Modify vCMP-Guest with ansible not possible?

Hello Matt_Mabis ,

thank you for your answer.
I can confirm, that one can add VLANs to a vcmp-guest like this, but:

You have to list all the existing vlans next to the new one as well. You can't just add a new one. The module replaces all VLANs of the guest with the ones listed in the "vlans" section of the module.
I find this rather awkward. To add a VLAN to a guest, without knowing or careing what VLANs were configured previosly you had to:

1. Use module bigip_device_info to query information about all vCMP-guest on a vCMP-Host
2. Filter the output by the name of the vCMP-Guest you like to update and get the list of currently configured vlans
3. append the new vlan to the list
4. apply the extended list to the guest

vars:
  guest_to_modify: "Guest1"
  vlan_tobe_added: "/Common/fancy-new-vlan"

tasks:
  - name: Get vCMP-Guest Info
    bigip_device_info:
      gather_subset:
        - vcmp-guests
      provider: "{{ bigip_provider }}"
    register: device_info
    delegate_to: localhost

  - name: Filter for specific guest and build a list with new vlan
    set_fact:
      list_current_vlans: "{{ device_info.vcmp_guests|selectattr('full_path', 'match', guest_to_modify) | map(attribute='vlans') }}"
      list_with_added_vlan: "{{ list_current_vlans[0] + [vlan_tobe_added] }}"

  - name: Add VLAN to vCMP-Guest
    bigip_vcmp_guest:
      name: "{{ guest }}"
      vlans: "{{ list_with_added_vlan }}"          
      provider: "{{ bigip_provider }}"
    delegate_to: localhost

 Anyway. I tested it and it worked for me. the abillity to just add a new vlan would be better i guess, but I'll take it.

Thank you very much!
