Dealing with multiple backends

[michalmedvecky]

Hello

thank you for this comprehensive role.

I see in examples that you need to list all backends by hand in vars. What if I have dynamic inventory and want to add backends dynamically? Do you have some clever solution for this?

Thanks

Let me think about it. I'll get back to you.

I ended up with

{% for server in groups["all"] %}
{% if server in groups[backend.name] | default("") %}
      server {{ server }} {{ hostvars[server].ansible_ssh_host }}:{{ haproxy_backend.0.server.0.port }}{% for param in haproxy_backend.0.server.0.param | default([]) %} {{ param }}{% endfor %}

{% endif %}
{% endfor %}

in templates/etc/haproxy/backend.cfg.j2

I am not very happy about haproxy_backend.0.server.0.param, which I ignore in latter:

{% for server in backend.server | default([])%}
{% if server.name != "default" %}
  server {{ server.name }} {{ server.listen }}{% for param in server.param | default([]) %} {{ param }}{% endfor %}
{% endif %}
{% endfor %}

But works for me now.
