Nginx ingress, GKE and static IP #1281

Closed guizmaii closed 7 years ago

guizmaii commented 7 years ago

Hi,

Do you agree if I say that, currently, it's impossible to config a Nginx Ingress (kubernetes.io/ingress.class: "nginx") in GKE that uses a previously reserved (gcloud compute addresses create <static_ip_id> --global) static IP ?

Because I'm not able to make it works.

Until now, I understood that there're two possible Ingress configurations:

Do we agree on that ?

Because of the current limitations of the Google Cloud HTTP(S) load balancer, I chose to use the Nginx Ingress but I'm not able to bind the static to my cluster.

Do you have an idea to help me ?

My problem seems to be the same as explained here: https://github.com/kubernetes/ingress/issues/280

the EXTERNAL-IP of nginx-ingress-lb is keeping pending.

I'm using this version: nginx-ingress-controller:0.8.3 because the 0.9.0-betaX version don't work with kube-lego (https://github.com/jetstack/kube-lego)

I remarked that the --publish-service Nginx Ingress command doesn't exist in the 0.8.3 version. Could this be the problem ? Answer to my own question: It's not. I deployed the https://github.com/kubernetes/ingress/tree/master/examples/static-ip/nginx with a pre-reserved static IP and it doesn't work. The Ingress never get associated to the static IP

Thanks, Jules :)

Ok after some tests with the "static ip" example, I could affirm that we can bind a Google Cloud pre-reserved static IP to a Nginx Ingress if the static IP is a regional one.

But It seems not to work with global IPs.

Is this a normal behavior ? is this documented somewhere ?

It's documented on the GCE side at https://cloud.google.com/compute/docs/load-balancing/network/forwarding-rules.

guizmaii commented 7 years ago

OK thanks. Maybe it could be useful to explain that in your doc too, no ?

aledbf commented 7 years ago

@guizmaii can we close this issue?

Hi, can someone add the correct annotation to bind the regional static IP? I can't seem to find it anywhere.

Thanks :)

jdalegonzalez commented 6 years ago

@itaimalek As far as I know, there isn't an annotation to bind to the regional IP. Instead, you reserve a regional IP and then use it as the IP address inside your yaml file.

spec:
  type: LoadBalancer
  externalTrafficPolicy: Local
  loadBalancerIP: @GKE_STATIC_IP_ADDRESS  # static IP pre-allocated.

Yes, I git it eventually :) Thanks !

The configuration suggested by @jdalegonzalez does not work for me. My ingress controller load balancer gets the correct fixed IP but every request returns a 503. @itaimalek What ended up being a working configuration for you?

Edit: nevermind, it does work using the above config. I had an error in my application that I had missed.

jdalegonzalez commented 6 years ago

Did you look at the ingress logs? 503 is bad gateway, right? I had this problem when the ingress couldn't load the GeoLite.dat file due to lack of memory. For me, removing the memory constraint in the yaml file solved it.
