1. Deploy the redis-sentinel helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the Redis-Sentinel Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you will use the kubernetes package, which allows you to manage Kubernetes resources, including deploying Helm charts. Before you begin, ensure that you have access to an OKE cluster and that you have configured Pulumi with the appropriate credentials to interact with your Oracle Cloud Infrastructure (OCI) and the Kubernetes cluster.

    You will also need the Helm chart's repository URL and the chart name, which in this case is redis (the Redis-Sentinel chart is commonly packaged under the redis name, though it may vary by the repository).

    Here is how you can use Pulumi to deploy the Redis-Sentinel Helm chart:

    1. Import the necessary Pulumi and Kubernetes packages.
    2. Create a Chart resource, which represents the Helm chart you want to deploy.
    3. Provide the chart name, repository URL, and any custom values that you need to configure Redis-Sentinel.

    Below is the TypeScript program that defines the deployment:

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Initialize a new Pulumi project targeting the Kubernetes provider for OCI. const provider = new k8s.Provider('okeK8sProvider', { // kubeconfig can be set explicitly; otherwise, Pulumi uses the default kubeconfig from your local machine. // Ensure your Kubeconfig file is configured to connect to your OKE cluster. kubeconfig: process.env.KUBECONFIG, }); // Define the settings for the Redis-Sentinel deployment const redisSentinelChart = new k8s.helm.v3.Chart('redis-sentinel', { chart: 'redis', // This is the name of the chart in the repository. It may differ; please check for the exact name. version: 'x.x.x', // Specify the version of the Redis chart you wish to deploy, e.g., '10.5.7'. fetchOpts: { // Replace `repository_url` with the actual URL to the Helm repository that contains the Redis chart. repo: 'https://example.com/helm-charts', }, values: { // Here, you may specify any values that are needed to customize your Redis-Sentinel installation. // These values would correspond to the settings in the chart's `values.yaml` file. sentinel: { enabled: true, }, // Add any additional customization below as needed. }, }, { provider }); // Export the Redis service endpoint export const redisEndpoint = redisSentinelChart.getResourceProperty('v1/Service', 'redis-master', 'status') .apply(status => status.loadBalancer.ingress[0].ip);

    In this program:

    • We create a Provider to interact with the Kubernetes cluster on OKE. You need to ensure your local environment is configured with a kubeconfig that has access to the OKE cluster.
    • We then declare a Helm chart using new k8s.helm.v3.Chart. You should replace 'x.x.x' with the specific version of the Redis chart you wish to deploy and https://example.com/helm-charts with the appropriate repository URL.
    • The values field is used to configure the chart; you might need to change the settings to reflect your desired Redis-Sentinel configuration based on the content of the Helm chart's values.yaml file.
    • Finally, we export the redisEndpoint. This will give you the IP address of the Redis service after the deployment is successful so that you can connect to your Redis-Sentinel installation.

    You will need to install the Pulumi CLI and prepare your environment to run the program. Please ensure you have Node.js and NPM installed, and then follow these steps:

    1. Install the Pulumi CLI following the instructions on the Pulumi website.
    2. Set up your Pulumi project in a new directory by running pulumi new kubernetes-typescript.
    3. Copy the example program into your index.ts file.
    4. Replace the placeholders for the chart version and repository URL with actual values for the Redis-Sentinel Helm chart.
    5. Run npm install to install the necessary dependencies.
    6. Use pulumi up to deploy your Redis-Sentinel chart to the OKE cluster.

    Once launched, Pulumi will print the IP address of your Redis service that you can use to connect to your Redis-Sentinel installation.
