Kubernetes – Services

A Service is an abstraction which defines a logical set of Pods and a policy by which to access them (sometimes this pattern is called a micro-service).

• Create a YAML file

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  selector:
    app: my-nginx
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80
    nodePort: 30085
  type: NodePort

• Run or apply

kubectl create -f <yaml-file>
kubectl apply -f <yaml-file>

Working with services in the cluster

kubectl get service

kubectl describe service <service-name>

kubectl delete service <service-name>
