-
STEP 1 — Confirm cluster state (Minikube)
minikube status
If status shows Stopped / Not Running:
minikube start
(Wait until it reports minikube: Running and host: Running.)
-
STEP 2 — (Optional) Quick sanity: kubectl connectivity
kubectl version --short
kubectl cluster-info
If these fail with connection errors (e.g. connect: no route to host or failed to download openapi), ensure Minikube is running and your kubeconfig points to Minikube:
minikube start
kubectl config use-context minikube
-
STEP 3 — Create / confirm the YAML files
Create Deployment file:
nano nginx-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx
spec:
replicas: 2
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:stable
ports:
- containerPort: 80
Create Service file:
nano nginx-service.yaml
apiVersion: v1
kind: Service
metadata:
name: nginx-nodeport
spec:
type: NodePort
selector:
app: nginx
ports:
- port: 80
targetPort: 80
protocol: TCP
nodePort: 30080
-
STEP 4 — Apply the manifests
kubectl apply -f nginx-deployment.yaml
kubectl apply -f nginx-service.yaml
If validation fails due to API connectivity, you can (carefully) bypass client-side validation:
kubectl apply -f nginx-deployment.yaml --validate=false
But prefer fixing the API connectivity first.
-
STEP 5 — Verify Deployment and Pods
kubectl get deployments
# should show: nginx-deployment 2/2 <...>
kubectl get pods -l app=nginx
# should show 2 pods in STATUS: Running
kubectl describe deployment nginx-deployment
# view rollout details, events, and conditions
-
STEP 6 — Verify Service and NodePort
kubectl get svc nginx-nodeport
# Example output line: nginx-nodeport NodePort 10.96.x.x 80:30080/TCP
kubectl get svc nginx-nodeport -o yaml
# to confirm nodePort: 30080 and selectors
-
STEP 7 — Get Node IP and test access
If using Minikube:
minikube ip
# e.g. 192.168.94.2
Open in browser:
http://<MINIKUBE_IP>:30080
# Example: http://192.168.94.2:30080
Or test with curl:
curl -I http://$(minikube ip):30080
