1. Deploy the onedev helm chart on Rancher

    TypeScript

    To deploy the OneDev Helm chart on a Rancher-managed Kubernetes cluster, you will need to perform several steps using Pulumi. First, we will set up the necessary Rancher resources, create a Kubernetes cluster using Rancher, and then deploy the OneDev Helm chart to the cluster.

    Here's a high-level overview of the steps involved:

    1. Setup Rancher: You need a running instance of Rancher. Ensure you have access to the Rancher server and the Kubernetes cluster where Rancher is deployed.

    2. Rancher2 Provider: Set up the Pulumi Rancher2 provider to manage resources in Rancher.

    3. Create or Access Cluster: You need access to a Kubernetes cluster managed by Rancher. This can be an existing cluster or you may use Pulumi to create a new one.

    4. Install Helm Chart: Once you have a Kubernetes cluster, you can use Pulumi to deploy the OneDev Helm chart on it.

    5. Verify Deployment: After the deployment, you may want to verify that OneDev has been successfully deployed and is running.

    Please note that this guide assumes you have Pulumi installed and configured for use with your cloud provider. Also, ensure that you have appropriate permissions in Rancher to create resources and deploy Helm charts.

    Let's begin with a Pulumi TypeScript program that executes the steps mentioned:

    import * as rancher2 from "@pulumi/rancher2"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; const name = "onedev"; // Step 1: Configure the Rancher2 provider with the necessary credentials // Replace the placeholders with your actual Rancher access credentials const rancherProvider = new rancher2.Provider("rancher", { apiURL: "https://<RANCHER_SERVER_URL>", accessToken: "<RANCHER_ACCESS_TOKEN>", secretKey: "<RANCHER_SECRET_KEY>", }); // Step 2: Access an existing Kubernetes cluster or create a new one using Rancher // This example shows how you might access an existing cluster - replace `clusterId` with your actual cluster ID const cluster = rancher2.getCluster({ clusterId: "<RANCHER_CLUSTER_ID>", }, { provider: rancherProvider }); // Step 3: Deploy the OneDev Helm chart once the cluster is ready // Please replace `repoUrl` with the URL of the OneDev Helm chart repository const onedevHelmChart = new kubernetes.helm.v3.Chart(name, { chart: "onedev", version: "<CHART_VERSION>", // Specify the version of OneDev Helm chart you want to deploy fetchOpts:{ repo: "<HELM_CHART_REPO_URL>", }, }, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigRaw }) }); // Export the OneDev Helm release status export const onedevHelmStatus = onedevHelmChart.status;

    Explanation:

    • We import the necessary Pulumi packages for Rancher and Kubernetes.
    • We use the rancher2.Provider to configure our connection to the Rancher API, replacing the placeholders with your own credentials (apiURL, accessToken, and secretKey).
    • We then get the Kubernetes cluster managed by Rancher either by referencing an existing one or creating a new one.
    • With access to the cluster, we create a Pulumi Kubernetes provider instance with the kubeconfig of the cluster.
    • Using the kubernetes.helm.v3.Chart resource, we deploy the OneDev Helm chart to the cluster.

    Please replace <RANCHER_SERVER_URL>, <RANCHER_ACCESS_TOKEN>, <RANCHER_SECRET_KEY>, and <RANCHER_CLUSTER_ID> with your actual values for the Rancher server access credentials and the ID of the Kubernetes cluster managed by Rancher. Additionally, set the repoUrl to the URL of the OneDev Helm chart repository.

    After running this program with pulumi up, Pulumi will communicate with Rancher to deploy OneDev to the specified cluster. If successful, it will output the status of the Helm chart deployment, which you can use to verify OneDev is running as expected.

    Remember to check the specific version of the OneDev Helm chart you wish to install and to ensure that the Helm repository URL is correct.
