Team Foundation Server(Release Pipeline) - powershell

I'm developing Release pipeline for deploying artefacts using TFS 2017 Update3 Release Management. There are various tasks like "Windows Machine File Copy" and "Run Power Shell on Target machines" which needs admin credentials to be passed as input parameters. These admin credentials have Administrative access on target nodes. I'm using Windows service accounts for these. We have an organisational security policy to rotate passwords every month.
With that in mind, it is hectic to update hundreds of TFS release definitions for new password every month.
Do you have a better idea to handle this? Please give detailed answers.
Thanks in advance.

You could use a variable group to store values that you want to make available across multiple build and release definitions. Variable groups are defined and managed in the Library tab of the Build & Release hub. In this way, you can just edit the variable group:
https://learn.microsoft.com/en-us/vsts/pipelines/library/variable-groups?view=vsts

If you want to automate the process you use the solution defined here. This details how to use the TFS API to poke the definitions.
Alternatively you could create your own PowerShell task that sources the password from some alternative source like Azure Key vault or even hard code it into the json task definition itself (don't do this).
You can vote to improve this story here.
I wrote a custom version of the PowerShell task that uses the identity of the agent as part of the WinRM session which greatly simplifies our release definition process.

How to integrate powerapps with azure devops

I am doing some research for Powerapps integration with Azure DevOps.
However there is limitated information for it.
It is possible to integrate powerapps inside a Task for AzureDevops?
Based on, that we have a .zip file with the Powerapp, and we want to create a Build and Release/Deploy for several environments.
Thank You.
It is possible to integrate powerapps inside a Task for AzureDevops?
Yes it is.
You can leverage the Solution concept of the Microsoft Power Platform and the Power Apps BuildTools (preview) extension for Azure DevOps.
Update 11/2020: This is now GA and called Power Platform Build Tools
I've written a complete step-by-step guide on this topic:
A Continuous Delivery Approach for No-Code Solutions in Microsoft’s Power Platform
Bottom line:
With this build tool, you can automatically check-in a Solution into source control and deploy it using a continuous delivery approach with the help of Azure DevOps. See the screenshot for a sample configuration of the Export and Import Solution Task.
It works for everything you can organize inside a Solution, e.g.:
Power Apps
Power Automate Flows
AI Builder Models
Common Data Service Entities
It is possible to integrate powerapps inside a Task for AzureDevops?
I am afraid there is no such Task integrate powerapps for AzureDevops at this moment.
If you want to integrate powerapps with azure devops, you can follow the guide step by step:
Microsoft Teams – Integration with Visual Studio Team Services using PowerApps.
Besides, AFAIK, PowerApps should not be "Build/Deployed" through Azure Devops.
When you are developing with PowerApps, there is no way to do Source
Control. There are no source files. The only artifact you can version
control is the .zip file that you can export.
And
In PowerApps, you don’t have to build your code. Any change you make
to the application is live for you to test it. In that way it is very
productive. To publish the application you just click on the publish
button and it is live.
Check this great blog: PowerApps From A DevOps Perspective for some more details.
Hope this helps.
Solutions are a way to package your components in a single zip file and use Powerapps build tools to import your solution on to a different environment or tenant.
It is still a an improvement from manually importing each app or environment variable and then import it on to target system, but it lacks what we call as automation of deployment.
To provide an eg, I will explain what I have done, and what still constitutes of a manual task:
I created an enterprise level app using powerapp canvas model. My app consumes data from around 20 APIs. These API calls are implemented in power automate.
We have 4 environments, dev, sit, uat and prod. Now I cant keep on importing flows in each environment and change their api URLs to point to the deployed environment. So I used environment variables for each environment which stores api URLs for each environment. This can be done under solution.
Under the same solution, I added my app. So now my solution has 2 things, my app and the environment variable which consists of api URLs.
I then use powerapps build tools to move this solution from dev to sit.
Steps: use build tools tasks to perform the following
Export solution
Unpack it in git
Pack it
Import the solution.
This successfully moves my solution to sit.
But the solution environment variable still points to the dev url.
So I have to override environment variables to store sit URLs.
This manual intervention to edit environment variable is as good as doing all the tasks manually.
This was the case when PowerApps was first announced; however, this is no longer the case.
While it is technically true that there is no actual code that would be managed and deployed with a PowerApp or Flow but that doesn't mean that you can not use the power of Azure DevOps. Additionally, when creating a PowerApp / flow you would also be creating entities and even Model Driven apps - and these uses solutions - which naturally work well to deplooy within Azure DevOps.
Microsoft is building out this whole construct to enable all these to deploy...
While the whole incorporation of PowerApps and flows into Solutions is not fully baked yet - they are targeting to have this ready around the October time frame this year.
We have been talking to Microsoft about also enabling PowerApps and flows to follow the same expansion that solutions do so that they can take advantage of the full branching strategy.
So even though you would be simply exporting out zip files into your repo - you can still take advantage of the full devops pipeline which is highly recommended.
Use this component, it still on preview mode but is working fine on my side

TFS 2018 set security for environment in release definition via script

I need to create a script that sets security to a given environment in a given release definition (as input I have TFS url, project ID, release ID and environment ID).
With the script, I need to set all the environment specific permissions:
Administer release permissions
Delete release environment
Edit release environment
Manage deployments
Manage release approvers
I did not find any method for this in the API.
I also tried to sniff the network traffic as suggested in this question. But for this task it looks too difficult. The request body is full of some identifiers (I do not know where how to get them).
The question is: how can I set environment specific permissions via script?
(preferably with PowerShell Invoke-RestMethod)
I think the only way at the moment is to use tfssecurity.exe!
Here is a good guide and also a download of an Excel that helps you to create your tfssecurity statements. You can find tfssecurity.exe in your TFS-Folder.

