Reference

ARM templates can:• Simplify deployment• Simplify roll-back• Provide cross-resource

configuration and update support • Be used as a learning tool to build

to suitAzure templates are: • Source file, checked-in• Specifies resources and

dependencies (VMs, websites, DBs) and connections (configuration, LB sets)

• Configurable parameters for input/output

Enterprises and system integrators• Internal software development teams• Delivering an application

• Corporate IT• Delivering a capability or cloud capacity

Cloud Service Vendors (CSVs)• Support different multi-tenancy approaches• Distinct deployments per customer• Within the CSV’s subscription• “Bring your own subscription” model that uses customer subscriptions

• Scale units within a central multi-tenant system• Support ability to make available via the marketplaceAll deploy known configurations/SKUs/VM sizes

Common use cases for ARM templates

Wide range of Quickstart templates• Indexed on Azure.com• GitHub repo• Community and Microsoft contributedIntegration of IaaS with Azure Services

Getting started with Azure templates

Many examples available @ https://github.com/Azure/azure-quickstart-templates

JSON files—simpler than they lookSchema, content version, parameters, variables, resources, and outputs

Deploying custom JSON files

New-AzureResourceGroupDeployment -DeploymentName "Simple-VM" -ResourceGroupNameRG-TESTGROUP -TemplateFile "C:\GitHub\Templates\101-simple-windows-vm\azuredeploy.json

Multiple types of state• Parameters• Static variables• Dynamic variablesTemplates accept parametersTemplates return variables as output valuesSimple or complex object types are supported

Passing state in and out of templates

• Easier to pass a number of related values with a single variable

• Object.Property approach provides additional context when reading the template

Passing state—complex objects

"networkSettings": { "vnetName": "[parameters('virtualNetworkName')]", "addressPrefix": "10.0.0.0/16", "subnets": { "dmz": { "name": "dmz", "prefix": "10.0.0.0/24", "vnet": "[parameters('virtualNetworkName')]" }, "data": { "name": "data", "prefix": "10.0.1.0/24", "vnet": "[parameters('virtualNetworkName')]" } } }

"osSettings": { "imageReference": { "publisher": "Canonical", "offer": "UbuntuServer", "sku": "14.04.2-LTS", "version": "latest" }

"tshirtSizeSmall": { "vmSize": "Standard_A1", "diskSize": 1023, "vmTemplate": "[concat(variables('templateBaseUrl'), 'database-2disk-resources.json')]", "vmCount": 2, "storage": { "name": "[parameters('storageAccountNamePrefix')]", "count": 1, "pool": "db", "map": [0,0], "jumpbox": 0 } },

"availabilitySetSettings": { "name": "pgsqlAvailabilitySet", "fdCount": 3, "udCount": 5 }

Examples

No control flow logic built into ARM template languageAn approach with parameters, variables, and linked templates• Use provides parameter value that provides context, e.g., tshirtSize

parameter is passed in as a value of ‘small’• Using concat and a pre-defined variable, a new variable value is created

which points to the specific , e.g., ‘tshirtSize-small.json’• Template linking is incorporated into the template and uses this new

value to identify which template to deploy.• Common examples are “tshirt sizes” and optional features for a

deployment, e.g., “enableJumpbox”

Control flow

Tools to help manage templatesGitHubVisual Studio CodeNotePad/NotePad++

GIT• A widely used version control system for

software development• A distributed revision control system with

an emphasis on speed, data integrity, and support for distributed, non-linear workflows

• A full-fledged repository with complete history and full version-tracking capabilities, independent of network access or a central server

Visual Studio Code integration with GIT1. Open your team repository in Visual

Studio2. Clone your repository3. Create a new app4. Confirm your settings and add the app5. Snapshot (commit) your code6. Pull changes from your team7. Push your local commits to the server
