OpenStack Cloud Controller Manager
Thank you for visiting the
OpenStack Cloud Controller Manager - An external cloud controller manager for running kubernetes in an OpenStack cluster.
External cloud providers were introduced as an Alpha feature in Kubernetes release 1.6. This repository
contains an implementation of external cloud provider for OpenStack clusters. An external cloud provider
is a kubernetes controller that runs cloud provider-specific loops required for the functioning of
kubernetes. These loops were originally a part of the
kube-controller-manager, but they were tightly
kube-controller-manager to cloud-provider specific code. In order to free the kubernetes
project of this dependency, the
cloud-controller-manager was introduced.
cloud-controller-manager allows cloud vendors and kubernetes core to evolve independent of each other.
In prior releases, the core Kubernetes code was dependent upon cloud provider-specific code for functionality.
In future releases, code specific to cloud vendors should be maintained by the cloud vendor themselves, and
cloud-controller-manager while running Kubernetes.
As such, you must disable these controller loops in the
kube-controller-manager if you are running the
openstack-cloud-controller-manager. You can disable the controller loops by setting the
external when starting the kube-controller-manager.
