[Pulp-dev] Object IDs in Pulp 3

[David Davis]

I’ve been working on and discussing an issue with @asmacdo about filtering
by id [0] and it’s brought up some questions about how repos, importers,
etc should be identified in Pulp 3. I think currently we uniquely identify
object’s by their href field since names are mutable. The main questions
are: how should things like Katello store ids for objects like repos?
Moreover, what identifier would a user use to look up an object in the
CLI—would they pass the object’s href?

I imagine right now that Katello would store an object’s href since we
don’t expose object’s ids. But what if the hostname changes or Pulp
switches from http to https. Then the object's identifier would change.

Similarly, as a CLI user, what could I use to uniquely identify say a repo?
Supplying the object’s href seems a bit strange I guess since you wouldn’t
expect hyperlinks in a command line interface. Would CLI users deal with
names? Those can change though which would be bad for setting up things
like cron jobs using the CLI.

Any thoughts?
