The original work is Laremere/space-agon.

Space Agon

Space Agon is a integrated demo of Agones and Open Match.

Before Trying

Be aware of billing charges for running the cluster.

Space Agon is intended to run on Google Kubernetes Engine (GKE) and has been tested with the configured cluster size. Leaving the cluster running may incur your cost. You need to be responsible for the cost. (See pricings of GKE, Cloud Build and Artifact Registry.)

Prerequisites

Create your Google Cloud Project.

Install tools in your dev environment:

• gcloud
• docker
• kubectl
• helm
• envsubst (Optional)
• skaffold (Optional)
• minikube (Optional)
• hyperkit (Optional)

Google Cloud Shell has all tools you need.

Create the Resources and Install Gaming OSS

Deploy them to Google Cloud

# Set Your Project ID before you run
export PROJECT_ID=<your project ID>

export LOCATION=us-central1
export ZONE=$LOCATION-a

export REPOSITORY=space-agon

gcloud services enable artifactregistry.googleapis.com \
                        container.googleapis.com

gcloud config set project $PROJECT_ID

gcloud config set compute/zone $ZONE

# Create cluster (using default network)
# Set NETWORK=<your network>, if you want to select the network
make gcloud-test-cluster

# Create Artifact Registry Repository
gcloud artifacts repositories create $REPOSITORY \
    --repository-format=docker \
    --location=$LOCATION 

# Assign roles to default service account
gcloud projects add-iam-policy-binding $PROJECT_ID \
    --member serviceAccount:$(gcloud iam service-accounts list \
    --filter="displayName:Compute Engine default service account" \
    --format="value(email)") \
    --role roles/artifactregistry.reader

# Login Artifact Registry
gcloud auth configure-docker $LOCATION-docker.pkg.dev

# Add Helm Repositories 
make helm-repo-add

# Install Agones
make agones-install

# Install Open Match
make openmatch-install

Deploy them to local k8s cluster by minikube

# Start minikube
# ref: https://minikube.sigs.k8s.io/docs/commands/start/
# Or you can other dirvers
minikube start --cpus="2" --memory="4096" --kubernetes-version=v1.24.16 --driver=hyperkit

# Add Helm Repositories 
make helm-repo-add

# Install minimized Agones
make agones-install-local

# Install minimized Open Match
make openmatch-install-local

Deploy applications

Deploy to Google Cloud

Make sure you installed docker to build and push images

# Build Space Agon images
make build

# Deploy Space Agon
make install

Deploy to local k8s cluster by minikube

# Build Space Agon images for minikube cluster
make build-local

# Deploy Space Agon for minikube cluster
make install

View and Play

Get External IP from:

kubectl get service frontend

When you run Space Agon in minikube, you should followings in another terminal:

minikube tunnel

Open http://<external ip>/ in your favorite web browser. You can use "Find Game" to start searching for a match.

Repeat in a second web browser window to create a second player, the players will be connected and can play each other.

Access GameServer

View Running Game Servers:

kubectl get gameserver

Then use the connect to server option with the value <ip>:<port>.

Changing the parameters

If you'd like to modify your parameters of your deployments, you can change in install/helm/space-agon/values.yaml or use --set parameters directly.

Space Agon uses Helm to install the applications.

# values.yaml
frontend:
  name: frontend
  replicas: 2
  containerPort: 8080
  servicePort: 80
  serviceType: LoadBalancer 
  image: 
    repository: YOUR_REPO_NAME_HERE
    tag: YOUR_TAG_HERE
...

Clean Up

Delete the deployment

# Uninstall Space Agon Applications
make uninstall

Uninstall Agones

make agones-uninstall

Uninstall Open-Match

make openmatch-uninstall

(Optional) Remove Helm Repositories

You can remove Helm repositories by the command, if you do not need.

make helm-repo-remove

Delete your Google Cloud Project

# Delete project
gcloud projects delete $PROJECT_ID

(Optional) Develop Applications with Skaffold

In case testing your original match making logics, skaffold can help you debug your applications.

Setup

1. Create a Space Agon cluster.
2. Install skaffold

After running make build or make build-local, you're ready to run skaffold commands.

Develop

Once you create a skaffold.yaml, you can run skaffold commands.

# You need envsubst for setting up a skaffold file
# Setup skaffold 

make skaffold-setup

# For local development

make skaffold-setup-local

# Build Space Agon images with Cloud Build
skaffold build 

# Run Applicaitons in the local Space Agon cluster for debugging.
skaffold dev

# Use cloud profile in case of GKE (Run `make build` first)
skaffold dev -p cloud

# Check your deployed yaml file
skaffold render

Modifying applications or helm values during skaffold dev triggers Build and Deploy again automatically.
For more commands and details, visit skaffold.

Test your Cluster

When you would like to test the application, follow the steps below.

Google Cloud

1. Create a Space Agon k8s cluster.
2. Run below commands for integration test.

# Run you Space Agon applications
# Optiionally, you can use `skaffold dev`
make install

# Open another terminal and
# Run Test command
make integration-test

minikube

1. Create a Space Agon k8s cluster on minikube.
2. Run below commands for integration test.

# Connect to service in minikube
minikube tunnel

# Open another terminal and
# Run Test command
make integration-test
