+# Introduction to Kubernetes: Services
+
+## Create a Kubernetes cluster 
+
+Firstly, we will need a Kubernetes cluster and will create one using [kind](https://kind.sigs.k8s.io/)
+
+```
+kind create cluster --name services --image kindest/node:v1.31.1
+```
+
+Test the cluster 
+
+```
+kubectl get nodes
+NAME                     STATUS   ROLES           AGE     VERSION
+services-control-plane   Ready    control-plane   5m48s   v1.31.1
+```
+
+## Deploy a few pods
+
+Let's deploy a few pods using a Kubernetes Deployment. To understand services, we need to deploy some pods that become our "upstream" or "endpoint" that we want to access. </br>
+
+```
+kubectl apply -f kubernetes/deployments/deployment.yaml 
+```
+
+## Deploy a service
+
+We can now deploy a Kubernetes service that targets our deployment:
+
+
+```
+kubectl apply -f kubernetes/services/service.yaml
+```
