Hi guys, I am afraid of a security issue with Docker. Sorry but I have no other machines to test for now, so it might be a local issue only. I realized that today when running an Ubuntu container : % docker run -ti --rm --hostname=ubuntu --net=host ubuntu /bin/bash It runs a bash shell inside the Ubuntu container. But, from within the container (screenshot attached): % apt update # should fail, not finding the command % zypper refresh # unexpectedly, it would work and refresh the host repos! Of course, this is absolutely abnormal and I am still evaluating the exact impact. I can tell that the issue was not here one week ago (I have been a quite intensive Docker user for around 2 years). So I am not sure what is causing this behavior. Looking forward to reading some feedbacks. Best regards, -- Jean-Christophe
