#### **--device**=*host-device[:container-device][:permissions]*
|
|
|
|
Add a host device to the <<container|pod>>. Optional *permissions* parameter
|
|
can be used to specify device permissions by combining
|
|
**r** for read, **w** for write, and **m** for **mknod**(2).
|
|
|
|
Example: **--device=/dev/sdc:/dev/xvdc:rwm**.
|
|
|
|
Note: if *host-device* is a symbolic link then it is resolved first.
|
|
The <<container|pod>> only stores the major and minor numbers of the host device.
|
|
|
|
Podman may load kernel modules required for using the specified
|
|
device. The devices that Podman loads modules for when necessary are:
|
|
/dev/fuse.
|
|
|
|
In rootless mode, the new device is bind mounted in the container from the host
|
|
rather than Podman creating it within the container space. Because the bind
|
|
mount retains its SELinux label on SELinux systems, the container can get
|
|
permission denied when accessing the mounted device. Modify SELinux settings to
|
|
allow containers to use all device labels via the following command:
|
|
|
|
$ sudo setsebool -P container_use_devices=true
