Every Tool's a Hammer: Life Is What You Make It
 

(Adam Savage) 

- I really liked this book. In fact, As I was reading the first chapter I was "earing" Adam's voice. So instead of creating that voice in my head I bought the audiobook and let Adam himself tells me his story. This is the best book I listen to this year. It was inspiring and empowering.

Simplify your deployment with nested Azure Resource Manager (ARM) templates


Most solutions, if not all, are composed of multiple parts: backend, frontend, services, APIs, etc. Because all parts could have a different life-cycle it's important to be able to deploy them individually. However, sometimes we would like to deploy everything at once. It's exactly the scenario I had in a project I'm working on where with backend and one frontend.

In this post, I will explain how I use nested Azure Resource Manager (ARM) templates and conditions to let the user decide if he wants to deploy only the backend or the backend with a frontend of his choice. All the code will be available in GitHub and if you prefer, a video version is available below.
(This post is also available in French)

The Context


The project used in this post my open-source budget-friendly Azure URL Shortener. Like mentioned previously the project is composed of two parts. The backend leverage Microsoft serverless Azure Functions, it a perfect match in this case because it will only run when someone clicks a link. The second part is a frontend, and it's totally optional. Because the Azure Functions are HTTP triggers they act as an API, therefore, they can be called from anything able to do an HTTP call. Both are very easily deployable using an ARM template by a PowerShell or CLI command or by a one-click button directly from GitHub.

The Goal


At the end of this post, we will be able from one-click to deploy just the Azure Functions or to deploy them with a frontend of our choice (I only have one right now, but more will come). To do this, we will modify the "backend" ARM template using condition and nest the ARM template responsible for the frontend deployment.

The ARM templates are available here in there [initial](https://github.com/FBoucher/AzUrlShortener/tree/master/tutorials/optional-arm/before) and [final](https://github.com/FBoucher/AzUrlShortener/tree/master/tutorials/optional-arm/before/after) versions.

Adding New Inputs


We will nest the ARM templates, this means that our backend template (azureDeploy.json) will call the frontend template (adminBlazorWebsite-deployAzure.json). Therefore we need to add all the required information to azureDeploy.json to make sure it's able to deploy adminBlazorWebsite-deployAzure.json successfully. Looking at the parameter required for the second template, we only two need values AdminEMail and AdminPassword. All the other can be generated or we already have them.

We will need also another parameter the will act as our selection option. So let's add a parameter named frontend and allowed only two values: none and adminBlazorWebsite. If the value is none we only deploy the Azure Function. When the value is adminBlazorWebsite we will deploy the Azure Function, of course, but we will also deploy an admin website to go with it.

Following the best practices, we add clear detail and add those three parameters in the parameters section of the ARM template

"frontend": {
    "type": "string",
    "allowedValues": [
        "none",
        "adminBlazorWebsite"
    ],
    "defaultValue": "adminBlazorWebsite",
    "metadata": {
        "description": "Select the frontend that will be deploy. Select 'none', if you don't want any. Frontend available: adminBlazorWebsite, none. "
    }
},
"frontend-AdminEMail": {
    "type": "string",
    "defaultValue": "",
    "metadata": {
        "description": "(Required only if frontend = adminBlazorWebsite) The EMail use to connect into the admin Blazor Website."
    }
},
"frontend-AdminPassword": {
    "type": "securestring",
    "defaultValue": "",
    "metadata": {
        "description": "(Required only if frontend = adminBlazorWebsite) Password use to connect into the admin Blazor Website."
    }
}

Nested Templates


Let's assume for now that we always deploy the website when we deploy the Azure Function, to keep things simple. What we need now is to used nested ARM template, and that when you deploy an ARM template from inside another ARM template. This is done with a Microsoft.Resources/deployments node. Let's look at the code:

