# whoami EmilienM on IRC 25 old Student in Master Degree (Part time) OpenStack Operator at eNovance : Maintain and manage eNoCloud (Public Cloud using OpenStack) Building CloudWatt Cloud OpenStack contributor (HA stuffs + doc)
OpenStack Created in 2010 by NASA & RackSpace Licence Apache 2.0 Manage IaaS Open-Source Framework API, Plugins, Drivers Multi-tenancy, Scalable, multi-plateform Developed in Python
OpenStack in the IaaS* IaaS Components OpenStack Projects Nova Compute (Virtual Machines) Swift (Object Storage) Storage Cinder (Block Storage) Quantum Networking (Virtual Networking) * Infrastructure as a Service
Get the VM Download it : http://goo.gl/01Dr5 Ubuntu 12.04 with Cloud Archives root / password MySQL installed Scripts already in /root Packages downloaded, NOT installed Usable with VMware & Virtual Box
Networking 1 NIC for Management (192.168.0.0/24) → « NAT » 1 NIC for Data (10.10.10.0/24) → « Internal » 1 NIC for Public (220.127.116.11/24) → « Bridge » with WLAN or Ethernet
Common Services MySQL (Backend Databases) → Used by Keystone, Glance, Nova, Cinder, and Quantum. RabbitMQ (Middleware for queuing) → Used by Glance, Nova, Cinder and Quantum.
Keystone : Identity as a Service 1/2 Identity (Users, tenants, roles, metadata) → Can be backed by LDAP Token : Authentify requests from user / tenant Service Catalog : Endpoint registry Policy Services : Rule-based authorization engine
Keystone : Identity as a Service 2/2 1) Install packages & Configuration 2) Synchronize the Database 3) Create Users, Tenants, Roles 4) Create Services and Endpoints 5) Test the identity.
Glance : Image Delivery 1/2 Discovering, Registring, Retrieving Virtual Machine images. The images can be stored in : regular FS, RBD (Ceph), Amazon S3 or Swift. Disk Formats : raw, vhd, vmdk, vdi, iso, qcow2, aki, ari, ami. Container Formats : bare, ovf, aki, ami, ari.
Cinder : Block Storage 1/2 Formerly « nova-volume » Create / Delete / Attach / Detach volumes to a VM Storage backed by : NFS, iSCSI, SolidFire, NetAPP, etc...
Cinder : Block Storage 2/2 1) Prepare the second disk with LVM 2) Install packages & Configuration 3) Synchronize the Database 4) Create a 1GB volume for testing
Quantum : Networking 1/2 Provides connectivity to Vms Manage L2 & L3 with an API Networking backed by plugins : Open- vSwitch, Linux Bridge, Cisco, OpenFlow (BigSwitch, Floodlight, NEC, Ryu, etc), Midonet (Midokura) and NVP (Nicira / Vmware).
Quantum : Networking 2/2 1) Install packages & Configuration 2) Create virtual L2 with Open-vSwitch 3) Create virtual L3 with the script 4) Configure L3 Agent
Nova : Compute Service 1/2 Manages Virtual Machines Libvirt friendly Hypervisors supported : KVM / qemu, Xen, Hyper-V (all ready for production) Interact with other services (Cinder, Quantum, Glance, Keystone, etc)
Nova : Compute Service 2/2 1) Install packages & Configuration 2) Synchronize the Database 3) Configure the Hypervisor 4) Spawn a VM with CLI
Horizon : Dashboard 1/2 Developped with Python / Django Manage VMs, Images, Identity, Volumes Not yet full-integraded with Quantum : only L2 is working. L3 should be managed from CLI.
Horizon : Dashboard 2/2 1) Install the packages 2) Connect to the dashboard : → http://<ip>/horizon
Start your first VM ! Use demo tenant / user Check networking before Spawn a VM from CirrOS image Attach the virtual port to a floating IP (from Quantum CLI) Ping the VM SSH the VM Play with volumes
