Print DNS commands when launching a node.
Still not automatic, but much less typing.

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::
|
||||
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:
|
||||
|
||||
. ~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
