1. Deploy the redis-sentinel helm chart on Rancher


    In order to deploy the redis-sentinel Helm chart on a Rancher-managed Kubernetes cluster, you'd typically follow these steps:

    1. Set up and configure access to your Rancher instance, which can be done through the Rancher API, CLI, or UI. You would need appropriate permissions to deploy applications to the cluster.
    2. Ensure you have a Kubernetes cluster managed by Rancher and that you have kubectl access to this cluster.
    3. Use the Kubernetes provider in Pulumi to interact with your Kubernetes cluster and deploy the Helm chart.

    Unfortunately, the Pulumi Registry Results provided do not include a direct match for deploying Helm charts via the Rancher 2 Pulumi provider. However, you can achieve the deployment using the Pulumi Kubernetes provider.

    Below is a Pulumi TypeScript program that demonstrates how to deploy the redis-sentinel Helm chart onto a Kubernetes cluster managed by Rancher. Keep in mind that you must have kubectl access to the target Rancher Kubernetes cluster, and that kubectl is configured to point to the correct cluster context.

    import * as k8s from "@pulumi/kubernetes"; // Create a provider to interact with your Kubernetes cluster. // Assumes `kubectl` is configured to point to your Rancher-managed cluster. const provider = new k8s.Provider("k8s-provider", { // `context` refers to the context from your kubeconfig (i.e., the name of the cluster as seen by kubectl). context: "rancher-cluster-context", }); // Deploy the redis-sentinel Helm chart using the Kubernetes provider. const redisSentinelRelease = new k8s.helm.v3.Release("redis-sentinel", { chart: "redis", repositoryOpts: { repo: "https://charts.bitnami.com/bitnami", }, // You can specify the Helm chart version you want to deploy, like "12.7.8". version: "chart-version", // Custom values: enable sentinel in Redis chart values. values: { sentinel: { enabled: true, }, }, }, { provider }); // Export the name of the deployed Redis Sentinel release. export const releaseName = redisSentinelRelease.status.name;

    In this program:

    • We import the @pulumi/kubernetes package which allows us to interact with Kubernetes clusters.
    • We create a Kubernetes provider instance that uses the kubeconfig context for the Rancher-managed cluster (rancher-cluster-context). You should replace this with the actual context name for your cluster.
    • We deploy a Helm release that references the Redis chart from Bitnami's Helm repository. This will deploy Redis with Sentinel enabled, as indicated by the values parameter.
    • We export the releaseName so that you can easily retrieve the name of the deployed release after running the Pulumi program.

    To use this program, place it in a file named index.ts in your Pulumi project directory. Ensure that Pulumi.yaml and Pulumi.<stack-name>.yaml are properly configured for TypeScript and that you have all the necessary dependencies installed via npm (@pulumi/kubernetes and @pulumi/pulumi).

    Run pulumi up within that directory to deploy the Redis Sentinel Helm chart to your Rancher-managed Kubernetes cluster.
