Hi all, does anyone know if there’s a way to run a cluster of spicedb instances using something like ECS? I can start one instance fine; but how does the clustering stuff work behind the scenes?

Hi 👋 SpiceDB does cluster Dispatch by leveraging the Kube API Server to discover other SpiceDB instances, essentially reading the list of endpoints for a given Service, if I recall correctly. There is also support for discovery via XDS. Unfortunately I'm not aware (i.e. we haven't spent time on it) of a way to do dispatching our of the box on ECS. You could use whatever API they expose for service discovery, but it won't be plug and play.

They do have “cloud map” which updates dns automatically when new tasks are spun up in a specific cluster.

Yes but it may cause some failures while the DNS is updating

As in; permission lookup failures?

Dispatch, but yes

hi! just wondering, did you get this to work?

we are not aware of folks doing cluster dispatch on ECS - AWS has a special API for this, and it would at the very least modify SpiceDB to support it.

@edulop haven't had time to implement yet. Will let you know if I do.

thank you!

Hey guys, I looked briefly into how to support ECS. Would using AWS CloudMap for service discovery be a viable option for y'all?

@vroldanbet yeah; we use cloud map - that would be a great option.

Actually it's not much better than the DNS resolver, you'd still get failures as nodes come and go
