ltomasbohi apuimedo07:09
ltomasboI've checked how octavia l2 handles the traffic towards the loadbalancer07:10
ltomasboand a new security group is created for each lbaas07:10
ltomasboso, I think the addition needs to be done on code, rather than devstack07:11
ltomasboany thoughts?07:16

openstackgerritKien Nguyen proposed openstack/kuryr-libnetwork master: [WIP] Support specifying existing subnet uuid/name  https://review.openstack.org/49949307:54
apuimedoltomasbo: I think it is weird08:10
apuimedoxD08:10
ltomasboapuimedo, so, any other (better) solution in mind?08:12
apuimedoltomasbo: you mean that you need to create a rule in the SG of the octavia port?08:13
apuimedocause if that is the case, it is very strange indeed08:13
ltomasboI meant that, when you expose a service08:14
ltomasboa new amphora is created08:14
ltomasboand the port in the k8s-service-net has a newly created (by octavia) security group08:15
ltomasboso that happen at run time and not while deploying the environment08:15
*** openstackgerrit has quit IRC08:17
apuimedoand which rule do you need to add?08:29
ltomasboapuimedo, that is what I'm checking08:35
ltomasboI'm digging08:36
ltomasboI see the amphora VM has 3 connection, and the one in the k8s-service-subnet is the vrrp one08:36
ltomasbothen, the lbaas port (also in k8s-service-subnet) also has the same security group, the newly created08:36
ltomasbolb-XXXX08:37
ltomasboso, I'm assuming I need to add a rule to that one allowing traffic from k8s-pod-subnet08:37
*** vikasc has quit IRC08:37
ltomasboapuimedo, this is what this sg includes: http://paste.openstack.org/show/619990/08:39
apuimedoltomasbo: what I'm saying is, try to create the rule manually, see if you get it to work08:40
apuimedothen report which rule (and to which group) fixed it08:40
ltomasbook08:40
ltomasboI'll find the solution, and then we discuss how/where to add it08:40
ltomasbomy point was that most probably we need to do it in code, rather than devstack as it is being created at service exposing time08:41
apuimedodepends on where it falls08:42
ltomasboyep08:42
ltomasbomy concern is that port 80 is already included, not sure why it is not working08:42
ltomasboI'll dig a big more...08:42
*** garyloug has joined #openstack-kuryr08:49
apuimedo:-)08:50
apuimedoltomasbo: you're starting to see why I excluded L208:50
apuimedoI just couldn't figure it out in a day08:50
ltomasboyep08:51
apuimedogot mad and rage quit08:51
ltomasboyesterday I was thinking, this was soo easy08:51
ltomasbohow come apuimedo didn't included both directly08:51
ltomasbonow I see why08:51
ltomasboI added ping, ssh and port 80, and still no connectivity... tcpdump to the rescue...08:51
apuimedoltomasbo: ovs firewall or hybrid?08:52
ltomasboit is the default one, so hybrid08:53
ltomasbomaybe I should change to firewall08:53
apuimedoltomasbo: what I meant to say is08:54
apuimedoyou can try to flush the iptables08:54
apuimedoand see if it works08:54
apuimedo:P08:54
ltomasboI see ping from container to the amphora VM arrives to the amphora tap on k8s-service-subnet08:55
ltomasboso, it should not be iptables (at least not on the server, perhaps inside the VM)08:55
ltomasboapuimedo, icmp request reaches amphora VM tap device, but not the amphora-haproxy namespace inside the amphoraVM09:04
ltomasboapuimedo, wait, it does reach the namespace! http://paste.openstack.org/show/620003/09:07
apuimedoltomasbo: ain't it nice how tcpdump in the namespace is somehow delayed?09:17
ltomasboyep, I would like to have live output instead of having to stop it09:19
apuimedoxD09:23
ltomasboapuimedo, and iptables in the namespace are empty, I wonder why this is not working...09:23
apuimedoit's retarded09:23
apuimedoI wonder what causes it09:23
apuimedo(the delay)09:23
ltomasbono idea09:31

ltomasboI think I didn't explain myself enough, and he only checked what is was working (qrouter namespace to service, not pod to service)12:47
