Looks good to me.

Does this still work with versions older than 1.7?

@rndmh3ro yes, it works with all Nomad versions above 0.8.x

Thanks, just tested it myself:

cat /tmp/test-nomad.yml
data_dir  = "/var/lib/nomad"

bind_addr = "0.0.0.0" # the default

advertise {
  # Defaults to the first private IP address.
  http = "1.2.3.4"
  rpc  = "1.2.3.4"
  serf = "1.2.3.4:5648" # non-default ports may be specified
}

server {
  enabled          = true
  bootstrap_expect = 3
}

client {
  enabled       = true
}

plugin "raw_exec" {
  config {
    enabled = true
  }
}

consul {
  address = "1.2.3.4:8500"
  tags = []
}
