Subject Re: stateless solr ?

Are you using Solrcloud? With Solrcloud this stuff is easy. You just add
a new replica for a collection, and the data is added to the new host.

I'm working on a demo that will show this all working within Docker and
Rancher. I've got some code (which I will open source) that handles
config uploads, collection creation, etc. You can add a replica by
running a container on the same node as you want the replica to reside,
it'll do the rest for you.

I've got the Solr bit more or less done, I'm now working on everything
else (Dockerised Docker Registry/Jenkins, AWS infra build, etc).

Let me know if this is interesting to you. If so, I'll post it here when
I'm done with it.
