I am running Docker Desktop version 2.1.0.4 (engine 19.03.4) on Windows 10 1903.
Windows container mode
Experimental On
I am trying to copy files into a Windows container.
Steps to reproduce the issue:
1 - The Docker Run is ok using mcr.microsoft.com/windows/servercore/iis:windowsservercore-ltsc2016
2 - Docker PS display my container
3 - I can browse a website hosted on my container.
4 - I docker stop the container
5 - docker cp fails with No such container.
6 - in the Docker events:
– container kill
– container die
– network disconnect
– container stop
– container destroy
Why the container is automatically destroyed after stop? I found nothing in the documentation explaining this.
Have you an idea?
PS: as long as the container is not stopped, it successfully works.
You probably know containers are not “persistent” and if you want to run a website, for example, you should create/mount persistent directories for both apache and mysql, let’s say.
The extend of my knowledge ends with https://docs.docker.com/storage/volumes/ , and I’ve just google that there is no “checkpoint” support on Windows, which would be the other semi-preferred to “pause” a container . But you may be right, that auto-destroy is a bit suspicious
It seems to be by design for the Windows containers only. On the same machine, same Docker Desktop version a linux container is not destroyed after stop.
This is a real problem in fact because when Windows got updates, the container is destroyed and when Docker get update the container is also destroyed.
