My presentation slides from the #HappyHackingDay 2014 at @HAAGAHELIAamk. The story of Harry and Hermione hackers on their way to rule the cloud magic. The event was for hackers, and my topic was about pointing ways and tools to hack in the cloudy world. There is many places within the cloud engines and tools around cloud to hack. Plenty of interesting open source projects for hackers to find, and perfect their skills. Harry the hacker fell on a keyboard as he was a baby, hitting his forehead to letter 'H'. That left a scar into his forehead. He is eager to do rush into action, and he is very skilled. He trains his skills by practice, and listening to elder open source community members. Hermione is extremely talented hacker as well. She has more interest on how things are done, learning continuously more and more. She spends also lot of her time on reading and writing community docs, active member on forums, and knows lot of spells. Bad guys in the story are... well, bad guys. Any similarities to other characters is pure co-incidense ;) Keywords are: open source, openstack, heat, puppet, chef, automation, oz, horizon, cloud-init

Hey, I found a secret map, what is it?

17. 2013-03-12 Ilkka Tengvall / Cybercom Finland
I know, I've seen it.
It's OpenStack architecture
description!
I recall it's all documented here:
http://docs.openstack.org
Along with all the installation,
operational and API documentation.

18. 2013-03-12 Ilkka Tengvall / Cybercom Finland
Go check the OpenStack pages
● Plenty of documentation
● Community page lists different ways to
get involved
● All blueprints and decisions are open
● There is plenty of projects to get
hacking in different areas of cloud

19. 2013-03-12 Ilkka Tengvall / Cybercom Finland
Several ways to install
● Development installations for the cloud
● $ git clone https://github.com/openstack-dev/devstack.git
● $ cd devstack; ./stack.sh
● The Red Hat family way
● $ sudo yum install -y openstack-packstack
● $ sudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
● All major OS install instructions are in the
openstack docs
● Check puppet for openstack!

I've been training the beasts at Puppet
Forge, feeding them with Chef recipes
and using cloud-init to multiply them!
