Foreman API : hosts classes?

Support
1

Hi,

I'm wondering if there's a way to list all hosts and their associated classes, without having to query the api for each host ?
Currently, with /api/hosts, I only this kind of thing :

{"host":{"name":"myhostname","id":139,"hostgroup_id":5,"operatingsystem_id":1}}

But even if the hostgroup has classes associated with it which I can parse, this host in particular has other classes which apparently aren't listed here…
I've found the classes in "/api/hosts/myhostname/puppetclasses?format=json", but I would like to avoid having to do an api call for each host… is that possible ?

Thanks

There may be better ways, but what I would try is to use scoped search.

I didn't found any query to get host and classes joined together, so you
have to do it in more requests.
Here are some clues you could use to make your search more optimal.
I also added equivalent for hammer (CLI) as it may be easier to use in
some cases (and it has export to csv).

You can list hosts by class:
> hammer host list --search 'class=ntp'
API: GET "/api/hosts?search=class%3Dntp"

You can list classes by host:
> hammer puppet_class list --search
'host=centos.mbacovsk.com|host=foremandevel.mbacovsk.com'
API: GET
"/api/puppetclasses?search=host%3Dcentos.mbacovsk.com%7Chost%3Dforemandevel.mbacovsk.com"

You can list classes being used by any host:
> hammer puppet_class list --search 'set? host'
API: GET "/api/puppetclasses?search=set%3F+host"

You can list hosts by class:

hammer host list --search 'class=ntp’
API: GET “/api/hosts?search=class%3Dntp”

You can list classes by host:

hammer puppet_class list --search 'host=centos.mbacovsk.com|host=foremandevel.mbacovsk.com’
API: GET “/api/puppetclasses?search=host%3Dcentos.mbacovsk.com%7Chost%3Dforemandevel.mbacovsk.com”

Hi,

Thanks a lot :]
I’ve discovered hammer this week , I haven’t had time to try it but I will .

I wasn’t aware the api could be searched this way, thanks a lot I’ll try that to see what I can get with this !

Regards
