Mesos 0.21.0 introduces an optional shared filesystem isolator for the Mesos Containerizer. The isolator does not provide full filesystem encapsulation like Docker. It is intended for deployments where containers share the host’s root filesystem but certain parts of the filesystem should be made private to each container. One example use-case is a private /tmp directory for each container. Processes running in the container will see a normal /tmp directory but it actually refers to a subdirectory of the executor work directory, e.g., the relative path ./tmp. Processes will not be able to see files in the host’s /tmp directory or the /tmp directory of any other container. This isolator is available only on Linux.
