     1  ### Specify isolation technology for container (--isolation)
     2  
     3  This option is useful in situations where you are running Docker containers on
     4  Windows. The `--isolation=<value>` option sets a container's isolation
     5  technology. On Linux, the only supported is the `default` option which uses
     6  Linux namespaces. On Microsoft Windows, you can specify these values:
     7  
     8  * `default`: Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value.
     9  * `process`: Namespace isolation only.
    10  * `hyperv`: Hyper-V hypervisor partition-based isolation.
    11  
    12  Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`.

    14  ### Dealing with dynamically created devices (--device-cgroup-rule)
    15  
    16  Devices available to a container are assigned at creation time. The
    17  assigned devices will both be added to the cgroup.allow file and
    18  created into the container once it is run. This poses a problem when
    19  a new device needs to be added to running container.
    20  
    21  One of the solution is to add a more permissive rule to a container
    22  allowing it access to a wider range of devices. For example, supposing
    23  our container needs access to a character device with major `42` and
    24  any number of minor number (added as new devices appear), the
    25  following rule would be added:
    26  
    27  ```
    28  docker create --device-cgroup-rule='c 42:* rmw' -name my-container my-image
    29  ```
    30  
    31  Then, a user could ask `udev` to execute a script that would `docker exec my-container mknod newDevX c 42 <minor>`
    32  the required device when it is added.
    33  
    34  NOTE: initially present devices still need to be explicitly added to
    35  the create/run command
