| trinaths | janki: ping | 07:23 |
| janki | trinaths, hey | 07:24 |
| trinaths | janki: I need your comments on https://review.openstack.org/#/c/397233/2/specs/ocata/containerised-vnfs.rst and TOSCA support | 07:34 |
| trinaths | janki: I think you might be validating at that end . | 07:35 |
| janki | trinaths, If I remember correctly, we did discuss this. I am trying to figure out way to convert tosca to dockerfile | 07:36 |
| janki | do you have thoughts on that? | 07:36 |
| *** egonzalez has joined #tacker | 07:42 | |
| trinaths | janki: what are the bottlenecks you are facing at this TOSCA to DOCKER-FILE conversion end ? | 07:56 |
| trinaths | janki: Do we need to work re-design TOSCA or DOCKER file ? | 07:56 |
| phuoc_ | trinaths: Hi | 08:15 |
| phuoc_ | I am focusing containerized VNF with Janki | 08:15 |
| phuoc_ | so, in this week, I will make a spec about it | 08:15 |
| phuoc_ | I think Tosca lacks of support for container now | 08:18 |
| trinaths | phuoc_: Can you outline what support TOSCA lacks currently ? | 08:32 |
| janki | trinaths, phuoc_ TOSCA has support for docker. we need to work on translator to convert tosca to dockerfile | 08:37 |
| phuoc_ | but if we choose K8s as VIM, i think we need to find out the way to translate tosca to kubernetes template | 08:38 |
| *** trinaths has quit IRC | 08:38 | |
| phuoc_ | it is better than dockerfile | 08:39 |
| *** trinaths has joined #tacker | 08:41 | |
| trinaths | phuoc_: when we choose k8s, we are with other VIM other than openstack' | 08:46 |
| trinaths | janki: what is your idea to convert TOSCA to DOCKER file ? does this work make collaborate with other openstack projects ? | 08:47 |
| janki | trinaths, we can think of collaboration once we have dockerfile ready | 08:48 |
| phuoc_ | maybe, but we should care about making chain between VNFs | 08:49 |
| trinaths | phuoc_: chaining is a secondary issue. primary is TOSCA based definition | 08:53 |
| trinaths | janki: what lacks from docker file ? | 08:53 |
| janki | trinaths, I am in meeting currently, will get back by EOD | 08:54 |
| trinaths | phuoc_: Have you tried mapping of TOSCA cVNF support to k8s templates? please share your findings | 08:54 |
| trinaths | janki: okay.. | 08:54 |
| trinaths | janki: awaiting your mail | 08:55 |
| phuoc_ | trinaths: IMO we should think about translating from TOSCA to Kubernetes template | 09:01 |
| phuoc_ | example deployment in Kubernetes: https://kubernetes.io/docs/tasks/run-application/run-stateless-application-deployment/ | 09:02 |
| phuoc_ | its better than Dockerfile because we can limit resource in container by using K8s template | 09:02 |
| phuoc_ | but 1 point I confuse is what kind of Kubernetes we should translate to (Deployment, Horizontal Pod Autoscaling,...) | 09:04 |
| trinaths | phuoc_: also you must think on how VNFM can auto-scale/heal when k8s is the VIM ? | 09:08 |
| trinaths | janki: http://superuser.openstack.org/articles/docker-containerized-openstack-heat-translator/ | 09:08 |
| *** diga has quit IRC | 09:08 | |
| trinaths | phuoc_: comments ? | 09:17 |
| *** yifei has quit IRC | 09:40 | |
| phuoc_ | trinaths: k8s can do it via Horizontal Pod Autoscaling | 10:33 |
| phuoc_ | but we should focus on Deployment first | 10:38 |
| phuoc_ | for auto-scale/healing, it can come later | 10:39 |
| trinaths | phuoc_: agree. but then tacker must be initially integrated with k8s. is that in place now? | 10:43 |
| phuoc_ | I think we can call python client of K8s as infra driver | 10:49 |
| phuoc_ | like Heat now | 10:50 |
| phuoc_ | and consider K8s as another type of VIM | 10:50 |
| trinaths | phuoc_: okay. | 11:04 |
| trinaths | phuoc_: will tacker support k8s authentication routines ? | 11:04 |
| phuoc_ | when we deploy K8s, there is a config file Tacker can use to authenticate to K8s | 11:08 |
| phuoc_ | I hope someone who is good at k8s can help about it | 11:10 |
| trinaths | phuoc_: that means, there will be some config changes required to store k8s auth-creds for tacker to use ? | 11:24 |
| trinaths | phuoc_: are you aware of what are issues with docker based solution | 11:26 |
| trinaths | phuoc_: to be integrated with openstack | 11:26 |
| phuoc_ | VIM config may change | 11:33 |
| phuoc_ | IMO networking between c-VNF and normal VNF is a problem we need to care | 11:33 |
| trinaths | phuoc_: w.r.t networking and service creation between cVNFs might really a challenging one. may be for time being we need to take help of openstack container projects to leverage cVNFs and realize VNFFG | 11:35 |
| trinaths | phuoc_: okay. thank you for nice discussion. | 11:50 |
| trinaths | phuoc_: lets do a PoC with this before a BP is proposed. | 11:50 |
