Photon OS is an open source, minimal Linux container host that is optimized for cloud-native applications. On Azure, it ships with just over a hundred packages including systemd, cloud-init and docker but Photon offers over a thousand packages in their repos like Go, .NET Core, Postgres, Tomcat, Zookeeper or Kubernetes!
This is a simplified version of the Azure quickstart experience in the official Photon OS documentation. It was tested with Photon OS 3.0 GA and azure-cli version 2.0.38.
Prerequisites
- Download the VHD for Azure from GitHub and extract with
tar xfin your local system - Ensure you have the latest Azure CLI (
az) available in your working system and that you've logged in withaz login
Getting started
Just like any other custom Linux VHD, you'll create a few workspaces, upload the VHD and create a new VM based on it.
Here's a script that simplifies the VM creation. It assumes that an SSH keypair is available in the profile of whatever user runs this script. It expects the downloaded and extracted VHD as an argument, for example: ./script.sh photon-azure-3.0-26156e2.vhd:
$ ./script.sh ./photon-azure-3.0-26156e2.vhd
+ set -e
+ GROUP=photon-rg
+ STORAGE=phrg999
+ LOCATION=southcentralus
+ VM_NAME=photon-vm
+ STORAGE_CONTAINER=vhds
+ IMAGE_PATH=./photon-azure-3.0-26156e2.vhd
+ basename ./photon-azure-3.0-26156e2.vhd
+ IMAGE_NAME=photon-azure-3.0-26156e2.vhd
+ az group create -n photon-rg -l southcentralus
+ az storage account create -n phrg999 -g photon-rg
...
+ az vm create -n photon-vm -g photon-rg --os-type linux --image https://phrg999.blob.core.windows.net/vhds/photon-azure-3.0-26156e2.vhd --use-unmanaged-disk --storage-account phrg999
{
...
"powerState": "VM running",
...
The az vm create command will output (in JSON, by default) information about the newly created VM, including a public IP address you can use to SSH into the VM. If you missed it, run az vm list-ip-addresses -o table.

Cleaning up
If you used a unique resource group name in the $GROUP variable above, you can remove all resources by running az group delete -g <group name> --yes. This will remove all resources created by the script, including the uploaded blob, but won't delete it from your local working folder.
Have fun!
