Great news for App Service on Linux users that our KUDU new UI provides [instance selector] feature! 

 

Unlike Windows App Service, it used to be difficult for App Service on Linux users to make an SSH connection to the intended instance. You might need to handle Session affinity cookie (ARR cookie) or clean up cookies to allow KUDU to randomly choose an instance to attach.

On new UI, you can choose the instance as easy as the App Service on Windows!

    Is there any reason why this is still in preview after over 3 years, when it provides a much more valuable experience? It should be the default!

    Hey Winnie_Chen , thanks for this blog.

    I am trying to use the Kudu Debug Console for a Linux App Service.

    ( I would like to check connections using bash or powershell there).

    I am able to do this for a Windows App Service.)

     

    For Linux App, I am just seeing the following for the original UI(at myapp.scm.azurewebsites.net),

    not seeing the Environment SSH Bash etc tabs as shown in your original UI.

    Environment

    Build
    1.0.0.7 (<commit>)
    Site up time
    00.03:56:00
    Site folder
    /home
    Temp folder
    /tmp/

    REST API (works best when using a JSON viewer extension)

    • App Settings
    • Deployments

    More information about Kudu can be found on the https://github.com/projectkudu/kudu/wiki.

     

    For the new ui endpoint (myapp.scm.azurewebsites.net/newui), I am getting 404.

     

    Is this some version issue?

     

    Any thoughts?

     

    Thanks!
