I have a setup of 3 nomad / consul servers and 3 nomad / consul clients. Connect block to provide service mesh is enabled on consul servers. Now Im working on implementing TLS on consul agents. With this i figured out that Im facing a lack of knowledge of basics, how communication between nomad client/server and consul client/server works. In case of service mesh i can see that nomad agents are registered as a services in consul. Does it mean that the communication between this ,services" (nomad servers and clients) is by default encrypted with built-in TLS of consul service mesh? Is there a need of implementing TLS in nomad cluster?
