It won’t work like that because

bootstrap_storage_account_name

is also an

Output

You will want to invert where the

json.dumps

happens:

protected_settings=combined_output.apply(lambda lst: json.dumps({'storageAccountName': lst[0], 'storageAccountKey': lst[1]}))

how do I pass

combined_output

to a component?

You had

combined_output = Output.all(install_scripts_storage_account.name, install_scripts_storage_account.primary_access_key, install_scripts_storage_blob.url)

earlier

yeah, but that's in my

___main___.py

, the

protected_settings

is in a different file, a component, so I have to pass the

combined_output

to the component

Ah, I didn’t realize that. You can pass it any way you’d normally pass state between files in Python. For example, if the other file defines functions, one of which creates that component, and your

__main__.py

calls that function, you can pass it as an arg when calling that function.

interestingly, that's what I have done in my snippet above, just wasn't clear about the fact that the

compute.extensions

is part of the component and the

combined_output

is in the main. That's what threw the error I mentioned.

Gotcha. Were you able to get this working by having the

json.dumps

within the lambda?

I just tried this: `___main___.py`:

storage_information = [
  install_scripts_storage_account.name,
  install_scripts_storage_account.primary_access_key,
  install_scripts_storage_blob.url
]
vms = Compute("vms",
  ComputeArgs(
    resource_group_name=resource_group.name,
    vnet=network.vnet,
    public_subnet_id=network.public_subnet_id,
    storage_info=storage_information
  )
)

`component.py`:

class ComputeArgs:
  def __init__(
    self,
    resource_group_name: str,
    vnet: network.VirtualNetwork,
    public_subnet_id: str,
    storage_info: list
  ):
    self.resource_group_name = resource_group_name
    self.vnet = vnet
    self.public_subnet_id = public_subnet_id
    self.storage_info = storage_info

compute.Extension("{0}install".format(server),
        name="{0}install".format(server),
        virtual_machine_id=vm.id,
        publisher="Microsoft.Compute",
        type="CustomScriptExtension",
        type_handler_version="1.9",
        auto_upgrade_minor_version=True,
        settings=args.storage_info.apply(lambda lst: json.dumps({'commandToExecute': command_to_execute, 'fileUris': [args.bootstrap_file_name]})),
        protected_settings=args.storage_info.apply(lambda lst: json.dumps({'storageAccountName': lst[0], 'storageAccountKey': lst[1]}))
      )

This doesn't work, saying that

list

doesn't have an

apply

method. I believe I need to do the

apply

in the

main

, which I have tried, but that never worked.
