Greetings

Hi! all, Welcome to my project. I hope this will be useful thing. :)

p.s. And I hope that some guy help me. If you are interested in this, please contact me. thank you.

Intro

OaaS is "OpenStack as a Service".
MAINTAINER: Jung-In.Jung (call518@gmail.com)
2018-06-20 ~ Now

Goals

Auto-Provisioning OpenStack, Based on Kubernetes(k8s).
Scalaing for LB/HA.
Supoort Provisioning Almost OpenStack Releases. (Newton/Ocata/Pike/Queens/...)
Simple and Dynamic Configuration.
Auto Failover/Failback.

Tutorial

System Env. & Arch.

Requirements.

General Kubernetes Cluster.
- kubernetes Installation guide
All k8s Worker nodes have to sync Time (e.g. chrony, ntp)
k8s worker nodes for neutron-server/nova-compute need to load openvswitch/ebtables/ip_vs kernel module.
- Run contents of host_kernel_modules_for_oaas.sh on compute/network role(label) woker nodes.
Quorum PODs (Replica is have to 2n+1)
- galera-etcd
- galera
- rabbitmq

Env.

(Note) We have tested this tutorial with 6 VMs on VirtualBox Env. If u want, any env is possible. (eg. physical machines)

(Note) We use NFS for cinder backend storage for simple tutorial, but soon we will change to ceph back-end storage.

Spec. of Physical Host

Processor: Intel Core i5-6500 (3.2GHz)
Memory: 32GB
Storage: SSD (2TB)
NIC: Intel(R) Ethernet Connection (5) I219-LM

Spec. of each VM

(Note) Maybe, you need big RAM. if not, reduce number of replicas.

CentOS-7 x86_64
2 EA vCPUs
vRAM: 2GB ~ 6GB
100 GB vDisk
1 EA NIC

Spec. of k8s

This is versions of packages that i have tested.

docker-ce-18.06.0.ce-3.el7.x86_64
kubernetes-cni-0.6.0-0.x86_64
kubectl-1.11.1-0.x86_64
kubelet-1.11.1-0.x86_64
kubeadm-1.11.1-0.x86_64

VM OS Env.

Deploy Tutorial

Node Labels (Role)

(!) Network(neutron-sever) worker nodes must be separated/dedicated. (network=true)

[k8s-master]# kubectl get node --show-labels

<Examples>

[k8s-master]# kubectl scale --replicas=4 statefulset.apps/cinder
[k8s-master]# kubectl scale --replicas=5 statefulset.apps/galera (must 2n+1)

Concept of IaaS, PaaS, SaaS

Cloud 2017. 9. 20. 10:27

Goal은 똑같다... "밥먹자!!"

SaaS "Just enjoy!"

PaaS "Cooking is my pleasure!"

IaaS "Ooooops!, OMG!!!, I'm hungry!!"

(철지난 개념 정리를 또 끄적이고 떠들게 될줄이야..... 그것도 자칭 클라우드 전문가에게....... 싫타 정말.... IaaS, PaaS, SaaS... 구분짓는다는게 참 우스운 일이긴 하지만, 어쩌겄어... 대화를 시작이라도 해볼려면... 쿨럭...)
