As discussed during the "Launch Node, Ansible and Puppet" summit session in Austin, we're making things unnecessarily hard on ourselves by insisting on having multiple servers in our inventory with the same name. In order to make server addition and replacement automation simpler, start using an ordinal suffix on server short names to differentiate them (we can still easily rely on DNS for their non-numbered convenience names).

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
|
|
and puppet groups for access to their respective keys::
|
|
|
|
sudo adduser $(whoami) admin
|
|
sudo adduser $(whoami) 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)::
|
|
|
|
export OS_CLOUD=openstackci-rax
|
|
export OS_REGION=DFW
|
|
export FLAVOR="8 GB Performance"
|
|
export FQDN=servername01.openstack.org
|
|
cd /opt/system-config/production/launch/
|
|
./launch-node.py $FQDN --flavor "$FLAVOR" \
|
|
--cloud=$OS_CLOUD --region=$OS_REGION
|
|
|
|
To launch a node in the OpenStack Jenkins account (slave nodes)::
|
|
|
|
export OS_CLOUD=openstackjenkins-rax
|
|
export OS_REGION=DFW
|
|
export FQDN=slavename01.slave.openstack.org
|
|
openstack image list
|
|
export IMAGE='Ubuntu 12.04 LTS (Precise Pangolin) (PVHVM)'
|
|
openstack flavor list
|
|
export FLAVOR="8 GB Performance"
|
|
./launch-node.py $FQDN --image "$IMAGE" --flavor "$FLAVOR" \
|
|
--cloud=$OS_CLOUD --region=$OS_REGION
|
|
|
|
Manually add the hostname to DNS (the launch script does not do so
|
|
automatically). Note that this example assumes you've already
|
|
exported a relevant FQDN and sourced the appropriate API credentials
|
|
above.
|
|
|
|
In order for Ansible to be able to send out the Puppet updates,
|
|
you also need the puppetmaster to accept the root SSH key for the
|
|
new server. So as root on the puppetmaster:
|
|
|
|
ssh root@$FQDN
|
|
|
|
Verify the fingerprint of the new server and type "yes" to accept.
|
|
Then you can log out.
|
|
|
|
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
