xuhaiweiHi, I used the diskimage-create.sh to create an amphora image, and I succeeded. But when I started a loadbalancer, the vm is actually not working, I accessed to the vm from vnc console, and saw the VM OS is not running at all. It shows "Not kernel loaded"06:59
sapd_johnsom: Hi. I watched your present at Vancouver. So Has octavia supported flavor on master branch yet?07:00
xuhaiweiAny idea about this issue?07:00
sapd_xuhaiwei: Have you rebuilt your image yet?07:00
xuhaiweiI built it several times, and it is still the same situation.07:01
xuhaiweiBy the way I used Ocata version script07:01
sapd_oops. What distribution did you use?07:01
xuhaiweiUbuntu, I want to create centos, but failed07:02
xuhaiweiwhen creating centos image, it shows an error, "can't uninstall virtualenv"07:03
*** ispp has joined #openstack-lbaas07:03
xuhaiweiI wonder if I can download a stable image somewhere? @spad_07:03
crazikxuhaiwei: check your build log07:04
crazikprobably you're missing some dependencies07:04
xuhaiweicrazik: build log means the diskimage-builder console log?07:05
crazikyeap07:05
crazikredirect to file, check for errors07:06
sapd_xuhaiwei: Try change build environment.07:08
xuhaiweiI have tried from three different environment, two ubuntu envs and one centos, every environment succeeded without any error . sapd_07:10
crazikm.07:10
crazikI've build several times in last week07:10
crazikon ubuntu xenial box07:10
xuhaiweicrazik: Are you using the latest version?07:12
xuhaiweiI am using ocata version07:12
crazikhm, version from master07:12
craziklet me check07:13
xuhaiweicrazik, sapd_: I can see this information from the console log "Installing GRUB2... Installing for i386-pc platform. Installation finished. No error reported. Generating grub configuration file ... Found linux image: /boot/vmlinuz-4.4.0-127-generic Found initrd image: /boot/initrd.img-4.4.0-127-generic done"07:13
xuhaiweiSo the kernel and diskimage should be fine07:14
crazikxuhaiwei: yeap, it was master branch07:14
xuhaiweiok, I will try master branch07:15

mrodriguezHi all, I asked some related questions yesterday, I still have some troubles but I would like to see if I'm understanding this right.16:09
mrodriguezI have a setup with Octavia 1.0.1 on Pike, requests use neutron-api and then pass through the neutron-lbaas driver to Octavia, requests can also go directly to Octavia using python-octaviaclient since there is an endpoint.16:09
*** dmellado has quit IRC16:09
mrodriguezWhen I create a LB passing through the neutron API, the LB gets created however if I list it with neutron-client it shows as ERROR status, on the other hand, if I list it using the octavia-client it shows ACTIVE.16:09
mrodriguezAlso if I looked at the Octavia database and the Neutron database, I got the same results, so I guess the neutron-lbaas driver is not syncing correctly with Octavia.16:09
mrodriguezI could probably use only the octavia-client and the Octavia API and get the problem solved, however we use heat to deploy our LBs and the heat resources OS::Neutron::LBaaS::* make requests pass through the neutron API and not the octavia API.16:10
mrodriguezThis makes heat to see the resource as failed since the LB is marked as ERROR via the neutron API.16:10
mrodriguezI tried to switch that to OS::Octavia::* unfortunately that is only available on Queens, I read yesterday in the channel that I can upgrade octavia to Queens, but I guess I would need to upgrade heat too to make it work.16:10
mrodriguezI haven't seen much issues related to what I'm seeing, and per the openstack doc it seems that using neutron-lbaas driver to pass request to Octavia is a common setup before queens.16:10
mrodriguezSo I wonder if you have heard about similar issues when using neutron-lbaas/Octavia.16:10

