Description

In the wikidata-dev project, any instance whose name begins with “wikibase” automatically gets role::wikibase applied. This role seems to be broken in some way, according to this output in the instance log:

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Error while evaluating a Function Call, Could not find data item profile::microsites::wikibase::server_name in any Hiera data file and no default supplied at /etc/puppet/modules/profile/manifests/microsites/wikibase.pp:3:18 on node wikibase-test-t225307.wikidata-dev.eqiad.wmflabs

The effect of this is that you can’t SSH into the instance because Puppet doesn’t finish. Workaround: give your instance some other name (assuming you don’t need role::wikibase).

I tried this out by creating other-test-T225307 and wikibase-test-T225307 instances; other-test-T225307 worked fine, wikibase-test-T225307 doesn’t. (I’m deleting other-test-T225307 now, but wikibase-test-T225307 can stay around for a bit, in case someone wants to investigate it further.)

I wouldn't say that the role is necessarily broken; it may just be that it needs the hiera args provided if the class is applied. You could provide a good default in the git puppet tree, though, if there is a good universal default. Easier would be to just add it to the project-wide hiera setting on Horizon.

Okay, I think I’ve figured out the most important parts. Basically, you don’t want to name your instance wikibase-something; however, if you do, I’ve now set some default config that at least lets you SSH into the instance, and added some documentation at https://wikitech.wikimedia.org/wiki/Nova_Resource:Wikidata-dev/Documentation#wikibase*.

@Andrew I don’t think there are good defaults for those parameters, though (perhaps for the server admin, but not for the server name), so I’d leave the puppet git tree as it is.
