Step-by-Step Guide to Kubernetes Config Files

To create Kubernetes configuration files for a Deployment and Services using the provided YAML snippets (nginx-deployment.yaml, nginx-service.yaml) and to apply them to your Kubernetes cluster, follow these steps :

1. Create Configuration Files

nginx-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        ports:
        - containerPort: 8080

nginx-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  selector:
    app: nginx
  ports:
  - protocol: TCP
    port: 80
    targetPort: 8080

Save each of these YAML files in your local directory.

2. Apply Configurations to Kubernetes Cluster

Using Commands

Assuming you have kubectl configured to point to your Kubernetes cluster, follow these steps:

Apply Deployment Configuration:
```
 kubectl apply -f nginx-deployment.yaml
```
- This command will create or update the Deployment named nginx-deployment based on the YAML file provided.
Apply nginx-service Configuration:
```
 kubectl apply -f nginx-service.yaml
```
3. Verify Deployment and Services

After applying the configurations, you can verify their status and details using commands:
- Check Deployments, Services and pods:
```
  kubectl get deployments
  kubectl get services
  kubectl get pods
  // or for all
  kubectl get all | grep nginx
```

Summary

By following these steps, you can create Kubernetes configuration files , apply them to your Kubernetes cluster using kubectl apply and verify the deployment and services. This process ensures that your applications are deployed and accessible within your Kubernetes environment according to the specified configurations.
