KLuka_Hi gongysh08:29
KLuka_I am checking your comment in https://review.openstack.org/#/c/241762/08:30
KLuka_"had better to do log if --debug is enabled."08:30
KLuka_If I understand correctly, you suggest to log exception?08:31
gongyshKLuka_, yes08:47
gongyshnot much. I mean if --debug is enabled, we should print more there08:48

karimb_sripriya_ i m planning to do some puppet modules to ease deployment of tacker btw11:51
sripriya_karimb_: cool11:53
sripriya_karimb_: did tacker openstack deployment work?11:53
karimb_sripriya_ i do that for telefonica ;)11:53
karimb_sripriya_ it dit work using kilo , but then there seem to be some issues and so you recommended to go latest upstream (which is fine )11:54
sripriya_karimb_: what was the issue with kilo?11:55
karimb_for me that s fine, i got a decent overview of the project goals and made some doc on how to deploy it standard way ( that is, without devstack)11:55
karimb_sripriya_ they didnt tell me in details11:55
karimb_my initial testing was fine11:56
karimb_i was surprised about this using the services tenant thing11:56
sripriya_karimb_: i see,11:58
sripriya_karimb_: yes, VNFs are currently deployed in service tenant11:58
karimb_it makes sense since the VNFS are not destined to be end user consumed i guess11:59
karimb_but the nets those VNFS connect to might live in tenant world, hence the surprise11:59
karimb_sripriya_ quick question, what s the difference between config-file and and param-file when deploying with tacker vnf-create?12:01
karimb_functionality seems to overlap...12:01
sripriya_karimb_: regarding, config-file and param-file, config-file is meant for providing configuration to a VNF through the mgmt_driver model12:03
sripriya_karimb_:param-file is a totally different feature where we parameterize the VNFD template allowing user to provide certain values during deployment time i.e create VNF12:04
karimb_ok, get it12:04
sripriya_karimb_: http://tacker-docs.readthedocs.org/en/latest/devref/vnfd_template_parameterization.html12:06
*** ilozgach has joined #tacker12:11
ilozgachHello! Are there any developers here?12:12
sripriya_karimb_: those networks are created as shared across all tenants in an openstack environment12:16
sripriya_ilozgach: hello there! welcome to tacker!12:16
ilozgachYeah :)12:17
ilozgachI have a question12:17
sripriya_ilozgach: shoot!12:18
ilozgachI manually create Ubuntu Image and loaded it into my devstack setup. Then I create VNFD using this image. But I cannot create VNF because of next error12:19
ilozgachhttp://paste.openstack.org/show/478654/12:19
ilozgachNote that this error started to appear after I installed cloud-init pkg on my image12:20
sripriya_ilozgach: looking!12:21
ilozgachPreviously I forgot to install cloud-init and I was able to start it12:21
ilozgachI added manually debug trace12:22
ilozgach2015-11-12 15:05:33.375 DEBUG tacker.vm.monitor12:22
ilozgachHere we can see that mgmt_url is Noop12:22
KLuka_ilozgach, this is reported bug https://bugs.launchpad.net/tacker/+bug/151403712:23
openstackLaunchpad bug 1514037 in tacker "vnf-create fails with TypeError: <type 'NoneType'> can't be decoded" [Critical,New]12:23
sripriya_ilozgach: the timeout for stack_create is 50 seconds12:23
*** tbharath has quit IRC12:23
sripriya_ilozgach: may be the VNF instance creation is taking more than 50 seconds to come up and hence the ERROR12:24
ilozgachSo probably this error will disappear if I somehow will decrease VNF starting time?12:24
ilozgachYeah I think so12:24
ilozgachOkay12:25
ilozgachAnother question, maybe stupid one12:25
ilozgach:)12:25
ilozgachMy aim is to create custom image with openvswitch installed12:25
sripriya_ilozgach: go ahead12:25
sripriya_KLuka_: thats a differerent one12:25
ilozgachSo I decided to go from scratch and failed12:26
sripriya_KLuka_: but throws the same error if mgmt_url is None the reason for the ERROR can be anything12:26
*** Jezogwza has joined #tacker12:26
sripriya_ilozgach: ok12:26
ilozgachNow I think that I can download Ubuntu Cloud Image12:26
ilozgachFor example Trusty12:26
ilozgachHow can I install any package on it?12:27
ilozgachI can run it using QEMU12:27
ilozgachBut it requires login/pass12:27
ilozgachAs I understand there is no any login because auth is done using keys12:28
ilozgachBut I do not have any keys too...12:28
ilozgachSo I'm able to start cloud image but not able to modify it12:28
ilozgachMaybe you can help me?12:29
KLuka_You can create and import SSH keys. And than use your private key to connect to VM.12:29
KLuka_"ssh -i key-file.pem ubuntu@<ip-address>"12:29
ilozgachHow to import key into cloud image?12:29
ilozgachHmm12:29
ilozgachSo there it "ubuntu" account on this image?!12:30
KLuka_http://docs.openstack.org/user-guide/cli_nova_configure_access_security_for_instances.html12:30
sripriya_ilozgach: you can generate a key pair in openstack itself and select it when creating the instance which will later place the key in the instance12:30
