Two Methods to Deploy an Nginx Pod in Kubernetes

This guide shows two common ways to launch an Nginx container as a pod in a Kubernetes cluster.

Method 1 – Imperative commands: Pull the latest Nginx image and start a pod directly with

docker pull nginx:latest<br/>kubectl run --image=nginx:latest nginx-test-app --port=80

. After the pod is created you can inspect it with commands such as

kubectl get pod<br/>kubectl exec podname <command><br/>kubectl describe pod podname<br/>kubectl logs podname

.

Method 2 – Declarative YAML manifest: Create a nginx.yaml file that describes the pod:

apiVersion: v1<br/>kind: Pod<br/>metadata:<br/>  namespace: default<br/>  name: newnginx<br/>spec:<br/>  containers:<br/>  - image: nginx:latest<br/>    imagePullPolicy: IfNotPresent<br/>    name: nginx-test-app<br/>    ports:<br/>    - containerPort: 80<br/>      protocol: TCP

Apply the manifest with the standard kubectl lifecycle commands:

kubectl create -f nginx.yaml<br/>kubectl apply -f nginx.yaml<br/>kubectl delete -f nginx.yaml
