Thanks for the explanation. But I am still a little confused about
the point of the templates. Having two implementations, one simple
and one less simple, is not simpler than having only one. You still
need to user the CLI for user, roles, etc. so having a different
mechanism for endpoints does not seem simple. With regard to
performance, won't these endpoint values be changing infrequently
and so any reasonable caching strategy would give good performance?
Or am I missing something?<br>

<p class="MsoNormal"><span style="">Hi
there !<br>
<br>
I wanted to give a try to the
milestone-proposed branch of keystone
and<br>
got stuck quite fast.<br>
<br>
I am not sure if i hit a bug and
should report it, or if i'm doing<br>
something wrong.<br>
<br>
With previous version of keystone
(read packaged on ubuntu precise), i<br>
was able to create endpoint the
following way once keystone has been<br>
installed:<br>
<br>
1) setting some env variables:<br>
export KEYSTONE_IP=192.168.122.102 #
IP of your keystone API server<br>
export SERVICE_ENDPOINT=<a
moz-do-not-send="true"
href="http://$KEYSTONE_IP:35357/v2.0/"
target="_blank">http://$KEYSTONE_IP:35357/v2.0/</a><br>
export SERVICE_TOKEN=999888777666<br>
export NOVA_PUBLIC_URL="<a
moz-do-not-send="true"
href="http://$NOVA_IP:8774/v1.1/%%28tenant_id%29s"
target="_blank">http://$NOVA_IP:8774/v1.1/%(tenant_id)s</a>"<br>
export NOVA_ADMIN_URL=$NOVA_PUBLIC_URL<br>
export
NOVA_INTERNAL_URL=$NOVA_PUBLIC_URL<br>
<br>
2) creating services:<br>
keystone service-create --name nova
--type compute --description<br>
'OpenStack Compute Service'<br>
<br>
keystone service-create --name swift
--type object-store --description<br>
'OpenStack Storage Service'<br>
<br>
keystone service-create --name glance
--type image --description<br>
'OpenStack Image Service'<br>
<br>
keystone service-create --name
keystone --type identity --description<br>
'OpenStack Identity Service'<br>
<br>
3) creating an endpoint for those
services, starting with the compute<br>
service:<br>
<br>
ID=$(keystone service-list | grep -i
compute | awk '{print $2}')<br>
<br>
<br>
keystone endpoint-create --region
RegionOne --service_id $ID --publicurl<br>
$NOVA_PUBLIC_URL --adminurl
$NOVA_ADMIN_URL --internalurl
$NOVA_INTERNAL_URL<br>
<br>
When i run this command with
milestone-proposed, i experience the
following:<br>
<br>
No handlers could be found for logger
"keystoneclient.client"<br>
The action you have requested has not
been implemented. (HTTP 501)<br>
<br>
<br>
Strangely enough, i experience a
similar error message when running a<br>
simple "keystone endpoint-list"
whereas command such as "keystone<br>
user-list" works all right.<br>
<br>
<br>
here is what i have in the keystone
logs when trying "endpoint-list":<br>

<br>
I try to add some debug in<br>
keystone.catalog.core.EndpointController.get_endpoints()
method:<br>
<br>
def get_endpoints(self, context):<br>
LOG.debug("PLOP
get_endpoints")<br>
self.assert_admin(context)<br>
LOG.debug("PLOP STILL
HERE") # <= LAST DEBUG LINE<br>
endpoint_list =
self.catalog_api.list_endpoints(context)<br>
LOG.debug("SO, how does
endpoint_list looks like ?")<br>
for i in endpoint_list:<br>
LOG.debug("PLOP: '%s'",s)<br>
endpoint_refs =
[self.catalog_api.get_endpoint(context,
e)<br>
for e in
endpoint_list]<br>
LOG.debug("PLOP THIS IS THE
END")<br>
return {'endpoints':
endpoint_refs}<br>
<br>
So, as i do not see anything after
"PLOP STILL HERE", i am assuming<br>
something is wrong in the
catalog_api.list_endpoints() method.<br>
<br>
However, i do not understand exactly
where it is implemented.<br>
catalog_api is a Manager instance,
wich seems to be a subclass of<br>
Manager() defined in
keystone/keystone/common/manager.py
but i am lost<br>
with the wrapping magic that occurs
there.<br>
<br>
So, is this a bug that i should file ?<br>
<br>
