Infrastructure private cloud
Note -- there was a meeting held describing the current state of the cloud on March 25, 2014. The logs of that are more up to date than this wiki page.
Fedora Infrastructure is running 2 private cloudlets for various infrastructure projects. One of these is the primary or 'production' cloud, the other is used for newer versions and testing different setups or software tech. Currently the primary cloud is running openstack folsom, the other is testing openstack icehouse. We are in the process of migrating to the new icehouse based cloud now.
In 2012 we setup 2 sets of machines for 2 cloudlets. We tested various cloud software on these cloudlets at various times. Finally a primary cloudlet was established with openstack folsom. In 2014 and 2015 we setup a new cloud using ansible playbooks to do a repeatable and maintainable setup.
We have things setup in 2 cloudlets to allow us to serve existing cloud needs, while still having the ability to test new software and tech. From time to time we may migrate uses from one to the other as a newer version or kind of setup is determined to meet our production needs more closely.
Current setup (as of 2014-03-25) is described in #fedora-classroom: http://meetbot.fedoraproject.org/fedora-classroom/2014-03-25/infrastructure-private-cloud-class.2014-03-25-18.00.log.html
old cloudlet (folsom, being migrated away from):
- fed-cloud01, fed-cloud03, fed-cloud04, fed-cloud05, fed-cloud06, fed-cloud07, fed-cloud08 are all compute nodes in this cloud.
- fed-cloud02 is the main controller node.
new cloudlet (icehouse, being migrated to):
- fed-cloud09 is the main controller node
- fed-cloud10,11,12,13,14,15 are compute nodes.
Setup / deployment
This hardware is setup on the 'edge' of the network and not connected to the rest of Fedora Infrastructure except via external networks. This allows us to us external ip's and make sure the cloud instance doesn't have access to anything in the regular Fedora Infrastructure. Storage will be on the local servers.
We have 15 physical servers total. Currently 8 of them are in the 'production/old/folsom' cloudlet, and 7 are in the new icehouse cloudlet. As we migrate we will move more nodes to the icehouse cloudlet.
Users or groups that need rare one off images can simply request one via a infrastructure ticket.
Users or groups that often need instances may be granted accounts to spin up and down their own images.
Instances may be rebooted at any time. Save your data off often.
Persistent storage may be available as seperate volumes. Data retention and Quotas may be imposed on this data.
Instances are assist in furthering the work related to the Fedora Project. Please don't use them for unrelated activities.
We reserve the right to shutdown, delete or revoke access to any instances at any time for any reason.
We will provide fedora and centos and rhel images.
If you need to add images, please name them the same as their filename. Ie, "Fedora 22 Beta TC 2" is fine, please don't use 'test image' as we have no idea what it might be.
- The copr buildsystem is housed entirely in the Fedora Infrastructure Private cloud.
- jenkins. Fedora infrastructure provides a jenkins instance to run tests on some open source projects.
- Many Infrastructure dev instances are housed in the Fedora Infrastructure private cloud.
- The twisted project runs some buildbot tests.
ssh access to the bare nodes will be for sysadmin-cloud and possibly fi-apprentice (with no sudo).
With the move to the new icehouse cloud, we will be reserving the right to update and reboot the cloud when and as needed. We will schedule these outages as we do for any outage and will spin back up any persistent cloud instances we have in our ansible inventory after the outage is over. It's up to owners of any other instances to spin up new versions of them after the outage and make sure all updates are applied.
