About specialized hardware and driver enablement

You can use driver containers to build and deploy out-of-tree kernel modules and drivers on container operating systems such as FCOS. These kernel modules and drivers are software libraries that run with a high level of privilege in the operating system kernel. They extend the kernel functionalities or provide the hardware-specific code required to control new devices. Examples include hardware devices such as field-programmable gate arrays (FPGA) or graphics processing units (GPU), and software-defined storage solutions, which all require kernel modules on client machines. Driver containers are the first layer of the software stack to enable these technologies on OKD deployments.
