| *** longfei_zhang has joined #openstack-kuryr | 06:52 | |
| longfei_zhang | vikasc, i couldn't understand why there is only one kuryr instance per openstack enviroment? | 06:53 |
|---|---|---|
| *** kzaitsev_ws has joined #openstack-kuryr | 06:53 | |
| longfei_zhang | i found this info "Kuryr Controller: This daemon runs usually on the same nodes where you run the Kubernetes API." | 06:54 |
| longfei_zhang | so consider this case if we have server different tenants in one openstack deployment , i think each tenant should deploy their own kuryr instance | 06:56 |
| *** tonanhngo has joined #openstack-kuryr | 07:05 | |
| *** tonanhngo has quit IRC | 07:09 | |
| kzaitsev_ws | longfei_zhang: 'server different tenants' means you have a k8s-api per tenant? | 07:14 |
| *** tonanhngo has joined #openstack-kuryr | 07:14 | |
| longfei_zhang | kzaitsev_ws, yes | 07:15 |
| longfei_zhang | per tenant can deploy their own k8s cluster | 07:16 |
| longfei_zhang | if they need it | 07:16 |
| kzaitsev_ws | longfei_zhang: well k8s-api-url is configured in kuryr.conf, so yeah if you have multiple api servers you would need multiple kuryr.confs and multiple instances of kuryr-k8s | 07:16 |
| longfei_zhang | yes, that make sense | 07:17 |
| longfei_zhang | kzaitsev_ws, i have another question , in k8s cluster if there are more than one master node , i.e. more than one k8s api server inside the same cluster, we need to deploy kuryr controller on each master node? i want to know if this is the valid case? | 07:21 |
| kzaitsev_ws | longfei_zhang: hm, not really. kuryr-k8s talks to k8s via api calls | 07:24 |
| *** aojea has joined #openstack-kuryr | 07:25 | |
| kzaitsev_ws | so if your api is behind a load balancer for example — you can probably just give that load balancer's address | 07:25 |
| longfei_zhang | yes | 07:25 |
| longfei_zhang | if i only run the kuryr on one vm and monitor the lb's address , then we might need to consider the HA of kuryr | 07:27 |
| kzaitsev_ws | I believe there is no HA at the moment though | 07:28 |
| longfei_zhang | yes | 07:29 |
| *** tonanhngo has quit IRC | 07:31 | |
| *** egonzalez has joined #openstack-kuryr | 07:37 | |
| *** gouthamr has joined #openstack-kuryr | 07:39 | |
| longfei_zhang | kzaitsev_ws, so before we have HA, say i have two k8s mater vm , i want to deploy kuryr controller to each mater vm , is this ok ? | 07:44 |
| longfei_zhang | or any negative impact? | 07:44 |
| *** dims has quit IRC | 07:45 | |
| kzaitsev_ws | I haven't tried that, but it might work. Both instances would ask for ports from neutron, but one of them would not be able to update the annotation, so it would back off/delete it's port | 07:47 |
| *** dims has joined #openstack-kuryr | 07:48 | |
| longfei_zhang | kzaitsev_ws, i have tried that , it works fine, if there are more than one master vm, only one mater vm can handle the api request, say create pod request | 07:51 |
| kzaitsev_ws | longfei_zhang: how would watch api work then? | 07:52 |
| longfei_zhang | there is no api call to other mater vm, so will not happen both instances would ask for ports from neutron | 07:52 |
| longfei_zhang | kuryr only what the local host api | 07:52 |
| longfei_zhang | kuryr only watch the local host api | 07:53 |
| kzaitsev_ws | yeah, but whouldn't the watched events propagate to all api servers? | 07:53 |
| kzaitsev_ws | say if I have m1 and m2 running kubernetes api. then start watching for pod events on m1 and then add a pod on m2 — would watcher on m1 get the creation event? | 07:59 |
| kzaitsev_ws | I believe it should | 08:00 |
| longfei_zhang | kzaitsev_ws, it's a good question, let me check this again | 08:02 |
| *** garyloug has joined #openstack-kuryr | 08:13 | |
| vikasc | longfei_zhang, multi-tenancy is not supported yet | 08:14 |
| *** salv-orl_ has joined #openstack-kuryr | 08:19 | |
| longfei_zhang | vikasc, i mean in one openstack env , we might have server independent project/tenant, if all of them want deploy k8s cluster and want use kuryr project | 08:21 |
| vikasc | longfei_zhang, now i think i got your point about one kuryr instance per k8s cluster. | 08:21 |
| longfei_zhang | yes, sorry for the confusion | 08:22 |
| *** salv-orlando has quit IRC | 08:23 | |
| vikasc | longfei_zhang, no problem, in such scenario yes i think while deleting neutron ports, just device_owner might not be sufficient because that will delete other kuryr's ports as well | 08:23 |
| vikasc | longfei_zhang, tbh, never tried and tested thic scenario | 08:23 |
