Hi, Now I understand what you are referring to: --net=host let docker use host networking . It took a while ;-)
Actually, on our x86_64 ci we are using container networking with a sonatype nexus container as a caching proxy for maven artifacts. This results in sharing the network with all compile jobs on the same host. We had big problems with that in the past related to insane compile projects interfering with each other: The spark version 1 and spark version 2 jobs running on the same host mixed their network based nailgun scala compilation service since they are on the same network. This is fixed by us by turning nailgun off. When we switch on --net=host, every compile job opening up services is not only visible to each other, it is exposed to the internet, but it is essentially the same as running a compile job on the host itself. Let's try it for compilation. However, the docker provisioner will not work that way.
