Azure: change an existing Windows Web App to a Linux Web App (docker) - azure

I have an existing Windows Web App in Azure which I want to migrate to a Linux (docker) Web App. It is easy to setup a new Linux Web App with a new URI and that all works. However, I need to preserve the existing URI (myservice.azurewebsites.net) that I have on the Windows Web App and use it in the Linux Web App.
Any downtime is not acceptable, so I cannot just "test" if I can remove the current Windows Web App and "re-use" the same URI.

Created ASP.Net Core Web App and deployed to Azure Windows App Service.
Tried to deploy the same Web App to Linux App Service(Docker), got the below warning.
Tried to continue the steps to provide the configuration access to docker container, got the below error.
For the apps which we want to deploy in Azure Linux Docker, we need to Enable Docker and provide Docker OS , which is not required for Azure Windows App Service.
remove the current Windows Web App and "re-use" the same URI.
It is suggested to create a new App Service Plan and deploy to Linux App (Docker).

How to Deploy Blazor Webassembly Web Application to Azure?

I have created a Blazor Webassembly web application with the PWA feature. It is a CRUD application.
This is my folder structure:
Now I want to deploy it to azure. How can I do that?
The server app is just an ordinary ASP.NET Core application (this is the app that needs to be published). You have several options, like publishing the app to an Azure App Service or an Azure virtual machine. The former would require you to prepare a Docker image (usually a good start would be to enable Docker support for the server project and tweak the created Dockefile to your needs).
Just read the docs at https://learn.microsoft.com/en-us/aspnet/core/tutorials/publish-to-azure-webapp-using-vs?view=aspnetcore-5.0 to get the full picture.

The web server built-in Azure app service

Background:
I am hosting a static web app, generated by NUXTJS on an Azure App Service.
Now I want to configure something more by the web.config like set CORS setting for multiple domains.
But I cannot find any document to figure out what kind of web server has been integrated/installed within the azure app service.
Questions:
Maybe an IIS if the platform is Window based, otherwise Apache when creating AAS in Linux based. Is it correct?
And what is the corresponding version for each?
There are different HTTP server approaches in App Service for Windows and App Service for Linux.
Azure App Service for Windows runs on IIS with the use of modules.
.NET Core apps in App Service on Windows are hosted by ASP.NET Core module
Node.js apps in App Service on Windows are hosted with IISNode.
The IISNode project provides a native IIS 7/8 module that allows hosting of node.js applications in IIS 7/8 and IIS 7/8 Express.
Python 2.7 and Python 3.4 is by default is installed on App Service in root folders on the server
Java apps in App Service on Windows are hosted with Maven plugin
Azure App Service for Linux works a bit differently.

App Service for Linux comes with a bunch of preconfigured containers such as Node, PHP, Java, Python, Ruby and .NET Core.

How do I programmatically create a new instance from hosted containerized web app which running on azure?

I have published and hosted asp .net core web app using azure pipelines. Web app running inside docker container. I want programmatically provision another web app using docker image which was available in azure container registry. The web app should run on a separate url. This url can be configurable. A user will be able to give a name for the web app and can create a web app. I hope to create a separate app for doing this task. Is it possible to do that?

How do I mount an already existing php app to an empty azure php web app

Ok so I created an empty php web app in Azure, and I already have an existing php app that I have only tested locally, question is: How do I "transfer" that app to that empty php web app I created in Azure?
To migrate your existing PHP app to Azure Web Apps, you might need to do the following things:
Deploy all files of your PHP app to a virtual directory's root (D:\home\site\wwwroot) using FTP or source control:
Deploy your app to Azure App Service using FTP/S
Local Git Deployment to Azure App Service
Configure PHP in Azure App Service Web Apps
Azure Web Apps run on Microsoft IIS. If you have ever had your project run on Apache Web server, you also need to translate .htaccess ontent to IIS web.config.

migrating from EC2 to Azure

First of all, I have never used Amazon EC2 neither Windows Azure. But I have a task to move application from EC2 to Azure. App is a REST api written in node.js. Currently I know that there is one EC2 instance with ubuntu with runing app on it. App is deployed to server/instance using tool called Capper. App uses some database and redis. This api is used by mobile clients.
My question is what is the simplest way to move app from EC2 to Azure and what type of service to use on Azure for hosting such app?
You will need to either deploy a Linux-based VM in Azure's "Virtual Machines". Check this article out for assistance: http://www.windowsazure.com/en-us/develop/nodejs/tutorials/getting-started/
Alternatively, you can deploy a node.js app on Windows Azure Websites, by adding a new "Web site" thru the management portal, and pick the node.js template from the gallery of predefined templates.
