I was able to launch a Linux container as an ephemeral Jenkins agent using SSH. However, I am unable to do the same with a Windows container. I can verify that the SSHD service is running in the Windows container by running it interactively and performing an ssh user>@<container_ip_address.
Only the following log information in the Jenkins Master:
May 28, 2018 2:06:54 PM INFO com.github.kostyasha.yad.DockerCloud provision Will provision 'jenkins/windows-ssh-slave:1.0', for label: 'docker-windows-slave2', in cloud: 'YADP-windows-cloud' May 28, 2018 2:06:54 PM INFO com.github.kostyasha.yad.DockerCloud addProvisionedSlave Provisioning 'jenkins/windows-ssh-slave:1.0' number '0' on 'YADP-windows-cloud'; Total containers: '0' May 28, 2018 2:07:53 PM INFO hudson.slaves.RetentionStrategy$Demand check
On the dockerhost I see following output with docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 44d92a7d90f8 jenkins/windows-ssh-slave:1.0 "cmd.exe cmd" About a minute ago Exited (0) About a minute ago vig
