Have you played with anything like Istio to secure in-cluster communications? I think Hashicorp Consul can do something similar to encrypt service to service communications.
I looked into it but I felt at the time it was too complex, maybe I’ll look at it again. Currently I am using wireguard for all cluster node-to-node traffic. It seemed like a reasonable tradeoff at the time, but it is at the network layer instead of application, so I really should revisit that at some point.
That makes sense!

Yeah it very adds some extra complexity and it’s more important for if you are hosting in public clouds anyways IMO.
