This page is obsolete and should be removed by 2021-06. There is currently no Fedora Infrastructure Cloud and no plans to bring it back. Currently Fedora Infrastructure relies on gifted cloud units from Amazon for this.

Background

Fedora Infrastructure is running a private cloud infrastructure for various infrastructure and community projects. This infrastructure is currently running RHOSP 5 (Red Hat Open Stack Platform 5).

Two Cloudlets

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 primary setup

fed-cloud09 is the main controller node
fed-cloud03,04,05,06,07,08,10,11,12,13,14,15 and fed-cloud-ppc02 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 17 physical servers total. Currently 14 of them are in production, and 3 are being used for testing purposes by the infrastructure team.

Storage is provided by 2 dell equalogics boxes (one with ~20TB space, the other with ~10TB)

The current setup has only 1 controller node so outages can and will occur when upgrades are being done, etc.

Nodes in this cloud use the 'fedorainfracloud.org' domain in most cases (with some few exceptions).

x86_64 and ppc64 and ppc64le instances are provided by the current cloud.

Upcoming plans

As many of the existing hardware boxes are reaching end of life/support, we have ordered some new hardware in Q2 of 2017. We plan to setup RHOSP10 (or later) on this new hardware and then recreate instances in this new cloud and retire the old one. This is planned for mid/late 2017. This new install should allow us to setup 2 head nodes with HA so we can do upgrades or the like without much in the way of outages. Additionally we hope to add armv7 and aarch64 support via openstack ironic.

Policies

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.

Images

We will provide fedora, 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.

Major users

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.

Fedora magazine and community blogs are hosted here.

The twisted project runs some buildbot tests.

hardware access

ssh access to the bare nodes will be for sysadmin-cloud and possibly fi-apprentice (with no sudo).

maint windows

We are 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.

Contact / more info

Please contact the #fedora-admin channel or the fedora infrastructure list for any issues or questions around our private cloud.

-= Use cases =
+= Current primary setup =
-== Doesn't need persistent storage ==
+* fed-cloud09 is the main controller node
+* fed-cloud03,04,05,06,07,08,10,11,12,13,14,15 and fed-cloud-ppc02 are compute nodes.
-* Fedora QA may use instances with it's AutoQA setup. Instances would be created, tests run and destroyed. It's unknown how many instances we would need here.
+= Setup / deployment =
-* Coprs uses our cloud for a frontend, backend and builders. Builds are submitted to the frontend, the backend processes them and creates builder instances to build and then terminates build instances when complete.
+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.
-* Mass rebuilds of Fedora packages. This could be done for testing a new global rpm/package change, or to discover FTBFS (Fails to build from source) packages. This would use as many builders as we could easily spin up to reduce time for building all 10,000+ Fedora packages. Could use the chainbuilding setup as above as a scaffolding. Additionally, extra builder instances could be potentially used by the official build system during mass rebuilds to reduce rebuild time.
-* Docs folks need to generate i18n versions of docs. This would require an instance, tools and a script running. Then data is synced off and the instance could be destroyed.
-== Needs persistent storage, but possibly can use a /mnt ed volume ==
-* Test instances may be used for testing new tech or applications as a proof of concept before persuing a RFR.
-== Needs persistent storage and snapshots ==
-* Infrastructure Development hosts have been moved to this cloud. These instances could possibly be 'on demand' when development needs to take place. Currently we have about 8 development instances many on cloud. The rest should be migrated soon.
+We have 17 physical servers total. Currently 14 of them are in production, and 3 are being used for testing purposes by the infrastructure team.
-* We may want to move some of our one-off instances that are outside phx2 into the cloud for easier management. Things like keyservers, unbound instances, listservers or hosted resources. This is not yet planned for.
+Storage is provided by 2 dell equalogics boxes (one with ~20TB space, the other with ~10TB)
-Further down the road:
+The current setup has only 1 controller node so outages can and will occur when upgrades are being done, etc.
-* Instances for qa/packagers to test new packages or track down bugs.
+Nodes in this cloud use the 'fedorainfracloud.org' domain in most cases (with some few exceptions).
-* Instances for demos or events to show off Fedora.

 = Images =
-We should customize available images for the above use cases:
+We will provide fedora, centos and rhel images.
-== All images ==
-Currently for Fedora we are using the produced cloud images. For RHEL we are using a similar minimal instance image.
-== Infrastructure Dev Instances ==
-Based on rhel6 image.
-Should contain:
-mod_wsgi, httpd, git-core, puppet, persistent volume mounted on /srv
-== QA images ==
-TBD
-== Builder Images ==
-For mockchain/kopers use. Should be limited to 24 hours.
-= Using ansible with the cloud =
-TBD: fill in with info on how to make transient or persistent instances via ansible on lockbox01.
-= Moving to "production" =
-This section is a checklist of things we need to do before we can consider either of the cloudlets "production". Once we move to production mode on them we will move to scheduling outages, try and keep instances running smoothly and just perform upgrades and maint on the cloudlets. We want to make sure before we do this that things are stable and processes are ready for users.
-* SOP needs to be written for creating images. (whats in them, update policy, ssh keys policy, etc)
-** We can reuse the Fedora cloud images for Fedora
-** We still need to determine a 'standard' RHEL6 image.
-** ssh keys should be added for root for sysadmin-main and sysadmin-cloud?
-* <strike>Decide who gets a login to manage instances, and who can just request instances be made for them. </strike>
-** Normal use cases have instances created by ansible. If further access is needed it's granted on case by case.
-** Down the road we may want to integrate fas somehow, but not now.
-* <strike>SOP on making an instance for a requestor (via infra ticket?)</strike> yes, via ticket.
-** Write an instance-setup script tools to fetch from fas user ssh key based on the given fas login so that user can receive an email once instance is created and log in.
-** Do all instance creation in ansible?
-* Decide on time limits or other resource limits per account/tennat. Setup initial accounts/tenants.
-* OpenStack cloudlet needs ansible playbooks written to install/configure it.
-* <strike>OpenStack needs folsom testing performed. </stike> folsom installed now.
-* <strike>OpenStack needs vlan testing performed. </strike> vlans in use.
-* <strike>OpenStack needs non glusterfs testing done. </strike> current install has base fs.
-* <strike>Do we need to decide between euca and openstack? When?</strike> For now we are going to do both.
-* We need monitoring added. nagios? Controllers down, nodes down, capacity issues, etc.
+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.
-** run a nagios persistent image in either cloudlet and monitor the other?
-* We need reporting added. Note when instances are made, etc. Either logging to log02, or some seperate report for cloud-sysadmins. Possibly some export from the software about cpu/mem/disk, etc.
+= Major users =
-** Could possibly be done at ansible creation time or via a gather script
-** email from ansible script is done now, still need reporting of non ansible instances.
-* <strike>Need to determine who has access to physical cloud machines. Repurpose sysadmin-cloud, setup fas and sudo?</strike>
+* The copr buildsystem is housed entirely in the Fedora Infrastructure Private cloud.
-** if we (and we should) add fas, why not configure it to only create shell account for people who is admin or sponsor from sysadmin-cloud. Which bring us back to 2nd point where approved people from sysadmin-cloud could have access to request instances to be made.
-** shell access to the physical cloudlet machines doesn't grant you any access to the cloud software directly.
-** sysadmin-cloud will have access to the compute and head nodes, but no special access to the cloud instances.
-* <strike>Setup group that can run ansible against physical cloud machines for updates, etc. (see above question too)</strike>
+* jenkins. Fedora infrastructure provides a jenkins instance to run tests on some open source projects.
-* <strike>Consider a re-occuring maint window for reboots/updates... ie, tell everyone that every month we have a window to do so, save work before then?</strike>
+* Many Infrastructure dev instances are housed in the Fedora Infrastructure private cloud.
-** will just schedule these as needed.
-* Figure out how to handle dns. Should we setup some kind of dyndns? Should we just leave it with generic dns? Should we ask for control of reverse dns?
+* Fedora magazine and community blogs are hosted here.
-** We have asked for control of reverse dns.
-* How do we back these systems up and what should we actually be backing up.
+* The twisted project runs some buildbot tests.
-** At this point I'd say we don't back up and note to users to always back up their data often.
-* <strike>Figure out how to make some system be or seem to be persistent</strike> This can be done in ansible repo on lockbox
+= hardware access =
-* store more metadata per instance created so we can track who/when/where/what (requires tags in eucalyptus 3.3 - not existent as of now)
+ssh access to the bare nodes will be for sysadmin-cloud and possibly fi-apprentice (with no sudo).
-= Post-Production/2.0 =
+= maint windows =
-* backup 'subscription' service - so users of the cloud can request that backups be performed on their instances and how they should happen

-* openid/fas integration might be nice.
+= Contact / more info =
-* increase capacity and gather more use cases.
