An excerpt from

Right after a host called “foo” is built, just before the first puppet run, the /etc/hosts file contains the following entry: foo

However, in order to match the information that is in DNS, I want the line to look like this: foo.colo.domain foo

Let’s try to keep aside the discussion of whether that is actually a sane thing to do, I’m still just experimenting. Let’s focus on what may be necessary to make puppet replace the existing line with what I want there to be. I added something like this to the manifest:

        host { foo: ensure => absent }
        host { "":
                ip => "",
                alias => [ "foo.colo.domain", "foo" ]

However, surprisingly (or maybe not), what I get is just an early failure:

Host[] is already being managed

This is because of the dual purpose of “alias” param/metaparam.

I think this may be related to #1221

  • Category set to language
  • Status changed from Unreviewed to Needs More Information
  • Assignee set to Luke Kanies

I can verify this behaviour; Luke, could you please clarify if you’d like this accepted (and thus eventually fixed, perhaps renaming the alias parameter to the host{} type.. so we can keep the alias metaparameter functional for this type, while still providing the ability to manage multiple ‘aliases’ per host{}?

#2 Updated by Luke Kanies over 7 years ago

  • Category changed from language to RAL
  • Status changed from Needs More Information to Accepted
  • Target version set to 4

Because we consider aliases to be equivalent to names, in terms of causing naming collisions, it seems that the parser should correctly match these hosts.

It’s probably a good bit of work, though.
