Demo

Here's a demo of this being used: https://asciinema.org/a/euXb9dIeUybE3VkstLWLbvhmp

Usage

This is meant to be an example image that you can copy into your own project and modify to your own needs. Notice that the example image includes a built-in test user account, which by default uses your ~/.ssh/id_ed25519.pub as an authorized_key.

Build and upload the image

$ ./upload-image.sh ./examples/basic/image.nix

...
+ attr=azbasic
+ nix-build ./examples/basic/image.nix --out-link azure
/nix/store/qdpzknpskzw30vba92mb24xzll1dqsmd-azure-image
...
95.5 %, 0 Done, 0 Failed, 1 Pending, 0 Skipped, 1 Total, 2-sec Throughput (Mb/s): 932.9565 
...
/subscriptions/aff271ee-e9be-4441-b9bb-42f5af4cbaeb/resourceGroups/nixos-images/providers/Microsoft.Compute/images/azure-image-todo-makethisbetter

Take the output, boot an Azure VM:

img="/subscriptions/.../..." # use output from last command
./boot-vm.sh "${img}"
...
=> booted

Future Work

1. If the user specifies a hard-coded user, then the agent could be removed. Probably has security benefits; definitely has closure-size benefits. (It's likely the VM will need to be booted with a special flag. See: https://github.com/Azure/azure-cli/issues/12775 for details.)
