Managed Kubernetes Service for Public Cloud with Openstack and Kubernetes
summary
Deployed a managed Kubernetes service for a Vietnamese public cloud that replaces OpenStack Magnum (cluster creation often 10–15 minutes and unstable) and rejects Rancher/RKE and early Gardener for being insufficient or incompatible. Architecture runs Kubernetes control plane components as statefulsets on a sys cluster managed by an orchestrator called BKE orchestrator, uses OpenStack Senlin for worker auto scaling and an OpenVPN tunnel between control plane and worker networks, adds a custom cloud-controller-manager and CNI, and faces issues like a routing failure with Weave and a provider_id bug that forces node removal and rejoin.
