Best workflow to restart app service after a git push - azure-web-app-service

Short version: How can I deploy a new version without first manually stopping the app-service?
Long version:
I'm using the following workflow to publish a new version of my ASP.NET Core app to an Azure App-Service.
The App-Service is running on a basic instance. I understand this is not intended for real use but I hope there is a good way to get this workflow running before we go into production(standard instance).
This works but how can I avoid step 4 to 7?
Publish the solution into a local folder.
Move the published content into a local git repo.
Commit all files and push to the app-service.
Stop the app-service from the portal
Enter the console and delete all files in the wwwroot folder
Redeploy the commit from the portal
Start the app-service
I was hoping that the push in step 3 would automatically trigger the remaining steps.
After step 3 I can see that the files have been updated, the new static files are served to the browser but the old binary is still running.
Similarly I can switch between deployment slots on the portal. I get the new static files served but the previous deployed binary is still answering all calls.
This doesn't work, the static files are changed but the old binary is still responding to calls.
Redeploy from portal
Restart app-service
The old binary is still served.
This works.
Stop app-service
Deploy from portal
Start app-service
It appears the running binary is blocking the deployment.
How can I automate deployment using git push or from the portal without manually having to stop the service?
Application settings:

You need to enable msdeploy flag MSDEPLOY_RENAME_LOCKED_FILES=1 in Azure App Service application settings. The option if set enables msdeploy to rename locked files that are locked during app deployment
Click application settings and scroll down until you see app settings.
set this key: MSDEPLOY_RENAME_LOCKED_FILES and for its value put 1

How can I deploy a new version without first manually stopping the app-service?
When I develop my .Net Core Web application via VS, I would leverage the publish wizard, check the option Remove additional files at destination and use the App offline support by setting EnableMSDeployAppOffline to true under the publish profile for publishing my application to Azure Web App.
Based on your current deployment workflow, I assume that you are using the Continuous Deployment to your Azure App Service with your local Git Repository. After I changed the source code, then commit the changes to the local repository, then push the source code to my web app remote repository, the source code would be built and copied to D:\home\site\wwwroot on Azure side. Details you could follow Local Git Deployment to Azure App Service.
For your step 1 to 3, I just push the code changes from the local repository to my app service remote repository. Azure would generate the deployment script for you to build your source code project and move the built content to D:\home\site\wwwroot. Moreover, you could Custom Deployment Script for your additional requirement.

How to deploy a desktop application to a physical server using Azure Pipelines?

what I did;
I have my c# windows form application on Azure Repo and I created a build.
I assigned my physical test server to Azure DevOps under the Deployment groups page. And it is online.
I defined a release, I added an artifact that refers to the build pipeline from the Azure repo.
Now I want to transfer my windows form app release files to my physical test server (windows) under the Desktop folder and run. (also stop and delete previous app if it is already running)
For that, I tried to add a stage. But for the stage templates, I don't know which one to choose. There are deployment options for IIS and Azure services.
Bufre, I published my ASP.NET app using IIS website deployment. Worked fine. But how to do it for a desktop application? How to transfer and run?
I see a as a similar issue here, But I am new to YAML files and I could not produce.
Where to mention target physical path, which template to choose? Could you please advise on the steps?
You must install the DevOps agent on this server, then add it to the agent pool and then use any task that allows to install your app (depends on what kind of app you have). All tasks will be executed on the server directly, so you can use PowerShell, cmd or what ever.

How can I clean out an older deployment on my App Service in Azure?

I have a new version of my web app and after a new deployment from a new Bitbucket repo the old version is still served. I've deleted the App Service and then created it again, but still the old stuff is served. Everything I've tried results in a successful deployment of the new code, but when I browse the site, the old version is served. To get rid of the old code can I go to the console and just delete everything in site/wwwroot? Is there a git repo in Azure I can initialize?
According to your description, I assumed that you are using continuous deployment for your Azure App Service app. AFAIK, for basic web site deployment, azure would clone your Bitbucket repo to D:\home\site\repository, then restore packages or compile your project, then deploy your project to D:\home\site\wwwroot.
As David commented that you could leverage KUDU or ftp tool (e.g. FileZilla) to check your files under site\wwwroot and site\repository, and compare with your Bitbucket repo to make sure your source code has been synced into site\repository.
Also, you could try to delete site\wwwroot and site\repository via KUDU, then Disconnect and set your continuous deployment again on Azure portal to isolate this issue.

