I have look in to dozens on online document but none give me the exact steps and recommendation for deploying MAAS, Juju and OpenStack on Ubuntu.
There's plenty of documentation available but none discuss the whole project in one.
Can someone point me to a tutorial?
There isn’t a single guide to point you towards, mainly due to the size of the project and subsequent ways it can be tailored for an individual’s needs. The question itself spans four different software projects and multiple fields of technology including networking, virtualisation and storage configuration.
The most basic of guides can be found on Ubuntu’s Installing Canonical’s OpenStack Autopilot page. While at the other end of the spectrum you have Openstack’s Installation Guide for Ubuntu. Then once you are up and running you can then use Openstack’s Operations Guide
The best attempt at an overall guide is from the Openstack in the basement project and all his Ubuntu Openstack install videos.
To make things simpler people make use of the Openstack installer which handles Juju for you which is why a lot of guides don't mention any Juju configuration.
It's a bit difficult to find a single place that provides all the details.
However, I can help to some extent.
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:juju/stable
sudo add-apt-repository ppa:maas/stable
sudo add-apt-repository ppa:cloud-installer/stable
sudo apt-get update
sudo apt-get install maas
sudo maas-region-admin createadmin
sudo apt-get install etherwake
To get the version of the current MAAS installed
apt-cache policy maas{,-dns,-dhcp} | grep Installed -B1 -A1
In /etc/maas/templates/power/ether_wake.template, make the following changes:
#elif [ -x /usr/bin/wakeonlan ]
#then
# /usr/bin/wakeonlan $mac_address
elif [ -x /usr/sbin/etherwake ]
then
sudo /usr/sbin/etherwake -i eth0 $mac_address
In /etc/sudoers.d/99-maas-sudoers add the following line at the end:
maas ALL= NOPASSWD: /usr/sbin/etherwake
Enable IP forwarding on MAAS server:
sudo sysctl -w net.ipv4.ip_forward=1
iptables -A FORWARD -i <interface without internet> -o <interface with internet> -j ACCEPT
iptables -A FORWARD -i <interface with internet> -o <interface without internet> -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -t nat -A POSTROUTING -o <interface with internet> -j MASQUERADE
Include 127.0.0.1 in the list of DNS servers in /etc/resolv.conf on MAAS server.
sudo apt-get install openstack
sudo openstack-install
The above list of commands should successfully install Openstack Autopilot. You may also refer to the github issues on MAAS-JUJU-Autopilot at https://github.com/Ubuntu-Solutions-Engineering/openstack-installer
There is a single document which describes all this, it is here: https://help.ubuntu.com/lts/clouddocs/en/Intro.html
Beware that it is a bit outdated with respect to some topics as it was written two years ago.
Similar documentation exists for the autopilot installer:
