Video Conferencing with Jitsi on K8s

conferencing video

Hello, are you as excited as I am? Well, you should be because, in this article, I will explain the steps to build a video conferencing Jitsi app with K8s. Jitsi is an open-source video conferencing app that uses webrtc technology. It is similar to video conferencing on Zoom, Skype, and Google Meet apps. Moreover, with Jitsi, you can be conferencing in a room with multiple people from any device!

Benefits of Video Conferencing with Jitsi on K8s:

You can install Jitsi on your own server and activate transcription, recording, share screen, etc. You can select conferencing for E2E and enable field password to activate end-to-end encryption.

In this article, you will learn to build a video conferencing app with Jitsi on Kubernetes (K8s) baremetal. In addition, I aim to use baremetal to install alsa-loopback on Ubuntu 20.04 and create a video conferencing recording with Jibri on Jitsi run appropriately. Moreover, I also want to help you build a video conferencing app with Jitsi on K8s. Note that you can use any other version of Linux too. In addition, if you don't need the recording Jibri feature-- you can manage Kubernetes from a cloud provider.

In this section, you will learn to set up Kubernetes in Ubuntu 20.04, install Nginx Ingress, load balancer, and set up Jitsi on Kubernetes (K8s). The requirements are listed below:

  • Access to Ubuntu 20.04 for install Kubernetes with root access. However, you can also use any suitable OS version. In this section, I used Digital Ocean for a server. I use 3 servers to deploy Kubernetes.
  • Kubectl.
  • A domain name to access Jitsi public or private url.

Setting Nodes Master on Ubuntu 20.04

In this step, you will learn to build nodes and master Kubernetes. So, I have used Ubuntu 20.04 to install Kubernetes. But you can use any other version as well. After selecting your OS, login with ssh to your server. In this section, my hostname for the master is Ubuntu-k8s-sgp. Okay, let's install this package for adding the repo:

[email protected]:~# apt update && apt install curl apt-transport-https -y

Then, add GPG and key Kubernetes to Ubuntu 20.04 system.

[email protected]:~# curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
[email protected]:~# echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

Finally, perform a system update to collect the package list from the Kubernetes repository and install package.

[email protected]:~# apt update && apt -y install vim git curl wget kubelet kubeadm kubectl -y
[email protected]:~# sudo apt-mark hold kubelet kubeadm kubectl

After that, confirm the version of Kubernetes tools.

[email protected]:~# kubectl version
[email protected]:~# kubeadm version

Then, check the swap, and turn it off.

[email protected]:~# sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
[email protected]:~# swapoff -a

After turning off swap, enable kernel module.

[email protected]:~# sudo modprobe overlay
[email protected]:~# sudo modprobe br_netfilter

At this point, configure ip bridge and forward setting to sysctl.

[email protected]:~# tee /etc/sysctl.d/kubernetes.conf<<EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
EOF

Lastly, reload sysctl. And you're good to go!

sysctl --system

Configure CRI-O for Master k8s

In this article, I have used CRI-O for container runtime on Kubernetes. It is an open-source alternative to docker. The goal is to replace docker with a container engine on Kubernetes, a community-driven container engine. So, first, we need to add the repository for CRI-O.

[email protected]:~# OS="xUbuntu_20.04"
[email protected]:~# VERSION=1.23
[email protected]:~# echo "deb https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/$OS/ /" > /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list
[email protected]:~# echo "deb http://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable:/cri-o:/$VERSION/$OS/ /" > /etc/apt/sources.list.d/devel:kubic:libcontainers:stable:cri-o:$VERSION.list
[email protected]:~# curl -L https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable:cri-o:$VERSION/$OS/Release.key | apt-key add -
[email protected]:~# curl -L https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/$OS/Release.key | apt-key add -

After adding repo, update the system and install CRI-O and runc.

