[jira] [Created] (MESOS-7268) CNI isolator should mount network related /etc/* files in readonly mode

Silas Snider created MESOS-7268:
-----------------------------------

             Summary: CNI isolator should mount network related /etc/* files in readonly mode
                 Key: MESOS-7268
                 URL: https://issues.apache.org/jira/browse/MESOS-7268
             Project: Mesos
          Issue Type: Bug
          Components: containerization, network
            Reporter: Silas Snider
            Assignee: Silas Snider


The CNI isolator bind mounts, even for containers using host networking, several files from /etc, such as resolv.conf. These should be mounted as readonly inside the container to prevent users running inside the container as root from being able to affect the external machine.
