Steve,
Thanks for your kind advice.
I'm trying to go first through the quick start for magnum with devstack on
ubuntu and I'm also
following this guide to create a bay with 2 nodes:
http://git.openstack.org/cgit/openstack/magnum/tree/doc/source/dev/dev-quickstart.rst
I got somehow far, but by running this step to run the service tp provide a
discoverable endpoint for the redis sentinels in the cluster:
magnum service-create --manifest ./redis-sentinel-service.yaml --bay testbay
I'm getting:
ERROR: Invalid resource state. (HTTP 409)
In the console, I see:
2015-05-10 22:19:44.010 4967 INFO oslo_messaging._drivers.impl_rabbit
[-] Connected to AMQP server on 127.0.0.1:5672
2015-05-10 22:19:44.050 4967 WARNING wsme.api [-] Client-side error:
Invalid resource state.
127.0.0.1 - - [10/May/2015 22:19:44] "POST /v1/rcs HTTP/1.1" 409 115
The testbay is running with 2 nodes properly:
ubuntu at magnum:~/kubernetes/examples/redis$ magnum bay-list
| 4fa480a7-2d96-4a3e-876b-1c59d67257d6 | testbay | 2 |
CREATE_COMPLETE |
Any ideas, where I could dig for the problem?
By the way after running "magnum pod-create .." the status shows "failed"
ubuntu at magnum:~/kubernetes/examples/redis/v1beta3$ magnum pod-create
--manifest ./redis-master.yaml --bay testbay
+--------------+---------------------------------------------------------------------+
| Property | Value
|
+--------------+---------------------------------------------------------------------+
| status | failed
|
And the pod-list shows:
ubuntu at magnum:~$ magnum pod-list
+--------------------------------------+--------------+
| uuid | name |
+--------------------------------------+--------------+
| 8d6977c1-a88f-45ee-be6c-fd869874c588 | redis-master |
I tried also to set the status to running in the pod database table,
but it didn't help.
P.S.: I tried also to run the whole thing on fedora 21 with devstack,
but I got more problems as on Ubuntu.
Many thanks in advance for your help!
