(Updated July 7, 2015, 11:33 a.m.) Review request for mesos, Chi Zhang, Dominic Hamon, Jay Buffington, Jie Yu, and James Peach. Bugs: MESOS-2350 https://issues.apache.org/jira/browse/MESOS-2350 Repository: mesos Description ------- Optionally take a path that the launch helper should chroot to before exec'ing the executor. It is assumed that the work directory is mounted to the appropriate location under the chroot. In particular, the path to the executor must be relative to the chroot. Configuration that should be private to the chroot is done during the launch, e.g. mounting proc and statically configuring basic devices. It is assumed that other configuration, e.g., preparing the image, mounting in volumes or persistent resources, is done by the caller. Mounts can be made to the chroot (e.g., updating the volumes or persistent resources) and they will propagate in to the container but mounts made inside the container will not propagate out to the host. It currently assumes that at least {{chroot}}/tmp is writeable and that mount points {{chroot}}/{tmp,dev,proc,sys} exist in the chroot. This is specific to Linux.

This is harder to automate because we need a self-contained chroot to execute something in... Suggestions welcome. Thanks, Ian Downes
