1. Using kubernetes monitoring.grafana.com with secrets.hashicorp.com

    TypeScript

    Integrating Kubernetes monitoring with Grafana and managing secrets with HashiCorp's Vault involves several steps. I'll guide you on setting up a basic Pulumi program that creates a Grafana Kubernetes resource and configures HashiCorp Vault for secrets management.

    The goal is to use Grafana for Kubernetes monitoring properly, which can be achieved by setting up Grafana datasources and dashboards that will connect to your Kubernetes cluster's monitoring endpoints (like Prometheus). For managing secrets, such as API keys or credentials, HashiCorp's Vault is often used as a secure store.

    To manage these resources, Pulumi provides the grafana and kubernetes packages that allow you to declare desired state configuration for Grafana and Kubernetes, respectively. Pulumi also integrates with various secret providers, including HashiCorp's Vault, which you can set up as a backend for secret storage.

    Below is the Pulumi TypeScript program that lays the groundwork:

    import * as pulumi from '@pulumi/pulumi'; import * as kubernetes from '@pulumi/kubernetes'; import * as grafana from '@pulumi/grafana'; // Initialize a Kubernetes provider instance, configuring it to connect to your cluster. const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: "<KUBECONFIG_CONTENT>", }); // Create a Grafana DataSource for Kubernetes, assuming you have Prometheus deployed in your cluster. const prometheusDataSource = new grafana.DataSource("prom-k8s", { type: "prometheus", url: "http://prometheus-server.<NAMESPACE>.svc.cluster.local", // Replace <NAMESPACE> with the actual namespace where Prometheus is deployed. accessMode: "proxy", isDefault: true, jsonData: { "tlsAuth": false, "tlsAuthWithCACert": false, }, }, { provider: k8sProvider }); // Output the Prometheus Grafana data source name. export const prometheusDataSourceName = prometheusDataSource.name;

    Explanation:

    1. Kubernetes Provider: The kubernetes.Provider object is initialized to set up the connection to your Kubernetes cluster.

    2. Grafana DataSource: The grafana.DataSource object represents a Grafana data source for Prometheus. In the provided code, it's set up to point to a Prometheus server that should already be running inside your cluster. The url field should be updated to use the correct service endpoint for Prometheus in your cluster.

    3. Outputs: The prometheusDataSourceName is exported so that you can easily reference the created Grafana data source name outside of Pulumi.

    Managing Secrets with HashiCorp Vault:

    The Pulumi program above assumes that you've configured Pulumi to use HashiCorp Vault for secret storage. This is done outside of the code with the Pulumi CLI. Here's how you set up HashiCorp Vault with Pulumi:

    1. Install Vault: Follow HashiCorp's Vault installation guide to set up Vault in your environment.

    2. Configure Pulumi to Use Vault: In your terminal, run the following command to set the Pulumi secret provider to Vault:

      pulumi config set --secret-provider="vault://<VAULT_SERVER_URL>"

    Replace <VAULT_SERVER_URL> with the address to your Vault server.

    1. Storing Secrets in Vault: Now, you'll be able to store your secrets directly in Vault, and reference them within your Pulumi program through the Pulumi secret management feature.

    If you need specific guidance on setting up the Grafana dashboard or integrating more Kubernetes services for monitoring, please provide more details or clarifications. This program is just a starting point and may need to be adjusted based on your particular setup and requirements.
