This directory contains a number of examples of how to run real applications with Serverless Kubernetes of Alibaba Cloud
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
