Creating Highly Available clusters with kubeadm | Kubernetes
This page explains two different approaches to setting up a highly available Kubernetes cluster using kubeadm: With stacked control plane nodes. This approach requires less infrastructure. The etcd members and control plane nodes are co-located. With an external etcd cluster.
Demystifying High Availability in Kubernetes Using Kubeadm | Medium
Kubernetes High-Availability is about setting up Kubernetes, along with its supporting components in a way that there is no single point of failure. A single master cluster can easily fail, while a multi-master cluster uses multiple master nodes, each of which has access to same worker nodes.

How to Configure Applications for High Availability in Kubernetes
Kubernetes simplifies scheduling and orchestration but there are extra hurdles to develop and operate applications with high availability. Perhaps not all of the replicated Pods should be considered active. For example, a Kubernetes controller on CRDs should logically be just one instance.
High Availability :: Observability for Kubernetes
High Availability with Kubernetes. Earlier in this chapter we used the Prometheus Operator to launch a single instance of Prometheus within Kubernetes. To avoid the scenario of metrics being unavailable, either permanently or for a short duration of time, we can run a second instance of Prometheus.
