s6-overlay is an easy-to-install (just extract a tarball or two!) set of scripts and utilities allowing you to use existing Docker images while using s6 as a pid 1 for your container and process supervisor for your services.

Features

  • A simple init process which allows the end-user to execute tasks like initialization (cont-init.d), finalization (cont-finish.d) and their own services with dependencies between them
  • The s6-overlay provides proper PID 1 functionality
  • Multiple processes in a single container
  • Usable with all base images - Ubuntu, CentOS, Fedora, Alpine, Busybox...
  • Distributed as a small number of .tar.xz files depending on what exact functionality you need - to keep your image's number of layers small
  • A whole set of utilities included in s6 and s6-portable-utils. They include handy and composable utilities which make our lives much, much easier
