What does HackerNews think of constellation?

Constellation is the first Confidential Kubernetes. Constellation shields entire Kubernetes clusters from the (cloud) infrastructure using confidential computing.

Language: Go

#39 in Kubernetes
Constellation (a Kubernetes distro) [1] on Azure would give you this attestation feature. You could then run sth like HashiCorp's Vault in that cluster. You will know that all nodes of that cluster are in the state that you expect them to be through the attestation statement.
