/etc/hosts is not populated anymore

[Ionuț Bîru]

I have a simple setup all in one installation with the following configuration.

As operating system is Ubuntu 14.04.

I noticed that after setup-hosts /etc/hosts wasn't populated.
I usually use ssh hostname to connect to the containers.

I'm using the branch origin/stable/newton with latest commit being 04605cae23bd84b19efed1fd08358bfce2bb0ddc

FYI if you have an AIO, there is no need for keepalived. :)

Could you dump your /etc/hosts too?

root@ubuntu:~/openstack-ansible/playbooks# cat /etc/hosts
127.0.0.1 localhost

Here are the paste from ioni:

inventory https://paste.xinu.at/SUo/
openstack-ansible openstack-hosts-setup https://paste.xinu.at/ofvde8/

[Jean-Philippe Evrard (jean-philippe-evrard)]

It looks like:

- include: openstack_update_hosts_file.yml
  static: no
  when: openstack_host_manage_hosts_file | bool

from the openstack_host role was skipped.

The openstack_host_manage_host_file should be True (default of the role, and the group_vars/hosts would not override it to false).

It seems like it's an issue with the static: no

[Jean-Philippe Evrard (jean-philippe-evrard)]

Could someone try to reproduce this issue?

[Jesse Pretorius (jesse-pretorius)]

I've reproduced this, and figured out where the problem is. Patch incoming.

    Fix value for openstack_host_manage_hosts_file

    The current resulting value for the group var calculation of
    openstack_host_manage_hosts_file is \"True\"\n instead of
    True.

    This results in the conditional failing in the openstack_hosts
    role because the boolean evaluation of this value results in
    False.

    This patch removes the use of continuation so that the
    resulting value is boolean instead of a string.
