It might be tied up with https://bugs.launchpad.net/bugs/1557769 ,
where in 1.25.4 DNS names started appearing with some providers where
IP addresses used to be. Which breaks a number of charms, but only on
the providers with the unexpected behaviour.

Re: public-address and dns of nodes are IPs instead of hostnames

[Cheryl Jennings]

There is a bug for this on juju 2.0.  I wasn't aware that it is also a
problem for 1.25.

https://bugs.launchpad.net/juju-core/+bug/1566014

Junaid - if you can get machine-0.log, can you attach it to the above bug
for analysis?

Thanks!

Re: public-address and dns of nodes are IPs instead of hostnames

[José Antonio Rey]

This was introduced a while ago, not sure if on 1.25.5, but it also 
changed the behavior on AWS, where you used to get 
ec2-ip-address-here.country.availabilityzone.amazonaws.com, and now you 
get the public IP address. Someone else, maybe from the core team, may 
be able to give you a little bit more background.

If I connect one network to the node, it shows the hostname as
public-address but if i connect a second network, it gets the IP from
second network as public address (and dns). All of my nodes are
connected to two networks except the juju bootstrap node. So from juju
status command, DNS and public address of all nodes are IPs except the
bootstrap node which has the hostname. This is a very random behavior.
is the feature introduced in 1.25.5? and also can you please share why
this feature is introduced?

I'm using juju version 1.25.5 and MAAS version 1.9.3
If i run

it outputs the correct hostnames so I'm guessing there's
something wrong
on juju side.  Also if i ssh into a node and check the hostname, the

Here is the output of

Can you anyone please help me in debugging this issue?

public-address and dns of nodes are IPs instead of hostnames

[Junaid Ali]

Hi everyone,
I'm hitting an issue on one of my deployments. $ juju stat shows IP of a
node as its public-address and dns that instead should have the hostname.

I'm using juju version 1.25.5 and MAAS version 1.9.3
If i run
$ maas  nodes list
it outputs the correct hostnames so I'm guessing there's something wrong on
juju side.  Also if i ssh into a node and check the hostname, the node has
the correct hostname.

Here is the output of
$ juju stat --format tabular
http://paste.ubuntu.com/18145396/

Can you anyone please help me in debugging this issue?

Thanks,
- Junaid
