wksctl - Open Source Weaveworks Kubernetes System

•    Go

Please note that the code has recently updated from ClusterAPI v1alpha1 to v1alpha3 and as a result Everything Has Changed While this note is in the README you may find inconsistencies in the code, and between the code, examples and documentation. Sorry about that. Feel free to still open issues and/or ask questions as below. wksctl allows simple creation of a Kubernetes cluster given a set of IP addresses and an SSH key. It can be run in a standalone environment but is best used via a GitOps approach in which cluster and machine descriptions are stored in Git and the state of the cluster tracks changes to the descriptions.

Helix - Cluster Management Framework

•    Java

Helix is a generic cluster management framework used for the automatic management of partitioned, replicated and distributed resources hosted on a cluster of nodes. It helps to perform scheduling of maintenance tasks, such as backups, garbage collection, file consolidation, index rebuilds, repartitioning of data or resources across the cluster, informing dependent systems of changes so they can react appropriately to cluster changes, throttling system tasks and changes and so on.

docker-redis-cluster - Dockerfile for Redis Cluster (redis 3.0+)

cluster-api - Home for the Cluster Management API work, a subproject of sig-cluster-lifecycle

•    Go

The Cluster API is a Kubernetes project to bring declarative, Kubernetes-style APIs to cluster creation, configuration, and management. It provides optional, additive functionality on top of core Kubernetes. Note that Cluster API effort is still in the prototype stage while we get feedback on the API types themselves. All of the code here is to experiment with the API and demo its abilities, in order to drive more technical feedback to the API design. Because of this, all of the prototype code is rapidly changing.

turing-pi-cluster - Turing Pi cluster configuration for Raspberry Pi Compute Modules

•    HTML

You might also be interested in another Raspberry-Pi cluster I've maintained for years, the Raspberry Pi Dramble, which is a Kubernetes Pi cluster in my basement that hosts www.pidramble.com. Other models of Raspberry Pi and Compute Modules may or may not work, but the main thing you need is a cluster with at least 7 GB of RAM and at least 12 available CPU cores (every current Pi has 4 CPU cores), otherwise not all of the software will be able to run well.

corvus - A fast and lightweight Redis Cluster Proxy for Redis 3.0

•    C

Corvus is a fast and lightweight redis cluster proxy for redis 3.0 with cluster mode enabled.Most redis client implementations don't support redis cluster. We have a lot of services relying on redis, which are written in Python, Java, Go, Nodejs etc. It's hard to provide redis client libraries for multiple languages without breaking compatibilities. We used twemproxy before, but it relies on sentinel for high availabity, it also requires restarting to add or remove backend redis instances, which causes service interruption. And twemproxy is single threaded, we have to deploy multiple twemproxy instances for large number of clients, which causes the sa headaches.

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 (192.168.20.10), 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 (192.168.20.10) and nginx exposed port (16443) to communicate with the master cluster's apiservers.

ksync - Sync files between your local system and a kubernetes cluster.

•    Go

ksync speeds up developers who build applications for Kubernetes. It transparently updates containers running on the cluster from your local checkout. This enables developers to use their favorite IDEs, such as Atom or Sublime Text to work from inside a cluster instead of from outside it. There is no reason to wait minutes to test code changes when you can see the results in seconds. You can also download the latest release and install it yourself.

redis-go-cluster - redis cluster client implementation in Go

•    Go

redis-go-cluster is a golang implementation of redis client based on Gary Burd's Redigo. It caches slot info at local and updates it automatically when cluster change. The client manages a connection pool for each node, uses goroutine to execute as concurrently as possible, which leads to its high efficiency and low lantency. redis-go-cluster has compatible interface to Redigo, which uses a print-like API for all redis commands. When executing a command, it need a key to hash to a slot, then find the corresponding redis node. Do method will choose first argument in args as the key, so commands which are independent from keys are not supported, such as SYNC, BGSAVE, RANDOMKEY, etc.
