Error while publising to docker on Azure from Visual Studio 2015

I’m trying to publish my ASP.NET Core website on Azure Docker through visual studio 2015 using this Visual Studio extension. I have tried different approaches but failed to deploy in each one of them.

Approach 1
Created a windows docker container directly from Visual studio. In this case the VM was created successfully and I was to able validate the connection successfully before publish.

  • However, the publish failed with following error

    Step 1 : FROM microsoft/aspnet:1.0.0-rc1-update1 Pulling repository Error: image
    microsoft/aspnet:1.0.0-rc1-update1 not found

    Approach 2
    Created a Linux docker container directly from Visual studio. Again, the VM was created successfully and I was able validate the connection successfully before publish. On publishing I got following error:

    Executing command [docker --tlsverify -H tcp:// logs cf32793c88939d664f67c651cbc75c4fb348fdd6fe85ea67322f9b5d049c0e70]

    Approach 3
    Created a classic VM from Azure portal with port 80 opened. On validating the connection it failed. While publishing it could not connect to the VM and gave following error:

    Executing command [docker --tlsverify -H tcp:// ps -a | select-string -pattern ":80->" | foreach { Write-Output $_.ToString().split()[0] }]
    C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Web\Microsoft.DNX.Publishing.targets(386,5): 
    Error : An error occurred trying to connect: Get dial tcp 
    connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

    Request your help to figure out the issue in the above three approaches.

    I was able to resolve the issue on my Linux VM. The issue was due to the wrong runtime in dockerfile. The auto-generated dockerfile from Visual Studio tooling had wrong runtime causing the issue.
    The dockerfile had runtime FROM microsoft/aspnet:1.0.0-rc1-update1 changing it to microsoft/aspnet:1.0.0-rc1-update1-coreclr resolved the issue. I got the tip from an answer to similar question raised by me here.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
