I am playing with MaaS in a vSphere environment so I can simulate large clusters. I have finished my auto-provisioning PowerShell script, where I can provision a bunch of virtual machines to be added to the MaaS controller. I can add these nodes manually in the Controller GUI and I was able to commission them accordingly. I'm currently trying to figure out how to add the machines via the MaaS CLI, and I'm stuck on the power_parameters parameter. Based off the MaaS API documentation, I have to add everything as a key=value type.

Where I'm stuck is on how to add that parameter in the CLI. If I don't pass power_parameters, I get this error:

400 BAD REQUEST



       Content-Type: application/json; charset=utf-8

{"power_parameters": ["This field is required."]}

But I cannot figure out the proper string formatting for the parameter. I have tried several combos:

# tried adding it as a string as the docs say

maas <user> machines create -d 

  ... 

  power_parameters="power_vm_name=<vmname> power_uuid=<vmuuid>"



# tried query string separating

maas <user> machines create -d 

  ... 

  power_parameters="power_vm_name=<vmname>&power_uuid=<vmuuid>"



# tried comma separating

maas <user> machines create -d 

  ... 

  power_parameters=power_vm_name=<vmname>,power_uuid=<vmuuid>



# tried individual parameters

maas <user> machines create -d 

  ... 

  power_vm_name=<vmname> power_uuid=<vmuuid>

I get this error with every permutation I've tried:

400 BAD REQUEST

Failed to parse JSON power_parameters

I know I can send the raw JSON payload via REST, but I don't really want to implement a REST client in PowerShell for MaaS.

What is the proper string formatting for adding power_parameters in the MaaS CLI?

So, I ripped apart the MaaS CLI code base, and I saw lots of references to power_parameters_<param> in the code base, which led me to believe it's looking for a specific key formatting.

This is what ended up working for me:

maas <user> machines create -d \

    architecture=amd64 

    mac_addresses=<mac> 

    domain=<domain> 

    hostname=<name> 

    power_type=vmware 

    power_parameters_power_vm_name=<vm_name> 

    power_parameters_power_uuid=<vm_uuid> 

    power_parameters_power_address=<vcenter_host_name> 

    power_parameters_power_user='<maas_user_in_quotes>' 

    power_parameters_power_pass='<password_in_quotes>' 

    power_parameters_power_port=443 

    power_parameters_power_protocol=https+unverified

I was then able to see the machine in the Controller UI.