[email protected]:~# apt update && apt install cri-o cri-o-runc -y

Finally, CRI-O is now installed. Next, update the subnet cidr for CRIO.

sed -i 's/10.85.0.0/192.168.0.0/g' /etc/cni/net.d/100-crio-bridge.conf

After that, you need to start and enable CRI-O service.

[email protected]:~# systemctl daemon-reload
[email protected]:~# systemctl start crio
[email protected]:~# systemctl enable crio

After you have successfully installed CRI-O, you can configure Kubernetes with kubeadm init. Why? This command will help generate a token so that the Kubernetes nodes can join into the master nodes. Hence, you will be able to use multiple clusters on Kubernetes.

[email protected]:~# kubeadm init --pod-network-cidr=10.244.0.0/16

But if you already have done init with kubeadm, you need run this command to make cluster running.

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
export KUBECONFIG=/etc/kubernetes/admin.conf

Then, save the kubeadm join token command; this will be useful when cluster nodes be joined to master. nodes.

How to Setup Nodes Cluster Kubernetes for video conferencing Jitsi on K8s

To setup nodes cluster on ubuntu 20.04 you need run the steps from setting nodes master to configure CRI-O. Similarly, you can use kubeadm join to join the nodes to master. After the command kubeadm is successful, you will get this output:

video conferencing

Check that the nodes have successfully joined to the master. Here I have used 1 master and 2 nodes cluster. Se, you will see 3 nodes when you run "kubectl get nodes".

[email protected]:~# kubectl get nodes
kubectl get nodes

Moreover, we can import Kubernetes config into our local laptop. Likewise, here I have used linuxmint on my computer. To run Kubernetes on my computer, I needed to install kubectl on my laptop. So, if you want to install kubectl, you can follow these steps.

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
curl -LO "https://dl.k8s.io/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl.sha256"
echo "$(cat kubectl.sha256)  kubectl" | sha256sum --check
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

After installing kubectl, you can retrieve the Kubernetes config to the master nodes server using scp with the command "scp -r [email protected]_address:.kube ."

Kubernetes configuration

After importing the Kubernetes configuration to your laptop, check with the command "kubectl get nodes" to confirm the import was successful.

Installing Flannel for Video Conferencing Jitsi on K8s

Flannel is a virtual network layer in Kubernetes used with containers to connect, managed by CoreOS network designed for Kubernetes network interface. In addition, I used kubectl to install the flannel network.

kubectl apply -f https://github.com/coreos/flannel/raw/master/Documentation/kube-flannel.yml

Metallb for loadbalancer K8s

Metallb is a load balancer implementation for bare metal kubernetes clusters, using standard routing protocols. You can apply layer 2 for use our ip public to set public ip nodes cluster for our load balancer. Hence, I used the IP of node 2 for load balancer. Use helm charts to install metallb. After that, use helm to add metallb repository. If you don't have helm in your laptop, you can install it by following the steps here.

helm repo add metallb https://metallb.github.io/metallb

Once you have added the metallb repository with helm cherts to your local laptop, you can allocate the IP address for the load balancer in config and install metallb with helm charts.

helm upgrade --install --namespace metallb-system --create-namespace --repo https://metallb.github.io/metallb metallb metallb --values - <<EOF
configInline:
  address-pools:
  - name: default
    protocol: layer2      
    addresses:
    - ip_address_nodes/32
EOF

How to Install Nginx Ingress Controller

Nginx ingress controller is a controller provider that manage ingress so we can expose service pods on the Kubernetes. You can set domain allocation, secret certificate on Nginx Ingress. Let's install Nginx with kubectl.

