Passing additional parameters apart from parameter file in arm template - azure

Question

I have some arm template where creation of subnet resource is dependent on creation of VNet. Below is the code:
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"vnetName": {
"type": "string",
"metadata": {
"description": "Name of the Virtual Network"
}
},
"vnetAddressPrefix": {
"type": "string",
"metadata": {
"description": "The IP Address pool for the virtual network in CIDR format."
}
},
"subnetPrefix": {
"type": "string",
"metadata": {
"description": "The IP Address pool for the Subnet in CIDR format."
}
},
"subnetName": {
"type": "string",
"metadata": {
"description": "Name of the Subnet"
}
}
},
"variables": {
"templateBaseUrl": "[deployment().properties.templateLink.uri]",
"virtualNetworkTemplateUrl": "[uri(variables('templateBaseUrl'), 'VirtualNetwork.json')]",
"subnetTemplateUrl": "[uri(variables('templateBaseUrl'), 'Subnet.json')]",
"parametersUrl": "[uri(variables('templateBaseUrl'), 'networksubnetnsgtest.parameters.json')]"
},
"resources": [
{
"apiVersion": "2017-05-10",
"name": "VnetDeployment",
"type": "Microsoft.Resources/deployments",
"properties": {
"mode": "Incremental",
"templateLink": {
"uri": "[variables('virtualNetworkTemplateUrl')]"
},
"parameters": {
"uri": {
"value": "[variables('parametersUrl')]"
}
}
}
},
{
"apiVersion": "2017-05-10",
"name": "SubnetDeployment",
"type": "Microsoft.Resources/deployments",
"properties": {
"mode": "Incremental",
"templateLink": {
"uri": "[variables('subnetTemplateUrl')]"
},
"parameters": {
"uri": {
"value": "[variables('parametersUrl')]"
}
}
},
"dependsOn": [
"VnetDeployment"
]
}
],
"outputs": {
"returnedVnetName": {
"type": "string",
"value": "[resourceId('Microsoft.Network/virtualNetworks', parameters('vnetName'))]"
},
"returnedVnetAddressPrefix": {
"type": "string",
"value": "[resourceId('Microsoft.Network/virtualNetworks', parameters('vnetAddressPrefix'))]"
}
}
}
Few parameters are saved in parameter file referred by parameterUrl variable, as you can see. But apart from this, i need to pass additional parameters say like password or any required parameter , which i may be reading from external sources like vault, and need to pass from commandline.
How will i pass this in parameters section within resources.
Command i am using to deploy azure template is below:
az group deployment create --resource-group testrg --template-file ${WORKSPACE}/azuredeploy.json --parameters #${WORKSPACE}/networksubnetnsgtest.parameters.json --parameters DBMasterUserPassword=${DBMasterUserPassword}

excerpt from official documentation:
az group deployment create -g MyResourceGroup --template-file azuredeploy.json \
--parameters #params.json --parameters https://mysite/params.json --parameters MyValue=This MyArray=#array.json
