# 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}
|
|
```
|
|
|
|
```
