Docker Swarm on Windows with Windows Containers

[3imediamaric]

Hi to all,

**Trying to use Docker Swarm on Windows with Windows Containers **

Steps to reproduce the issue, if relevant:

1. docker swarm init --advertise-addr Local_IP

2. Then we connect our worker PC with command which came from docker swarm init --advertise-addr

3. git clone https://github.com/docker/example-voting-app

4. cd example-voting-app

5. docker stack deploy --compose-file=docker-stack-windows-1809.yml voting_stack

6. After that we get something like this:

7. If we watch one of Services with:

   docker service ps voting_stack_vote

   we get this view:

8. We would appreciate if someone can write to us what we can do to fix our Issue.

Describe the results you received: We are getting Error Messege "No such image: dockersamples/..""

Describe the results you expected: We expected normal installation of required Images and normal connection over localhost:5000 to deployed Site as it is described in dockersamples/example-voting-app GitHub Repository

I can confirm that this image fails a pull on Docker Desktop 19.03.1 (Windows containers) with error:

The other two windows images dockersamples/examplevotingapp_vote:dotnet-nanoserver and dockersamples/examplevotingapp_vote:dotnet-nanoserver-sac2016 pull successfully.

Looks like the 1809 images must be rebuilt and pushed again to Docker Hub. These images are built in October 2018 based on the first release of the nanoserver images, but these base images were rolled back by MSFT. ping @sixeyed

so...I am trying to get this app running on windows. I saw that dotnet was moved to a microsoft archive. I did the transformation as described in https://devblogs.microsoft.com/dotnet/net-core-2-1-container-images-will-be-deleted-from-docker-hub/ and got further but still get the following error: => => exporting layers 0.0s => => writing image sha256:e525ea4b0ec2eb36c645bef763bf002bfeaa457ba4f20c61019ca6b0ae876692 0.0s => => naming to docker.io/dockersamples/examplevotingapp_result:dotnet-nanoserver-1809 0.0s

the windows yml file seems to mention sac2016 version which was not available in the archives at microsoft. So I switched to 1809.

What should I do now?

Hey @michaeladamfons, sorry you're having issues with the build. Due to the complexity of maintaining a dotnet Windows Container version, and lack of Windows Container maintainers in this repo, we're removing that demo from this example and sticking with dotnet for Linux Containers.
