Ubuntu 13.10 MAAS ( Metal as a service ) prat01

Here are installation logs when installing MAAS within KVM.

referred to http://maas.ubuntu.com/docs/about.html.

MAAS stands for Metal as a Service.

There are three key components,

region controller ( web UI, API )

cluster

nodes

I have installed these three components on the same server.

Here are trial and error logs when installing Ubuntu 13.10 MAAS within KVM.

KVM host

# tail -1 /etc/lsb-release ;uname -ri DISTRIB_DESCRIPTION="Ubuntu 13.04" 3.8.0-33-generic x86_64

[ about the VM for MAAS ]

OS: ubuntu 13.10 server 64bit

vNIC*1

vCPU*2

vHDD: 25GB

Memory 2GB

download Ubuntu 13.10 server ISO and build the VM from that ISO.

select “install MAAS”

configure this box as a new MAAS

installing..

on the MAAS VM, enable serial console to log on to that via “virsh console”

confirm the MASS VM has the internet connectivity.

after installing MAAS

access to http:// IP address/MAAS

needs to create an admin user for MAAS

on the CLI

# maas createsuperuser Username (leave blank to use 'root'): Email address: a@a Error: Enter a valid email address. Email address: a@foo.com Password: Password (again): Superuser created successfully.

login

after logging onto the MAAS.

set up for maas-cli

on the GUI

click Preferences

get MAAS keys which is required to use maas-cli.

on the CLI, logon to MAAS.

could I log on ??

# maas-cli login maas http://127.0.0.1/MAAS/api/1.0 API key (leave empty for anonymous access): You are now logged in to the MAAS server at http://127.0.0.1/MAAS/api/1.0/ with the profile name 'maas'. For help with the available commands, try:  maas-cli maas --help root@ubuntu-maas01:~#

import boot image

root@maas01:~# maas-cli maas node-groups import-boot-images Import of boot images started on all cluster controllers root@maas01:~# maas-cli maas node-groups list [    {        "cluster_name": "Cluster 254261ec-ea20-41ba-8fff-95f29cd1301f",        "status": 1,        "name": "master",        "uuid": "254261ec-ea20-41ba-8fff-95f29cd1301f"    } ]

it seems to take much(?) time to import boot image at first time…

list nodes.

root@ubuntu-maas01:~# maas-cli maas nodes accept-all [] root@ubuntu-maas01:~# maas-cli maas nodes list []

- cluster configuration

GUI -> click “cog” icon.

Cluster controllers..

no boot images..

seen from an output of tcpdump, maas seems to download boot images.

after succeeding in importing boot images, GUI shows:

add nodes via GUI

clieck “+ Add node”

add node called “test01”

after adding two nodes

on the CLI

how can I run these nodes?

seen from GUI message,

Node marked as using the default installer.

You can boot this node using Avahi-enabled boot media or an adequately configured DHCP server. See https://maas.ubuntu.com/docs/nodes.html for instructions.

I have not configured DHCP..
