# Kustomize - Common Labels
## Requirements
1. Running Kubernetes cluster
2. Kubctl version 1.14 or above
## Objectives
In the current directory there is an app composed of a Deployment and Service.
1. Write a kustomization.yml file that will add to both the Service and Deployment the label "team-name: aces"
2. Execute a kustomize command that will generate the customized k8s files with the label appended
## Solution
1. Add the following to kustomization.yml in someApp directory:
```
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
commonLabels:
team-name: aces
resources:
- service.yml
- deployment.yml
```
2. Run `kubectl apply -k someApp`
