host monitors by kubernetes¶
https://blueprints.launchpad.net/masakari/+spec/host-monitors-by-kubernetes
Problem description¶
When using Openstack on Kubernetes, the current host monitoring process lacks efficiency and simplicity, requiring additional software such as Consul or Pacemaker.
Proposed change¶
This spec is mainly to add a new host monitoring driver to masakari-monitors using the Kubernetes-client. By leveraging the Kubernetes API, kubernetes-native openstack operator can efficiently retrieve and monitor the status of the host (node) without the complexities associated with external configuration tools like Consul or Pacemaker.
Administrator can set the host monitoring driver to Kubernetes in the host configuration.
