TrevorV|HomeI manually performed the SFTP file transfer via paramiko for the SSH driver, and the file ends up with 664 permissions.16:57
TrevorV|Homeis 600 what we want on the amphora, or 644, or what?16:58
xgermanwe want 600 for cetrificate pem files16:58
xgermansince they contain private keys16:59
xgermanhaproxy file doesn't matter16:59
TrevorV|HomeAlright, but for consistency I'll do 600 for all.17:09
xgermansounds good ;-)17:12
TrevorV|Homexgerman, ptoohill has jinja set up to accept custom log value locations type of thing.17:16
TrevorV|Homelog file***17:16
xgermanperfext17:16
ptoohillwell, its not there yet17:17
TrevorV|HomeHe's suggesting a separate review to make it actually set up that way though, since its outside the scope of the ssh_driver itself.17:17
ptoohillbut it will be17:17
TrevorV|Home(should let him speak for himself :P  )17:17
ptoohill:)17:17
ptoohillill make update to take all those in as params and just default to whats in the template if None is provided17:17
ptoohillthe template is a config file, in fact the template can be a custom template placed anywhere17:18
xgermanyou know our views differ here... but sounds ok17:18
ptoohillif the operator wants to do something slightly different with the templates they should be able to17:19
ptoohillother wise this could have been all stringed up with no need for a template17:19
ptoohillkinda like v1 was17:19
xgermanwell, sno template is just a mess... but this will work for me...17:20
ptoohillsno?17:21
ptoohiller no*?17:21
ptoohill:P17:21
ptoohillfair enough17:21
ptoohillitll be configurable17:21

rm_workit should work, I think -- blogan>20:34
rm_work?20:34
bloganmspreitz: i have not actually tested that out, but I would think it would20:39
*** kobis has quit IRC20:40
rm_workso really that's a question for the deployment backend, I think -- for example, if it is the HAProxy backend, then it is whether or not HAProxy supports this20:42
rm_workor if it's A10 as the backend, does A10's LB support this20:42
bloganhaproxy does, but since the vip port is created in neutron_lbaas, that would be a factor as well20:42
rm_worksince Neutron-LBaaS really just handles the deployment/configuration of the LB solution20:43
bloganbut yeah after that, depends on what the driver is capable of20:43
blogani dont see how any of the software load balancers wouldn't support that though20:45
mspreitzAnd none of this requires both IPv4 and IPv6 subnets on the same Neutron network, right?  The LB's front side can be on a different network than the backends, with no Neutron router between them, right?20:58
mspreitzblogan: rm_work: ^^20:58
rm_workdepends on the plugin again, i assume20:59
rm_workbut, probably20:59
mspreitzrm_work: let's say the HAProxy plugin for LBaaS, to make it concrete20:59
rm_workfor HAProxy that would work, since we'd just plug the member networks as well as the frontend network20:59
mspreitzthanks21:00
dougwigyou could put both ends on non-neutron networks with some drivers, if you were insane.  :)21:03
*** sbfox has joined #openstack-lbaas21:06
*** ajmiller has quit IRC21:07
dougwigdo any of our tests actually exercise the v6 code path?21:07
mspreitzdougwig: good question!21:09
bloganmspreitz: i actually do not believe the haproxy one right now supports frontend and backend on separate networks, so ipv6 frontend and ipv4 backend would not work (unless there's some way to get ipv4 and ipv6 addresses on the same subnet)21:10
blogandougwig: not that i know of21:10
dougwigwhich of us should file a bug to get that addressed?21:10
bloganreason being is we wanted to get parity with v1, and v1 did nto support this either21:10
dougwigthe tests, i mean.21:10
*** sbfox has quit IRC21:10
blogandougwig; he who smelt it dealt it21:11
bloganneed to put that multi-network load balancing implementation in the vancouver talks21:12
bloganbc the question will come up as to who is responsible for setting up the connectivity with the members, the plugin, driver, or user21:12
dougwigerr, huh?21:13
bloganso members have the subnet_id on them now right?21:14
dougwigisn't the fix for that to switch to octavia as the ref?   or several of the vendors can handle that scenario just fine as well.21:14
bloganokay if octavia becomes the ref then that would fix it yes21:14
bloganbut octavia will be creating the amphora ports on the member networks21:14
bloganhow does your driver connect up the frontend and backend if they're on two different networks?21:15
bloganwait thats why you needed that query in yoru driver right?21:15
rm_youblogan: wait, why does haproxy care?21:15
dougwigit either leaves it as an exercise for the grader, or plumbs itself directly into the vxlan/vlan and goes direct.21:15
rm_youif the routes exist at the system level, why does it matter?21:15
bloganthe haproxy driver in neutron-lbaas is running in a network namespace21:16
dougwigonly matters if you want to keep the traffic off your neutron node.21:16
rm_youoh21:16
rm_youright, haproxy-namespace21:16
rm_youi was thinking haproxy octavia21:16
bloganso it either needs a interface on the member networks, or its gateway does21:16
*** ajmiller has joined #openstack-lbaas21:17
bloganor its gateway's gateway, but you get the point21:17
dougwigunless you want to telepathy into the network, it does need a path to the other device, yes.21:17
*** apuimedo has joined #openstack-lbaas21:17
blogandougwig: what do you mean by grader?21:17
dougwigwe have a mode where we set ourselves up as a VTEP endpoint with OVS, and are just linked directly into the tenant mesh.21:18
dougwigblogan: that's where we just trust the implicit ip routing of the network.21:18
dougwigthose last two statements are separate, not related.21:18
bloganwell either way, to answer mspreitz question, the haproxy ns driver currently does not support it21:20
bloganoctavia should though21:20
rm_youblogan: the real answer is "it's not up to neutron-lbaas really"21:21
mspreitzblogan: thanks21:21
bloganrm_you: it is if the ref impl doesn't support it21:22
*** sbalukoff has quit IRC21:22
bloganrm_you: i mean its neutron-lbaas's problem21:22
rm_youeh21:22
rm_youi think of that as a plugin still21:22
rm_youjust happens to be the default one21:22
bloganand the one we maintain21:23
bloganespecially with dougwig's shim driver revolution21:23
rm_youbut that hopefully zero deployments use21:23
dougwigwell, it's our problem in that our ref impl is kinda lame.21:24
dougwigthe fix for that is to speed octavia into place, IMO.21:24
bloganits a problem we're working on to fix though!21:24
dougwigyes, not arguing that21:24
bloganthe network driver i've been working has been coming along well, after i thought it was done but then realized i missed a ton of shit with security groups21:25

dougwigmadhu_ak: ok, i will.21:55
madhu_akthanks!21:55
mspreitzblogan: rm_you: Let me try the 4-4 version of the question.  Can I use LBaaS with HAProxy plugin where the LB listens on one network and the backends are on a different network?22:13
rm_youapparently not with the HAProxy namespace plugin22:15
*** mspreitz has quit IRC22:17
dougwigunless we broke it, that driver used to let you put in any ip address, not just a nova vm reference.  so as long as it's routable IPs, you could add the backend on a different network that way.22:17
