Kubernetes internals
1:30Inside Kubernetes
The control plane and the nodes: API server, etcd, scheduler, controllers and kubelet, and how a pod gets created.
1:30What does etcd do?
etcd as the Kubernetes database: keys, leader election, Raft quorum, watches and backups.
1:09How the scheduler works
How kube-scheduler picks a node for a pod: filtering, scoring, binding, and how to influence it.
1:21Controllers and reconciliation
The control loop at the heart of Kubernetes: desired vs actual state, Deployments, ReplicaSets and the kubelet.
