If we keep the Telemeter as the auth proxy around, that is running in front of Observatorium, and this is for Telemeter auth, then this memcached deployment should go there. What do you think?

[squat]

Definitely not against that approach either :) we can close this and move it there. My rationalization was that it’s not a requirement of telemeter but rather an optimization of the usage, so it didn’t need to be the default. Though it could also be made optional with a jsonnet config value

[bwplotka]

LGTM, but it's the good question about the actual deployment place.

I like it as we plan to lean heavily on Memcached for Store GW at some point as well, so this might come handy. (:

[metalmatze]

We discussed to move this to another repo. It's unrelated to Observatorium itself.

Closing in favor of the new commit in openshift/telemeter#273
