| hyunsikyang__ | Now, in my test | 02:31 |
|---|---|---|
| hyunsikyang__ | I notify the node status to kubernetes. | 02:32 |
| hyunsikyang__ | But the problem is action after fault. | 02:32 |

| tojuvone | I also noticed that current: MIGRATE, LIVE_MIGRATE or OWN_ACTION are not enough. I am looking to add EVICT; and that is what I am currently implementing. So, Fenix notifies and get *_ACK as normal with instance_action: EVICT. Then it evicates pods from node as VNF is ready for that and as it has defined ReplicaSet for pods; pods will be have new instance in nodes that are not cordoned. So things are quite similar to OpenStack scenario otherwise, | 05:39 |
| tojuvone | but the source pod is just not migrated as it is, but a new one is made. I think this is again something to start with and how things are in K8S. | 05:39 |

| hyunsikyang__ | Yes. After Eviction grace time, it will start eviction. But, I think k8s evict pod to random node. isn't it? | 08:28 |
| hyunsikyang__ | And I have a question for tacker integration. | 08:28 |
| *** tojuvone has quit IRC | 08:28 | |
| hyunsikyang__ | We tested it locally. So Now, when tacker create vnf with vnfd, tacker register vnf to alarm list | 08:29 |
| *** tojuvone has joined #openstack-fenix | 08:29 | |
| hyunsikyang__ | and then, When fenix call it, we return the vnf info. | 08:29 |
| hyunsikyang__ | My question is that do we consider function between fenix plugin and tacker? | 08:31 |
| hyunsikyang__ | For example, when fenix client send RESTAPI to fenix plugin, fenix plugin can return mock message. but do we make a connection between plugin and tacker? | 08:32 |
| tojuvone | evict do not have target host as normally not the migration in OpenStack. All not maintained hosts are nova-compute disabled and in K8S cordoned, so VMs and PODs lands to wanted hosts/nodes. So nothing changed in there. | 08:37 |
| tojuvone | I do not understand your question. Currently noting has changed in the way information is traveling between Fenix and VNFM (Tacker). | 08:42 |
| hyunsikyang__ | About fenix tacker intgeration, | 09:01 |
| hyunsikyang__ | https://review.opendev.org/#/c/681157/ | 09:02 |
| hyunsikyang__ | I don't know exactly the scope of this implementation. | 09:02 |
| hyunsikyang__ | For demo, we can make a interaction between tacker and fenix. | 09:02 |
| hyunsikyang__ | but for this one, Do we make a code until registration? | 09:03 |
| hyunsikyang__ | I am little bit confused about it. | 09:03 |
| hyunsikyang__ | BTW, Do you have any blueprint for k8s-fenix integration? | 09:05 |

| tojuvone | Sorry, had doctor appointment and lunch... I am just trialing the K8S, so no BP/spec. Learning as I go. When get it working I could share it/ put to review, so can use that and comment/discuss the wy forward better. | 10:31 |

| tojuvone | By fast the Tacker BP seems to implement receiving of the AODH alarm, but nothing to process it and to make any action / reply to Fenix. | 10:43 |
| tojuvone | if looking gerrit topic is "Implementation Fenix plugin in Tacker" and then confusing second line to that refers to "VNF rolling upgrade". I guess the "plugin" should do about what it now does. Have plugi with ability to receive Fenix alarm. Then what is missing is something to process the alarm (make action and reply). Then if any VNF upgrade is to be done that is also missing. Tacker should implement a policy that if Fenix interaction exposes | 10:57 |
| tojuvone | all VNF VMs, then a rolling upgrade could be done for the VMs at the same time Fenix is maintaining/upgrading all VIM related hosts. VNF upgrade is no triggered by Fenix directly, but as I just described. It should be a special case of Fenix interaction and controlled by policy in Tacker. Fenix can sure give a hint in metadata, if Tacker policy would trigger VNF upgrade only if metadata tells that OpenStack version is upgraded or like hardware is | 10:57 |
| tojuvone | replaced. Cloud admin triggering Fenix maintenance should then agree the key/value to be caught. | 10:57 |
