I need help creating a dynanic inventory within a playbook with the following information returned by the URI module:

```auto
{
	"3ed941bc_136b_40bf_9614_4ea3cd0a13e5": {
		"hosts": [
			"host1.example.com",
			"host2.example.com"
		]
	},
	"_meta": {
		"hostvars": {
			"host1.example.com": {
				"hostname": "host1",
				"domain": "example.com",
				"virtualization": {
					"isVirtual": true,
					"guest_name": "MyGuest",
					"type": "vmware",
					"datacenter_name": "MyDataCenter",
					"folder_name": "MyFolder"
				},
				"patching": {
					"ppsa": false,
					"excludedPackages": [
						"ep1",
						"ep2",
						"ep3"
					]
				},
				"enabledChannels": [
					"ch1",
					"ch2",
					"ch3"
				],
				"managedServices": [
					"ms1",
					"ms2",
					"ms3"

				"skipFinalReboot": false,

			},
			"host2.example.com": {
				"hostname": "host2",
				"domain": "example.com",
				"virtualization": {
					"isVirtual": true,

You’ve not said what exactly you need help with. What would also be helpful is to know why you want to do this. (tbh it sounds a bit strange to me wanting to create an Ansible dynamic inventory from a playbook)

You may also want to look at the `add_host` module which permits adding a hosts / groups to inventories for later plays in the playbook

That is the format expected for the ansible.builtin.script inventory plugin [ansible.builtin.script inventory – Executes an inventory script that returns JSON — Ansible Community Documentation](https://docs.ansible.com/ansible/latest/collections/ansible/builtin/script_inventory.html). You could create an executable file that prints the json.

```auto
    - name: Create inventory script
      copy:
        content: |
          #!/bin/bash
          echo '{{ result.content | to_json }}'
        dest: /path/to/inv.sh
        mode: '0755'

```

And then validate it works with ansible-inventory:

`ansible-inventory -i /path/to/inv.sh --list`

solved.

```auto

      uri:
        url: "http://servera/pub/{{ session }}"
        method: GET
        return_content: yes
      register: loaded_info

    - name: debug loaded info
      set_fact:
        my_inv: "{{ loaded_info.content| from_json }}"

    - name: Create inventory
      add_host:
        name: "{{ item.key }}"
        groups: patching_hosts
        ansible_host: "{{ item.key }}"
        ansible_hostname: "{{ item.value.hostname }}"
        pcs_sid: "{{ item.value.patching.pcs_sid }}"
        domain: "{{ item.value.domain }}"
        virtualization: "{{ item.value.virtualization }}"
        patching: "{{ item.value.patching }}"
        enabledChannels: "{{ item.value.patching.enabledChannels }}"
        managedServices: "{{ item.value.patching.managedServices }}"
        skipFinalReboot: "{{ item.value.patching.skipFinalReboot }}"
        doSnapshot: "{{ item.value.patching.doSnapshot }}"
      loop: "{{ my_inv['_meta']['hostvars'] | dict2items }}"
