Lithos

Documentation

Lithos is a process supervisor and containerizer for running services. Lithos is not intended to be system init. But rather tries to be a base tool to build container orchestration.

Features:

  • use linux namespaces and cgroups for containerization
  • immediate restart of failing processes (with rate limit of course)
  • in-place upgrade of lithos without touching child processes
  • written in Rust so memory-safe and has zero runtime dependencies

It's designed to have absolutely minimal required functionality. In particular it doesn't include:

  • an image downloader (rsync is super-cool) or builder (use any tool)
  • any network API

Running Examples

Testing it in vagrant::

vagrant up && vagrant ssh

In vagrant shell::

$ ./example_configs.sh
$ sudo lithos_tree

If you want to change containers, sources or configs of this test vagrant deployment just rerun ./example_configs.sh.

(Note: in this test deployment lithos doesn't properly reload configs, because images does not version properly. Just restart lithos_tree to apply the changes)
