[openstack-dev] [kolla][kolla-k8s] Installation in ubuntu 14.04
Hi All, I am trying to install openstack containers using kolla-k8s. I am following below link: https://docs.openstack.org/kolla-kubernetes/latest/deployment-guide.html# As per link, its only supported/validated for ubuntu 16.04. Please let me know if any version 0.6/0.5.0.4 is supported for ubuntu 14.04. Its not mentioned in release notes. Also how to determine upfront which openstack version does it support.

Re: [openstack-dev] [Openstack] [celery][taskflow] Reg. celery and task-flow
Hi Joshua, Thanks for the response. As you mentioned, I went through below which has taskflow as celery front end: https://etherpad.openstack.org/p/TaskFlowWorkerBasedEngine https://blueprints.launchpad.net/taskflow/+spec/distributed-celery I guess if we have a job = task1 + task2 ; if we execute them through a taskflow parallel pattern, they will be executed in parallel. Just curious to know that since this threading is built on eventlets/green threads/python threads they will be affected by GIL and we may not utilize multi-core capability of our systems. It seems in celery, we can have these tasks run as multiple processes so that they are not affected by GIL. Please correct me if my understanding is wrong ??

[openstack-dev] [celery][taskflow] Reg. celery and task-flow
Hi All, Please let me know whether celery is replacement for taskflow. As per my understanding, task-flow can break jobs into tasks and execute them. >From celery wiki, it also does almost similar behaviour. I guess in most of openstack components taskflow is widely used. Any places where its being replaced with celery ??

[openstack-dev] [heat] scaling in a tenant
Hi All,
Please help me in understanding below scenario ???
I am doing manual scaling based on inputs from monitoring framework instead
of ceilometer alarms.
I launched my heat stack in a tenant using python-api bindings:
>>> tenant_id = 'Tenant-A'
>>> heat_url = 'http://heat.example.org:8004/v1/%s' % tenant_id
>>> auth_token = 'user-A-in-Tenant-A auth-token'
>>> from heatclient.client import Client
>>> heat = Client('1', endpoint=heat_url, token=auth_token)
If I need to scale VM's belonging to this tenant, can I use tenant_id =
'Tenant-A' and auth_token corresponding to admin Tenant who has role access
in Tenant-A.
Because through monitoring framework, i can have admin details and no
tenant context ??
Thanks
Eswar

[openstack-dev] [keystone] Auth-token expiration time
Hi All, I have an application which does some HEAT transactions of creating stack,polling for it and updating stack in a loop. In my setup, /etc/keystone/keystone.conf has below settings: expiration=3600 But my transaction loop takes more than 1 hr and AUTH token is expired in between and I am getting : Exception in heat start task for stack jsm-e08dceac-71fe-48e8-817e-93ec78881827 of network service e08dceac-71fe-48e8-817e-93ec78881827 due to ERROR: Authentication failed.Please try again with option --include-password or export HEAT_INCLUDE_PASSWORD=1 Is there any means of making the auth-token not getting expired instead of changing expiration time in keystone conf ??

[openstack-dev] [heat] perfomance benchmark metrics of heat-api

[openstack-dev] taskflow usage
Hi All, I am looking into taskflow userguide and examples. http://www.giantflyingsaucer.com/blog/?p=4896 Can anyone please help me how the job/job-board is related to task and flows. I understood atom is similar to a abstract interface and taskflow is an atom that has execute()/revert() methods and a flow is structure that links these tasks. Is it that a job is broken into tasks?? Can a job be broken into set of tasks???
