Quinoa WindTurbine Racer Demo

This project uses Quarkus, the Supersonic Subatomic Java Framework.

Running the application in dev mode

Install first:

  • JDK 17
  • Maven
  • Quarkus CLI

You can run your application in dev mode that enables live coding using:

quarkus dev

Deploy on Cluster with admin rights

Setup

To run this demo you need OpenShift >=4.10 with cluster-admin privileges.

Quay.io

Account

Create an account on Quay.io if you do not already have one.

Repositories

Create two repositories with public access (pull), you will use credentials in the next step to push container images.

From right-side menu, click Create New Repository

Create a new repository:

  • quinoa-wind-turbine

Flag it as Public Repository and click Create Public Repository

Create secret

  • Login to quay.io in the web user interface and click on your username in the top right corner.
  • Select account settings.
  • Click the blue hyperlink Generate Encrypted Password.
  • Re-enter your password when prompted.
  • Copy the password

Create repo

Setup OpenShift

Login to OpenShift Web Console to install prerequisites.

First, create a project for the demo:

oc new-project demo --description='wind-turbine-race'

You can choose a different name, but then you have to update argo/wind-turbine-app.yaml before you deploy the app (see below in the Flow section).

Install Operators

OpenShift Pipelines

OpenShift Pipelines is provided as an add-on on top of OpenShift that can be installed via an operator available in the OpenShift OperatorHub. Follow these instructions in order to install OpenShift Pipelines on OpenShift via the OperatorHub.

From the left-side menu under Administrator perspective, go to Operators-> OperatorHub. In the search box, search for pipelines, then click to OpenShift Pipelines Operator:

OperatorHub

From the description view, click Install to review all installation settings.

Install Pipelines

Ensure Update Channel is set to stable , and click Install to start installing the Operator.

Install Operator

After few seconds, the installation should be completed with success and you can verify it looking at Status column, check if the status is Succeeded.

Pipelines Installed

OpenShift GitOps

Log into OpenShift Web Console as a cluster admin and navigate to the Administrator perspective and then Operators → OperatorHub.

In the OperatorHub, search for OpenShift GitOps and follow the operator install flow to install it.

Add permission to Argo CD service account

IMPORTANT Give permission to the Argo CD service account to control the cluster:

oc adm policy add-cluster-role-to-user cluster-admin -z openshift-gitops-argocd-application-controller -n openshift-gitops

Once OpenShift GitOps is installed, an instance of Argo CD is automatically installed on the cluster in the openshift-gitops namespace and link to this instance is added to the application launcher in OpenShift Web Console.

Application Launcher

Log into Argo CD dashboard

Click on Argo CD from the OpenShift Web Console application launcher and then log into your OpenShift credentials using the OpenShift Auth option.

Argo CD

Argo CD

AMQ Streams

Install AMQ Streams from OperatorHub and create a KafkaCluster named my-cluster

Infinispan

  1. Create an infinispan cluster from the Web Console using the "Infinispan Helm chart"
  2. Name it infinispan

Flow

Create a Secret with your Quay.io credentials with the encrypted password you copied before:

oc create secret docker-registry quay-secret --docker-server=quay.io --docker-username=<QUAY_USERNAME> --docker-password=<ENCRYPTED_PASSWORD>

Create a Secret with your GitHub Personal Access Token

apiVersion: v1
kind: Secret
metadata:
  name: git-user-pass
  annotations:
    tekton.dev/git-0: https://github.com
type: kubernetes.io/basic-auth
stringData:
  username: <github user>
  password: <github personal access token>

Save it to a file with your credentials and create the secret:

oc create -f git-user-pass.yaml

Link Secrets to pipeline Service Account.

NOTE: Pipelines Operator installs by default a pipeline Service Account in all projects. This service account is used to run non-privileged containers and builds across the cluster.

oc secret link pipeline quay-secret
oc secret link pipeline git-user-pass

Fork this repo

In order to enable webhooks, fork this repo

Fork and clone GitOps manifests repo

git clone https://github.com/<yourgithubuser>/quinoa-wind-turbine-manifests
cd quinoa-wind-turbine-manifests

Create Tekton pipeline manifests

Change the GitOps repo to your fork:

sed -i 's/rhdevelopers/yourquayuser/g' tekton/pipeline-cached.yaml
sed -i 's/redhat-developer-demos/yourgithubuser/g' tekton/pipeline-cached.yaml
oc apply -f tekton/app-source-pvc.yaml 
oc apply -f tekton/build-cache-pvc.yaml 
oc apply -f tekton/git-update-deployment.yaml
oc apply -f tekton/maven-task-cached.yaml 
oc apply -f tekton/pipeline-cached.yaml 
oc apply -f tekton/triggerbinding.yaml
oc apply -f tekton/triggertemplate-cached.yaml
oc apply -f tekton/eventlistener.yaml
oc apply -f tekton/el-route.yaml

Update all references to quay.io with your repos for quinoa-wind-turbine references:

sed -i 's/rhdevelopers/yourquayuser/g' k8s/deployment.yaml
sed -i 's/redhat-developer-demos/yourgithubuser/g' argo/wind-turbine-app.yaml
git add .
git commit  -m "update reference to quay and github"
git push

Create Argo CD Application to deploy the game

oc apply -f argo/wind-turbine-app.yaml

Start the Pipeline or edit Config.js to switch to V2:

export const ENABLE_SHAKING = true;

SSL (if the cluster doesn't have a signed certificate):

Let'encrypt (if the cluster doesn't have a signed certificate):

oc apply -fhttps://raw.githubusercontent.com/tnozicka/openshift-acme/master/deploy/single-namespace/{role,serviceaccount,issuer-letsencrypt-live,deployment}.yaml
oc create rolebinding openshift-acme --role=openshift-acme --serviceaccount="$( oc project -q ):openshift-acme" --dry-run -o yaml | oc apply -f -

If the cluster has a signed certificate, create a route with an "edge" tls termination.

Install Kafka

  • From the operator hub, install Strimzi operator.
  • Create a Kafka instance named my-cluster

Infinispan server

  1. Create an infinispan cluster in the console using the "Infinispan Helm chart"
  2. Name it infinispan
