<p>Follow-up: I guess I can leave off the <span style="font-family: courier new,courier,monospace;">--hostname</span> part of it and it doesn't change the hostname.</p>

<p>Rob, here's what I see in that log:</p>
<p><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG Using servers from command line, disabling DNS discovery</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG will use provided server: ipa.services.foo</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG will use discovered realm: IPA.SERVICES.FOO</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG will use discovered basedn: dc=ipa,dc=services,dc=foo</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z INFO Client hostname: 10.100.15.209</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG Hostname source: Provided as option</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z INFO Realm: IPA.SERVICES.FOO</span><br /><span style="font-family: courier new,courier,monospace;">...</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG Starting external process</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG args=/bin/hostname 10.100.15.209</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG Process finished, return code=0</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG stdout=</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG stderr=</span><br /><span style="font-family: courier new,courier,monospace;">2017-04-19T21:18:23Z DEBUG Backing up system configuration file '/etc/hostname'</span></p>
<p>So whatever that external process is, I guess that's what's resetting the hostname.</p>
<p>For reference, here's the line that runs (on cloud-init) to set up FreeIPA:</p>
<p><span style="font-family: courier new,courier,monospace;"> /usr/sbin/ipa-client-install \</span><br /><span style="font-family: courier new,courier,monospace;"> --domain=ipa.services.FOO \</span><br /><span style="font-family: courier new,courier,monospace;"> --server=ipa.services.FOO \</span><br /><span style="font-family: courier new,courier,monospace;"> -U \</span><br /><span style="font-family: courier new,courier,monospace;"> --permit \</span><br /><span style="font-family: courier new,courier,monospace;"> --ssh-trust-dns \</span><br /><span style="font-family: courier new,courier,monospace;"> --principal=enrollment \</span><br /><span style="font-family: courier new,courier,monospace;"> --password="PASS" \</span><br /><span style="font-family: courier new,courier,monospace;"> --hostname="{{ ansible_eth0.ipv4.address }}"</span></p>

<br /> There is something very wrong. ipa-client should be setting a FQDN, not<br /> an IP address. /var/log/ipaclient-install.log may hold some clues.<br /><br /> rob<br /><br />

So for<br /> example, 10.100.* would be put into the 'developers' hostgroup. I<br /> can't figure out the proper format of the inclusive regex. I've tried:<br /><br /> I believe that your regex needs to match the host name, not the IP<br /> address. Unless your host name is 10.100.<something> I don't think<br /> that will match. The regex for "anything" is ".*". I think that the<br /> pcre syntax is what is used.<br /> Regards,<br /> <br /> j<br /> </blockquote>
