Re: LXC container and DNS names

2015-11-02 Thread Andres Rodriguez 
Hi Mark,

I just wanted to confirm that;

For 1.8, containers will show under the devices tab.

For 1.9, however, these will be shown under the Node Details page itself
(which is targeted for next week).

Hope this helps!

It would really be most useful if there were some connection between the
container name and it's host machine name, to enable someone to see
what's going on at a glance.

In future, the containers should show up on the MAAS node page ("these
are all the containers on this machine"). But for now, just naming the
"devices" with this in mind would be helpful.

Yes, in fact registering containers in MAAS (along with their MACs,
hostname, and parent instance) is what I'm working on currently. This
will allow MAAS to release the resources allocated to containers (so
far just IP addresses - static or DHCP-provided leases) when Juju
destroys a container, its parent instance, or the whole environment
(gracefully, i.e. without --force, or with --force, bypassing the
usual shutdown Juju performs and relying on MAAS to do it instead).

This will be the default behaviour starting from 1.24.8, and also will
apply the upcoming 1.25.0 release, as well as all future releases.

In order to be able to do that, for MAAS environments, Juju will
require at least MAAS 1.8+.

Containers will be registered as devices, and will have hostnames like
"juju-machine-1-lxc-2.maas" (assuming regular instances get hostnames
like "distinct-town.maas").

See bug https://bugs.launchpad.net/juju-core/+bug/1483879 for updates
on when this feature will be available for early testing, or
alternatively wait for the 1.24.8/1.25.0 releases.

LXC container and DNS names

2015-10-28 Thread Pshem Kowalczyk 
Hi,


I'm running a stable version of juju (1.24.7-trusty-amd64) and maas
(1.8.2+bzr4041-0ubuntu1 (trusty1)). I use maas to manage DHCP and DNS on
the 'bootstrap' network.


I would like to know if it's possible to get juju to register the DNS names
for the containers it spins up. For example at this stage I get:



maascontroller:~$ juju status mysql
environment: maas
machines:
  "0":
agent-state: started
agent-version: 1.24.7
dns-name: controller.maas
instance-id:
/MAAS/api/1.0/nodes/node-f2b1adb6-7603-11e5-a073-0050569a302e/
series: trusty
containers:
  0/lxc/2:
agent-state: started
agent-version: 1.24.7
dns-name: 10.0.0.148
instance-id: juju-machine-0-lxc-2
series: trusty
hardware: arch=amd64
hardware: arch=amd64 cpu-cores=4 mem=65536M tags=4cpu

relations:
  cluster:
  - mysql
  shared-db:

  mysql/0:
workload-status:
  current: unknown
  since: 29 Oct 2015 13:24:18+13:00
agent-status:
  current: idle
  since: 29 Oct 2015 13:34:53+13:00
  version: 1.24.7
agent-state: started
agent-version: 1.24.7
machine: 0/lxc/2
public-address: 10.0.0.148
networks:
  maas-eth1:
provider-id: maas-eth1
cidr: 10.0.0.0/24

I would like juju to either create something like juju-machine-0-lxc-2.maas
(and preferably  mysql-0.maas). Is this possible?


kind regards
