| 08:18:10 | reedip | rabel :https://review.openstack.org/#/c/439299/ | |
| 08:19:09 | rabel | reedip: i tried this, but it does not seem to work | |
| 08:19:26 | reedip | rabel : yes, I need to relook into this | |
| 08:20:32 | rabel | ok. feel free to add me to reviewers, if you upload more patches. :) | |
| 08:20:35 | reedip | I will take it today .. | |
| 08:20:46 | reedip | sure thing rabel ... | |
| 08:21:05 | rabel | since you already worked on the quota thing, maybe you can answer me another question | |
| 08:21:30 | reedip | rabel ... yessss | |
| 08:21:55 | rabel | the help text of argument "--default" says "Show default quotas for <project>". but isn't it the idea behind default quotas, that they don't belong to a certain project? | |
| 08:23:28 | reedip | rabel : IIUC , we can change the default quotas of a project | |
| 08:25:20 | rabel | reedip: i thought the default quotas are the quotas that are applied to a new project. what are default quotas for a project then? | |
| 08:26:17 | reedip | rabel : https://docs.openstack.org/admin-guide/cli-networking-advanced-quotas.html#configure-per-project-quotas | |
| 08:26:29 | reedip | neutron quota-default-show | |
| 08:28:49 | rabel | reedip: "neutron quota-default-show" as well as "openstack quota show --default" do work without providing a project | |
| 08:29:05 | reedip | rabel : they take the current user as the project | |
| 08:29:39 | rabel | reedip: ah, ok. | |
| 08:29:50 | rabel | reedip: but what are default quotas then? | |
| 08:30:20 | reedip | rabel : and the interesting thing may be here | |
| 08:30:21 | reedip | quota_driver = neutron.db.quota_db.DbQuotaDriver | |
| 08:30:21 | reedip | Set the quota_driver option in the /etc/neutron/neutron.conf file. | |
| 08:30:21 | reedip | Configure Networking to show per-project quotas | |
| 08:31:11 | reedip | this is the default quota driver, but any variant ( like RHOS, Canonical Openstack ) can create their own Quota drivers as well | |
| 08:32:04 | reedip | the neutron/db/quota_db.py DbQuotaDriver will have the default quotas which you want | |
| 08:33:32 | reedip | rabel as you see in the file ( neutron/db/quota/driver.py ) which is loaded up by neutron/db/quota_db.py | |
| 08:34:00 | reedip | they have created a --tenant for now, as it is possible to change default quotas per tenant in the future | |
| 08:34:20 | reedip | and that can be done by any third party in their own variant of the code :) | |
| 08:36:15 | rabel | reedip: i see the comment in the file. but i don't understand the idea behind default quotas for a project. | |
| 08:37:24 | reedip | Its like differentiating the quality of service of a cloud | |
| 08:38:17 | reedip | if a user wants to have a Gold Standard QoS, then they may have a specific default quota | |
| 08:38:40 | openstackgerrit | Rodolfo Alonso Hernandez proposed openstack/python-openstackclient master: Add "qos-policy" option to "port create" & "port set" https://review.openstack.org/419236 | |
| 08:38:59 | reedip | If they have platinum , then .... you can have better number of resources in default | |
| 08:40:15 | openstackgerrit | Reedip proposed openstack/python-openstackclient master: Add "qos-policy" option to "port create" & "port set" https://review.openstack.org/419236 | |
| 08:40:28 | reedip | ralonsoh : you forgot to add yourself as the author ^^ | |
| 08:40:40 | ralonsoh | No, no problem | |
| 08:41:07 | ralonsoh | reedip: it was just a forgotten patch I wanted to be fixed | |
| 08:41:13 | reedip | I added you as well ralonsoh ... you are working on it right now | |
| 08:41:29 | reedip | yeah, you are working on it.... so I added you :) | |
| 08:41:46 | ralonsoh | reedip: okidoki!! | |
| 08:42:04 | rabel | reedip: in this case the customer would have one openstack-project, not? so you could just adjust the quotas for the project. | |
| 08:42:16 | rabel | i still don't understand. sorry ;) | |
| 08:42:27 | reedip | rabel : see it from a Public cloud perspective | |
| 08:42:37 | reedip | where multiple users can request for quotas | |
| 08:42:43 | reedip | something like AWS ? | |
| 08:43:04 | rabel | never worked with aws. | |
| 08:43:32 | rabel | but quotas in openstack are always project-based, right? | |
