Extra network interface for a Cephfs setup

[poquirion]

For perfomance/traffic optimization, we will have a cephfs deployment on a separate network in openstack. This mean that a second network will need to be attatche to login, compute and dtn nodes. I guess that this part all need to be done in this repos, not the puppet one.

I envision this as a config that would look like

subnet_id = {
main = <id>
secondary = <id>
}

or

subnet_id =  <id>
secondary_subnet_id =  <id>

or something else....

There is less refactoring the second case, but the first config looks better to me.

Once that is done, the puppet part of mounting cephfs will be the same since selecting the right internal ip address will make the cephfs client use of the right interface.

A potential for this issue was to drop in the openstack folder a Terraform file that would contain the following:

resource "openstack_networking_port_v2" "nic_ceph" {
  for_each           = module.design.instances
  name               = format("%s-%s-ceph-port", var.cluster_name, each.key)
  network_id         = "00b327b4-4fb2-4ed8-a7f2-6ff49e3b7e7c"
  security_group_ids = concat(
    [
      openstack_networking_secgroup_v2.global.id
    ],
    [
      for tag, value in openstack_networking_secgroup_v2.external: value.id if contains(each.value.tags, tag)
    ]
  )
}

resource "openstack_compute_interface_attach_v2" "extra_network" {
  for_each    = module.design.instances_to_build
  instance_id = openstack_compute_instance_v2.instances[each.key].id
  port_id     = "openstack_networking_port_v2.nic_ceph[each.key].id"
}

The file has to be put next to the other openstack module files because the Magic Castle provider modules do not output the ids of the instances nor the ids of the security groups. Otherwise, you would have been able to create these ressources outside of the openstack module.

I added this:

     1	resource "openstack_networking_port_v2" "nic_ceph" {
     2	  for_each           = module.design.instances
     3	  name               = format("%s-%s-ceph-port", var.cluster_name, each.key)
     4	  network_id         = "00b327b4-4fb2-4ed8-a7f2-6ff49e3b7e7c"
     5	  security_group_ids = concat(
     6	    [
     7	      openstack_networking_secgroup_v2.global.id
     8	    ],
     9	    [
    10	      for tag, value in openstack_networking_secgroup_v2.external: value.id if contains(each.value.tags, tag)
    11	    ]
    12	  )
    13	}
    14	
    15	resource "openstack_compute_interface_attach_v2" "extra_network" {
    16	  for_each    = module.design.instances_to_build
    17	  instance_id = openstack_compute_instance_v2.instances[each.key].id
    18	  port_id     = "openstack_networking_port_v2.nic_ceph[each.key].id"
    19	}

and here is the error I get

mmm, I see the weirdly placed quotes now.