{
    "name": "FrontendDeployment",
    "type": "Microsoft.Resources/deployments",
    "dependsOn": [
        "[resourceId('Microsoft.Web/sites/', variables('funcAppName'))]",
        "[resourceId('Microsoft.Web/sites/sourcecontrols', variables('funcAppName'), 'web')]"
    ],
    "resourceGroup": "[resourceGroup().name]",
    "apiVersion": "2019-10-01",
    "properties": {
        "mode": "Incremental",
        "templateLink": {
            "uri": "[variables('frontendInfo')[parameters('frontend')].armTemplateUrl]"
        },
        "parameters": {
            "basename": {
                "value" : "[concat('adm', parameters('baseName'))]"
            },
            "AdminEMail": {
                "value" : "[parameters('frontend-AdminEMail')]"
            },
            "AdminPassword": {
                "value" : "[parameters('frontend-AdminPassword')]"
            },
            "AzureFunctionUrlListUrl": {
                "value" : "[concat('https://', reference(resourceId('Microsoft.Web/sites/', variables('funcAppName')), '2018-02-01').hostNames[0], '/api/UrlList?code=', listkeys(concat(resourceId('Microsoft.Web/sites/', variables('funcAppName')), '/host/default/'),'2016-08-01').functionKeys.default)]"
            },
            "AzureFunctionUrlShortenerUrl": {
                "value" : "[concat('https://', reference(resourceId('Microsoft.Web/sites/', variables('funcAppName')), '2018-02-01').hostNames[0], '/api/UrlShortener?code=', listkeys(concat(resourceId('Microsoft.Web/sites/', variables('funcAppName')), '/host/default/'),'2016-08-01').functionKeys.default)]"
            },
            "GitHubURL": {
                "value" : "[parameters('GitHubURL')]"
            },
            "GitHubBranch": {
                "value" : "[parameters('GitHubBranch')]"
            },
            "ExpireOn": {
                "value" : "[parameters('ExpireOn')]"
            },
            "OwnerName": {
                "value" : "[parameters('OwnerName')]"
            }

        }
    }
}

If we examine this node, we have the classic: name, type, dependsOn, resourceGroup, apiVersion. Here We really want the Azure Functions to be fully deployed so we need the FunctionApp to be created AND the GitHub sync to be complete, this is why there is also a dependency on Microsoft.Web/sites/sourcecontrols.

In properties we will pass the mode as Incremental as it will leave unchanged resources that exist in the resource group but aren't specified in the template.

Learn more about the Azure Resource Manager deployment modes here as they are very powerful.

The second property is templateLink. This is really important as it's the URL to the other ARM template. That URI must not be a local file or a file that is only available on your local network. You must provide a URI value that downloadable as HTTP or HTTPS. In this case, it's a variable that contains the GitHub URL where the template is available.

Finally, we have the parameters, and this is how we pass the values to the second template. Let's skip those where I just pass the parameter value from the caller to the called, and focus on basename, AzureFunctionUrlListUrl, and AzureFunctionUrlShortenerUrl.

For basename I just add a prefix to the parameter basename received, this way the resource names will be different but we can still see the "connection". That's purely optional, you could have added this value in a parameter to azureDeploy.json, I prefer keeping the parameters a minimum as possible as I think it simplifies the deployment for the users.

Finally for AzureFunctionUrlListUrl, and AzureFunctionUrlShortenerUrl I needed to retrieve the URL of the Azure Function with the security token because they are secured. I do that by concatenating different parts.

Component Value
Beginning of the URL 'https://'
Reference the Function App, return the value of hostname reference(resourceId('Microsoft.Web/sites/', variables('funcAppName')), '2018-02-01').hostNames[0]
Specify the Function targeted in this case UrlList. And starting the querystring to pass the code (aka. security token) '/api/UrlList?code='
Using the new listkeys function to retrieve the default Function key. listkeys(concat(resourceId('Microsoft.Web/sites/', variables('funcAppName')), '/host/default/'),'2016-08-01').functionKeys.default

Conditional parts


Now that the second ARM template can be deployed, let's add a condition so it gets, indeed, deploy only when we desire. To do this it's very simple, we need to add a property condition.

{
    "name": "FrontendDeployment",
    "type": "Microsoft.Resources/deployments",
    "condition": "[not(equals(parameters('frontend'), 'none'))]",
    "dependsOn": [
        "[resourceId('Microsoft.Web/sites/', variables('funcAppName'))]",
        "[resourceId('Microsoft.Web/sites/sourcecontrols', variables('funcAppName'), 'web')]"
    ]
}

In this case, is the value of the parameter is different then none, the nested template will be deployed. When a condition end-up being "false", the entire resource will be ignored during the deployment. How simple or complex are your conditions... that's your choice!

Happy deployment. :)

The Art of Thinking Clearly

by Rolf Dobelli

I'm still balanced about this book. It was a good book, even if I found some chapters that were too long. I also got lost by moments. I had the impression that some thoughts or ideas were not developed correctly and more quickly wrapped. In counterpart, some were very well served and clear.

Cleaning your mess in the cloud automatically



We all do it. We create resources in the cloud for a demo, or a presentation and forget about them. Then at the end of the month, we receive a bigger invoice then expected and it's the panic.

This is why I thought about AzSubscriptionCleaner. It's an open-source project that could be deployed in your subscription very easily. The goal is to have it deployed by one click directly from GitHub.

The tool can be deployed in two versions, using Azure Automation, or Azure Functions. Based on a schedule it will execute a query to search all resources with a tag expireOn with the value is older than now(), and delete them.

I wrote two blog posts, paired with a YouTube video that explain how to tools where built.
