kube-vxlan-controller's Issues

Scaling deployment results in duplicated IP adresses in replicas

Hi,

I have tried to scale a deployment with replicas=2, unfortunately both replicas were assigned the same IP address, as set in the annotation;

apiVersion: v1
items:
- apiVersion: apps/v1
  kind: Deployment
  metadata:
    creationTimestamp: null
    labels:
      run: a
      vxlan.openvnf.org: "true"
    name: a
  spec:
    progressDeadlineSeconds: 2147483647
    replicas: 2
    revisionHistoryLimit: 2147483647
    selector:
      matchLabels:
        run: a
        vxlan.openvnf.org: "true"
    strategy:
      rollingUpdate:
        maxSurge: 1
        maxUnavailable: 1
      type: RollingUpdate
    template:
      metadata:
        annotations:
          vxlan.openvnf.org/networks: |
            vxeth1
              ip=**192.168.11.2/24**
              route=192.168.12.0/29:192.168.11.1
        creationTimestamp: null
        labels:
          run: a
          vxlan.openvnf.org: "true"

After both replicas have deployed, I see the same IP address in both replicas:

Is there a way to specify a subnet but not a hard-coded IP address in the annotation?

Thanks!

VXLAN issue with deployment kind "Statefulset"

Good day,

We have noticed that there is problems assigning vxlan interfaces to pods which are deployed as “StatefulSets”, problem appears in case these statefuls set pods are upgraded or deleted and problem solves it self after vxlna controller has been restarted.
Has this kind of issue been noticed already and has a fix or will have?

kube-vxlan-controller not running on kubernetes 1.16.1

kube-vxlan-controller not running correctly on kubernetes 1.16.1

apiVersion must be changed to apps/v1
selector and label must be added
when running the deployment it runs for couple of seconds, crashes and restarts.
