# Crowdsourced radio station

### How this works?

Checkout the slides at the link below.

https://docs.google.com/presentation/d/e/2PACX-1vQqA42MCq5GiVDXQ_O2DU1hfi1XxY1MvQ_sFfEq17x6Ue-We8JyaG1KJEGQh-sSjELzZM34cyx3w1T0/pub?start=false&loop=false&delayms=3000

### Instructions to run

- Clone this repo and the [frontend client](https://github.com/littlewonder/upnext-frontend).

- Copy `.env.tempalte` to `.env`, and edit the required variables. Make sure the cluster variables have a reachable IP address.

- Start `postgres`

```

docker-compose up postgres

```

- Start the discovery service.

```

docker-compose up discovery

```

- Start as many services as you want (either in same shell, or different shell, as per your convenience).

```

# for same shell

docker-compose up backend_3030 backend_4040 backend_5050

# for different shells

docker-compose up backend_3030

docker-compose up backend_4040

docker-compose up backend_5050

```

- Start `nginx` for load-balancing the frontend client with backend.

Make sure `nginx-load-balancer.conf` has the right IP addresses.

```

docker-compose up nginx

```

- Visit to the directory where you cloned the frontend, and run the command below. You might need to update `google login client ID` in the [frontend code](https://github.com/thelittlewonder/upnext-frontend/blob/master/src/components/SignInContainer.vue#L52).

```

npm install

PORT=8080 API_PORT=8000 npm run dev

```
