Hi guys. Currently I’m building infrastructure for an app that I’m developing, it looks something like this: There is a hub cluster which hosts Hashicorp Vault, Cloudflared(the tunnel) and Karmada(which I’m going to replace soon with Flux’s Hub and Spoke) Then there is region-1 cluster which connects to the hub cluster using Linkerd. The problem is mainly with linkerd mc, altho it serves it’s purpose well it also adds a lot of sidecars and whatnots into the picture and surely enough when I scale this into a multi-region infrastructure all hell will break loose on every cluster, since every cluster is going to be connected to every other cluster for cross regional database syncs(CockroachDB for instance supports this really well). So is there maybe a simpler solution for cross-cluster networking? Because from what I’ve researched it’s either create an overlay using something like Nebula(but in this scenario there is even more work to be done, because I’ll have to manually create all endpoints), or suffer further with Istio/Linkerd and other mc networking tools. Maybe I’m doing something very wrong on design level but I just can’t see it, so any help is greatly appreciated.
