Live stream third party API (OpenTok) using Nodejs and Docker

Basic understanding of OpenTok and Docker for self learning

OpenTok

• Create opentok session
• How to join session
• Create live stream HLS url
• Broadcast session
• Destroy broadcast
• Covered (HLS and WebRTC)

Description

You can use the OpenTok Node.js library to generate OpenTok sessions. Each session has a unique session ID, which you can use in an OpenTok client library to connect to an OpenTok session. (See "Joining a Session" for Web, iOS, or Android.)

Docker basic command

Create image file

• sudo docker build -t imageName .

Run image file

• docker run -it -p newPort:oldPort (example : 9000 : 3000) imageName

Run docker container in backend

• docker run -d -p 9000:3000 imageName

List of running container

• docker ps

Optimize docker build command like nodemon or volume

• In nodejs we use "nodemon index.js" (continuous watch our file)
• If nodemon not installed, install it and create again same imageFile
• docker run -it -p 9001:3000 -v $(pwd):/index node-docker // assign Different PORT

Push docker image on dockerhub

• check list of images(docker images)
• sudo docker tag node-docker:latest vishalims095/node-docker-test:v1 node-docker // image name latest // tag name vishalims095/node-docker-test:v1 // repo name and add tag it'll create a file
• sudo docker push vishalims095/node-docker-test:v1 v1 // pass tag name previously created using cmd