KLuka_Yes I think so12:30
sripriya_ilozgach: you dont need to use cloud_init to do that in openstack12:30
ilozgachMoreover12:31
ilozgachI want to do that without openstack12:31
ilozgachJust start it in my local QEMU12:31
sripriya_ilozgach: later as KLuka_ mentioned you can access using ssh using the downloaded private key12:31
*** Jezogwza_ has joined #tacker12:31
sripriya_ilozgach: i see, it is doable using cloud_init on QEMU, i remember doing something similar long ago12:32
ilozgachMaybe I missunderstood smth12:33
ilozgachBut after I created keypair12:33
*** Jezogwza has quit IRC12:33
*** Jezogwza_ is now known as Jezogwza12:33
ilozgachI have to load public key on the remote machive12:33
ilozgachupload*12:33
KLuka_ilozgach, yes12:34
ilozgachBut how to upload it if I do not have logopass?12:34
KLuka_openstack does that for you12:34
KLuka_You just need to select the correct keypair12:34
KLuka_when you launch instance12:35
ilozgachIs that possible to do that without openstack? :)12:35
sripriya_ilozgach: it is doable using KVM util packages to build an image with cloud-init and later boot it using the cloud-init12:36
KLuka_I don't know :) You could maybe mount the image and inserted the key directly to virtual drive12:36
sripriya_ilozgach: not straight forward though12:36
KLuka_But I have never done that :)12:36
ilozgachOk, I get it! :)12:36
ilozgachAnother question )12:37
ilozgachWhen I created custom image12:37
ilozgachThe result is huge12:37
ilozgach1.7 GB12:37
ilozgachHow ubuntu cloud images are created?12:38
ilozgachSo they are ~300 MB12:38
ilozgachIs there are any guide how to do create minimalistic images?12:38
sripriya_ilozgach: are you allocating storage disk also as part of image?12:39
ilozgachI'm not sure... I followed these instructions http://docs.openstack.org/image-guide/content/ubuntu-image.html12:41
ilozgachAnd I got 2.4 GB image!12:41
ilozgach1.7 GB in case if I use original server ISO instead of mini.iso12:42
sripriya_ilozgach: did you try creating a QCOW2 image?12:43
sripriya_sripriya_: i'm not an expert on images, but they are usually smaller and preferable in kvm hypervisors12:44
sripriya_ilozgach: usuallu cloud images are QCOW2 images12:45
ilozgachYes, both images have qcow2 format12:46
sripriya_ilozgach: hmm did you specify the container size when you created the QCOW2 image?12:52
ilozgachDo you mean that?12:53
ilozgachqemu-img create -f qcow2 /tmp/trusty.qcow2 10G12:53
sripriya_ilozgach: whats the 10G for?12:57
ilozgachJust as default value12:57
ilozgachMaximal disk size I guess12:58
sripriya_ilozgach: suspecting if thats the problem,12:59
ilozgachProbably...13:00
ilozgachI have to play with that13:00
ilozgachWell, thanks everyone! You are super! :)13:01
sripriya_ilozgach: happy to help if its useful in anyway13:01

*** bobh has joined #tacker13:13
*** Jezogwza has quit IRC13:15
*** bobh has quit IRC13:20
gongysh_sripriya_, it seem he is not on the channel13:21
gongysh_sripriya_, what is the format of yaml for our vnfd creation?13:22
gongysh_tosca?13:23
gongysh_sripriya_, can u give me the format URL?13:23
KLuka_Here you have many sample files: https://github.com/openstack/tacker/tree/master/devstack/samples13:33
gongysh_yes, that is sample file, but what is behind this file's format?13:36
KLuka_From Tacker wiki: "Tacker uses TOSCA for VNF meda-data definition. Within TOSCA Tacker used NFV profile schema, ..."13:41
KLuka_https://wiki.openstack.org/wiki/Tacker13:41
KLuka_But as far as I understand this is not complete yet...13:42
*** lhcheng has joined #tacker13:45
*** lhcheng has quit IRC13:49
sripriya_gongysh_: we are currently following the simple profile for creating VNFD templates13:51
sripriya_gongysh_: NFV profile is an action item for Mitaka which bobh is working on with tosca-parser guys13:51
sripriya_gongysh_: sridhar_ram is attenting the OPNFV summit and may be that is why he is offline13:55
gongysh_sripriya_, does the tacker plan into openstack-governance? https://review.openstack.org/#/q/status:open+project:openstack/governance,n,z13:55
sripriya_gongysh_: yes, that is our goal for our Mitaka, we have almost everything in place to get us to governance project13:56
gongysh_that's great.13:56
sripriya_gongysh_: yes, some cleanup activities needs to be finished before getting to that step13:58
gongysh_sripriya_, can u clean up the previous device and device_template API?13:59
sripriya_gongysh_: we have awesome developers in tacker community, we want to encourage more developers to join hands as we have plenty in pipeline to make tacker the default NFV orchestrator for telcos.13:59
sripriya_gongysh_: we are going to take that up sometime soon during this cycle to stop supporting device and device templates14:00
sripriya_gongysh_: we retained that for backward compatibility as there is one vendor still using those APIs14:00
sripriya_gongysh_: once we get them on board for MANO apis we can remove the old APIs14:01
gongysh_sripriya_, thanks14:02
