster.

    The kubernetes.helm.v3.Chart resource requires several inputs, including the chart name, version, and values to customize the deployment as per Label Studio's Helm chart documentation. We'll start by defining the namespace where the Label Studio will be deployed. If the namespace does not exist, it will be created as part of the deployment process.

    When deploying to OpenShift, it's important to ensure that the required permissions and security context constraints (SCCs) are satisfied for the workloads. Depending on the Helm chart, additional setup might be needed, such as creating a ServiceAccount with the appropriate roles and assigning the right SCCs.

    Below is a TypeScript program that demonstrates how to deploy Label Studio using Pulumi on OpenShift.

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Set up the OpenShift provider configuration (assuming kubectl is configured) const clusterProvider = new k8s.Provider('openshift-k8s', { // You can specify the kubeconfig or other configuration here if needed }); // Create a namespace for Label Studio if it does not exist const namespace = new k8s.core.v1.Namespace('label-studio-ns', { metadata: { name: 'label-studio', // The namespace name where Label Studio will be deployed }, }, { provider: clusterProvider }); // Deploy Label Studio Helm chart into the namespace const labelStudioChart = new k8s.helm.v3.Chart('label-studio-chart', { chart: 'label-studio', version: '1.0.0', // Replace this with the desired version of the Label Studio Helm chart namespace: namespace.metadata.name, fetchOpts: { repo: 'https://helm.label-studio.com/', // Replace with the Label Studio Helm chart's repository URL }, // Values to configure Label Studio, these should match the chart's values.yaml structure // and should be defined according to your specific requirements for Label Studio. values: { // Add your custom values here }, }, { provider: clusterProvider }); // Export the URL to access Label Studio (if applicable) // If Label Studio provides a Service with a LoadBalancer or creates an Ingress, you can export the URL as needed. export const labelStudioUrl = 'http://...'; // Replace this with the actual access endpoint

    Replace the values such as version, and the content of values to match your specific Label Studio Helm chart version and configuration requirements. The URL to access Label Studio after deployment will depend on how the service is exposed, which could be through an OpenShift Route, Ingress, or LoadBalancer service.

    Make sure to carefully review the Label Studio Helm chart's documentation to understand all the configurable parameters and adjust them according to your needs.

    This Pulumi program does the following:

    • Sets up a Kubernetes provider to interact with your OpenShift cluster.
    • Creates a new Kubernetes Namespace for your Label Studio deployment.
    • Deploys Label Studio using the Helm chart, referencing the chart and its repository.

    To use this program:

    1. Make sure Pulumi is installed and set up for TypeScript.
    2. Create a new TypeScript Pulumi project if you haven't already.
    3. Replace the placeholder values in the code with your actual details.
    4. Run pulumi up to preview and deploy the changes.

    If the Label Studio Helm chart requires additional permissions, ensure they are met within the Helm values or by pre-configuring OpenShift with the necessary ServiceAccounts and SCCs.