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.2.0/deploy/static/provider/cloud/deploy.yaml

After you install Nginx Ingress, you can check the service using kubectl and check the ip load balancer from metallb is working properly on Nginx Ingress controller.

kubectl get svc -n ingress-nginx
video conferencing

Check load balancer public IP is running properly on Nginx Ingress using curl.

curl -v 165.232.161.25
curl nginx

Install cert-manager in K8s

Cert-manager is a service in Kubernetes that manages certificates. With cert-manager, you can create issuers to generate, renew, and manage our certificates. Here's how you can install cert-manager with helm.

helm repo add jetstack https://charts.jetstack.io
helm repo update
helm install \
  cert-manager jetstack/cert-manager \
  --namespace cert-manager \
  --create-namespace \
  --version v1.8.0 \
  --set installCRDs=true

Creating Video Conferencing Jitsi on K8s configurations

In this section, you will learn to configure video conferencing Jitsi on Kubernetes (K8s). So, the thing you need prepare is a domain to get Jitsi running and access a browser like Chrome, or Firefox. Here I have used "meet.bettercoffee.dev" domain for Jitsi public access. We need adding several environment for Jitsi configuration. Next, create a file for deployment of Jitsi web called web-deploy.yaml.

              value: "true"
            - name: XMPP_MUC_DOMAIN
              value: "muc.meet.bettercoffee.dev"

            - name: XMPP_RECORDER_DOMAIN
              value: "recorder.meet.bettercoffee.dev"

Now, create a deployment for Jitsi videobridge, the Jvb component for Jitsi meet.

create file jvb-deploy.yaml.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: jvb
  namespace: jitsi
spec:

               cpu: "1"
          imagePullPolicy: IfNotPresent
          env:
            - name: ENABLE_XMPP_WEBSOCKET
              value: "1"
            - name: ENABLE_COLIBRI_WEBSOCKET

            - name: COLIBRI_REST_ENABLED
              value: "true"
            - name: XMPP_SERVER
              value: "prosody.jitsi.svc.cluster.local"
            - name: DOCKER_HOST_ADDRESS
              value: "192.168.1.1"
            - name: XMPP_DOMAIN
              value: "meet.bettercoffee.dev"
            - name: XMPP_AUTH_DOMAIN
              value: "auth.meet.bettercoffee.dev"
            - name: XMPP_INTERNAL_MUC_DOMAIN
              value: "internal-muc.meet.bettercoffee.dev"
            - name: JVB_STUN_SERVERS
              value: "stun.l.google.com:19302,stun1.l.google.com:19302,stun2.l.google.com:19302"
            - name: JICOFO_AUTH_USER
              value: "focus"
            - name: JVB_TCP_HARVESTER_DISABLED
              value: "true"
            - name: JVB_AUTH_USER
              value: "jvb"
            - name: JVB_PORT
              value: "30300"
            - name: JVB_AUTH_PASSWORD
              value: "afa13ada"
            - name: JICOFO_AUTH_PASSWORD
              value: "adaad134"
            - name: JVB_BREWERY_MUC
              value: "jvbbrewery"
            - name: TZ
              value: "UTC"
            - name: XMPP_MUC_DOMAIN
              value: "muc.meet.bettercoffee.dev"

Next, create a service for Jitsi videobridge.

filename is jvb-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: jvb
  namespace: jitsi
spec:
  type: NodePort
  externalTrafficPolicy: Cluster
  ports:
  - name: "30300"
    port: 30300
    protocol: UDP
    targetPort: 30300
    nodePort: 30300
  - name: "4443"
    port: 4443
    targetPort: 4443  
  - name: "9090"
    port: 9090
    targetPort: 9090 
  selector:
    app: jvb

Here, you will create an issuer for the letsencrypt certificate.

create file jitsi-issuers.yaml

apiVersion: cert-manager.io/v1
kind: Issuer
metadata: 
  name: web
  namespace: jitsi
spec:
  acme:
    server: https://acme-v02.api.letsencrypt.org/directory
    email: [email protected]ld
    privateKeySecretRef:
      name: letsencrypt-prod
    solvers:
      - http01:
          ingress:
            class: nginx

Next create an ingress so that we can use https for jitsi domain.

