lxc - Linux container can not access device node

I used the following configuration to bind the lirc0 into the container.

lxc.mount.entry = /dev/lirc0 dev/lirc0 none bind,optional,create=file

The attribute of the /dev/lirc0 in the host as follows.

crw-------    1 root root  251,   0 Jul 16 20:00 /dev/lirc0

and I use the lxc-attach to go into the container. The attribute of the /dev/lirc0 in the container is the same as the host

crw-------    1 root root  251,   0 Jul 16 20:00 /dev/lirc0

But the /dev/lirc0 can't be open. The error is the "Operation not permitted" and I'm the supervisor(root) in the container.

How can I get the privilege to access /dev/lirc0 in the container?

Solution

  • You need to set your linux capabilities on the binary you are running.
