Hi - We are running mesos slave (0.22.0-1.0.ubuntu1404) in a docker container with docker containerizer without problems on ubuntu 14.04 docker host (with lxc-docker pkg etc added).
Running the same slave container on RHEL 7.0 docker host, the container exits almost immediately after starting with: I0613 07:18:15.161931 5303 slave.cpp:3808] Finished recovery I0613 07:18:15.162677 5303 slave.cpp:647] New master detected at [email protected]:5050 I0613 07:18:15.162753 5301 status_update_manager.cpp:171] Pausing sending status updates I0613 07:18:15.163051 5303 slave.cpp:672] No credentials provided. Attempting to register without authentication I0613 07:18:15.163734 5303 slave.cpp:683] Detecting new master W0613 07:18:15.163734 5293 logging.cpp:81] RAW: Received signal SIGTERM from process 1166 of user 0; exiting If I do not enable the docker containerized, the slave container runs fine. Other containers that bind mount /var/run/docker.sock also run fine. Debug docker logs are below. One difference between the ubuntu docker host and RHEL docker host is that the unbuntu host uses the aufs driver, while rhel uses devicemapper, and selinux is enabled in RHEL but not ubuntu. Thanks for any advice!
