## 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
|
|
``` |
