使用Ingress创建基于HTTP的ALB
-
当创建
Ingress时，会创建对应的ALB，ALB和Ingress共享生命周期 -
它工作在7层，支持HTTP/HTTPS协议
在部署Ingress前，要先安装好AWS Load Balancer Controller 。
将下面内容保存为alb.yaml:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: alb-ingress
namespace: default
annotations:
kubernetes.io/ingress.class: alb
alb.ingress.kubernetes.io/target-type: ip # 当检查这个annotation时，AWS Load Balancer Controller会创建ALB
alb.ingress.kubernetes.io/scheme: internet-facing
alb.ingress.kubernetes.io/tags: Environment=dev,Team=test,audo-delete=no
spec:
rules:
- http:
paths:
- path: /*
backend:
serviceName: web-nginx-module
servicePort: 80

apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
namespace: default
labels:
app: web-nginx-module
spec:
replicas: 1
selector:

spec:

apiVersion: v1
kind: Service
metadata:

ports:

targetPort: 80
protocol: TCP
name: http
selector:

创建：
kubectl apply -f alb.yaml
创建完成后，在控制台看到ALB的详细信息：

利用Annotation, 可以自定义ALB的各种行为:
