从Visual Studio 2015在Azure上发布到Docker时出错

Question

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
docker.io/microsoft/aspnet 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://vmname.southeastasia.cloudapp.azure.com:2376 logs cf32793c88939d664f67c651cbc75c4fb348fdd6fe85ea67322f9b5d049c0e70]
Failed to connect to http://vmname.southeastasia.cloudapp.azure.com/. If your Docker host is an Azure virtual machine, please make sure to set up the endpoint '80' using the Azure portal.

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://vmname.cloudapp.net:2376 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 https://vmname.cloudapp.net:2376/v1.22/containers/json?all=1: dial tcp 23.97.54.64:2376: 
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.

Answer 1

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 .
