Intel CS for WebRTC Deployment on Kubernetes

Container images, configurations and Helm charts for installing Intel CS for WebRTC on Kubernetes.

Docker images

Images to run a Intel CS for WebRTC MCU for multi-party conferences.

Building images

Universal MCU components image

You will create universal MCU components image which can be used as any MCU components like nuve, cluster-manager, portal, so on.

First, download the latest release from here.

Unzip it and copy the MCU package file to docker/conference folder.

cp CS_WebRTC_Conference_Server_MCU.v<Version>.tgz <Project Root>/docker/conference

To build the image, docker-compose command can be used:

cd docker/conference
docker-compose build

It will create intelcs image which is universal MCU components image.

coturn image

This project uses the coturn as a turn server.

To build the image, the create_image.sh-script in the docker/coturn folder can be used:

cd docker/coturn
./create_image.sh

It will create coturn image.

Peer server image

You can also create the peer server image if you want to deploy it.

copy the peer server release package file to docker/peer folder.

cp CS_WebRTC_Conference_Server_Peer.v<Version>.tgz <Project Root>/docker/peer

To build the image, docker-compose command can be used:

cd docker/peer
docker-compose build

It will create intelcspeer image.

Publishing images

Push the intelcs, coturn and intelcspeer(option) to the configured registry.

Running images in Docker

You can run MCU and peer servers on Docker.

Runnning MCU in Docker

Run the MongoDB and the RabbitMQ

cd docker/conference
docker-compose up -d mongo rabbit

Run the other components after the MongoDB and the RabbitMQ initialized

docker-compose up -d

Print log to find the sample service ID and service Key.

docker-compose logs nuve | grep sample

It will display something like this.

nuve_1             | sampleServiceId: <Service ID>
nuve_1             | sampleServiceKey: <Service Key>

Edit the Docker environment file.

cp app.env.sample app.env
vi app.env

Replace _service_ID_ with <Service ID> and _service_KEY_ with <Service Key>.

Restart the sample application.

docker-compose restart app

_Note: You only need to restart app first time since the service ID and service Key are stored in DB and won't change.

To check the sample MCU application, access to following URL on your browser.

http://localhost:3001

Running peer server in Docker

cd docker/peer
docker-compose up -d

Helm Charts

These Helm charts can be used to install a Intel CS for WebRTC cluster consisting of a MCU and a peer server on a Kubernetes cluster.

The following tutorial will show how you deploy a Intel CS for WebRTC on a Kubernetes cluster which was created by kops on AWS.

Prerequisites

• Released nginx-ingress with default-ssl-certificate
• Released external-dns

Create Instance Groups

Create two instance groups.

• intelcs
• coturn

The following ports should be open in the firewall for coturn.

• 3478 TCP & UDP
• 49152 - 65535 UDP

Create an additional security group to open those ports.

Add it to the coturn instance group by setting additionalSecurityGroups.

apiVersion: kops/v1alpha2
kind: InstanceGroup
metadata:
  labels:
    kops.k8s.io/cluster: my-beloved-cluster
  name: coturn
spec:
  additionalSecurityGroups:
  - sg-xxxxxxxx
  - sg-xxxxxxxx

Deploy MongoDB, RabbitMQ and Coturn

Deploy the MongoDB, the RabbitMQ and the coturn.

cd helm
helm install ./mongo \
  -n intelcs-mongo \
  -f ../supplements/kops/intelcs-mongo.yaml
helm install stable/rabbbitmq \
  -n intelcs-rabbit \
  -f ../supplements/kops/intelcs-rabbit.yaml
helm install ./coturn \
  -n intelcs-coturn \
  -f ../supplements/kops/intelcs-coturn.yaml

Deploy Nuve

Deploy the nuve.

cd helm
helm install ./nuve \
  -n intelcs-nuve \
  -f ../supplements/kops/intelcs-nuve.yaml

Configure Custom Values

Get Service ID and Service Key

kubectl logs -l app=nuve -c nuve | grep sample

It will display something like this.

sampleServiceId: <Service ID>
sampleServiceKey: <Service Key>

Get public DNS of coturn node.

kubectl describe node -l kops.k8s.io/instancegroup=coturn | grep ExternalDNS

Edit Sample MCU Application Custom Values

cd supplements/kops
vi intelcs-app.yaml

Replace value of basicapp.env.SERVICE_ID in intecs-app.yaml with <Service ID>.

Replace value of basicapp.env.SERVICE_KEY in intecs-app.yaml with <Service Key>.

Replace value of basicapp.env.TURN_HOST in intecs-app.yaml with public DNS of coturn node.

Replace basicapp.example.com with your desired host name for sample MCU application URL.

Edit Management Console Custom Values

cd supplements/kops
vi intelcs-management-console.yaml

Replace icsconsole.example.com with your desired host name for Management Console URL.

Edit Portal Custom Values

cd supplements/kops
vi intelcs-portal.yaml

Replace portal.example.com with your desired host name for portal.

Edit Peer Server Custom Values

cd supplements/kops
vi intelcs-peer.yaml

Replace peer.example.com with your desired host name for peer server.

Deploy Other Components

cd helm
helm install ./cluster_manager \
  -n intelcs-cluster-manager \
  -f ../supplements/kops/intelcs-cluster-manager.yaml
helm install ./portal \
  -n intelcs-portal \
