NarutobapuI am planning for instance HA via heat service. can someone post the link has steps to be followed and required heat tempalate for Instance HA (not service HA). I am orchestrating docker container using openstck kilo.10:11
*** hoangcx has quit IRC10:19
aspiersNarutobapu: instance HA cannot be accomplished reliably with heat, because there is no fencing10:19
*** hoangcx has joined #openstack-ha10:19
Narutobaputhen what is the best way to achieve it?10:26
aspiersthe easiest way by far is to use one of the vendor solutions which supports it10:29
aspiersIn SUSE OpenStack Cloud it's just drag and drop. I guess Red Hat has something similar (at least it uses the same mechanism behind the scenes) but I don't know what their UI is like10:31
*** markvoelker has joined #openstack-ha10:31
Narutobapuwe have private cloud. i cannot use public cloud solution. is openstack doesn't come up with solution?10:34
aspiersNarutobapu: SUSE OpenStack Cloud and RHEL OpenStack platform are for private cloud10:35
aspiersthey are the only well-tested and vendor-supported solutions for private cloud which I know about10:35
*** markvoelker has quit IRC10:36
aspiersin the upstream OpenStack community we are working on another solution but it is still experimental10:36
aspiershttps://etherpad.openstack.org/p/automatic-evacuation10:36
aspiersthere's also masakari, but you would have to support that yourself10:37
aspiersAFAIK I don't think it's possible to pay NTT for support10:37
aspierssee also http://www.slideshare.net/adamspiers/compute-node-ha-current-upstream-development10:38
Narutobapui have ubuntu LST 14.04.  does SUSE and RHEL support on this plateform?10:38
aspiersand if you are coming to Austin, come to our talk https://www.openstack.org/summit/austin-2016/summit-schedule/events/732710:38
ddejaaspiers: Narutobapu said, that he is orchestrating docker Containers, I don't know if SUSE or RH support this?10:38
aspiersSUSE supports Docker as an OpenStack hypervisor10:39
aspiersI don't know about RH10:39
Narutobapuyes that's right, i am using nova-docker10:39
Narutobapuwhat about masakari? does that support ha for containers?10:40
ddejaaspiers: as far as I understand, Narutobapu don't want to have service in containers, but he is orchiestrating containers like VMs10:41
aspiersddeja: right. SUSE OpenStack Cloud supports that10:42
ddejaNarutobapu: from what I know, Masakari only supports ha for virtual machines10:42
aspiersNarutobapu: I think masakari only works with libvirt10:42
aspiersI don't think we tested compute node HA with docker hosts, but it should work10:43
ddejaaspiers: I'm not so sure10:43
ddejawe are using 'nova evacuate' commands after all10:43
ddejaand I'm not sure if it work with docker container10:43
aspierswhy not?10:43
_gryfit should10:44
_gryfit will just rebuild the container in another host10:44
aspiersright10:44
ddejaok then10:44
ddeja:)10:44
aspiersbut I don't think we tested that10:44
_gryflive migration is complitely different story10:44
Narutobapuabout compute node HA,  is there any options (in conf files) i have to configure? because right now if i make one of my container down, it doesn't come up automatically.10:53
aspiersNarutobapu: yes there is a huge amount of configuration and it's complex and difficult to get right10:55
aspiersthat's why SUSE and Red Hat put a lot of effort into automating it, so that other people don't have to10:55
aspiersand other people like ddeja from Intel helped with this too :)10:56
Narutobapuso there is no documentation or link , that i can follow?10:57
aspiersnot for doing it upstream, no10:57
aspiersalthough I think bogdando is aiming to start documenting it10:58
aspiersbut it's a moving target10:58
Narutobapuok thanks, @aspiers . :) looking forward for solution.10:59
