Deploy the mayanedms helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Mayan EDMS Helm chart on Kubernetes using Pulumi, it's important to understand the overall process and what Pulumi resources we will use. We'll be using the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider, which allows us to deploy Helm charts into a Kubernetes cluster.

Here's the process we will follow:

Firstly, set up a Kubernetes cluster where you want to deploy the Mayan EDMS. For simplicity, we are assuming that you already have a cluster configured and a kubeconfig file ready to use with Pulumi.
Install the Pulumi CLI and set up your Pulumi program. Ensure you have Node.js installed as we will use TypeScript for writing the Pulumi program.
We will then define a Kubernetes Chart resource, referencing the Mayan EDMS Helm chart. We will specify the chart details such as the chart name, version, and any custom values that are needed to configure Mayan EDMS to our liking.

Now let's put this into code. Below is the Pulumi program that defines and deploys the Mayan EDMS Helm chart on your Kubernetes cluster.

import * as k8s from "@pulumi/kubernetes";

// Define the Mayan EDMS Helm chart from the repository where it is stored.
// Please replace 'chartVersion' with the desired chart version for Mayan EDMS.
const mayanEdmsChart = new k8s.helm.v3.Chart("mayan-edms", {
    // You might have to add the 'repo' property if Mayan EDMS is hosted in a specific Helm repository.
    chart: "mayan-edms",
    version: "<chartVersion>", // specify the exact chart version here
    // If you need to specify any custom values for your Mayan EDMS deployment, you can define them here.
    // For example, to change the service type to LoadBalancer and setting a tag:
    values: {
        service: {
            type: "LoadBalancer",
        },
        image: {
            tag: "latest",
        },
        // Add other customization values as needed.
    },
    // Define the namespace to deploy into, or remove this if you want to use the default namespace.
    namespace: "mayan-edms-namespace",
});

// Export relevant endpoints from the deployment, such as the cluster IP or load balancer IP (if used).
export const mayanEdmsEndpoint = mayanEdmsChart.getResourceProperty(
    "v1/Service", "mayan-edms", "status"
).apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

Replace <chartVersion> with the specific version of the Mayan EDMS chart you wish to deploy. If the Mayan EDMS chart you want to deploy is hosted in a Helm repository, you may also need to include the repo property to specify the location of the repository.

The values property is used to override the default chart values. In the example above, we are setting the service type to LoadBalancer, which exposes Mayan EDMS outside of the cluster. You might want to customize these values further based on your requirement.

Finally, we export the mayanEdmsEndpoint, which retrieves the IP address or hostname provided by the LoadBalancer service (if used) once Mayan EDMS is deployed. You can visit this endpoint in a browser to access your Mayan EDMS instance.

To execute this program, save it as index.ts and run pulumi up in the same directory. Pulumi will perform the deployment, and once finished, you'll see the endpoint to access Mayan EDMS in the outputs.
