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 group for access to the
puppet keys::
sudo adduser YOURUSER puppet
(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
export CERT=slavetype.slave.openstack.org
nova image-list
export IMAGE='Ubuntu 12.10 (Quantal Quetzal)'
nova flavor-list
export RAM=2048
sudo puppet cert generate $CERT
./launch-node.py $FQDN --cert $CERT.pem --image "$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 (as in the Jenkins
slave example), 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 handle DNS at the moment due to a lack of
library support for the new Rackspace Cloud DNS (with IPv6). To
manually update DNS, you will need the hostname, v4 and v6 addresses
of the host, as well as the UUID (these can all be found by running
the ''nova list'' command). The environment variables used in the
URL should be satisfied by sourcing the "openstackci-rs-nova.sh"
script (or jenkins, as appropriate). Also the above launch script
should output some environment variable assignments for UUID, IPV4
and IPV6 you can cut and paste as needed, or you can fill them in
yourself::
. ~root/rackdns-venv/bin/activate
UUID=01234567-89ab-cdef-fedc-ba9876543210
IPV4=123.45.67.89
IPV6=fedc:ba98:7654:3210:dead:beef:cafe:feed
rackdns rdns-create --name $FQDN --data "$IPV6" --server-href https://$os_region_name.servers.api.rackspacecloud.com/v2/$OS_TENANT_NAME/servers/"$UUID" --ttl 300
rackdns rdns-create --name $FQDN --data "$IPV4" --server-href https://$os_region_name.servers.api.rackspacecloud.com/v2/$OS_TENANT_NAME/servers/"$UUID" --ttl 300
. ~root/ci-launch/openstack-rs-nova.sh
rackdns record-create --name $FQDN --type AAAA --data "$IPV6" --ttl 300 openstack.org
rackdns record-create --name $FQDN --type A --data "$IPV4" --ttl 300 openstack.org
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::
sudo sed -i 's/^START=.*/START=yes/' /etc/default/puppet
sudo invoke-rc.d 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.
