space-invaders

This is a demo app that uses a simple Angular JS website. It can be deployed anywhere (virtual machines, App Engine, Cloud Run, Kubernetes, etc. )

We use this application in a number of training classes to demo things like Cloud Deployments and CI/CD pipelines.

Docker

The Dockerfile is configured to copy the App into a Docker Image with Nginx installed.

To build the image:

docker build -t [your-docker-id]/space-invaders:v1.0 .

To run the image on port 8080:

docker run -p 8080:80 [your-docker-id]/space-invaders:v1.0

App Engine

See the app.yaml file for App Engine configuration

To create the App Engine application:

gcloud app create --region=us-central

Then to deploy the App Engine App:

gcloud app deploy --version=one --quiet

Kubernetes

Kubernetes Configuration files are located in the kubernetes-configs folder

To deploy version one to a Kubernetes cluster:

kubectl apply -f ./kubernetes-configs/kubernetes-deployment.yaml
kubectl apply -f ./kubernetes-configs/kubernetes-service.yaml
kubectl apply -f ./kubernetes-configs/kubernetes-autoscaler.yaml

The file kubernetes-configs/kubernetes-deployment-v2.yaml can be used to demo Blue/Green deployments.

Apache Web Server

To run on Apache Web Server run the following startup script on a Debian Linux VM

#! /bin/bash

apt update
apt install -y git apache2
cd /var/www/html
rm index.html -f
git init
git pull https://github.com/drehnstrom/space-invaders

CI/CD Pipeline

There is a GitHub action setup that deploys the app to both App Engine and Cloud Run when a Push or Pull Request is made to the Master Branch. See the following file: https://github.com/drehnstrom/space-invaders/blob/master/.github/workflows/main.yml
