OpenStack Tour de Force
Florian's tutorial at OSCON 2013. This page contains important information for tutorial attendees, and will be updated iteratively in the run-up to the conference.
Please note: If you are a tutorial attendee, you might want to subscribe to this page (scroll to the bottom and check Subscribe to → This page, then hit Update). That way, you will get a quick email any time this post is updated, or someone adds a comment. You must be logged in to subscribe.
All the important basic details for this tutorial are on the OSCON website. Please make sure you take a peek.
Expect the tutorial to be crowded. There were over 130 registrations two weeks prior to OSCON, and it's safe to assume that the number will still go up. You might want to be there early, too, to make sure you get your preferred seat.
The VirtualBox images are available via Ubuntu One. It would be great if you could bring these with you to the tutorial, preferably installed, all fired up and ready to go. There are two images:
- A Puppet master box, which also doubles as a pre-populated proxy so we don't hit the network with any package installations, openstack-puppet.ova (approx. 600M).
- One template OpenStack node machine, openstack.ova (approx. 300M).
(In addition, there's also an MD5SUMS file).
You'll need only one incarnation of the Puppet master, but three of the OpenStack nodes.
The OpenStack nodes also rely on the availability of a total of 3 host-only networks for internal communications. You'll need to configure them in VirtualBox.
To create the host-only networks, you can either open the VirtualBox Manager, go to File → Preferences and then the Network tab, and create vboxnet0, vboxnet1 and vboxnet2. Or you can run the following steps using the VBoxManage utility from a terminal:
$ VBoxManage hostonlyif create 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Interface 'vboxnet0' was successfully created $ VBoxManage hostonlyif ipconfig vboxnet0 \ --ip 192.168.122.1 --netmask 255.255.255.0 $ VBoxManage hostonlyif create 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Interface 'vboxnet1' was successfully created $ VBoxManage hostonlyif ipconfig vboxnet1 \ --ip 192.168.133.1 --netmask 255.255.255.0 $ VBoxManage hostonlyif create 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Interface 'vboxnet2' was successfully created $ VBoxManage hostonlyif ipconfig vboxnet2 \ --ip 192.168.144.1 --netmask 255.255.255.0
Then, when you import the appliances into your VirtualBox, do make sure that you reinitialize the machines' MAC addresses. Then,
- Boot up each OpenStack node
- Log in as
rootwith the password
./fixup-hostcharlie, respectively, on the three OpenStack nodes. Then reboot them and you're good to go. No changes are necessary to the Puppet node.
RAM on the machines is deliberately configured on the low side, such as to make the VMs run on laptops without copious amounts of memory. If your laptop does have a good amount of memory, turning RAM up to 2G for the nodes
bob won't hurt.
If you turn up early for the tutorial (around 1pm), you can still grab a USB key containing the VM images from Florian.
The tutorial is in room Portland 255, on the upper level next to the grand ballroom where Ignite and the OSCON keynotes take place.
