Create Server
=============
Note that these instructions assume you're working from this
directory on an updated local clone of the repository, and that
your account is a member of the puppet and salt groups for access
to their respective keys::
sudo adduser YOURUSER puppet
sudo adduser YOURUSER salt
(Remember to log out and back into your shell if you add yourself
to a group.)
To launch a node in the OpenStack CI account (production servers)::
. ~root/ci-launch/openstackci-rs-nova.sh
export FQDN=servername.openstack.org
sudo puppet cert generate $FQDN
./launch-node.py $FQDN
To launch a node in the OpenStack Jenkins account (slave nodes)::
. ~root/ci-launch/openstackjenkins-rs-nova.sh
export FQDN=slavename.slave.openstack.org
nova image-list
export IMAGE='Ubuntu 12.04 LTS (Precise Pangolin)'
nova flavor-list
export RAM=8192
sudo puppet cert generate $FQDN
./launch-node.py $FQDN --image "$IMAGE" --ram $RAM
If you are launching a replacement server, you may skip the generate
step and specify the name of an existing puppet cert (as long as the
private key is on this host).
The server name and cert names may be different and the latter can be
specified with --cert if needed (older Jenkins slave types still use
shared certs), but launch-node.py will assume they are the same unless
specified.
Manually add the hostname to DNS (the launch script does not do so
automatically). Note that this example assumes you've already
exported a relevant FQDN and sourced the appropriate API credentials
above.
Add DNS Records
===============
There are no scripts to automatically handle DNS at the moment due to
a lack of library support for the new Rackspace Cloud DNS (with IPv6).
However, the launch-node script will print the commands needed to be
run to configure DNS for a newly launched server. To see the commands
for an existing server, run:
./dns.py $FQDN
Activate Puppet Agent
=====================
If this is a Jenkins slave, Puppet configuration is applied through
an already installed cron job, so you can ignore this section. If
this is ''not'' a Jenkins slave, you'll want to log into it via SSH
and turn on the Puppet agent so it will start checking into the
master on its own. on Debian/Ubuntu::
sudo sed -i 's/^START=.*/START=yes/' /etc/default/puppet
sudo su -c 'invoke-rc.d puppet start'
...or on CentOS/Fedora/RHEL::
sudo chkconfig puppet on
sudo su -c 'service puppet start'
You should be able to tell from the Puppet Dashboard when it begins
to check in, which normally happens at 10-minute intervals.
