I have multiple MSA on k8s on GKE. Each is on separate subdomain like:
I have it in single ingress:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: main-ingress
annotations:
kubernetes.io/ingress.global-static-ip-name: lalala-ip-1
kubernetes.io/ingress.allow-http: "false"
spec:
tls:
- hosts:
- msa1.example.com
secretName: msa1-tls
backend:
serviceName: sink
servicePort: 80
rules:
- host: msa1.example.com
http:
paths:
- path: /.well-known/*
backend:
serviceName: letsencrypt
servicePort: 80
- path: /*
backend:
serviceName: lalala
servicePort: 80
- host: msa2.example.com
http:
paths:
- path: /*
backend:
serviceName: lalala2
servicePort: 80
... and all is nice.
The thing is, that I want to have each MSA in separate file.
Problem is this kubernetes.io/ingress.global-static-ip-name: lalala-ip-1
line. If I have it in two ingresses only first started is bounded to IP, but other ones no.
Is there a way, to share IP on GKE ingress controller between two ingresses?
A way around it could be to run your own nginx-ingress controller in your cluster and expose it via LoadBalancer service type. Then you would have 1 IP for your ingress and be able to serve all ingresses via nginx controller by adding annotation kubernetes.io/ingress.class: "nginx"

Confirmed my comment:
Only one resource at a time can use a static external IP address.
