With_items /pass var - string.

[Adam McGill]

I would like to take the value of the var and pass it into with_items and I am running into an issue / error, how can i pass just the value into with_items.  If i hardcode and put the value with_items: {{ small2019 }} in there are no issues.  Using include_vars / file which has the data, want to pass value into with items to get results.

Result:

************************************

- debug:

    var:  "{{ 'vm_config' }}"

okL  [(servername)] => {

  "vm_config": "small2019"

}

Using with_items with value, errors

********************************************

- name: Create VMs

  win_hyperv_guest:

    vmname: "{{ vm_name }}"

    hvhostname: "{{ hv_fullname }}"

    installmedia_source: "{{ item.InstallMedia.Source }}"

    installmedia_destination: "{{ item.InstallMedia.Destination }}"

    importvmoptions_path: "{{ item.ImportVMOptions.Path }}"

    importvmoptions_destination: "{{ item.ImportVMOptions.Destination }}"

    systemosdisksize: "{{ item.SystemOSDiskSize | default (omit) }}"

    vmmemory: "{{ item.VMMemory }}"

    vmprocessor: "{{ item.VMProcessor }}"

    vmnetworkadaptervlan: "{{ item.VMNetworkAdapterVlan }}"

    vmnetworkadapter: "{{ item.VMNetworkAdapter | default (omit) }}"

    additionaldisks: "{{ item.AdditionalDisks | default (omit) }}"

    failoverclusteradd: "{{ item.FailoverClusterAdd | default (omit) }}"

    removedvdrive: "{{ item.RemoveDVDrive | default (omit) }}"    

    bootordergen2networklast: "{{ item.BootOrderGen2NetworkLast | default (omit) }}"

    state: present

  with_items: "{{ 'vm_config' }}"

  register: new_vms

Using with_items with hardcoded - works

Why did you wrap the variable in single quotes? This makes it a literal string instead of the contents of the variable ...

If i remove the single quotes, in the debug i see it pull the information correctly from the include_vars.  If I use the same with_items: "{{ vm_config }}" in the task i get this.

"msg": "The task includes an option with an undefined variable. The error was: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'InstallMedia'\n\nThe error appears to be in

Basically i have a include_vars file that has all my configs, want with_items to only pull back the required config.  

example / include_vars:

---

small2019:

  - config: "DC2019"   

    InstallMedia:

      Source: "\\\\someshare\\"

      SourceVHDX: "Virtual Hard Disks\\DC2019.vhdx"

      Destination: "C:\\ISOs\\MDT\\DC2019\\"

large2019:

  - config: "DC2019"   

    InstallMedia:

      Source: "\\\\someshare\\"

      SourceVHDX: "Virtual Hard Disks\\DC2019.vhdx"

      Destination: "C:\\ISOs\\MDT\\DC2019\\"

All the looping constructs (with_items etc) assume you have some data
structure that is iterable, ie. a list, a dict, etc.
From your vars file it seems (guessing here) that you want to iterate
over multiple independent variables.
If that is the case, I would suggest restructuring those multiple vars
to one iterable var.
This will give you a lot more flexibility elsewhere in your deployment as well.

For example:

allsizes:
- config: "DC2019"
name: small2019

InstallMedia:
Source: "\\\\someshare\\"
SourceVHDX: "Virtual Hard Disks\\DC2019.vhdx"
Destination: "C:\\ISOs\\MDT\\DC2019\\"

- config: "DC2019"
name: large2019

InstallMedia:
Source: "\\\\someshare\\"
SourceVHDX: "Virtual Hard Disks\\DC2019.vhdx"
Destination: "C:\\ISOs\\MDT\\DC2019\\"

(Note that apart from the name (which used to be your variable name),
the dicts are exactly the same - I guess this is just example data and
in reality these actually differ)


If this is now what you want, then explain better what you do want. I
would help if you provide real world examples.

Thanks for the reply Dick.

Basically i want to have a include file/vars that will hold configuration items for each config.  Using with_items would like to call out to that config file/include vars and pull only the data associated to its name.  The information i provided, yes was an example and I think your reply of the restructuring could help.  Based on using that restructure using with_items is going to loop in all the information in the config/include file. So i could narrow down my list in within the with_items with a passed extra vars variable ( {{  allsizes.{{ vm_config }} }}  ?  Going to test out / restructure this afternoon , sorry for the delay in response, appreciate the feedback.
