# Smoke Test
This lab walks you through a quick smoke test to make sure things are working.
## Test
```
kubectl run nginx --image=nginx --port=80 --replicas=3
```
```
deployment "nginx" created
```
```
kubectl get pods -o wide
```
```
NAME READY STATUS RESTARTS AGE IP NODE
nginx-2032906785-ms8hw 1/1 Running 0 21s 10.200.2.2 worker2
nginx-2032906785-sokxz 1/1 Running 0 21s 10.200.1.2 worker1
nginx-2032906785-u8rzc 1/1 Running 0 21s 10.200.0.2 worker0
```
```
kubectl expose deployment nginx --type NodePort
```
```
service "nginx" exposed
```
> Note that --type=LoadBalancer will not work because we did not configure a cloud provider when bootstrapping this cluster.
Grab the `NodePort` that was setup for the nginx service:
```
NODE_PORT=$(kubectl get svc nginx --output=jsonpath='{range .spec.ports[0]}{.nodePort}')
```
### Create the Node Port Firewall Rule
#### GCP
```
gcloud compute firewall-rules create kubernetes-nginx-service \
--allow=tcp:${NODE_PORT} \
--network kubernetes
```
Grab the `EXTERNAL_IP` for one of the worker nodes:
```
NODE_PUBLIC_IP=$(gcloud compute instances describe worker0 \
--format 'value(networkInterfaces[0].accessConfigs[0].natIP)')
```
#### AWS
```
SECURITY_GROUP_ID=$(aws ec2 describe-security-groups \
--filters "Name=tag:Name,Values=kubernetes" | \
jq -r '.SecurityGroups[].GroupId')
```
```
aws ec2 authorize-security-group-ingress \
--group-id ${SECURITY_GROUP_ID} \
--protocol tcp \
--port ${NODE_PORT} \
--cidr 0.0.0.0/0
```
Grab the `EXTERNAL_IP` for one of the worker nodes:
```
NODE_PUBLIC_IP=$(aws ec2 describe-instances \
--filters "Name=tag:Name,Values=worker0" | \
jq -r '.Reservations[].Instances[].PublicIpAddress')
```
---
Test the nginx service using cURL:
```
curl http://${NODE_PUBLIC_IP}:${NODE_PORT}
```
```
