Clean pattern for sharing record values across multiple names

Could either be implemented in YamlProvider or potentially use make use of yaml features like this or this.

I’d probably lean towards the yaml route as it has some pretty powerful feautres, but we’d have to make sure that they work well with PyYaml and document a suggested way to do them.

If implemented in YamlProvider and not yaml it could potentially look something like:

---
_octodns:
  templates:
    www
      type: A
      values:
        - 1.2.3.4
        - 1.2.3.5
      geo:
        NA-US-CA:
          - 2.2.3.4
          - 2.2.3.5
'':
  _template: www
'www':
  _template: www

Is this going to be implemented? Issue is frozen for more than a year.

It’s still on the wish-list, but not specifically on my TODO list atm. The new dynamic record support coming in the next few weeks/months will take a big step in this direction through “pools” and “rules” being separate concepts. That doesn’t solve the general case and things will still be scoped to a record.

Happy discuss options here and look over a PR once we’ve settled on a direction. Otherwise it’s probably going to stay a wish-list item for a while longer.

Are there any further plans to implement a template logic like this?

Not sure how/why this is closed. Probably accidental.

I have a lot of thoughts on what sorts of templating I’d like to see after having spent more time using octoDNS for real. My biggest want is now is to actually be able to provide a set of values that get filled in on a record. We have a bunch of duplicated value and geo keys on records. This would especially be useful if it could lay out the structure (geo used etc.) and fill in the values (ips), but I’m not aware of anything in yaml’s functionality that would support that, PyYaml or not.

It would be great to have per zone and global (per config) templates that can be used across zones

Yeah. That’d be useful for the geo structure stuff mentioned above as well. All of our records with geo support have exactly the same locations pointed to the same regions, just with different IPs. I’d be nice to be able to manage that structure once and have all the records across our zones fill in the specific ips used there.

Not sure when this will be looked into, but it’s definitely somewhere on the nice to have list.
