Docker recently reorganized the Docker Engine and broke it up into different parts. The main parts are runC (https://github.com/opencontainers/runc), containerD (https://containerd.io), and Moby (https://mobyproject.org). Some of these projects were donated to other organizations to maintain. Docker, the product, is now a combination of these different projects.
Sometimes, it is necessary to build a Docker binary from the source to test a patch. It is very easy to build a Docker binary from the source. In order to build one, you will need to use the source code from the Moby project. Follow these steps to build your own binaries.
