  # We currently run these integration tests in two modes: one in which Envoy's
  # xDS sessions are served directly by a Consul server, and another in which it
  # goes through a client agent.
  #
  # This is necessary because servers and clients source configuration data in
  # different ways (client agents use an RPC-backed cache and servers use their
  # own local data) and we want to catch regressions in both.
  #
  # In the future we should also expand these tests to register services to the
  # catalog directly (agentless) rather than relying on the server also being
  # an agent.
  #
  # When XDS_TARGET=client we'll start a Consul server with its gRPC port
  # disabled (but only if REQUIRE_PEERS is not set), and a client agent with
  # its gRPC port enabled.
  #
  # When XDS_TARGET=server (or anything else) we'll run a single Consul server
  # with its gRPC port enabled.
  #
  # In either case, the hostname `consul-${DC}-server` should be used as a
  # server address (e.g. for WAN joining) and `consul-${DC}-client` should be
  # used as a client address (e.g. for interacting with the HTTP API).
  #
  # Both hostnames work in both modes because we set network aliases on the
  # containers such that both hostnames will resolve to the same container when
  # XDS_TARGET=server.
  #
  # We also join containers to the network `container:consul-${DC}_1` in many
  # places (see: network_snippet) so that we can curl localhost etc. In both
  # modes, you can assume that this name refers to the client's container.
  #
  # Any .hcl files in the case/cluster directory will be given to both clients
  # and servers (via the -config-dir flag) *except for* server.hcl which will
  # only be applied to the server (and service registrations which will be made
  # against the client).
