Enabling Gossip Encryption in Nomad
By default, Nomad does not use any encryption between the agents running in Server mode. Encryption is available however, and can be enabled fairly easily. In this hands-on lab, you are provided with three servers built out as Server Agents, that are part of the same cluster. Your task is to enable Gossip encryption between the servers. Once enabled, you should still be able to see all three servers, and they should be able to continue to work together in the cluster.
