Docker run nanoserver not starting

I am trying to run the nanoserver image on a windows server 2016 (ec2 instance, or Azure VM) with this command:

docker run -d --name nanoms microsoft/nanoserver:latest

edit: actually it is not just nanoserver, I get the same problem running microsoft/windowsservercore:latest.

But if I then run (docker ps -a) it then shows the status as Exited. Docker logs nanoms - only shows "c:>" (so no errors)

If I use -it instead of -d then it shows some 'stuff' and hangs until I hit ctrl-C, but it has actually started and I can 'login'!

'stuff' shown:

edit 2: The above 'stuff' happens when I run the command in powershell. If I run the command in cmd prompt then using -it does successfully connect. BUT -d still always exits.

Is there something I am doing wrong here? Is there something special with windows server 2016 and docker that means -d does not work? Starting a container with -d is kinda fundamental I would think...

I have tried restarting the server, same result.

The nanoserver is a 10.0.14393.693 based image (.823 had some problem).

=================

To recreate the issue:

  1. Spin up either an EC2 instance or an Azure VM, OS == Windows Server 2016 - with Containers.
  2. RDP in, fire up a CMD window (or Powershell)
  3. Run the command: docker run -d microsoft/nanoserver
  4. Once that completes run the command: docker ps -a
  5. Verify, is the container active or exited?

My expectation is that is should be Active. Is my expectation wrong?

Solution

  • yes, your expectation is wrong :)

    The container needs to be running something. For example the command prompt you create when you ran with -it parameters. Explicitly specifying popwershell will probably work better for you...

    docker run --name nanoms microsoft/nanoserver:latest -it powershell
