Issues on ipv6-only hosts

[iojcde]

I'm having issues setting up consul on ipv6-only hosts.

I've specified consul_iface in the playbook, but it doesn't seem to work for some reason.

---
# File: site.yml - Example nomad site playbook
- name: Assemble Consul cluster
  hosts: masters
  any_errors_fatal: true
  become: true
  become_user: root
  roles:
    - ansible-consul
  vars:
    consul_group_name: masters
    consul_iface: eth0
    consul_node_role: server 
    consul_bootstrap_expect: true

I'm very new to ansible, so it might be something I did wrong.

If I'm understanding correctly, shouldn't consul_bind_address be configured to the address of the interface in consul_iface by default?

Edit: seems like #40 is kinda related

Just ran across this, the project hard-codes 'ipv4' in its default for consul_bind_address. You can define your own address instead
eg

    consul_bind_address: "{{ ansible_facts['ens18']['ipv6'][0]['address'] }}"
