keepalived - Keepalived

  •    C

The main goal of the keepalived project is to add a strong & robust keepalive facility to the Linux Virtual Server project. It implements a multilayer TCP/IP stack checks. Keepalived implements a framework based on three family checks : Layer3, Layer4 & Layer5. This framework gives the daemon the ability of checking a LVS server pool states. Keepalived can be sumarize as a LVS driving daemon. Keepalived implementation is based on an I/O multiplexer to handle a strong multi-threading framework. All the events process use this I/O multiplexer.

kubeadm-ha - Kubernetes high availiability deploy based on kubeadm (for v1

  •    Smarty

kube-apiserver: exposes the Kubernetes API. It is the front-end for the Kubernetes control plane. It is designed to scale horizontally – that is, it scales by deploying more instances. etcd: is used as Kubernetes’ backing store. All cluster data is stored here. Always have a backup plan for etcd’s data for your Kubernetes cluster. kube-scheduler: watches newly created pods that have no node assigned, and selects a node for them to run on. kube-controller-manager: runs controllers, which are the background threads that handle routine tasks in the cluster. Logically, each controller is a separate process, but to reduce complexity, they are all compiled into a single binary and run in a single process. kubelet: is the primary node agent. It watches for pods that have been assigned to its node (either by apiserver or via local configuration file) kube-proxy: enables the Kubernetes service abstraction by maintaining network rules on the host and performing connection forwarding. keepalived cluster config a virtual IP address (, this virtual IP address point to k8s-master01, k8s-master02, k8s-master03. nginx service as the load balancer of k8s-master01, k8s-master02, k8s-master03's apiserver. The other nodes kubernetes services connect the keepalived virtual ip address ( and nginx exposed port (16443) to communicate with the master cluster's apiservers.

kube-keepalived-vip - Kubernetes Virtual IP address/es using keepalived

  •    Go

AKA "how to set up virtual IP addresses in kubernetes using IPVS - The Linux Virtual Server Project". The issue is that it does not provide High Availability because beforehand is required to know the IP addresss of the node where is running and in case of a failure the pod can be be moved to a different node. Here is where ipvs could help. The idea is to define an IP address per service to expose it outside the Kubernetes cluster and use vrrp to announce this "mapping" in the local network. With 2 or more instance of the pod running in the cluster is possible to provide high availabity using a single IP address.
