<s>[INST] Write a k8s deployment file that creates an Nginx instance with two replicas. Then, exposes the deployment using a node port type service on port 30080. [/INST] Here is an example deployment that creates an Nginx instance with two replicas and exposes the deployment using a node port type service on port 30080:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:latest
          ports:
            - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  type: NodePort
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
      nodePort: 30080</s>\ <s>[INST] What variable would I rename if I wanted to call these deployments a custom name? [/INST] If you wanted to call these deployments a custom name, you would rename the metadata.name variable in both the Deployment and the Service objects. For example, if you wanted to call them my-nginx, you would change the following lines:

metadata: name: nginx-deployment

to

metadata: name: my-nginx-deployment

and

metadata: name: nginx-service

to

metadata: name: my-nginx-service</s>
