Stackube Architecture
|
|
=======================
|
|
|
|
This page describes the architecture of stackube.
|
|
|
|
==========
|
|
Overview
|
|
==========
|
|
|
|
Stackube is a Kubernetes-centric OpenStack distro. It uses Kubernetes, instead of Nova, as the compute
|
|
fabric controller, to provision containers as the compute instance, along with other OpenStack
|
|
services (e.g. Cinder, Neutron). It supports multiple container runtime technologies, e.g. Docker,
|
|
Hyper, and offers built-in soft/hard multi-tenancy (depending on the container runtime used).

Components
|
|
===========
|
|
|
|
1. Standard OpenStack Compoents
|
|
|
|
* OpenStack Keytone
|
|
* OpenStack Neutron
|
|
* OpenStack Cinder
|
|
|
|
2. Standard Kubernetes Components
|
|
|
|
* Etcd: the storage of kubernetes.
|
|
* Kube-apiserver: the API, authn/authz and admission control of kubernetes.
|
|
* Kuber-controller-manager: the brain of kubernetes, ensure the state of kubernetes cluster.
|
|
* Kube-scheduler: the scheduler of kubernetes.
|
|
* Kubelet: the container lifecycle and volume manager of kubernetes.
|
|
* Frakti&HyperContainer: a hypervisor-based container runtime.
|
|
* Docker: docker container runtime.
|
|
|
|
3. Stackube addons
|
|
|
|
* Stackube-controller: tenant and network manager.
|
|
* Stackube-proxy: service discovery and load balancing, replacement of kube-proxy.
|
|
* Kubestack: the CNI network plugin, which connects containers to Neutron network.
