sripriyahaiwei: whats up?06:17
haiweisripriya: about this spec https://review.openstack.org/#/c/352943/06:19
haiweisripriya: due to your comments, Senlin related resources can't be exposed to end user, but Senlin needs a policy type resource to realize this function, so should we add a new type policy resource just like the current existing one?06:20
sripriyahaiwei: what is the new resource type required for senlin?06:23
haiweisripriya: because senlin's policy format is different from the exsiting scaling policy, and for vnf HA, a new type HA policy may be needed also06:25
sripriyahaiwei: i think it is okay to introduce a new policy for HA06:26
sripriyahaiwei: however with scaling i would like to understand the deviations from existing scaling policy06:27
*** trinaths has joined #tacker06:27
haiweisripriya: when using senlin to manage auto-scaling, the senlin type heat resources should be created from the HOT template, so in the TOSCA template there should be a resource special for Senlin, or else, senlin resource can't be created06:31
haiweisripriya: Heat-translator can translate a 'tosca.policies.Scaling.Cluster' type policy for senlin, different from the scaling policy type in Tacker, and the content of the policy is a little different too, for example the senlin's policy is targeted to a Senlin cluster, not to a VDU06:34
haiweisripriya: Senlin invented the concept of 'cluster', all the policies are attached to the cluster, and the scale-in/scale-out actions are done to the cluster, that is the main differences of Heat auto-scaling group I think06:37
sripriyahaiwei: can't we just translate the tosca scaling policy to senlin based on the configured backend?06:39
sripriyahaiwei: like today we handle this translation on tacker side to translate scaling to heat auto scaling group06:40
sripriyasimilarly we could do for senlin as well?06:40
haiweisripriya: I am not clear where is the backend configured in Tacker, can you show it to me?06:41
sripriyahaiwei: this is not there presently, i'm suggesting if we can do it06:52
haiweisripriya: I just looked up the source codes of infra_driver/openstack, it messed all the things together, IMO06:54
sripriyahaiwei: agree on that, we need some refactoring there06:55
sripriyahaiwei: especially on create method06:56
haiweisripriya: yes, if there source code of scaling part can be filtered out, I think it's possible to swith it from heat-autoscaling-group and senlin06:57
sripriyahaiwei: yes06:57
haiweisripriya: so we need to do is to refactor the infra_driver part06:59
haiweisripriya: firstly06:59
sripriyahaiwei: yes, and handle scaling as a configurable backend07:00
haiweisripriya: agree07:01

bobhtbh:pong16:45
tbhbobh, regarding your comment on #470 in https://review.openstack.org/#/c/304667/17/specs/ocata/nsd-support.rst16:46
tbhbobh, as you already know, we are importing VNFD using VNF name(which already launched)16:46
tbhbobh, so how we can pass input parameters from nsd?16:47
bobhtbh: if the VNF has already launched, what is the purpose of the NSD?  Is it just defining network paths through existing VNFs?16:47
tbhbobh, ah got your point!16:49
tbhbobh, it must be onboarded VNFD IDs16:49
tbhbobh, I think there is no support to pass input params from parent template using substitution  mappings,and I pinged sahdev regarding the msae16:51
tbh*same16:51
dkushwahatbh, bobh VNFDs will bealready on-boarded but no VNFs created16:51
tbhdkushwaha, yes I misunderstood it16:52
bobhdkushwaha: tbh: so there  needs to be a way to pass required input parameters from the parent NSD to the VNF(s)16:52
tbhdkushwaha, it must be VNFD in the spec16:52
tbhbobh, yes16:54

dkushwahasripriya, hi17:50
dkushwahasripriya, kindly give your thoughts on nsd spec https://review.openstack.org/#/c/304667/ on comment #47017:54
sripriyadkushwaha: will respond today.17:56
dkushwahasripriya, thanks17:56
sripriyadkushwaha: what bobh is asking for input param support we can stilll do that through vnfd which then just gets imported as vnfd name in nsd17:57
sripriyaSo we do not support parameterization in nsd directly right?17:58
sripriyadkushwaha: ^17:58
dkushwahasripriya, yes17:58
tbhsripriya, but we have to those param values from nsd18:01
tbh*have to pass18:01
*** dkushwaha_ has joined #tacker18:02
*** dkushwaha has quit IRC18:04
sripriyatbh: why? The vnfd id already onboarded right, we expect the user to have passed at that point itself?18:06
tbhsripriya, I think when we launch VNF, we need to pass params?18:08
tbhsripriya, otherwise no need of params right? as we have fixed values for the VNFD18:09
sripriyatbh: ah got your point, yes we may need to pass those params during nsd18:27
sripriya*nsd creation18:27
bobhparameters are needed during ns-create just like vnf-create - there is really no difference between doing a vnf-create and an ns-create - a vnf is just a NS with one VNFD18:45
