Running Vsts agent on nano server

I am looking to run vsts agent on docker image with nano server on it. The container already has .Net Core installed on it. I downloaded vsts agent using the Download Agent and config.cmd command. Got the following error

An error occurred while sending the request. Failed to connect.  Try again or ctrl-c to quit

Here are the details

Windows Version: Microsoft Windows [Version 10.0.14393]

.Net Core Version : 1.0.1
.Net Core Build : cee57bf6c981237d80aa1631cfe83cb9ba329f12

Looking at Diagnostics log, I get the following error

Can anyone help please?

Solution

  • I had it raised as an issue with the product team. https://github.com/Microsoft/vsts-agent/issues/483

    The scenario is not supported as yet. I.e VSTS agents can't run Windows Nano Server. Following are excerpt from the response the team

    "It's likely not just this issue. The Windows build of the agent currently makes an assumption that Full .NET is installed. It has validation checks that verify that .NET >= 4.5 is installed. It sounds like it's missing validation to distinguish between .NET Full and .NET Core.

    My understanding is that Nano doesn't have .NET Full, and only has .NET Core. We'll need to take a pass through the agent, given Nano constraints, and figure out what it means for an agent running on Nano."
