Mounting System Resources

Mounting Files:

Ruri has powerful built-in mounting options. You can use -m to mount a file, and -M to mount it as read-only.

Directories:

For example, -m /sdcard /sdcard mounts the host machine’s /sdcard to the container’s /sdcard. However, this is not secure. The recommended approach is to use -M /sdcard /sdcard for read-only mounting.

Block Devices:

For example, you can use -m /dev/sda /mnt to mount /dev/sda to /mnt.

Image Files:

For example, you can use -m ./1.img /mnt to mount ./1.img to /mnt.

Root Directory:

Use -m resource / to pre-mount the root directory. For instance, -m ./rootfs.img / can mount ./rootfs.img as the container’s root directory.

Other Files:

Ruri also supports mounting individual files. For example, -m /tmp/1.sock /tmp/1.sock is theoretically possible.

Adding Character Devices:

Ruri supports adding character devices under /dev using -I filename major_number minor_number. For example, -I kvm 10 232 or -I dri/card0 226 0.
