Deploy the opensips helm chart on Kubernetes
TypeScriptTo deploy the OpenSIPS Helm chart on a Kubernetes cluster using Pulumi and TypeScript, you'll need to create a Pulumi project, make sure that
kubectl
is configured to connect to your Kubernetes cluster, and install the@pulumi/kubernetes
package, which allows you to interact with Kubernetes resources.The program below demonstrates how to accomplish this task using the
Chart
resource from the@pulumi/kubernetes
package. This will deploy the OpenSIPS Helm chart into the Kubernetes cluster associated with the context in your localkubectl
configuration.Install the necessary Pulumi package:
npm install @pulumi/kubernetes
Here is the Pulumi TypeScript program:
import * as k8s from "@pulumi/kubernetes"; // Allocate a namespace for the OpenSIPS Helm chart const namespace = new k8s.core.v1.Namespace("opensips-ns", { metadata: { name: "opensips", }, }); // Deploy OpenSIPS Helm chart using the Chart resource const openSipsChart = new k8s.helm.v3.Chart("opensips", { chart: "opensips", version: "1.0.0", // Replace with the desired chart version namespace: namespace.metadata.name, fetchOpts: { repo: "http://myhelmrepo.com/", // Replace with the Helm repository URL that hosts the OpenSIPS chart }, }, { dependsOn: [namespace] }); // Export the namespace name export const opensipsNamespace = namespace.metadata.name; // Export the OpenSIPS service endpoint export const openSipsServiceEndpoint = openSipsChart .getResource("v1/Service", "opensips", "opensips-service") // Adjust the arguments to match the actual service name and kind .metadata .apply(meta => `http://${meta.name}.${meta.namespace}.svc.cluster.local`);
In the above program:
- We first import the necessary Kubernetes package from Pulumi.
- We create a Kubernetes namespace where the OpenSIPS Helm chart will be deployed. Namespaces help you organize your Kubernetes resources.
- We then declare a
Chart
resource, namedopensips
, representing the deployment of the OpenSIPS Helm chart.chart
specifies the name of the chart to deploy.version
is the chart version that you want to deploy. You need to replace1.0.0
with the actual chart version you intend to use.namespace
is the namespace into which you want to deploy the chart. We use the name of the namespace we created earlier.fetchOpts.repo
is the URL of the Helm chart repository that contains the OpenSIPS Helm chart. Replacehttp://myhelmrepo.com/
with the actual URL.
- We include a
dependsOn
option to ensure that the namespace is created before the Helm chart is deployed. - We export the
opensipsNamespace
, which allows you to see the namespace's name after deployment through Pulumi's CLI. - We export the
openSipsServiceEndpoint
, which tries to create a well-formed URL for accessing the OpenSIPS service inside the cluster. This assumes a Service resource namedopensips-service
is created as part of the Helm chart.
To deploy this with Pulumi, save the program to a file, such as
index.ts
, in your Pulumi project directory. Then, run the following commands to login to Pulumi, select the appropriate stack (an isolated environment where your project's resources are deployed), and apply the changes:pulumi login pulumi stack select my-stack-name # Replace with your stack name or create a new one pulumi up
Pulumi will show you a preview of the resources that will be created and ask for confirmation before proceeding with the deployment. If everything looks good, confirm the deployment, and Pulumi will deploy the OpenSIPS Helm chart to your Kubernetes cluster.
Remember, this program assumes that you have a Kubernetes cluster already set up and that
kubectl
is configured to connect to it. Additionally, ensure that the version number and repository URL match the details of the OpenSIPS Helm chart you wish to deploy.
