Azure ARM Template osprofile dependency - azure

Question

I have problem when creating my custom template. I am trying to create VM from vhd as vhd but in deployment it fail with error osProfile missing. It is interesting because in other template from internet I see there is no osprofile section and it is deploying without problems.
So I added osProfile with computerName parameter. But now deployment failing with error there is adminUsername and adminPassword needed. I don´t understand how is possible that in another script this is not requied and it will create VM without problems.
There is also fact that my template is creating VM using vhd but that other template is creating VM using managed disk. Is this possibly problematic?
My piece of code:
"apiVersion": "2017-03-30",
"type": "Microsoft.Compute/virtualMachines",
"name": "[parameters('vmName')]",
"location": "[parameters('location')]",
"dependsOn": [
"[concat('Microsoft.Network/networkInterfaces/', variables('nicName'))]"
],
"properties": {
"hardwareProfile": {
"vmSize": "[parameters('vmSize')]"
},
"osProfile": {
"computerName": "[concat(parameters('vmName'))]",
"adminUsername": "",
"adminPassword": ""
},
"storageProfile": {
"osDisk": {
"name": "[concat(parameters('vmName'),'-osDisk')]",
"osType": "[parameters('osType')]",
"caching": "ReadWrite",
"image": {
"uri": "[parameters('osVhdUri')]"
},
"vhd": {
"uri": "[variables('osDiskVhdName')]"
},
"createOption": "FromImage"
}
},
"networkProfile": {
"networkInterfaces": [
{
"id": "[resourceId('Microsoft.Network/networkInterfaces',variables('nicName'))]"
}
]
},
"diagnosticsProfile": {
"bootDiagnostics": {
"enabled": true,
"storageUri": "[concat(reference(concat('Microsoft.Storage/storageAccounts/', parameters('userDiagStorageAccountName')), '2016-01-01').primaryEndpoints.blob)]"
}
}
I know adminUsername and adminPassword can´t be empty but I don´t want this parameters in creating VM from existing vhd.
Piece of template code from deployment successful:
"apiVersion": "2017-03-30",
"type": "Microsoft.Compute/virtualMachines",
"name": "[parameters('vmName')]",
"location": "[parameters('location')]",
"tags": {
"displayName": "VirtualMachine"
},
"dependsOn": [
"[concat('Microsoft.Network/networkInterfaces/', variables('nicName'))]",
"[concat(parameters('vmName'), '_OSdisk')]",
"[concat(parameters('vmName'), '_Datadisk')]"
],
"properties": {
"hardwareProfile": {
"vmSize": "[parameters('vmSize')]"
},
"storageProfile": {
"osDisk": {
"osType": "[parameters('osType')]",
"caching": "ReadWrite",
"createOption": "Attach",
"managedDisk": {
"id": "[resourceId('Microsoft.Compute/disks', concat(parameters('vmName'), '_OSdisk'))]"
}
},
"dataDisks": [
{
"lun": 0,
"managedDisk": {
"id": "[resourceId('Microsoft.Compute/disks', concat(parameters('vmName'), '_Datadisk'))]"
},
"caching": "ReadOnly",
"createOption": "Attach"
}
]
},
"networkProfile": {
"networkInterfaces": [
{
"id": "[resourceId('Microsoft.Network/networkInterfaces',variables('nicName'))]"
}
]
},
"diagnosticsProfile": {
"bootDiagnostics": {
"enabled": true,
"storageUri": "[concat(reference(concat('Microsoft.Storage/storageAccounts/', variables('diagStorageAccountName')), '2016-01-01').primaryEndpoints.blob)]"
}
}
Here is printscreen of failed deployment without osProfile form my template.

Answer 1

change "createOption": "FromImage" to "createOption": "Attach". You are trying to create a VM from marketplace image, not from existing VHD.
in this case you can remove osProfile completely
