muhahaOh, seems that Victoria is supported in 11.0.0.0+ and its not yet released14:18

muhahavagrant is populating /etc/hosts and rabbit install fails to it, nor sure why, maybe because of this https://bugs.launchpad.net/kolla-ansible/+bug/1862739,  i am using ussuri and ubuntu 18.04, but still hitting this problem, should i remove this host manually ?15:49
openstackLaunchpad bug 1862739 in kolla-ansible ussuri "Ubuntu /etc/hosts fix bug" [High,Fix released] - Assigned to Radosław Piliszek (yoctozepto)15:49
muhahabtw, i have mapped hostname to 127.0.2.1, not to 127.0.1.1, so maybe regex fails ?15:52
*** kevko_ has joined #openstack-kolla16:01
yoctozeptomuhaha: yes, it looks for 127.0.1.1 only16:02
*** stingrayza has joined #openstack-kolla16:12
muhahayoctozepto  sure why i have 127.0.2.1 in my /etc/hosts tho16:13
muhaha*not16:13

muhahaseems its vagrant specific https://github.com/hashicorp/vagrant/blob/master/lib/vagrant/util/guest_hosts.rb#L1616:18
r3ap3rmuhaha: in reference to your Victoria comment earlier, Victoria is currently in RC1 phase. If you install within a virtual environment, use `pip install kolla-ansible==11.0.0rc1` to install Victoria.16:20
muhahar3ap3r thanks, i will wait for final, i am just trying openstack right now16:23
r3ap3rmuhaha: np. :-)16:24
muhahais cephadm or ceph-ansible recommended for victoria ? i know i can use lvm for all-in-one deployment, but i would like to isntall full variant in all-in-one16:24
muhahajust to understand..16:25
muhahabtw, i commented https://bugs.launchpad.net/kolla-ansible/+bug/1862739/comments/18, not sure if it helps..16:26

r3ap3rI am assuming the deployment tool really doesn't matter. What really matters, for Kolla-Ansible at least, is that your pools, keyrings, ceph.conf, etc... is all configured correctly. I am personally struggling with an external ceph setup myself but it is definitely due to me being new to Ceph and it's interaction with Opentack. I used cephadm to deploy my Ceph environment.16:27
r3ap3rhttps://docs.openstack.org/kolla-ansible/victoria/reference/storage/external-ceph-guide.html16:32
r3ap3rDon't forget to swap `victoria` for your version of Openstack. ^16:33
muhahaThanks !16:37
muhahaI am totally new to openstack, and I am wondering how openstack shoud be implemented to be able to allocate public ips ?  Via VLANs and SDN ? Like Cumulus ?16:40
r3ap3rmuhaha: I am by no means an Openstack expert but I can tell you what I have learned so far. Allocating public IP addresses are done by the `enable_neutron_provider_networks` option in the globals.yml file. In Koll-Ansible, the supported option for SDN is Neutron however, there are also Tungsten Fabric(previously OpenContrail from Juniper), OpenDaylight and you can even integrate Neutron with VMware NSXv if you16:56
r3ap3rare so inclined. Tungsten Fabric and OpenDaylight have tutorials out there but they are dated for the time being. VMware NSXv is supported in Kolla-Ansible if you are more familiar with that and have a license for it. I'm more of an opensource guy myself.16:56
muhahar3ap3r what are You using? There is also Danos, VyOS, but I am not sure how much are these "integrable"16:59
*** born2bake has quit IRC17:02
r3ap3rmuhaha: personally I use Neutron for my public IPs and use VyOS internally for networks. At work, we use Openstack to build training environments so our internal networking is more important public networking and VyOS is used in abundance. I don't have access to any of the Heat Templates to share but they can get quite complex, some being over 5000 lines of yml long.17:06
r3ap3rLooking at switching to Danos though.17:07
*** e0ne has joined #openstack-kolla17:07
muhahaYou have directly connected cable from internet to openstack server and you can assign those to openstack services ?17:10
r3ap3rNah, none of our Openstack services are connected directly to the internet, we use VLANs to separate everything out. You're internal api's should never be directly accessible from the internet and we even have ACL's in place to prevent internal networks from talking to eachother. This also allows us to configure specific mtu sizes for specific VLANs. For example, storage backend MTU size is set to 9000 while the17:18
r3ap3rHorizon dashboard for logging into Openstack is set at 1500 mtu. It can get quite complex or it can be simpler depending on what level of granularity you desire or need.17:18
muhahar3ap3r  am talking more about public IPs for VMs in Openstack itself, that depends on integration with WAN stack.17:39
muhahaSame as Firewall17:40
muhahaSeems that Neuron is integrated via ML2 plugins with routers/switches then17:45
r3ap3rmuhaha: there are a few different ways you can do that. Depending on your firewall that sits in front of Openstack, you could setup HAproxy there and map them appropriately. Provider Networks have to be enable for that to work either way. Your Provider Networks will give you the ability to assign "floating IP" to an Instance. This floating IP can be a public IP if you so wish.17:46
r3ap3rmuhaha: precisely ^^17:46
r3ap3rNeutron is extremely flexible.17:47
muhahaI am just asking because I dont really know how this is working... And I am only looking for opensource projects too. Seems that Cumulus has ML2 plugin17:48
r3ap3rI don't have experience with Cumulus yet.17:50
muhahaI did not find any info about VyOS, Danos plugins17:50
muhahaAnd I believe there is not another opensource networking os..17:51
muhahaTungsten Fabric is more like overlay network17:51
muhahaAnd I am not familiar with OpenDaylight17:51
r3ap3rYeah, I think I was going in a different direction than what you were asking now that you say that. My apologies. lol17:52
r3ap3rI think what you are looking for is Neutron + OVS or Neutron + OVN. OVN is becoming the new networking standard for Openstack but OVS is still supported and from my understanding widely used.17:57
r3ap3rThat should get you up and running just as long as you enable Provider Networks, then you can assign L2 addresses to your instances.17:57