| 08:43:42 | reedip | rabel : neither did I , but I checked their business model | |
| 08:43:47 | reedip | rabel : yes | |
| 08:44:24 | rabel | reedip: so one project has one set of quotas. | |
| 08:44:29 | reedip | rabel : yes | |
| 08:44:54 | rabel | reedip: and additionally you have one cloud-wide default set of quotas, which is applied when a new project is created. | |
| 08:45:40 | rabel | reedip: or wait | |
| 08:45:55 | reedip | rabel : thats the thing ... you can also have a default quota for a tenant | |
| 08:46:43 | rabel | reedip: and when this is used? when i create a new tenant with --parent to that other tenant? | |
| 08:50:45 | RuiChen | dtroyer: stevemar hi, I'm drafting new commands to add network interface for a server, I have two object name "interface" and "nic" now, which one you favor? the command looks like: server add interface <server> [--network | --port] | |
| 09:00:11 | rabel | reedip: and also in this context: i do not understand, what a quota class is :D | |
| 09:00:39 | reedip | sorry , in another meeting rabel :) | |
| 09:00:46 | reedip | will be back in sometime | |
| 09:00:53 | rabel | reedip: np | |
| 09:00:57 | rabel | reedip: and thank you! | |
| 09:18:53 | reedip | rabel : hi | |
| 09:19:29 | rabel | reedip: welcome back :) | |
| 09:19:36 | reedip | currently there is no discrimination between tenants for default quotas in vanilla flavor of Openstack | |
| 09:19:52 | reedip | but it can be done..... | |
| 09:19:57 | reedip | quota class in SDK ? | |
| 09:22:16 | rabel | yes, i think so | |
| 09:22:35 | rabel | reedip: i have seen it in the openstackclient | |
| 09:22:44 | rabel | p.e. openstack quota set --class | |
| 09:23:00 | reedip | ohh that ? its similar to the project attribute | |
| 09:23:17 | reedip | but I am also confused a bit about its implementation, IMHO | |
| 09:24:03 | rabel | what i already found out: you can use this to set default quotas, by using --class default | |
| 09:24:33 | reedip | is it ? :D | |
| 09:24:44 | rabel | yes :D | |
| 09:25:57 | rabel | while "openstack quota set default" without --class does not work. i think it probably tries to set quotas for a project called "default". but it doesn't fail either, it just does not have the desired outcome ;) | |
| 09:27:44 | reedip | rabel whoa... wait ! | |
| 09:28:51 | reedip | rabel : okay, I see your point | |
| 09:29:08 | reedip | So default is type of a Class | |
| 09:29:15 | reedip | and we can create more classes | |
| 09:29:35 | reedip | and set quotas as per classes on the tenants (??) | |
| 09:30:37 | rabel | that would be reasonable, but i think the last point is not right. because you can only either specify a project or a class (at least with openstackclient) | |
| 09:31:10 | rabel | actually i get the feeling, that the whole quota concept has some weaknesses ;) | |
| 09:35:58 | reedip | rabel thats y I had the ?? in my understanding | |
| 09:37:39 | rabel | reedip: do you know who could clarify this? | |
| 09:38:03 | reedip | rabel : as of now, I am not sure myself.. I am investigating your point | |
| 09:38:37 | rabel | reedip: k, thank you | |
| 09:39:40 | reedip | rabel : well , the openstacksdk states that network/v2/quota.py QuotaDefault should be picked up when setting the default quota | |
| 09:40:48 | reedip | rabel : interesting point is that --class only stores True or False :D | |
| 09:41:18 | reedip | rabel : python-openstackclient/openstackclient/common/quota.py | |
| 09:41:27 | reedip | Line#276 | |
| 09:42:43 | reedip | and for network , it should fail ..... ??? !!! | |
| 09:42:51 | rabel | reedip: yes, the class is the positional argument instead of project in this case | |
| 09:43:09 | reedip | Line #330 states that it ignores the Quota class for networks :D | |
| 09:43:22 | rabel | reedip: you're right | |
| 09:43:25 | rabel | :D | |
| 09:44:56 | reedip | rabel : so ... we need to find how the quota_classes for compute client and volume client are to be done | |
| 09:45:55 | reedip | but cant do anything about network :) | |
| 09:47:02 | reedip | leaving ... catch u in 2 hours , I guess | |
| 09:47:37 | rabel | kk, cu | |
| 09:47:46 | rabel | i'll have a look at nova | |
| 11:46:07 | rabel | someone could have a loot at https://review.openstack.org/#/c/444924/ ? it is without review for a week now | |
