A demo collection of microservices for a video-streaming application that lives within the Knowledge Navigator ecosystem.

You need Docker and Docker-Compose installed to run this.

Boot EduTube from your terminal:

docker-compose up --build

Shutdown EduTube from your terminal:

docker-compose down

Give it some time to start, wait for the gateway service to come online. Then point your browser at http://localhost:4000/

• individual microservices
• packaging microservices
• publishing microservices (Docker)
• develop microservice application on development workstation (Docker Compose)
• testing microservices (Jest & Cypress)
• integrating third-party servers (MongoDB/RabbitMQ)
  • communicating between services (Async Messaging)
• storing data across services
• deploying microservices (Kubernetes)
• creating automated production infrastructure (Terraform)

A wiki can be found within this repository providing basic explanations of the technology stack and how they relate to microservices.

• Video Streaming: serve video to user [db]
• Video Storage: return video from cloud storage
• Video History: record viewing history [db]
• Video Upload: allow user data blob uploading to cloud
• Front-end Gateway: receive and relay browser front-end requests
• MongoDB Database Host

The following two msg events simulate multiple implementations receiving messages and how the various microservices will then handle them.

• "viewed-uploaded":

  • video upload publishes msg; metadata consumes msg

• viewed:

  • video streaming publishes msg; history consumes msg

Other events include the REST API gateway receiving frontend requests.
