How to fetch a specific IP via vmware_guest_info? - ansible

Question

I use vmware_guest_info: to get the DHCP address for my VMs. The problem is that after I have configured several static IP's, the guest.ipAddress is changed from the DHCP address, which is usually the first network adapter, to a randomly configured static IP:
---
- name: Gather a virtual machine info
vmware_guest_info:
hostname: '{{ vsphere_host }}'
username: '{{ vsphere_user }}'
password: '{{ vsphere_password }}'
validate_certs: false
datacenter: "{{ vsphere_datacenter }}"
name: "{{ hostname }}"
schema: vsphere
properties:
- guest.ipAddress
retries: 60
delay: 10
until: gather_vm_info.instance.guest.ipAddress is not none
register: gather_vm_info
delegate_to: localhost
- name: Gather a virtual machine info
vmware_guest_info:
hostname: '{{ vsphere_host }}'
username: '{{ vsphere_user }}'
password: '{{ vsphere_password }}'
validate_certs: false
datacenter: "{{ vsphere_datacenter }}"
name: "{{ hostname }}"
schema: vsphere
properties:
- guest.ipAddress
retries: 60
delay: 10
until: gather_vm_info.instance.guest.ipAddress != "0.0.0.0"
register: gather_vm_info
delegate_to: localhost
- debug: var=gather_vm_info.instance.guest.ipAddress
- debug: var=gather_vm_info
- name: "Update host_var with new IP Address"
set_fact:
ansible_host: "{{ gather_vm_info.instance.guest.ipAddress }}"
ansible_hostname: "{{ hostname }}"
This is what I get:

It looks like that VMWare assigned deviceConfigId: 4000 for the first Network Interface, but how can I access it on my Playbook?
debug: var=gather_vm_info.instance.guest.net[3].ipAddress[0]-?????
EDIT:
Can somebody explain, why vSphere register the IP address correctly for some VM's as guest.ipAddress and sometimes you have to get it as gather_vm_info.instance.hw_eth0.ipaddresses.
This would be fine, but in this example you can see that the IPAddress is only registered as gather_vm_info.instance.hw_eth0.ipaddresses and you don't get it as hw_eth0.ipaddresses???

Answer 1

IP Address of the first interface can get through the hw_eth0 property of the vmware_guest_info module result.
Here's the sample playbook.
---
- name: Example Playbook
hosts: localhost
gather_facts: false
vars:
hostname: test_vm2
tasks:
- name: Gather a virtual machine info
vmware_guest_info:
hostname: '{{ vsphere_host }}'
username: '{{ vsphere_user }}'
password: '{{ vsphere_password }}'
validate_certs: false
datacenter: "{{ vsphere_datacenter }}"
name: "{{ hostname }}"
register: gather_vm_info
- name: Display the first interface set IP Address of a virtual machine
debug:
msg: >-
{{ gather_vm_info.instance.hw_eth0.ipaddresses
| map('ipaddr', 'ipv4')
| select('!=', false)
| list
| first
}}
The hw_eth0 is the interface information of a virtual machine have.
If you want to get the second interface IP Address, change from hw_eth0 to hw_eth1.
The above playbook uses the ipaddr filter in getting only ipv4 address.
So it needs to install netaddr library.
(venv)$ pip install netaddr
By the way, the following playbook can be possible to get the first interface IP Address too.
---
- name: Example Playbook
hosts: localhost
gather_facts: false
hostname: test_vm2
tasks:
- name: Gather a virtual machine info
vmware_guest_info:
hostname: '{{ vsphere_host }}'
username: '{{ vsphere_user }}'
password: '{{ vsphere_password }}'
validate_certs: false
datacenter: "{{ vsphere_datacenter }}"
name: "{{ hostname }}"

- name: Set device_config_ids variable
set_fact:
device_config_ids: >-
{{ device_config_ids | default([])
+ [item.deviceConfigId]
}}
loop: "{{ gather_vm_info.instance.guest.net }}"
- name: Display the first interface set IP Address of a virtual machine
debug:
msg: "{{ item.1.ipAddress.0 }}"
with_nested:
- "{{ device_config_ids | sort | first }}"
- "{{ gather_vm_info.instance.guest.net }}"
when:
- item.0 | int == item.1.deviceConfigId
