custom_script_files option doesn't seem to work

Hi there - I was trying to upload a script file to my vm using the custom_script_files option as follows:

    let myVm = vm {
        name vmResourceName
        username vmUsername
        vm_size Vm.Standard_B2s
        operating_system (Vm.makeLinuxVm "0001-com-ubuntu-server-focal" "canonical" "20_04-lts")
        os_disk 64 Vm.Premium_LRS
        diagnostics_support
        domain_name_prefix (Some vmHostname) 
        custom_script_files [ "https://gist.githubusercontent.com/blablabla/setup-vm.sh" ]
    }

but the script file URI doesn’t make it to the ARM template file.
Does it work only with Windows VMs…? Am I missing something?

(Thanks for Farmer btw, it’s a pretty handy project!)

If you’re happy with this error message i.e. it would have explained to you what to do, I’ll merge it in. https://github.com/CompositionalIT/farmer/pull/321/files#diff-d1f245ce5e20f91fe6c13181aac49db3R126

ok, thanks for the explanation! I’ll try again.

The reason why the two commands are separate is because you could simply pass the entire command in the custom_script rather than in files that you call.

makes sense. (I also got confused because if you search for “script to run upon deployment on Azure vm”, you find this page that talks about an inline script that has to be supplied base64 encoded…)

I’m going to add a validation error so that if you supply files but no script, we fail fast with a sane error message.

sounds good. I’d also suggest to expand a bit the docs (maybe add an ad-hoc example) (maybe I will submit a PR…).
