Following is my setup

• Kubernetes cluser with a master node and worker node. (IP -
  192.168.55.40/41)

  • kubectl version - v1.4.5
  • Both nodes running coreos

• Devstack single node setup on Ubuntu 14.04 (IP - 192.168.55.60)

  stack@vagrant-ubuntu-trusty-64:~/devstack$ neutron --version 6.0.0

I am trying to use openstack's loadbalancer to load balance a service running in the k8s cluster. I have made the following changes.

• Added the following lines to kubernetes-apiserver.service and
  kubernetes-controller-manager.service

  --cloud_config=/etc/sysconfig/kube_openstack_config

  --cloud_provider=openstack

• Following are the contents of /etc/sysconfig/kube_openstack_config

  [Global] auth-url=http://192.168.55.60/identity_admin username=admin password=password tenant-name=admin region=regionOne

• Restarted kubernetes-apiserver.service

Now when I create a service with type - Loadbalancer, service gets created, but no change in Openstack side.

I had checked the logs on the system with journalctl and it showed an error regarding the cloud_config file.

plugins.go:80] Couldn't open cloud provider configuration /home/core/kube_openstack_config

The file exists and read permission is given for all users. Any idea on what could be wrong?
