How to deploy my app to Web App?

Question

How to deploy my app to Web App?

Keith Viking 20

I have created a test .Net 6 app (open Visual Studio and create a standard web app and ran it). Next in Azure DevOps i set up my repository and alll looks the way i would expect it to. I would now like to deploy this app to a Azure Web App which should provide me with a public test Url (or i can create one if thats the process) but the end goal is to display this test app in a browser. A new pipeline has been created to ensure the application builds first before deploying. I can see this listed under Pipelines. I read i need to setup a Environment (Environments, create new) but when i do this it asks for me to select a resource (Kubernetes or Virtual Machine). I dont want to use these. From what i have read i need some YAML file to process this but the instructions on this are very vague. How could i set up an Environment so i can deploy this app to a Windows Server running as/on a Web App which would be part of the entire pipeline so when someone pushes in new changes it would build > successful build would then deploy the app which can then be viewed in a web browser (for now a temporary URL would be ok)?

Hey @Keith Viking

I think you came across documentation that wasn't mean for your use case. Have a look Configure CI/CD with Azure Pipelines - Azure App Service | Microsoft Learn. It walks you step by step how to create your build and deployment pipelines. Really all you need is to configure a service connection, which DevOps will walk you through, and configure you pipeline:

variables:
  buildConfiguration: 'Release'

steps:
- script: dotnet build --configuration $(buildConfiguration)
  displayName: 'dotnet build $(buildConfiguration)'
- task: DotNetCoreCLI@2
  inputs:
    command: 'publish'
    publishWebProjects: true
- task: AzureWebApp@1
  inputs:
    azureSubscription: '<service-connection-name>'
    appType: 'webAppLinux'
    appName: '<app-name>'
    package: '$(System.DefaultWorkingDirectory)/**/*.zip'

For build configuration, you set this trigger of the pipeline or remove it for now so that you can get up and running.

Hi

I tried the above but it doesnt seem to work as i expect it.

Background Info

I have an Azure Web App and under the Deployment Center i connected the primary branch to my Azure DevOps project.

I click the domain link similar to test.azurewensites.net and i see a page appearing with the message

Your web app is running and waiting for your content

Here are the steps i took following the link.

I click Pipelines and created a new pipeline (i left the existing one the way it is). I selected my Asp Net Core application and once the YAML was present i then selected Azure Web App on the right and Authorized it. Save and run.

At this point i got a few emails stating the pull request succeeded/token added and then one failed message which contains the below messages.

Its at this point where i am lost. I dont know why its not publishing the test application to the test site (test.azurewensites.net - not correct URL) so i just keep seeing the standard message?

|/azure-pipelines-testing-dep.yml (Line: 2, Col: 1):
A sequence was not expected| | -------- | |/azure-pipelines-testing-dep.yml (Line: 2, Col: 1): A sequence was not expected| |/azure-pipelines-testing-dep.yml (Line: 13, Col: 1): While parsing a block collection, did not find expected '-' indicator.|

@Keith Viking can you share you yaml pipeline?

I deleted the existing ones thinking i may have done something wrong so i have a new error about a zip file but i dont know why its expecting it or if i missed a step or even deleted a pipeline that was once working. Error Error: No package found with specified pattern: D:\a\1\s***.zip<br/>Check if the package mentioned in the task is published as an artifact in the build or a previous stage and downloaded in the current job.

@Keith Viking, I think the issue you're having is your default working directory is empty. In your pipeline, you should be able to check the $(System.DefaultWorkingDirectory) for your zip file. If it's empty, then you know your VSBuild@1 task is publishing the artifacts to the wrong folder. I suggest using the same environment variables between your build and publish task. You can also check the app service deployment logs to see what was actually extracted.
