Running a Sync Gateway Cluster Under CoreOS on AWS

[Traun Leyden]

I just wrote up a blog post which walks through how to run a 3 node Couchbase Server + Sync Gateway cluster on AWS:

http://tleyden.github.io/blog/2014/12/15/running-a-sync-gateway-cluster-under-coreos-on-aws/

Also it covers firing up more Sync Gateway nodes and setting up an Elastic Load Balancer.

This is really great. It would be nice to also have support for using Nginx for load balancing as well since ELB seems to have issues with SG.

Hey Todd,

Great feedback, and I would have done it in the first pass if it wasn't for the complexity involved.

Luckily Andy Reslan has written up a guide on that:

http://developer.couchbase.com/mobile/develop/guides/sync-gateway/nginx/configuring-nginx-for-sync-gateway/index.html

and at some point I will loop back around and fold this into the deploy script.

Can you give details about the issues you are seeing with ELB?

ELB does not support CBL long polling. It drops the connection after 1 min.

The iOS replicator will use WebSockets; do those work properly?

On other platforms this can be worked around on the client side by setting the _changes feed's heartbeat to 45 seconds or so. To do this, set the replicator option "heartbeat" to 45000, via Replication.customProperties or from the REST API just adding that property to the JSON body.
