vRA 8.6 | How to add "requesting" User to local Admin Group

Hello, 

First of all all thanks everyone for your feedback on this one...

We have been looking for different ways to get the vRA requesting user added to the local admin group for Windows and Linux VMs. One way to do that is by using Cloud-Init/Cloud-base and the use of  "env.requestedBy" the for example in Windows we can then use Powershell to get the user in the local admin group.  

Since we are using Ansible to join the Windows VMs into the domain and do everything else needed via playbook we can not use this approach because Cloud-Base will run before the Ansible playbook will be executed which means that the machine will not be in the domain yet. 

I was wondering if someone has some ideas on how to do this using Ansible. I am not sure if there is a way to use "env.requestedBy" somehow in Ansible so we can then add the user as part of the local Administrator group in one of the the steps of the playbook once the VM is added to the domain. 

Otherwise is there a way within the blueprint to change the order so the ansible playbook is completed first and then run the Cloud-base/Cloud-init commands afterwards to add the env.requestedBy user to the local admin group? 

Any help here would be greatly appreciated. 

Thank you!

Hey, on the Ansible side of things I would suggest you have a look at using something like this.

If you need to pass information I suggest looking at HostVariables, to pass info from the yaml to ansible. There is a good example in the official documentation that can be read here.

Hope this helps!

Thanks Paul, 

For testing I've been trying to the following:

- name: Add a local and domain user to a local group
ansible.windows.win_group_membership:
name: Remote Desktop Users
members:
- NewLocalAdmin
- mytestdomain\"{{ reqUser }}"

state: present

in the blueprint I had defined the following var 

hostVariables: |

reqUser: '$(env.requestedBy}'

From what I found requestedBy is vRA var that's contains the user that's performing the request. 

When I run the the Cloud Template / blueprint I get syntax error. 

Any ideas what can be wrong here? Might be something with - mytestdomain\"{{ reqUser }}

Thank you so much!

Have you tried it without the quotes? Is your spacing correct? the reqUser line needs to be indented. If your yaml formatting isnt correct then it wont work. Have you tried the example I linked you to in my last reply? Does that example work ok?

hostVariables: |

  reqUser: $(env.requestedBy}

Hello, 

For some reason the variable requestedBy is seen by ansible like this there isn't a user value to it.

"msg": "$(env.requestedBy}"
}

I am not sure if I am doing something wrong, or requestedBy isn't working. Ultimately all I want to do is to pass the requestedBy, the user that requested the deployment as a member of the local administrator group using ansible. If I use the example you've provided and get the DOMAIN\user statically this the deployment and the ansible playbook work as expected. 

I've also noticed that in the Deployment/Topology the message I do with the variable is picking up the correct user, but the other ones comes as  reqUser: $(env.requestedBy}
