Appendix A. LXC Alternatives to Docker and OpenVZ

LXC is designed and ideally suited for running full system containers; this means that an LXC instance contains the filesystem of an entire operating system distribution, very similar to a virtual machine. Even though LXC can run a single process, or a replacement of the init system with a custom script, there are other container alternatives that are better suited for executing just a single, self-contained program. In this Appendix, we are going to look at two container implementation alternatives to LXC that can run side by side with LXC – Docker and OpenVZ.