*** leitan has quit IRC16:26
johnsommrodriguez My understanding is heat has updated and supports the native Octavia API, but maybe not in their Pike release.16:26
*** gigo has joined #openstack-lbaas16:26
johnsommrodriguez yes, there are a number of issues in neutron-lbaas, thus why it is now deprecated and we are moving to Octavia.16:27
mrodriguezjohnsom: Yes, I think that is the case, at least per my test, I got messages from heat not knowing Octavia resources16:28
johnsomThe issue you are seeing may be related to configuration on Octavia which sends status events back to Neutron.  However, you will likely still see issues.16:28
johnsomThere are a  couple of options:16:30
johnsom1. Attempt to enable the event streamers (there are two) in Octavia that send events back to neutron DB.16:30
johnsom2. Use the neutron-lbaas proxy plugin that sends requests to the neutron API directly to Octavia.16:32
*** pcaruana has quit IRC16:32
mrodriguezjohnsom: and I agree, it seems a good option to use Octavia only, instead of passing through the neutron-lbaas,16:33
johnsom3. Use L7 rules at your neutron API load balancer to redirect LBaaS requests to the neutron API to the Octavia API16:33
johnsommrodiguez Yes, we found that it would be a complete rewrite to solve the issues in neutron-lbaas, which we already had in Octavia16:33
mrodriguezabout option 1, I would like to try setting sync_provisioning_status and event_streamer_driver in the health-manager service to see if that makes a difference,16:34
mrodriguezand I didn't know about options 2 and 3, so I might give it a try if option 1 doesn't help16:35
johnsomIt will help with the issue you are seeing. It does put load on your controller instances.16:35
johnsomYou will still see issues if you have a high rate of change via the neutron-lbaas API16:36
mrodriguezI see, I understand due to the limitations, so that's good to know16:37
*** sapd has joined #openstack-lbaas16:38
mrodriguezjohnsom: appreciate your help again! I'll do some tests and get back with my results16:40
johnsommrodriguez Take a look at these: https://review.openstack.org/561049 and https://review.openstack.org/53935016:41
johnsomSure, no problem, good luck16:41

rm_worksapd: so castellan is ... basically, it's only useful if your org is using Vault, and has another way to get secrets into Vault already18:02
*** amuller has quit IRC18:03
sapdrm_work: because I think maintain dogtag as a backend for barbican is quite hard.18:04
sapdI want to use vault.18:04
rm_workin that case, it is possible to use it, by configuring octavia to use the castellan driver, and then configuring castellan in our config18:04
rm_workthough... i don't have a great resource / example for that18:04
rm_workah... I don't think that's necessarily that hard... have you talked to alee in the barbican channel?18:05
rm_work`alee` = Ade Lee, he's at RedHat and does the Dogtag work in Barbican18:05
sapdrm_work: No, I have not. I'm looking for an other backend. because Dogtag has many components and the documents is not good.18:07
rm_workhmmm18:07
rm_workwell, you can also put Vault behind Barbican18:07
rm_workif you run the newest stuff18:07
rm_workhttp://logs.openstack.org/05/568905/11/experimental/barbican-vault-devstack-functional/114ebde/logs/etc/barbican/barbican.conf.txt.gz18:07
rm_workTHAT i have an example of ^^18:07
rm_workbecause I just helped with getting it working18:08
sapdrm_work: :D18:08
sapdI will try castellan and barbican.18:08
sapdI mean barbican with Vault backend.18:09
sapdbecause I deployed dogtag with 3 nodes in lab environment. And It's quite hard to manage.18:09
rm_workhmmm18:10
rm_workagain, I would poke alee about that, he might have resources to help you18:10
rm_workI know dogtag is well supported in Barbican18:10
sapdrm_work: Castellan-UI is frontend for barbican, Isn't it?18:12
sapdhttps://github.com/openstack/castellan-ui18:12
*** salmankhan has quit IRC18:14
rm_workessentially yes, which is confusing because it really wouldn't work for most backends I think18:16
rm_workor maybe it would? but like, not securely18:16
rm_workBarbican is the API that actually handles keystone auth and multitenancy18:16
rm_workif you do castellan straight to Vault, for example ... there's nothing for handling that >_>18:16

sapd:D18:23
rm_workI think you need to configure the horizon panel to use the right thing18:23
rm_workit goes to Barbican via the castellan driver, so it needs to be configured to use Barbican first18:24
rm_workagain, I would recommend you ask in the Barbican channel18:24
