CirrostratusModify vCMP-Guest with ansible not possible?
Hello fellow F5ers, I try to build an ansible playbook that performs the following: Get Names of trunk from vCMP-Host -> got it by using module bigip_device_info Create a new VLAN and add it to ...
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:- Use module bigip_device_info to query information about all vCMP-guest on a vCMP-Host
- Filter the output by the name of the vCMP-Guest you like to update and get the list of currently configured vlans
- append the new vlan to the list
- 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: localhostAnyway. 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!

EmployeeHey there Ichnafi!
I Tested code out for myself and got it working with bigip_vcmp_guest, here is the code i used you can see the first and second tasks creates 2 VCMP Guest Instances and the 3rd task of code modifies the existing created VCMP Guest, no ping loss no packet drops from my testing.

Totally understand where you are coming from, I think they would have had to create a different module for that scenario. The removal of a vlan would have created complications against bigip_vcmp_guests module as a "absent" status trying to remove a vlan would probably tell the system to remove the entire guest not just a vlan..
Glad you were able to figure out a solution.
