Experimental Docker Libnetwork DHCP Driver

The DHCP driver is intended for users to be able to integrate Docker IP address management with their existing IPAM strategies that use DHCP for dynamic address assignment. DHCP enables users to allocate addresses in an organized fashion that will prevent overlapping IP address assignment by associating a unique MAC address from the container eth0 Ethernet interface to an IP address as determined by the DHCP pools defined in the DHCP configuration.

This driver only provides the DHCP client functionality. It does not include a DHCP server. The default driver offers single-host IPAM or for distributed multi-host orchestrated IPAM see the libnetwork overlay driver.

Writing an OS in Rust to run on RISC-V

(This is a translation of the original article in Japanese by moratorium08.)

(UPDATE (22/3/2019): Added some corrections provided by the original author.)

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.
