Blue/Green Kubernetes Deployment Stack

This example project deploys the pulumi-kubernetes-operator, and a Pulumi program as a Stack CustomResource once the operator is up and running.

We'll walk through deploying a Blue/Green Kubernetes App Deployment in the same cluster as the operator.

We'll use the Stack CustomResource to capture the Pulumi project's settings, and the operator will drive the Pulumi updates for us, all natively in Kubernetes.

Overview

The Stack CustomResource encapsulates a Pulumi project that creates an Kubernetes App Deployment from an existing Git repo, and checks out a specific commit SHA of the repo to deploy.

The App is an example of a Blue/Green Deployment in Kubernetes. This deploys an initial version of the app to the Internet, and then deploys an updated version beside the initial version. Once ready, we'll switch the traffic from the initial version to the new version.

Requirements

Get Started with Pulumi and Kubernetes.
You can use an existing Kubernetes cluster, or create a new managed Kubernetes cluster.

NOTE: This example uses a Kubernetes Load Balancer Service. Please make sure your Kubernetes provider can provision load balancers. Specifically, this will not work on Minikube or Kind.

App Deployment

The application is a stateless HTTP server that returns request information and the version of the Pod serving the response.

The commit history of the App Deployment git repo reflects the sequential changes one would make when building out a rolling deployment of a live service.

Here is commit history of the repo, where the bottommost commit is the initial commit, followed by two changes.

For the sake of this demo we'll "skip ahead" to start with the "Add Deployment V2" commit.

At the V2 commit, we'll have deployed the following resources in Kubernetes.

V1 of the Deployment, with a public Service Load Balancer attached to it to serve traffic.
V2 of the Deployment that is not serving traffic since the Service still selects the V1 Pods, and we have not yet switched traffic between deployments.

Initialize the Pulumi Project

Clone the repo:

git clone https://github.com/pulumi/pulumi-kubernetes-operator
cd examples/blue-green

Install the dependencies.
```
npm install
```
Create a new Pulumi stack named dev.
```
pulumi stack init dev
```
Set the Pulumi configuration variables for the project.

In this step, we'll configure the Pulumi settings stackProjectRepo and stackCommit to reflect that we want to use the app's Git repo, and a given commit.

You'll first need to grab a Pulumi API access token from the Pulumi Service.
- Visit the Pulumi Service.
- In your profile, click 'Settings' -> 'Access Tokens'.
- Generate a new access token.
Now configure the Stack settings by copy/pasting the following, and replacing the token with your newly created one.
```
pulumi config set --secret pulumiAccessToken <YOUR_PULUMI_API_TOKEN>
pulumi config set stackProjectRepo https://github.com/metral/pulumi-blue-green
pulumi config set stackCommit b19759220f25476605620fdfffeface39a630246
pulumi config set stackName <YOUR_ORG>/pulumi-blue-green/dev
```
Make sure to use your Pulumi organization or user name instead of <YOUR_ORG> above.

Run the Update

The update will deploy the operator to Kubernetes, along with the Stack for the App.

pulumi up

Once the update is complete, verify the operator Pod is up and running:

$ kubectl get pods -o wide -l name=pulumi-kubernetes-operator

NAME                                           READY   STATUS    RESTARTS   AGE
pulumi-kubernetes-operator-6c4d99b4b6-wqbxg    1/1     Running   0          2m39s

Verify the Operator and Stack are running

In another terminal, you can tail the logs of the operator to see it in action.

kubectl logs -l name=pulumi-kubernetes-operator -f

You should see output similar to the details below.

Similarly, we can probe Kubernetes for the status of the Stack.

In the details, stack.status will show the following information when it is made available.

A permalink URL for the Stack in the Pulumi Service when available.
The last commit state of the Pulumi program that has been successfully deployed, and
Any Pulumi stack outputs that exist.

Using curl we can validate that the App Deployment was deployed to the cluster by the operator by checking its endpoint.

curl http://34.83.25.150:80/version

{"id":1,"content":"current"}

Generate Traffic

To validate that we are making a clean cut-over from V1 to V2, we'll generate consistent traffic to the endpoint.

while true; do curl http://34.83.25.150:80/version ; echo; sleep 1; done

{"id":1,"content":"current"}
{"id":1,"content":"current"}
{"id":1,"content":"current"}
{"id":1,"content":"current"}
...

Switch Traffic from V1 to V2

With V1 deployed and validated, and the V2 deployment up and ready, now it's time to switch over traffic of the Service from V1 to V2.

We'll make the changes by simply updating the project's stackCommit config for the Stack CustomResource, and running another Pulumi update.

pulumi config set stackCommit f4bf2f7b54ec441d5af374933cca4ef09f2bce24
pulumi up

After a few seconds you should start seeing the generated traffic returning the new version in a clean cut-over with no dropped packets.

Wrap-Up

We used the pulumi-kubernetes-operator to drive Pulumi updates by representing the program Stack natively in Kubernetes using the Stack CustomResource.

The demo app showcased how to perform a Kubernetes Blue/Green Deployment, and by driving towards the state of a given Git repo's commit, the operator is able to reach a desired state in the lifecycle of your applications.

Given that the desired state for the operator is based on an explicit commit SHA being checked out from the repo and deployed through Pulumi, we are able to see how we can leverage this approach for CI/CD of your Pulumi programs.

Though we manually changed commits using the Pulumi config system, abstracting program Stacks in this fashion showcases how Pulumi can be used to manage Stacks natively in Kubernetes, opening up opportunities for further integration and automation pipelines.

The operator is also able to track Git branches and automatically roll out changes as commits get pushed to the branch, so that you don't have to manually update commits.

Clean Up

Run the following command to tear down the resources that are part of our stack.

Run pulumi destroy to tear down all resources. You'll be prompted to make sure you really want to delete these resources.
```
pulumi destroy
```
To delete the stack, run the following command.
```
pulumi stack rm
```
Note: This command deletes all deployment history from the Pulumi Console and cannot be undone.
