Rock, Paper, Scissors, Lizard, Spock is the geek version of the classic Rock, Paper, Scissors game.
Rock, Paper, Scissors, Lizard, Spock - Sample Application
Rock, Paper, Scissors, Lizard, Spock is the geek version of the classic Rock, Paper, Scissors game. Rock, Paper, Scissors, Lizard, Spock is created by Sam Kass and Karen Bryla.
The Rock, Paper, Scissors, Lizard, Spock - Sample Application shows a multilanguage application built with Visual Studio and Visual Studio Code, deployed with GitHub Actions and running on Azure Kubernetes Service (AKS). The sample application also uses Machine Learning and Azure Cognitive Services (Custom Vision API). Languages used in this application include .NET, Node.js, Python, Java, and PHP.

This a multilanguage application running on AKS with AI embedded. There are 5 bots (.NET, NodeJS, Python, Java and PHP) the user can select a language as the opponent and both, the user and the bot will have to select an object to play. The Game Manager which is a .NET API decides who wins based on the logic of the game. If the user is authenticated using Twitter the bots will call a predictor AI Model (Python Azure Function), this model learns from the selections of the objects that the user have done based on the history (stored in a Cosmos DB) to try to predict their next move. If the user is not authenticated the bots will select a random object. There is also a TensorFlow model created with Custom Vision to allow the user to play with their hands by using the webcam.
If you want to deploy this solution in Azure:
- You will need and Azure Subscription in order to deploy this.
- Azure CLI.
- Download and install helm.
New to Microsoft Azure?
You will need an Azure subscription to work with this demo code. You can:
- Open an account for free Azure subscription. You get credits that can be used to try out paid Azure services. Even after the credits are used up, you can keep the account and use free Azure services and features, such as the Web Apps feature in Azure App Service.
- Activate Visual Studio subscriber benefits. Your Visual Studio subscription gives you credits every month that you can use for paid Azure services.
- Create an Azure Student Account and get free credit when you create your account.
Learn more about it with Microsoft Learn - Introduction to Azure.
You can either go through all steps and customizing its configuration or run one single command.
Execute the script located in Deploy folder with the following parameters:
.\Deploy-Unified.ps1 -resourceGroup <resource-group-name> -location <location> -clientId <service-principal-id> -password <service-principal-password> -subscription <subscription-id>
resourceGroup: The name of your resource group where all infrastructure will be created
location: Select where you want to create your resource group, for example:
clientId: Id of the service principal used to create the AKS
password: Password of the service principal
subscription: Id of your subscription where you are going to deploy your resource group
If service principal credentials are not passed a new one will be created.
To run RPSLS you need to create the Azure infrastructure. There are two ways to do it. Using Azure portal or using a Powershell script.
An ARM template is provided so you can create the whole infrastructure required for RPSLS
servicePrincipalId: Id of the service principal used to create the AKS
servicePrincipalSecret: Password of the service principal
aksVersion: AKS version to use.
The deployment could take more than 10 minutes, and once finished all needed resources will be created.
You can use the CLI to deploy the ARM script. Open a Powershell window from the
/Deploy folder and run the
Deploy-Arm-Azure.ps1 with following parameters:
-resourceGroup: Name of the resource group
-location: Location of the resource group
Required if resourceGroup does not exist
-clientId: Id of the service principal used to create the AKS
-password: Password of the service principal
If service principal credentials are not passed a new one will be created.
Once script finishes, everything is installed. If a service principal has been created, the script will output the service principal details - please, take note of the appId and password properties for use them in the AKS deployment
Pre-requisites for this deployment are to have:
- The AKS and all related resources deployed in Azure
- A terminal with Powershell environment
- Azure CLI 2.0 installed.
- Azure Functions Core Tools installed (required only to deploy Predictor).
- Kubectl installed with the last version (v1.16.0 at this moment).
- Helm 3 installed with 3.0 or superior version (v3.0.0 at this moment).
- Docker installed
A Service Principal is needed for creating the AKS. If you use the CLI for create the resources. You need the client id and password of a Service Principal to install RPSLS.
In case you use Azure Portal for the resources' creation, you can also reuse a SP or create manually a new one for passing the credentials to the template.
