hi,

We are organising a hack session to try and build, test and deliver a set of CentOS-5/6 32bit/64bit images usable by various onpremise cloud setups. This email aims to give everyone an overview of what to expect on the day, so we can jump right in on the day and get productive. This is a bit of a wordy email, so feel free to skip details - I will have most of the important stuff on paper to hand out on the day as well.

The Hack session is expected to start just after lunch, and will run through to the end of the day ( ~ 17:30 );

On the day, I will have a local Wifi network with SSID DojoHackathon running at the time, everyone wanting to participate will need to get onto that. dhcp on the network will hand out 172.30.30.100 - 250 IP's. There is a gateway on .1 that will NAT requests to the upstream internet ( but I'm told its slow, so dont rely on it being there ). If anyone needs content to pull, please let either me or Johnny know, we will mirror it down before the event and make sure its on the mirror host on the network at the time. We are going to have : - CentOS 5/6 on both 32/64 bit x86 - EPEL 5/6 - EPEL-Testing 5/6

Various people representing projects have offered to bring pre-setup cloud infra on their laptops, thanks for that. Lets try and target everyone of those on the day. So far the list is : - OpenNebula - CloudStack - OpenStack ( the HPCloud edition ) - OpenStack ( the RDO edition )

A rather basic idea of what to expect in terms of infra/network on the day : http://bit.ly/1ffXr4G ; Workflow anticipated:

- git.centos.org ( hosted locally ) will have the git repos that host kickstarts and metadata files that have some info around the kickstarts.

- anyone can clone the git repos ( I will make sure its pretty clear as to what repo to get for what task, ideally there will only be one git repo with all the kickstarts ).

- make changes / edits / push back to git.centos.org ( please ensure git user.name and user.email is sane )

- git post-recv triggers kick off the actual image builds on the image-builder node, which will then push the resulting file to cloud.centos.org ( both image-builder and cloud.centos.org mirrors will be hosted locally ).

- cloud images from cloud.centos.org can then be downloaded and instantiated on the cloud infra people are running;

- once satisfied that the image does everything that is 'required', git clone the t_functional repo, and run the test suite. PASS on that would indicate them that the image is good to ship. For the day, we will trim the test suite down to just the basic stuff that runs in 10 min or less.

- Indicate pass with a comment in the metadata file and git commit which starts with 'RELEASEABLE ', git push.

rinse & repeat for 32bit and 64bit.

Worth noting here that the reason i have all the various components setup to work with real world urls ( faked by dnsmasq on the .1 machine ) is that post hackathon the exact same infra will go live on the same urls. With one major change : we will have little or no ACL's fon the git repos at the hackathon to make live easier and encourage participation. Post Hackathon, we'll need to establish a mechanism for people to request commit access.

If we still have time at the end of the day, we can shoot to deliver something that works for vmware, ovirt and docker. I am still waiting to hear back from the Eucalyptus guys if someone from their side is going to be at the hack session.

please note: all kickstarst and images will need to only consume content hosted in mirror.centos.org and epel ( or if you need something else, let us know before Wed 29th ).

See you there,
