Machine API in OpenShift - Deep DIve

on YouTube ↗18m

" summary

Machine API exposes providerSpec templates to create/delete VMs across Azure/GCP/AWS/vSphere and maps each VM to a Kubernetes Machine object with five lifecycle phases: provisioning, provisioned, running, deleting, failed. A node link controller matches node.providerID to a Machine; nodes drain before the controller deletes the cloud VM. MachineSet acts like a ReplicaSet and recreates deleted machines. MachineHealthCheck automatically deletes unhealthy machines when they exceed maxUnhealthy. ClusterAutoscaler defines cluster-wide scaling rules; MachineAutoscaler sets min/max replicas per MachineSet.