Connecting kubectl to AKS
From the terminal type:
az loginand follow instructions to log into your Azure.
- If you have more than one subscription type
az account list -o tableto list all your Azure subscriptions. Then type
az account set --subscription <subscription-id>to select your subscription
az aks get-credentials -n <your-aks-name> -g <resource-group-name>to download the configuration files that
kubectlneeds to connect to your AKS.
At this point if you type
kubectl config current-context the name of your AKS cluster should be displayed. That means that
kubectl is ready to use your AKS
The KeyVault support is implemented through FlexVol. To install Flex Volume in the AKS, type the following:
Publish Python Azure Function
To publish the Azure Function you can execute the next command of the Azure Functions Core Tools from the folder
func azure functionapp publish <funcapp-name> --no-build
The value for
funcapp-name must be the name of the Function App created in your Azure Resource Group.
Before deploying services using Helm, you need to setup the configuration. We refer to the configuration file with the name of gvalues file. This file contains all secrets so beware to not commit in your repo accidentally.
A template of this file is in
powershell/gvalues.template. The deployment scripts use this file by default, but do not rely on editing this file. Instead create a copy of it a folder outside the repository and use the
-valuesFile parameter of the deployment script.
Note: The folder
/Deploy/helm/__values/is added to
.gitignore, so you can keep all your configuration files in it, to avoid accidental pushes.
Please refer to the comments of the file for its usage.
Auto generating the configuration file
Generating a valid gvalues file can be a bit harder, so there is a Powershell script that can do all work by you. This script assumes that all resources are deployed in the same resource group, and this resource group contains only the RPSLS resources. Also assumes the Azure resources have been created using the tools provided in this repo.
Note The Generate-Config.ps1 uses the application-insights CLI extension to find the application insights id. Install it with
az extension add --name application-insights
Note The configuration script requires the Azure function key so internal aks services can call it. So before executing the Generate-Config.ps1 make sure that the function is already published and the function key exists.
To auto-generate your gvalues file just go to
/Deploy/powershell folder and from a Powershell window, type the following:
.\Generate-Config.ps1 -resourceGroup <your-resource-group> -outputFile ..\helm\__values\<name-of-your-file>
Generate-Config.ps1 script accepts so many parameters. Here you can find a list of them all.
The script checks that all needed resources exists in the resource group. If some resource is missing or there is an unexpected resource, the script exits.
Build & deploy images to ACR
You can manually use docker-compose to build and push the images to the ACR. If using compose you can set following environment variables:
TAG: Will contain the generated docker images tag
REGISTRY: Registry to use. This variable should be set to the login server of the ACR
Once set, you can use
docker-compose build and
docker-compose push to build and push the images.
Additionally there is a Powershell script in the
Deploy folder, named
Build-Push.ps1. You can use this script for building and pushing ALL images to ACR. Parameters of this script are:
resourceGroup: Resource group where ACR is. Required.
acrName: ACR name (not login server). Required.
dockerTag: Tag to use for generated images (defaults to
$true(default value) docker images will be built using
$true(default value) docker images will be push to ACR using
This script uses
az CLI to get ACR information, and then uses
docker-compose to build and push the images to ACR.
To build and push images tagged with v1 to a ACR named my-acr in resource group named my-rg, execute the following command inside
.\Build-Push.ps1 -resourceGroup my-rg -dockerTag v1 -acrName my-acr
To just push the images (without building them before):
.\Build-Push.ps1 -resourceGroup my-rg -dockerTag v1 -acrName my-acr -dockerBuild $false
You need to use Powershell and run
./Deploy-Images-Aks.ps1. A typical call is:
.\Deploy-Images-Aks.ps1 -resourceGroup $resourceGroup -aksName $myAks -acrName $myAcr -valuesFile $myValuesFilePath -tag v1
Note: Read the documentation of this script for a list of all parameters.
This script will install all services using Helm and your custom configuration from the configuration file set by
charts allow for a selective installation of charts. Is a list of comma-separated values that mandates the services to deploy in the AKS. Values are:
We distributed some swag after the keynote session at Ignite (t-shirts, stickers and pins) but we had a limited amount so it made sense to open up the logo for swag.
