Live streaming demo

Demo project to experiment with live video streaming, nodejs and kubernetes.

The app uses MPEG-DASH technique to stream live video content.

The live streaming is simulated by looping a sample video.

You can try the application at http://35.230.152.32. Login with email [email protected] and password pass.

Build and push Docker images

To build the Docker images locally you need to install Docker.

Then run

sh build.sh

This will build all the app components images and push them to the configured image registry.

Note: you need to be logged in your Docker registry service to push the images, see docker login.

Deploy the app on Google Cloud Platform

Install and configure the Google Cloud SDK.

The app will be deployed on Google Cloud using kubernetes.

Create the project

gcloud projects create live-streaming-demo

Create and activate the local configuration for the project

gcloud config configurations create live-streaming-demo --activate --account <YOUR_GMAIL_EMAIL> --project live-streaming-demo

Optionally, setup the region/zone where you want to deploy the kubernetes cluster (see available regions/zones)

gcloud config set compute/zone <YOUR_ZONE>

Enable container service (you need to enable the billing for the project, check here)

gcloud services enable container

Create the kubernetes cluster

gcloud container clusters create live-streaming-demo --node-version latest --num-nodes 1

Fetch credentials for the cluster

gcloud container clusters get-credentials live-streaming-demo

Deploy the application

kubectl create -f ./deployment

Check if all the services are up and running

$ kubectl get services

live-streaming-demo-redis      ClusterIP      10.63.255.224   <none>           6379/TCP       50m

Copy and paste the EXTERNAL_IP of the live-streaming-demo-frontend in your browser to use the app.

Run the app locally

To run the application locally you need to install Minikube.

Start the minikube cluster

minikube start

Use minikube cluster context

kubectl config use-context minikube

Deploy the application

kubectl create -f ./deployment

Open the app in your browser

• On MacOS: open $(minikube service live-streaming-demo-frontend --url)
• On linux: xdg-open $(minikube service live-streaming-demo-frontend --url)
