Application Deployment Solution

Create a new deployment in the file quote.yaml.

quote.yaml looks like this:

--- 
apiVersion: apps/v1
kind: Deployment
metadata:
name: quote-service
namespace: development
labels:
  app: quote-service
spec:
replicas: 2
selector:
  matchLabels:
    app: quote-service
template:
  metadata:
    labels:
      app: quote-service
  spec:
    containers:
    - name: quote-container
      image: datawire/quote:0.5.0
      ports:
      - containerPort: 8080

Next challenge is to name the deployment and name the app label as quote-service.
- That would mean setting the name to the following:
```
metadata:
name: quote-service
```
The app label in this case would be:
```
labels:
  app: quote-service
```
Remember to change that label for all of the app fields.
Next is to use the development namespace and that has already been completed here:
```
namespace: development
```
Next requirement is to change the container name, which is:
```
  spec:
    containers:
    - name: quote-container
```
We want to run two replicas and this is done by:
```
spec:
replicas: 2
```
Use the image datawire, service by Ambassador Labs that generates random quotes.
```
      image: datawire/quote:0.5.0
```
We then create the pods using kubectl apply -f quote.yaml
Check kubectl get pods -n development.
How to use BusyBox to check the app works.
- kubectl exec -it <busybox pod name> -- /bin/sh
- Use wget to send a request to the pods.
  - Get the IP addresses with:
    - kubectl get pods -n development -o wide
    - wget <pod ip>:8080
      - If you get can't open 'index.html': File exits
        
        Check if the file is already in the busy box environment with ls
        
        Remove the index.html file and then run the command again.