create file ingress-jitsi.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  labels:
    service: web
  namespace: jitsi
  name: web
  annotations:
    nginx.ingress.kubernetes.io/proxy-buffer-size: "32k"
    nginx.ingress.kubernetes.io/affinity: "cookie"
    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-body-size: "512m"
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/enable-cors: "false"
    nginx.ingress.kubernetes.io/cors-allow-origin: "*"
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/use-regex: "true"
    cert-manager.io/issuer: "web"
spec:
  rules:
  - host: meet.bettercoffee.dev
    http:
     paths:
     - path: "/"
       pathType: Prefix
       backend:
         service:
           name: jitsi-web
           port:
             number: 80
  tls:
  - hosts:
    - meet.bettercoffee.dev
    secretName: jitsi-secret

Script for Deploying Video Conferencing Jitsi on K8s

In this steps, let's create a bash script to deploy the Jitsi video conferencing K8s config. For the first, we will create namespace for the Jitsi service in bash.

Create file apply.sh

#/bin/bash
create namespace jitsi
kubectl apply -f prosody-deploy.yaml
kubectl apply -f prosody-service.yaml
kubectl apply -f jvb-deploy.yaml
kubectl apply -f jvb-service.yaml
kubectl apply -f jicofo-deploy.yaml
kubectl apply -f web-deploy.yaml
kubectl apply -f web-service.yaml
kubectl apply -f jitsi-issuers.yaml
kubectl apply -f jitsi-ingress.yaml

After that, run apply.sh script to deploy Jitsi video conferencing to Kubernetes (K8s). Don't forget to point the public IP of the load balancer to public Jitsi domain.

chmod +x apply.sh
./apply.sh 
namespace/jitsi created
deployment.apps/prosody created
service/prosody created
deployment.apps/jvb created
service/jvb created
deployment.apps/jicofo created
deployment.apps/jitsi-web created
service/jitsi-web created
issuer.cert-manager.io/web created
ingress.networking.k8s.io/web created

After running apply.sh script, check and confirm that Jitsi is running on the Kubernetes. To check Jitsi, add -n for specific namespace used on Kubernetes with this:

"kubectl get pods -n jitsi".

Below is the output you should expect to see:

 kubectl get pods -n jitsi
NAME                        READY   STATUS    RESTARTS   AGE
jicofo-77c84d8b5c-s54vn     1/1     Running   0          56m
jitsi-web-fc7f9b58f-xqqg6   1/1     Running   0          56m
jvb-7bfd675565-8zcrd        1/1     Running   0          56m
prosody-846dd4d4f-lphdl     1/1     Running   0          56m

As you can see, Jitsi is running well on Kubernetes.

Testing Video Conferencing with Jitsi and K8s on the browser

In this section, let's check Jitsi on our browser. I used Google Chrome here but you can use whichever browser you want to check video conferencing Jitsi on K8s.

video conferencing

Wow, you have successfully deployed Jitsi on K8s! Isn't that amazing!

Now, let's create a room on Jitsi to try conference. Here, I tested with 3 participants, as you can see below:

video conferencing

Conclusion: How to Start Video Conferencing Jitsi on K8s

In conclusion, we discussed about deploying video conferencing with Jitsi on Kubernetes (K8s). If you want to deploy video conferencing with Jitsi on Docker, read Jitsi with Docker. You may also read on How to Deploy Wordpress on Kubernetes or How to Setup Kubernetes Nodes.

I think Jitsi has many features, and of course, it is also open source. You can build your server and then install Jitsi. If you want to develop an e-learning platform, Jitsi is also helpful.

I believe it's a great skill to learn today, and I am glad to have had the opportunity to write this for you. I hope you found this helpful and learned something meaningful from the post. Don't forget to like or comment if you appreciate the post or have any queries. If you face an unavailable recording error on Jitsi, consult this post I wrote not long ago to fix it. Please do not hesitate to ask me.
