Integration with external Neutron-Server

[f0o]

Hi,

I've gone through the vast of the code and I cant really find the specific integration from KubeStack and Neutron. So the Neutron-Plugin that is being loaded to Neutron-Server to talk to KubeStack.

We have a working OpenStack deployment for IaaS and we're looking into integrating H8S into this.

Any pointers on how to configure H8S/KubeStack with an external Neutron-Server?

Cheers!

Hi, @f0o, please refer https://docs.hypernetes.com/admin/deploy.html for deployments.

Specifically, you need to configure kubestack (/etc/kubestack.conf) and set --network-provider for kubelet/controller-manager.

Hi,

The deployment guide isn't very conclusive and does leave big margins of guesswork.

Regardless.

Kubelet points to kubestack and Kubestack points to keystone.

I dont see where kubestack is being registered or referred as neutron plugin.

Is kubestack continuously scanning all neutron networks for changes and then applying it?

Or how else is it being hooked into creating a network when neutron is being called?

It clearly isn't listening on the AMQP exhange either.

If kubestack really is scanning neutron for changes for every tenant, how is this going to scale?

Cheers, f0o

@f0o Kubestack is not a neutron plugin, it doesn't register itself to neutron. And it doesn't watch neutron changes either.

Instead, you need to create a network with kubectl:

# cat network.yaml
apiVersion: v1
kind: Network
metadata:
  name: net1
spec:
  tenantID: 065f210a2ca9442aad898ab129426350
  subnets:
    subnet1:
      cidr: 192.168.0.0/24
      gateway: 192.168.0.1

# kubectl create -f ./network.yaml
network "net1" created
# kubectl get network
NAME      SUBNETS          PROVIDERNETWORKID    LABELS    STATUS
net1      192.168.0.0/24                        <none>    Active

This will triger kubestack to call neutron creating a new network. See more at user guide.

Oh I assumed it was the other way around.

Thanks for clarifying!

I guess I'll just write a neutron plugin for kubestack/h8s then to integrate it in our OpenStack environment.
