I'm trying to modify the json public_ip_allocation_method value using json_modify.py.

But I get the following error:

"msg": "member '' not found in {'name': 'Ubuntu915', 'private_ip_address': '10.0.0.5', 'private_ip_allocation_method': 'Dynamic', 'primary': True, 'load_balancer_backend_address_pools': None, 'application_gateway_backend_address_pools': None, 'public_ip_address': '/subscriptions/123456/resourceGroups/test-rg/providers/Microsoft.Network/publicIPAddresses/Ubuntu-915-test', 'public_ip_allocation_method': None, 'application_security_groups': None}" }

Playbook:

  - name: Get facts for one network interface
    azure_rm_networkinterface_info:

      name: "{{ azure_vm_network_interface }}"

    set_fact:
      mydict: {
               'public_ip_allocation_method': 'Dynamic', 
               }

      pointer: "/networkinterfaces/0/ip_configurations/0/"

      update "{{ mydict }}"
    register: result

CodePudding user response：

following the documentation of jsonpointer,

you have to write:

pointer: "/networkinterfaces/0/ip_configurations/0"

and not

pointer: "/networkinterfaces/0/ip_configurations/0/"
