| arun__ | HELP | 11:27 |
|---|---|---|
| arun__ | I am trying to setup maas | 11:27 |
| arun__ | and adding one machine node | 11:28 |
| arun__ | but unable to commision the same | 11:29 |

| JJ__ | Trying to troubleshoot a problem with my maas setup relating to the public interface | 16:57 |
| JJ__ | My private interface is managed by MAAS along with DHCP and it seems to work fine, I can run conjure-up and it tries to bootstrap a juju node | 16:58 |
| JJ__ | however it gets stuck at running machine configuration scripts | 16:59 |
| JJ__ | I can ping google.com from the maas server on the public interface, I can't ping google.com from the juju node after ssh in | 16:59 |
| roaksoax | Calvin`: not supported today unfortuantely | 17:03 |
| roaksoax | Calvin`: err sorry | 17:03 |
| roaksoax | arun__: that sound slike the machine cannot access the maas metadata. Make sure /etc/maas/rackd.conf points to itself in an IP that the machine can communicate to | 17:04 |
| roaksoax | JJ__: so either you setup NAT'ing | 17:06 |
| roaksoax | JJ__: or you tell juju to use MAAS as a proxy | 17:06 |
| JJ__ | hmmm... currently have 2 subnets in maas | 17:07 |
| JJ__ | one is private with dhcp managed by maas | 17:07 |
| JJ__ | other is public with dns and dhcp provided by switch downstream | 17:08 |
| mup | Bug #1750884 opened: [2.4, bionic] /etc/resolv.conf not configured correctly in Bionic, leads to no DNS resolution <cloud-init:New> <MAAS:Triaged> <nplan (Ubuntu):New> <systemd (Ubuntu):New> <https://launchpad.net/bugs/1750884> | 17:09 |
| roaksoax | JJ__: right, but MAAS can install things from the archive because they use the apt proxy, aka MAAS | 17:12 |
| roaksoax | JJ__: the system itself cannot reach the internet because it doens't have a global proxy configured | 17:12 |
| roaksoax | JJ__: which is why either you enable NAT'ing, or tell the services you deploy with juju to use the proxy | 17:13 |
| JJ__ | for maas dashboard under settings I have proxy set for MAAS built-in | 17:13 |
| JJ__ | so you can enable NAT'ing through MAAS? | 17:14 |
| roaksoax | JJ__: yes, that's APT proxy | 17:14 |
| roaksoax | JJ__: that's not a "system" proxy | 17:14 |
| roaksoax | JJ__: https://askubuntu.com/questions/852154/juju-2-0-proxy-for-bootstrap/852931 | 17:14 |
| JJ__ | Ok, not that familiar with conjure-up open stack kvm install. How do you tell the services deployed with juju to use the maas proxy? | 17:15 |
| roaksoax | JJ__: so you can do two things. IF you want machines to have access to the internet regardless of wether juju deployed them | 17:15 |
| roaksoax | JJ__: you need to enable NAT | 17:16 |
| roaksoax | how would you do that? If MAAS is your gateway, you need iptables rules to forward traffic | 17:16 |
| roaksoax | from your public net, to hte internal net | 17:16 |
| roaksoax | if you dont want to do that, you can tell juju to use a proxy. And that proxy would be MAAS | 17:16 |
| JJ__ | Like this? https://askubuntu.com/questions/590449/maas-network-and-nat | 17:20 |
| roaksoax | JJ__: yeah similar | 17:26 |
| roaksoax | JJ__: personally, I always use NAT | 17:26 |
| roaksoax | but i jsut run a test environment | 17:26 |

| JJ__ | roaksoax__: in reading both links about proxying and NAT, it seems they apply to a situation where the maas server is the only server with 2 nic's | 18:23 |
| JJ__ | roaksoax__: in my situation all nodes have 2 nic's with one for the private subnet managed by MAAS and the other for public network. | 18:24 |
| catbus | roaksoax: Hi, wondering if you got my question yesterday and whether I missed the reply because I was on and off the chat. | 18:38 |
| catbus | roaksoax: I think I found the answer, https://github.com/maas/maas/blob/master/src/provisioningserver/drivers/pod/virsh.py only attach one interface. Even though I have two defined for the VM node (cloud-init is configured accordingly) but only one interface is created along with the VM creation. | 19:06 |
| JJ__ | anyone know why maas wouldn't pass the gateway or allow the gateway to be passed from an external DHCP server? | 19:30 |
| roaksoax | catbus: we dont use the templates from kvm/libvirt, we use our own | 19:31 |
| JJ__ | after commissioning I have tried auto assign, DHCP & Static for the public interface and none seem to allow the gateway to be passed to the node in its cloud config file | 19:32 |
| JJ__ | maas correctly passes the gateway for the private managed interface | 19:33 |
| JJ__ | if a gateway is passed it appears that NAT works, without a gateway - no NAT | 19:37 |
| catbus | roaksoax: I don't follow. What do you mean we don't use the templates from kvm/libvirt? | 19:47 |
| roaksoax | catbus: we dont create vm's based on what you have manually defined in libvirt | 19:47 |
| roaksoax | e.g. if you have multiple networks in libvirt | 19:47 |
| roaksoax | we dont use that | 19:47 |
| catbus | roaksoax: yeah, I have to manually attach the second nic to the VM to use the second bridge I create on the kvm host. | 19:48 |
| catbus | thanks for the confirmation. | 19:49 |
| JJ__ | roaksoax__: do you know if there is an issue with maas passing gateways ending in .254 instead of .1 | 20:17 |
| roaksoax | JJ__: no known issues, shouldn't really be an issue if maas is the gateway or is not the gateway | 20:41 |
| roaksoax | JJ__: when you configure DHCP you should tell it where the gateway is | 20:41 |

| JJ__ | roaksoax__: I have the gateway configured in maas and in an external dhcp for the public internet interface, it is unmanaged and although I can get maas to assign an ip address from a range, the gateway doesn't pass through. | 21:13 |
| JJ__ | I tested the external dhcp and it does pass the gateway | 21:13 |
| JJ__ | roaksoax__: is it possible to deploy a node with 2 fabric's, one on a private subnet with dhcp managed by maas and one on a public subnet with dhcp provided externally | 21:18 |
| JJ__ | roaksoax__: according to the maas docs unless I am reading it wrong, it appears for the public subnet where dhcp is not managed by maas it doesn't pass the gateway to the node during deployment. | 21:24 |
| roaksoax | JJ__: yes it is possible | 21:46 |
| roaksoax | JJ__: you just have to set the interface to DHCP | 21:46 |
| JJ__ | roaksoax__: when I set the public interface to dhcp then maas doesn't pass the gateway in the cloud config file and I haven't found a persistent way to modify the interface on the node to add it in. | 22:01 |
