| sudipto | hongbin, hello. | 16:50 |
|---|---|---|
| hongbin | sudipto_: hey | 17:32 |
| hongbin | sudipto: ^^ | 17:33 |
| sudipto | Are we planning to have a flavor defined for zun? | 17:33 |
| sudipto | as in container flavours. | 17:33 |
| hongbin | sudipto: maybe | 17:33 |
| hongbin | sudipto: could be discussed within the team | 17:34 |
| hongbin | You want it? | 17:34 |
| *** manikanta_tadi has quit IRC | 17:34 | |
| sudipto | the resource management is quite different from a virtual machine - however things like cpu-shares/memory-limits could be provided as a flavor - but i have to check if a default flavour is really needed in this case. | 17:35 |
| sudipto | it should be possible to boot a container without such limits too however. But given we discussed briefly about multi-tenancy the other day - it would be interesting to figure out. | 17:35 |
| hongbin | Yes, I agree that the best practice is always specify the limits | 17:36 |
| hongbin | Unlimited container is too risky | 17:37 |
| sudipto | ok and the volume limits in docker is also pretty dicey | 17:37 |
| hongbin | volume limit? | 17:37 |
| sudipto | as in how much disk a docker container is allowed to write on. | 17:38 |
| hongbin | I see | 17:38 |
| hongbin | How to specific a disk limit? | 17:39 |
| hongbin | (sorry, I don't know that) | 17:39 |
| sudipto | yeah it's not robust | 17:39 |
| sudipto | https://github.com/docker/docker/issues/3804 | 17:39 |
| hongbin | I see | 17:40 |
| hongbin | We can enforce a default limits | 17:40 |
| hongbin | For example, if users don't specify a memory limit, set it as 512M | 17:41 |
| hongbin | something like that | 17:41 |
| hongbin | Another option is to make this attribute mandatory, | 17:42 |
| hongbin | Like Nova I guess, require a flavor | 17:42 |
| hongbin | Could discuss this further at the next team meeting | 17:42 |
| hongbin | sudipto: A questin for you though | 17:43 |
| sudipto | yeah ok | 17:43 |
| hongbin | sudipto: Currently, we don't support interactive mode (i.e. docker run -it ubuntu bash) | 17:44 |
| hongbin | sudipto: Do you think if it is a good idea to support that | 17:44 |
| sudipto | I will ask a related question - should we allow the users to exec into the containers? | 17:45 |
| hongbin | Yes, I wonder it as well | 17:45 |
| hongbin | If a user is from docker, he/she possible want this feature | 17:46 |
| hongbin | If a user is from Nova, maybe not | 17:46 |
| hongbin | Another thing is how to implement it | 17:46 |
| sudipto | yeah - i will do some research around this and tomorrow - we can discuss... | 17:47 |
| hongbin | The implementation would be something like open a socket and don't close it until a signal | 17:47 |
| hongbin | sure | 17:47 |
| hongbin | Well, it is just brainstroming | 17:47 |
| sudipto | yeah - you mean hyper like thing | 17:47 |
| sudipto | yeah | 17:47 |
| hongbin | Not sure about hyper | 17:47 |
| sudipto | hyper uses sockets to interact with containers running inside the virtual machines...however let me try to think around this problem. | 17:48 |
| hongbin | k | 17:48 |
| sudipto | I tried to install zun inside a devstack container today - but failed | 17:48 |
| hongbin | .... | 17:48 |
| sudipto | i will try again tomorrow. there seems to some problems. | 17:49 |
| hongbin | kk | 17:49 |
| sudipto | Basically - i was trying to run devstack inside a docker container on my mac and then wanted to get zun installed on it. | 17:49 |
| hongbin | I see | 17:49 |
| hongbin | Let me know if anything I can help | 17:50 |
| sudipto | basically - it's failing with errors, then i go correct them - then again it fails. At the moment this seems to complain about some kernel modules for writing iptables rules. | 17:53 |
| sudipto | I will share the DockerFile with you tomorrow, maybe you could try as well. | 17:53 |
| hongbin | sure | 17:53 |
| sudipto | hongbin, it should be possible to run zun right now with just keystone right? | 17:56 |
| hongbin | It should be fine | 17:56 |
| hongbin | Let's me double check | 17:57 |
| sudipto | ok... | 17:57 |
| sudipto | coz i guess we aren't using anything else...as a dependent project | 17:57 |
| hongbin | I run both Magnum and Zun at the same devstack | 17:59 |
| hongbin | So, I am not sure about that | 17:59 |
| hongbin | However, it should just work with only Keystone | 18:00 |
| sudipto | Ok. | 18:00 |
