Stateless application using a deployment

This example lives in the pulumi/examples repository. Check out just this directory to use it:

$ git clone --filter=blob:none --sparse https://github.com/pulumi/examples pulumi-examples
$ git -C pulumi-examples sparse-checkout set kubernetes-ts-nginx
$ cd pulumi-examples/kubernetes-ts-nginx

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

There is an interactive Tutorial available for this example. If this is your first time using Pulumi for Kubernetes, we recommend starting there.

Prerequisites#

1. Install Pulumi
2. Configure Kubernetes
3. Install Node.js

Deploying the example#

1. Create a new stack:

   pulumi stack init dev

2. Install dependencies:

   npm install

3. Deploy the stack:

   pulumi up

   Updating stack 'k8s-nginx-dev'
   Performing changes:
   
        Type                           Name                     Status      Info
    +   pulumi:pulumi:Stack            k8s-nginx-k8s-nginx-dev  created
    +   └─ kubernetes:apps:Deployment  nginx                    created
   
   info: 2 changes performed:
       + 2 resources created
   Update duration: 18.291517072s

   This deployment is now running, and 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 two instances, but you can easily change that to five, by running the pulumi config command followed by another pulumi up:

pulumi config set replicas 5
pulumi up

Updating stack 'k8s-nginx-dev'
Performing changes:

     Type                           Name                     Status      Info
 *   pulumi:pulumi:Stack            k8s-nginx-k8s-nginx-dev  done
 ~   └─ kubernetes:apps:Deployment  nginx                    updated     changes: ~ spec

info: 1 change performed:
    ~ 1 resource updated
      1 resource unchanged
Update duration: 4.324849549s

Cleaning up#

Once you’re finished experimenting, you can destroy your stack and remove it to avoid incurring any additional cost:

pulumi destroy
pulumi stack rm
