Enabling TLS for a Consul Cluster

In this hands-on lab, you will enable TLS encryption on a 3 node cluster. You will be provided with three server agents that are already part of a cluster in the dc1 datacenter. You will need to create the CA (Certificate Authority) and the certificates for the server agents. Then configure each of the server agents to use TLS with the certificates you created. Finally, you will then test to ensure TLS is working between the server agents.
