Hello!

We are trying to use Playbook without the guest customization at first, but are encountering error we cant seem to find a solution.

Playbook:

• name: Provision some VMs
  hosts: localhost
  gather_facts: false
  vars:
  my_vms:
  - {vm_name: 'test', vm_ip: '10.0.0.0', vm_ram: 2048, vm_num_cpu_per_socket: 1, vm_num_sockets: 4, vm_disk_list: [disk_size_mib: 10000]}
  tasks:
  • name: Provision VMs on Nutanix
    include_role:
    name: nutanix
    vars:
    vm_defs: "{{ my_vms }}"

Removed the following lines from vm-body.yml.y2:
guest_customization:
cloud_init:
user_data: {{ lookup('template','cloud-init.yml.j2') | b64encode }}

Error is following:
TASK [nutanix : Debug | Print VM definitions] *********************************************************************************************************************************************************************************************************************

I've tried examining the API for creating a VM from the explorer on my Nutanix cluster, however several of the fields in vm-body.yml.j2 and the official field names in the REST API explorer are different, for example "nic_list" in the j2 file and "vm_nics" on the REST API explorer. I've attempted to include the storage_container_uuid: "string" in the vm-body.yml.j2 file and received the following error. We're trying to place the disks within a container that has compression and EC enabled and would really rather not use the default container with edits made to it's config. Any help would be appreciated, below is the contents of my vm-body.yml/j2 file.

We are getting an error at the Stash the image task. Can you advice what is the purpose of default([])? from our understanding it seems that you are trying to set the variable image_uuids to the result of query: default([]) + [ {'name': item.spec.name, 'uuid': item.metadata.uuid but please correct me if I am wrong. I am trying to see if I can write another query to get the value and define the variable

Error:
fatal: [nutanixserver]: FAILED! => {"msg": "Unexpected templating type error occurred on ({{ image_uuids | default([]) + [ {'name': item.spec.name, 'uuid': item.metadata.uuid } ] }}): can only concatenate str (not "list") to str"}

• name: Stash the image UUIDs
  set_fact:
  image_uuids: "{{ image_uuids | default([]) + [ {'name': item.spec.name, 'uuid': item.metadata.uuid } ] }}"

Hi, thanks for creating this role ! I am currently testing and had a question. In the playbook you have in the example you list localhost, when I try on mine I can see:

TASK [nutanix_provisioner : Auth to the cluster] ********************************************************************************************************************************************************************************************
fatal: [localhost]: UNREACHABLE! => {"changed": false, "msg": "Authentication or permission failure. In some cases, you may have been able to authenticate and did not have permissions on the target directory. Consider changing the remote tmp path in ansible.cfg to a path rooted in "/tmp". Failed command was:

So I changed the localhost to an inventory list that has my NTNX cluster IP but failed to auth.

• Are there any configs to be done on the NTNX side like adding ssh keys?
• Are you running the roles inside the NTNX server?

Thanks!

Hi Matt,

Getting an error when it gets to the task: Create fact with VM template. I'm also using python 3 as when I researched the error some people stated that python 3 removed dict.iteritems

ACTUAL RESULTS

TASK [nutanix_provisioner : Create fact with VM template contents] **************************************************************************************************************************************************************************

fatal: [10.71.30.80]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'iteritems'\n\nThe error appears to be in '/etc/ansible/roles/nutanix_provisioner/tasks/provision_vm.yml': line 11, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Create fact with VM template contents\n ^ here\n"}
