## System Design Doc

The design choices made for the code base and what could be improved more is explained here:

### **System Setup (Assuming a Linux based System)**

Make sure that minikube, kubectl, docker & k9s are already installed on your device

Change Bind Address of the MongoDB to 0.0.0.0:

1. Open `/etc/mongod.conf`
2. change bindIp value to 0.0.0.0
3. save & exit
4. Restart mongodb by: sudo systemctl restart mongod

Make sure you change the port number of redis to 7779 from 6379 ( you can change in the redis.conf file) & it’s bind address. Here is how to do it: 

1. Open `/etc/redis/redis.conf`
2. Look for the **`bind`** directive in the configuration file.
3. Change it from `127.0.0.1` to `0.0.0.0`
4. Look for `port 6379` and change `6379` to `7779`

Append these to your /etc/hosts file:
```
192.168.49.2 kubernetes.docker.internal
192.168.49.2 rabbitmq-manager.com
192.168.49.2 datacollector.com
```

And enable ingress in minikube by doing:

`minikube addons enable ingress` 

`minikube addons enable ingress-dns`

### **How to Run?**

1. Run `minikube start` on your terminal to start a Minikube Kubernetes cluster.
2. In a separate terminal window, run **`minikube tunnel`** to establish a network tunnel to expose services running inside the Minikube cluster to your local machine.
3. Follow the below instructions to run each use case:
    - Run the below commands to deploy use cases on your local kubernetes cluster (minikube):
   ```
   kubectl apply -f ./gateway/manifests
   kubectl apply -f ./notifications/manifests
   kubectl apply -f ./submit/manifests
   kubectl apply -f ./rabbit/manifests
   kubectl apply -f ./spreadsheet/manifests
   kubectl apply -f ./translator/manifests
   ```

4. Use k9s to verify, if all pods are running successfully

Use the postman collection to test api routes:
