Clark Boylan 607b2db8c7 Use Jenkins Job Builder to config ci-docs job.
The existing ci-docs job is a one off job that was configured by hand.
Define the ci-docs job as a Jenkins Job Builder job using the existing
project-docs utilities.

To make the existing utilities work within the puppet repo the doc files
have been moved to doc/source, setup.cfg added to build docs in the new
dir, setup.py builds openstack-ci-puppet (instead of nova), tox now has
a venv virtualenv, and the .gitignore has been updated appropriately.

Infrastructure Systems
######################
The OpenStack CI team maintains a number of systems that are critical
to the operation of the OpenStack project. At the time of writing,
these include:
* Gerrit (review.openstack.org)
* Jenkins (jenkins.openstack.org)
* community.openstack.org
Additionally the team maintains the project sites on Launchpad and
GitHub. The following policies have been adopted to ensure the
continued and secure operation of the project.
SSH Access
**********
For any of the systems managed by the CI team, the following practices
must be observed for SSH access:
* SSH access is only permitted with SSH public/private key
authentication.
* Users must use a strong passphrase to protect their private key. A
passphrase of several words, at least one of which is not in a
dictionary is advised, or a random string of at least 16
characters.
* To mitigate the inconvenience of using a long passphrase, users may
want to use an SSH agent so that the passphrase is only requested
once per desktop session.
* Users private keys must never be stored anywhere except their own
workstation(s). In particular, they must never be stored on any
remote server.
* If users need to 'hop' from a server or bastion host to another
machine, they must not copy a private key to the intermediate
machine (see above). Instead SSH agent forwarding may be used.
However due to the potential for a compromised intermediate machine
to ask the agent to sign requests without the users knowledge, in
this case only an SSH agent that interactively prompts the user
each time a signing request (ie, ssh-agent, but not gnome-keyring)
is received should be used, and the SSH keys should be added with
the confirmation constraint ('ssh-add -c').
* The number of SSH keys that are configured to permit access to
OpenStack machines should be kept to a minimum.
* OpenStack CI machines must use puppet to centrally manage and
configure user accounts, and the SSH authorized_keys files from the
openstack-ci-puppet repository.
* SSH keys should be periodically rotated (at least once per year).
During rotation, a new key can be added to puppet for a time, and
then the old one removed. Be sure to run puppet on the backup
servers to make sure they are updated.
Backups
*******
Off-site backups are made to two servers:
* ci-backup-rs-ord.openstack.org
* ci-backup-hp-az1.openstack.org
Puppet is used to perform the initial configuration of those machines,
but to protect them from unauthorized access in case access to the
puppet git repo is compromised, it is not run in agent or in cron mode
on them. Instead, it should be manually run when changes are made
that should be applied to the backup servers.
To start backing up a server, some commands need to be run manually on
both the backup server, and the server to be backed up. On the server
to be backed up::
ssh-keygen -t rsa -f /root/.ssh/id_rsa -N ""
And then ''cat /root/.ssh/id_rsa.pub'' for use later.
On the backup servers::
sudo su -
BUPUSER=bup-<short-servername> # eg, bup-jenkins-dev
useradd -r $BUPUSER -s /bin/bash -m
cd /home/$BUPUSER
mkdir .ssh
cat >.ssh/authorized_keys
and add this to the authorized_keys file::
command="BUP_DEBUG=0 BUP_FORCE_TTY=3 bup server",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty <ssh key from earlier>
Switching back to the server to be backed up, run::
ssh $BUPUSER@ci-backup-rs-ord.openstack.org
ssh $BUPUSER@ci-backup-hp-az1.openstack.org
And verify the host key. Add the "backup" class in puppet to the server
to be backed up.
GitHub Access
*************
To ensure that code review and testing are not bypassed in the public
Git repositories, only Gerrit will be permitted to commit code to
OpenStack repositories. Because GitHub always allows project
administrators to commit code, accounts that have access to manage the
GitHub projects necessarily will have commit access to the
repositories. Therefore, to avoid inadvertent commits to the public
repositories, unique administrative-only accounts must be used to
manage the OpenStack GitHub organization and projects. These accounts
will not be used to check out or commit code for any project.
Launchpad Teams
***************
Each OpenStack project should have the following teams on Launchpad:
* foo -- contributors to project 'foo'
* foo-core -- core developers
* foo-bugs -- people interested in receieving bug reports
* foo-drivers -- people who may approve and target blueprints
The openstack-admins team should be a member of each of those teams.
