HI,

We just upgraded from consul 1.6.4 to 1.9.1 and caravan is not working anymore with this error :

11:04:27.414 [warn]  [libcluster:caravan] unable to connect to :"[email protected]_de_1.consul"
11:04:34.418 [warn]  [libcluster:caravan] unable to connect to :"[email protected]_de_1.consul"
11:04:39.423 [error] 
** Cannot get connection id for node :"[email protected]_de_1.consul"

I have done some digging on the consul side and found they have changed the SRV response format hashicorp/consul#7360 and hashicorp/consul#7360

Instead of returning the node fqdn app-10-62-21-91.node.dev-eu_de_1.consul. it's returning this 0a3e172b.addr.dev-eu_de_1.consul.

And it broke Caravan.

Hello,

I was trying to connect to a running node.
I'm connected in the container and I tried to run the remote_console (of distillery release) but it keep saying that the node isn't running.

How can I connect to it when using Caravan with Consul DNS?

I can't find any solution by my own.

THank's!

Something like:

defmodule :caravan_dist do
  # …
end

would greatly improve readability of command line arguments.

I receive this error only with the --sname flag. without this flag no error occur ...
I use Elixir 1.7.3 and Erlang 21

Hello again! Wondering if you could help me debug my installation. Here is the configuration I've added to prod.exs:

config :libcluster,
  topologies: [
    caravan: [
      strategy: Caravan.Cluster.DnsStrategy,
      config: [
        query: "pangea.service.bowery",
        node_sname: "pangea",
        poll_interval: 5_000,
        dns_client: Caravan.DnsClient
      ]
    ]
  ]

When I ssh to a running instance of the service and dig pangea.service.bowery, I get the expected list of 4 IP addresses (this service is running on 4 nodes). But when I ssh to the node, open an iex session and run Node.list(), it returns an empty list, which makes me think it's not finding the other nodes. How should I go about debugging this? I don't see anything in our logs related to caravan or libcluster. How should I interrogate our installation to better understand where it's failing? Any help is much appreciated, thank you! Apologies in advance if this request is too vague - I can close it out if I'm barking up the wrong tree.

Hello! I am trying to integrate caravan into our service so that I can deploy it to our nomad/consul cluster. Thanks for this great library. I added {:caravan, "~> 1.0.0"}, to mix.exs and ran mix.deps get. But when I try to compile, I get this error:

$ mix deps.compile caravan
==> caravan
Compiling 8 files (.ex)

== Compilation error in file lib/caravan/cluster/dns_strategy.ex ==
** (CompileError) lib/caravan/cluster/dns_strategy.ex:52: module Cluster.Strategy is not loaded and could not be found
    (elixir) expanding macro: Kernel.use/1
    lib/caravan/cluster/dns_strategy.ex:52: Caravan.Cluster.DnsStrategy (module)

I also tried explicitly adding {:libcluster, "~> 3.2.1"} to mix.exs and confirmed that libcluster was in my deps directory, but I still got the same error when I try to build the app or run mix deps.compile caravan. Any ideas?
