My question is regarding quotas of Google Kubernetes Engine.

I have an instance running 4 pods, each pod is referring to a microservice (api) containing 3 containers:

• Spring Boot App


• esp: endpoints


• cloudsqlproxy

For each pod (microservice), I have a deployment yaml which includes a nodeport service. Along with that, there is an ingress mapping all these services. Now
I need to deploy another microservice (pod with same 3 containers), but the quota of 5 backend services is in the limit.

I dont know if I'm doing something wrong or this quota is very small. I think, four microservices is very little for a technology that supports this approach.

So, Am I missing something in this architecture / configuration? Something that I'm doing wrong?

Here is my Ingress configuration:

apiVersion: extensions/v1beta1

kind: Ingress

metadata:

  name: sigma-ingress

  annotations:

    # type of controller to use:

    kubernetes.io/ingress.class: "gce"

    # CORS

    ingress.kubernetes.io/enable-cors: "true"

    #

    # ingress.kubernetes.io/rewrite-target: /

    # Don't rediret to HTTPS

    ingress.kubernetes.io/ssl-redirect: "false"

    # Block HTTP requests

    kubernetes.io/ingress.allow-http: "false"

spec:

  tls:

  - secretName: sigma-ssl

  rules:

  - http:

      paths:

      - path: /agro/*

        backend:

          serviceName: api-agro

          servicePort: 443

      - path: /fazendas

        backend:

          serviceName: api-fazenda

          servicePort: 443

      - path: /fazendas/*

        backend:

          serviceName: api-fazenda

          servicePort: 443

      - path: /clima

        backend:

          serviceName: api-clima

          servicePort: 443

      - path: /clima/*

        backend:

          serviceName: api-clima

          servicePort: 443

      - path: /ocorrencias

        backend:

          serviceName: api-inspecao

          servicePort: 443

      - path: /ocorrencias/*

        backend:

          serviceName: api-inspecao

          servicePort: 443

Thanks in advance

You are probably hitting the GCP Load balancer backend limit which is usually low (mine is 9) This if you several other load balancers with configured backends that are making you hit that limit and you are mentioning that you already have other NodePort services (are they using another load balancer with a different backend?)

Your ingress should use just one backend that points to all the nodes in your cluster.

Besides the gcloud command line, you can see the limit from the UI.

You can also see the details on the load balancer that is serving your Ingress.

And you can see all your load balancer too:

You can request a backend quota increase from GCP, or you can remove unused load balancers.

You can check the list of backends with gcloud compute backend-services list or go to the quotas page in the gcloud web console and it should show you both your allowed usage and current usage. You should also be able to see there at what level it is set from (it may come from a parent project policy). You can also request an increase from the same page using the edit button.
