Create Server
=============
Note that these instructions assume you're working from this
directory on an updated local clone of the repository on the
puppetmaster, and that your account is a member of the admin, puppet
and salt groups for access to their respective keys::
sudo adduser $(whoami) admin
sudo adduser $(whoami) puppet
sudo adduser $(whoami) 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 FLAVOR="8 GB Performance"
export FQDN=servername.openstack.org
sudo puppet cert generate $FQDN
./launch-node.py $FQDN --flavor "$FLAVOR"
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 FLAVOR="8 GB Performance"
sudo puppet cert generate $FQDN
./launch-node.py $FQDN --image "$IMAGE" --flavor "$FLAVOR" --salt
The --salt option tells the script to automatically configure and enroll
the server as a minion on the salt master.
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.
When running outside the official OpenStack CI infrastructure, you
will want to pass --server ci-puppetmaster.example.com otherwise the
new node wil try to register with ci-puppetmaster.openstack.org - and
fail hilariously.
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
