I am facing an issue while running my ansible-playbook to filter out the IP address from the playbook output. Here is my code

- hosts: myhost
  tasks:
    - name: Gather all VMs from a specific folder
      community.vmware.vmware_vm_info:
        hostname: myhost.com
        username: local
        password: mypass
        folder: "/VMFStorage/vm/"
        validate_certs: False
      delegate_to: localhost
      register: vm_info
    - debug:
        var: vm_info

The output of the code

ok: [myhost] => {
    "vm_info": {
        "changed": false,
        "failed": false,
        "virtual_machines": [

                    }
                }
            },

The required output is to catch the IP address of Machine1 guest name and print that output

192.168.1.29

I tried many possibilities but couldn't find out the proper solution Any help would be appreciated

try this.. if you only want machine1 ip_address.

    - debug:
        msg: {{ vm_info.virtual_machines[1].ip_address }}

try this.. if you only want all VMs ip_addresses.

    - debug:
        msg: {{ vm_info.virtual_machines[*].ip_address }}

CodePudding user response：

There are many options. For example,

1. Select the dictionary from the list first and extract the attribute

    - debug:
        var: ip
      vars:
        ip: "{{ vm_info.virtual_machines|
                selectattr('guest_name', 'eq', 'Machine2')|
                map(attribute='ip_address')|first }}"

gives

  ip: 192.168.1.29

2. If you prefer json_query the task below gives the same result

    - debug:
        var: ip
      vars:
        ip: "{{ vm_info.virtual_machines|
                json_query('[?guest_name==`Machine2`].ip_address')|first }}"

3. Create a dictionary first if there are many items on the list that should be referenced, e.g.

    - debug:
        var: name_ip
      vars:
        name_ip: "{{ vm_info.virtual_machines|
                     items2dict(key_name='guest_name', 
                                value_name='ip_address') }}"

gives

  name_ip:
    Machine2: 192.168.1.29
    RHEL Machine: 192.168.1.47

Then, use this dictionary to get the IP of a guest. The task below also gives the same result

    - debug:
        var: ip
      vars:
        ip: "{{ name_ip['Machine2'] }}"
