When using Docker Runner to isolate builds on Windows images, such as openjdk:10-jdk-windowsservercore, running in Docker for Windows, the container will fail to start:
13-Sep-2018 16:00:17 C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: network host not found.
13-Sep-2018 16:00:17 Failed to start docker container df37fa8b-e94c-43a5-8d48-f7c4d90fd10c139396235
Running the command directly without --net=host results in the container starting successfully. There is currently no way to prevent Docker Runner from using the --net=host argument.
