Quick Start

Create the Serverless Kubernetes and copy the cluster config file to ~/.kube/config

Create NAT Gateway (Suggested)

Create NAT Gateway if you want to pull image from internet (e.g. Docker Hub), or your applications want to access internet.

Test It Out

Deploy nginx application

# Pull image from internet public URI with NAT GW
kubectl run nginx --image nginx:1.13 --replicas=3

# or pull image from Aliyun Container Registry (ACR) through VPC internal URI
kubectl run nginx --image registry-vpc.cn-shanghai.aliyuncs.com/denverdino/nginx:1.13.12 --replicas=3

Expose nginx with Elastic Load Balancer(ELB) service

kubectl expose deployment nginx --port=80 --target-port=80 --name=nginx-svc --type=LoadBalancer

Get the application status

kubectl get deployment nginx
kubectl get pod -l run=nginx
kubectl get service nginx-svc

Access nginx application

LB_ENDPOINT=$(kubectl get service nginx-svc -o jsonpath="{.status.loadBalancer.ingress[*].ip}")

# Open browser with URL in MacOSX
open http://${LB_ENDPOINT}

Delete the nginx application

kubectl delete deployment nginx

Delete the nginx service

kubectl delete service nginx-svc
