seccomp for better mesos sandboxes?
I was reading a Docker security article this morning: https://opensource.com/business/15/3/docker-security-future ... and there's talk about leveraging libseccomp bindings to enhance Docker container security. It seems to me that similar security concerns probably exist for mesos deployments (using Docker or not). Has anyone thought of integrating something like this to further isolate mesos container sandboxes? For reference: https://github.com/seccomp/libseccomp -James

Slave recovery not recovering tasks when using systemd
Dear Mesos Users, I just wanted to point out a solved issue (https://issues.apache.org/jira/browse/MESOS-2419 https://issues.apache.org/jira/browse/MESOS-2419) where the systemd default behaviour prevents tasks from recovering. The problem is that the default KillMode for systemd processes is cgroup (http://www.freedesktop.org/software/systemd/man/systemd.kill.html http://www.freedesktop.org/software/systemd/man/systemd.kill.html) and hence all child processes are killed when the slave stops. Explicitly setting the KillMode to process allows the executors to survive and reconnect. Feel free to check our configuration at: https://github.com/mesosphere/mesos-deb-packaging/blob/master/systemd/slave.systemd https://github.com/mesosphere/mesos-deb-packaging/blob/master/systemd/slave.systemd Thanks, Joerg

Will the RHEL7 packages be updated in the mesosphere repository to account for this? -- Text by Jeff, typos by iPhone
