# Deploying a Microservice Application to Kubernetes
## **Deploy the Stan's Robot Shop app to the cluster.**
**Clone the Git repo that contains the pre-made descriptors:**
```
cd ~/
git clone https://github.com/linuxacademy/robot-shop.git
```
**Since this application has many components, it is a good idea to create a separate namespace for the app:**
```
kubectl create namespace robot-shop
```
**Deploy the app to the cluster:**
```
kubectl -n robot-shop create -f ~/robot-shop/K8s/descriptors/
```
**Check the status of the application's pods:**
```
kubectl get pods -n robot-shop
```
**You should be able to reach the robot shop app from your browser using the Kube master node's public IP:**
```
http://$kube_master_public_ip:30080
```
## Scale up the MongoDB deployment to two replicas instead of just one.
**Edit the deployment descriptor:**
```
kubectl edit deployment mongodb -n robot-shop
```
**You should see some YAML describing the deployment object.**
Under `spec:`, look for the line that says `replicas: 1` and change it to `replicas: 2`.
Save and exit.
**Check the status of the deployment with:**
```
kubectl get deployment mongodb -n robot-shop
```
**After a few moments, the number of available replicas should be 2.**
```
kubectl get pods -n robot-shop
```