How to deploy to azure app service from VSTS?

I have nodejs app. Can I deploy it to azure app service without VS or other big IDE?
So, I want an easy way to select branch what I need push it to azure and run default command for nodejs.
I'm stuck with it, because all of solution it is use VS.
You can deploy to azure app service by using Azure App Service Deployment step/task. For example:
Create a build definition
Add related step/task to build your project
Add Azure App Service Deployment step/task (Can publish using Web Deploy or upload files directly)
Select Triggers tab and enable Continuous Integration
Specify repository and branch filters
After that, the build will be triggered if you push changes to target branch.
Related article: Define a continuous integration build for your Node.js app
Regarding run command for nodejs, you can refer to this thread by using kudu API: Include node modules in azure deployment via VSTS.
This can be done. Take a look at the build and release functionality in Visual Studio Team Services.
With VSTS Build, you can trigger a build and push to an Azure Web App automatically on a Git check-in for a particular branch, or you can manually trigger the build and push.
Take a look at the Azure App Service Deploy task in VSTS build.
Note that since VSTS is pulling from your Git repo, it doesn't matter what IDE you use to actually develop your app with.
Also, VSTS is free for small teams and a single deployment pipeline.

FTP'ing a Suave app to Azure

Having never used Azure before I'm attempting to deploy a simple F# Suave app to Azure using FTP. Ultimately I want to deploy via github but I initially thought FTP'ing it would be the easy first step. According to https://suave.io/azure-app-service.html it should be straight forward.
These are the steps I followed
Created a new web app in Azure including a resource group
and app service plan. All on the Free Tier.
Downloaded the publishsettings XML file that Azure created.
Cloned this repo: https://github.com/isaacabraham/fsharp-demonstrator
Used FileZilla to connect via FTP using the creds
from step 2.
Uploaded the files (via FTP) from
fsharp-demonstrator/src/SuaveHost (which includes the necessary web.config file) from the repo cloned at step 3 to
the site\wwwroot on Azure.
Navigated to Azure site url.
Then I receive the error:
The specified CGI application encountered an error and the server terminated the process.
(When I look at the folders on Azure under site\wwwroot I don't see any obj or bin folders. I don't think any msbuild process occurred. That doesn't seem right.)
Anybody got any idea what the problem is?
I suspect the issue is that when you deploy via FTP, then Azure does not automatically run the deploy script specified in the .deployment file.
The build.fsx script uses Kudu service to deploy the built files, so it might be easier to just use Github deployment rather than FTP - this way, Azure will do the deployment for you.
If you want to deploy via FTP, you'll need to build the project locally and upload the output. I'm not sure how to best do this with Isaac's Kudu-based demo though (ultimately, you need web.config that points to your built executable like this)

Automatically upload local changes into windows azure / amazon s3 cloud server

I have to create a Visual Studio project with the following functionality,
Once the project is created, the service should automatically upload the project files in to cloud storage (using windows azure or amazon s3 server).
If any changes in the project files, instead of uploading the whole project, only the modified files has to be uploaded. ( like SVN commit).
Could anyone please let me know if you have any ideas on this?
What you describe is more-or-less what "git deployment" is about - deploying changes to a web site or application by pushing the changes from a local git repository to a remote one. The deployment triggers a service or script on the remote repository that updates your site.
Azure supports this for Azure Web Sites. See for example Continuous deployment using GIT in Azure App Service for a step-by-step guid on how to create a new site, deploy and update it using Git.
The engine that automates git deployments in Azure is available as an open source project, Project Kudu which can be hosted outside Azure, eg on your own web server.
Amazon doesn't offer all of this out of the box. Its Elastic Beanstalk offering allows you to publish an ASP.NET MVC project to a specific configuration (VMs, settings etc) right from Visual Studio but it's a manual process and doesn't deploy only changes. Check How to Deploy an Application Using Elastic Beanstalk for a step-by-step guide.
You can use Project Kudu on an Amazon VM to use git deployment. This won't set up the VMs as Beanstalk does, but it will deploy only the changes to your site.
