# Shopping Cart Microservice

This is a Go REST API microservice for a typical shopping cart. The microservice has the following routes:

| # | HTTP Method | Endpoint            | Description                        |

| - | ----------- | ------------------- | ---------------------------------- |

| 1 | GET         | `/`                 | Base route                          |

| 2 | GET         | `/items`            | Returns a list of cart items        |

| 3 | POST        | `/items`            | Creates a new cart item             |

| 4 | GET         | `/item/{id}`        | Returns an item with the given `id` |

| 5 | PUT         | `/item/{id}`        | Updates an item with the given `id` |

| 6 | DELETE      | `/item/{id}`        | Removes an item from the cart with the given `id` |

## Running the app

To run the code, you need to build the application first. Run the command below to build the executable:

```bash

go get && go build

```

Now, run the executable:

```bash

./main

```

## Building the Docker image

To build the docker image, navigate to the root directory of the repo and run the command below:

```bash

docker build -t /shopping-cart-microservice .

```

Replace  with your dockerhub username. If you are pushing to a different registry, you might want to remove the  section entirely.

After building the image, you can run it using the command below:

```bash

docker run -p 8081:8080 /shopping-cart-microservice

```

This builds a docker container and runs it with port 8081 forwarded. If you open localhost:8081, you should see `Shopping Cart Microservice`.

## Deploying using Kubernetes

You can deploy the microservice using Kubernetes. First, you want to get Kubernetes running using Minikube, Kind, Docker Desktop, etc. Then, you'd want to apply the manifest. Run the command below to apply the manifest:

```bash

kubectl apply -f shopping-cart.yaml

```

This create a Kubernetes manifest and exposes port 8080 through a service.

Expose the deployment using this command:

```bash

kubectl expose deployment shopping-cart-deployment --type=LoadBalancer --port=80 --target-port=8080

```

Get the exposed URL using the command below:

```bash

minikube service shopping-cart-service --url

```
