I have an install of ASDK v2002.35 for the purpose of studying for my Azure Administrator certifications. I also used Matt Mcspirit's Azure Stack POC Configurator to install additional services. Overall all works as expected, but while attempting to deploy Custom Script for Linux extension via Portal and ARM Template I'm getting errors which appears to be due to the untrusted certificates.
PORTIONS OF ERROR MESSAGE:
(Enable failed: processing file downloads failed: failed to download file[0]: failed to download file: http request failed:)
(x509: certificate signed by unknown authority)
I was able to remediate the issue by manually importing the AzureStackSelfSignedRootCert into a Linux VM. Then, I could deploy other scripts without error.
FYI: Why are there not more extensions made available to the ASDK (KeyVault Extension)? Likewise features natively made available, but do not work (metrix/monitoring)?
My apologies for the delay on responding to this one.
This error appears when the custom script extension is run on the VM, but the VM is not able to download the file from the location you specified. There are many ways to specify the file to run, typically it is uploaded to an Azure Storage account first, and then is downloaded with a SAS URL. If the script is small, you can also pass it directly in the command.
Where was the file you passed with the custom script extension?
There are some extensions that are explicitly not allowed in the ASDK. The ASDK is for development purposes only, and some functionality of Azure or Azure Stack Hub is not part of the ASDK, like monitoring and some key vault elements.
It's been 9 days since my writing this post and no one has offered assistance. I will not let it die!
