Container-based virtualization system extending kernel functionality using kernel modules compiled by a compiling container and loaded by an application container

A computer program product comprising a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code being configured to extend kernel functionality of a kernel of a container-based virtualization system comprising a compiling container for compiling kernel modules against the kernel of the container-based virtualization system, and an application container for extending kernel functionality of the kernel using a kernel module;

• wherein the computer-readable program code, when executed by a processor, causes the application container to:
• input the kernel module to the compiling container;
• receive from the compiling container the compiled kernel module;
• and
• load the compiled kernel module to the kernel of the system for enabling the extension of the kernel functionality.

A computer system for extending kernel functionality of a kernel of a container-based virtualization system, the computer system comprising:

• a memory configured to store program code;
• and
• a processor coupled to the memory and configured to execute the program code to implement a compiling container for compiling kernel modules against the kernel of the container-based virtualization system, and an application container for extending kernel functionality of the kernel using a kernel module;
• wherein the processor is further configured to:
• control the application container to input the kernel module to the compiling container;
• control the compiling container to compile the kernel module;
• and
• control the application container to receive, from the compiling container, the compiled kernel module and to load the compiled kernel module to the kernel of the container-based virtualization system.
