Microservices Project : A Video Converter Service

This project was my first introduction to developing microservices and deploying them to a local Kubernetes cluster(minikube).
Multiple repos were combined for your convinience.

---

Sub Repos for each service:-

1. Main repo https://github.com/harsh098/microservice-deploy/
2. Authentication Service https://github.com/harsh098/microservice-deploy-auth
3. Gateway Service https://github.com/harsh098/microservice-deploy-gateway-svc
4. RabbitMQ deployment https://github.com/harsh098/microservice-deploy-rabbitmq
5. Converter Service https://github.com/harsh098/microservice-deploy-converter-service
6. Notification Service https://github.com/harsh098/microservice-deploy-notification-service

Setting up your Local kubernetes cluster

Part-I. Start Docker, mysqld, and mongod

Assuming you have mysql and mongo installed on local and mongo is configured to allow access without authentication.

1. Configure You mysqld.service and mongod.service to allow all hosts i.e. 0.0.0.0 (for all IPv4) or :: (for all IPv6 abd IPv4)
   sudo systemctl start docker mysqld and mongod
2. Edit init.sql as instructed in the file
3. run init.sql

Part-II. Setting Up minikube and conatiners

1. Run the following commands

minikube start
eval $(minikube -p minikube docker-env)

2. Clone the git repo
3. cd into the directory
   Run the following command ./builder.py .
4. edit following secret.yaml files for your setup
   1. JWT_SECRET in `auth_service/manifests/secret.yaml here
   2. GMAIL_ADDRESS and GMAIL_PASSWORD in notification_service/manifests/secret.yaml here
5. Run minikube ip

Part-III. Edit your DNS Records

Note: replace 192.168.49.2 with the address in the output of minikube ip
Add the following lines to /etc/hosts (in Mac/Linux) or C:\Windows\System32\Drivers\etc\hosts (in Windows)

  192.168.49.2   kubernetes.docker.internal
  192.168.49.2   vid2mp3.com
  192.168.49.2   rabbitmq-manager.com

Part-IV. Start the deployments

Run The following commands

1. cd into project directory

kubectl create -f auth_service/manifests
kubectl create -f gateway/manifests
kubectl create -f rabbit/manifests
kubectl create -f converter_svc/manifests
kubectl create -f notification_service/manifests

2. Mac and Windows Users need to run minikube tunnel in a separate terminal window

Running Demo

STEP-1 login via /login endpoint and get JWT

STEP-2 Upload video via /upload endpoint and validate using JWT

STEP-3 The video is processed and notification received on e-mail

STEP-4 Download the converted file using /download (validate using JWT)

Running Kubernetes cluster Objects

I. Pods

II. Ingresses

III. Deployments

IV. Persistent Volumes

V. Stateful Sets
