Important Info - cert-chain.pem is Envoy’s cert that needs to be presented to the other side. key.pem is Envoy’s private key paired with Envoy’s cert in cert-chain.pem. root-cert.pem is the root cert to verify the peer’s cert. In this example, we only have one Citadel in a cluster, so all Envoys have the same root-cert.pem.
