Linux Kernel 4.4 LTS: The 4.4 kernel is an LTS and it's great for Docker. You can also use kernel 4.9 but the kernel, like 4.13, is still too new for Docker.
Overlay2as the Docker storage driver: Although the advanced multi-layered unification filesystem (AUFS) has worked well for Docker for quite a long time, overlay2should be the new default storage driver for Docker running on the 4.4+ kernel.