Best practice for scripting Azure resource creation

I'm creating a test environment in Azure. I want to have an accurate script of what of the configuration so it's easy to replicate for other test, pre-prod and prod environments later on. The environment has an existing subscription, and I want the entire hierarchy of resources from Resource Groups through to Web Apps to be created by script.
I'm currently rolling my own script in PowerShell utilising AzureRm. This is working well, but I can't help feel I'm reinventing the wheel. What is the existing method for creating an entire Azure environment by script?
Yes, that way is called Azure Resource Manager Templates. Quote:
With Resource Manager, you can create a template (in JSON format) that defines the infrastructure and configuration of your Azure solution. By using a template, you can repeatedly deploy your solution throughout its lifecycle and have confidence your resources are deployed in a consistent state. When you create a solution from the portal, the solution automatically includes a deployment template. You do not have to create your template from scratch because you can start with the template for your solution and customize it to meet your specific needs. You can retrieve a template for an existing resource group by either exporting the current state of the resource group, or viewing the template used for a particular deployment. Viewing the exported template is a helpful way to learn about the template syntax.
Reference: https://learn.microsoft.com/en-us/azure/azure-resource-manager/resource-group-overview#template-deployment
Edit: you can use powershell, azure cli, azure cli2, azure sdk to deploy those templates (or simply Azure portal, search for "Template Deployment")

Using VSTS Release Management, how can I modify the configuration of an Azure Web App for each environment?

I'm using Visual Studio Team Services and I'm trying to set up Release Management to allow automated deployments for our Azure Web App to multiple environments. I would like the same source to be deployed to each environment, but with modified configuration settings.
I was hoping that I could create a single Build for my application, and then modify the configuration at deployment time for each environment. I'm aware that this can be done for appSettings and connectionStrings (either through Tokenization, or even managing those settings via the Azure portal), but I'd like to be able to make more general changes to the web.config file. For example, I want to be able to:
Update 'simple' settings such as appSettings/connectionStrings
Update multiple attributes on elements (like httpErrors)
Insert or rewrite sections of the config file itself (for example to add IIS rewrite rules, or to remove unwanted HTTP handlers for production)
Currently we achieve this by using config file transformations and separate publish profiles for each environment (manual deployment). I can't see a way to re-use this if I want a single release pipeline.
I'm hoping someone can help point me in the right direction. I'm also happy to accept alternative solutions - ultimately I just want to be able to deploy the same source (e.g. from the same commit in source control) to multiple environments, with different configuration, while keeping some kind of flow from dev, to test, to eventually production.
You can use Tokenization Task to update the files base on the environment variables.

Environment specific EF6 Code First Migrations using VSTS Release

I have a project that uses Entity Framework 6.x, ASP .NET WebApi 5.x. Data Access is in a secondary project inside the solution. I want to use VSTS (aka Visual Studio Online) to build and release it as a website to environments for integration/dev, qa, stage, and production. There are some great videos on Channel 9 that deal with the generic high-level description. (for example https://channel9.msdn.com/Series/DevOps-Release-Management and https://channel9.msdn.com/Series/DevOps-Fundamentals/Infrastructure-as-Code) There are all kinds of articles and videos about how to do migrations from inside Visual Studio including generating scripts.
Searching around the web I don't even find any older resources or concrete examples of continuous deployment with code first migrations. There must be examples and best practices for methods other than auto-migrations or SQL scripts.
I have configured a Web Deployment Package publish profile. I use it via the PublishProfile msbuild.exe directive. The package is added to the artifacts and then deployed by the Azure Web App Deployment task in each Release environment. However once this package is built, I don't know of a way of changing the connection string in the build package for each time it is released to an environment.
There is probably something I am overlooking, but how should environment specific migrations be done with via VSTS Release?
For Code First Migration, you can "Write App_Start code to run Migrations" or "Write Web.config transforms to configure the MigrateDatabaseToLatestVersion initializer to run", refer to this article for details: http://blogs.msdn.com/b/webdev/archive/2014/04/09/ef-code-first-migrations-deployment-to-an-azure-cloud-service.aspx
For the connection string transformation with profile, you need to add a web.config file for the publish profile and then enter the connection string in this web.config. Refer to this link for details: http://awaitwisdom.com/publish-profile-config-transform/
I hate to answer my own questions here but, ultimately my research took me to the conclusion I am posting at length here. In sort, Web.config and Parameters.xml require some custom scripting that will require you to maintain your own deployment automation. These routes will still require you to additionally create your resource groups or manage them manually.
To avoid these complications and cobbling tools and scripts together, the whole operation can be achieved with two JSON files. These JSON deployment templates allow you to create or update your resource group when your deployment runs. They also allow you to automate setting appsettings and connectionstrings that overwrite your Web.config values in the same manner as you can through the Azure Portal.
the steps: (1) Add the two JSON files to the project setting the name of you connection string on line 88 (2) Add a Azure Resource Group Deployment task to the Release environment. (3) Set Template (WebSite.json) and Template Parameters (WebSite.parameters.json) paths in the task. (4) Set Override Template parameters to -hostingPlanName "myHostingPlan" -webSiteName "myWebsiteName" -connectionString "the-actual-connection-string" (5) make sure you are using the same website name in your Azure App Deployment task.
This does depend on having your code first migrations run via App_Start or something similar. I took the first part of #Eddie's suggestion since App_Start is easy to deal with and doesn't seem to run too often.
As a bonus you can add environment variables for any of this configuration so you can clone the environment and then just change the variables. This ultimately makes your application or api connection string a Release variable.
