A version of the Kubernetes Stateless Application Deployment example that uses Pulumi. This example deploys a replicated Nginx server to a Kubernetes cluster, using Scala and no YAML.

This example is based on a Pulumi Tutorial available here.

Follow the instructions to get started with Pulumi & Kubernetes.

Note: some values in this example will be different from run to run. These values are indicated with ***.

1. Create a new stack, which is an isolated deployment target for this example:

   pulumi stack init kubernetes-nginx-dev

2. Run pulumi up to preview and deploy changes. After the preview is shown you will be prompted if you want to continue or not.

   pulumi config set replicas 2
   pulumi up

   After a couple of minutes, your deployment will be ready, Pulumi will wait for it to become ready. You can run commands like kubectl get pods to see the application's resources.

   The stack's replica count is configurable. By default, it will scale up to three instances, but we can easily change that to five, by running the pulumi config command followed by another pulumi up:

   pulumi config set replicas 5
   pulumi up

3. From there, feel free to experiment. Simply making edits and running pulumi up will incrementally update your infrastructure.

4. To clean up resources, destroy your stack and remove it:

   pulumi destroy

   pulumi stack rm kubernetes-nginx-dev
