This project provides the source code of Linux extensions for Microsoft Azure IaaS
Allow the owner of the Azure VM to run script stored in Azure storage during or after VM provisioning
- it can be installed through Azure RESTFUL API for extension
- it supports major Linux and FreeBSD distro
- the scripts can be located on Azure Storage
- the execution output of the scripts is logged in the log directory specified in HandlerEnvironment.json
- status of the extension is reported back to Azure so that user can see the status on Azure Portal
Python 2.7+
PowerShell script to deploy the extension on VM
$VmName = '<vm_name>'
Write-Host ('Retrieving the VM ' + $VmName + '.....................')
$vm = get-azurevm $VmName
$ExtensionName = '<extension_name>'
$Publisher = '<publisher_name>'
$Version = '<version>'
Write-Host ('Deploying the extension ' + $ExtensionName + ' with Version ' + $Version + ' on ' + $VmName + '.....................')
Set-AzureVMExtension -ExtensionName $ExtensionName -VM $vm -Publisher $Publisher -Version $Version -PrivateConfiguration '{"storageAccountName": "<storage_account_name>","storageAccountKey":"<storage_account_key>"}' -PublicConfiguration '{"fileUris":["<url>"], "commandToExecute": "<command>" }' | Update-AzureVM- To run a script, you need to specify interpreter in "commandToExecute" field, for example:
-PublicConfiguration '{"fileUris":["<url>"], "commandToExecute": "sh myscript.sh"}'-PublicConfiguration '{"fileUris":["<url>"], "commandToExecute": "python myscript.py"}'- If you need to run the same script repeatly, you have to add a timestamp in the "-PublicConfiguration" parameter, for example:
-PublicConfiguration '{"fileUris":["<url>"], "commandToExecute": "<command>", timestamp:1404807859168}'Provide several ways to allow owner of the VM to get the SSH access back
- it can be installed through Azure RESTFUL API for extension
- it supports major Linux and FreeBSD distro
- it can reset the password of the original sudo user
- it can create a new sudo user with the password specified
- it can set the public host key with the key given or it can reset the public host key provided during VM provisioning if host key not provided
- it can open the SSH port(22) and restore the sshd_config if reset_ssh is set to True
- status of the extension is reported back to Azure so that you can see the status on Azure Portal

Set-AzureVMExtension -ExtensionName $ExtensionName -VM $vm -Publisher $Publisher -Version $Version -PrivateConfiguration $PrivateConfig -PublicConfiguration $PublicConfig | Update-AzureVM Allow the owner of the Azure VM to configure the Linux VM patching schedule cycle and the actual patching operation is automated based on the pre-configured schedule.
- it can be installed through Azure RESTFUL API for extension
- it supports major Linux
- it can be configured by the user
- it can patch the os automatically as a scheduled task
- it can patch the os automatically as a one-off
- status of the extension is reported back to Azure so that you can see the status on Azure Portal
