⁠Introduction

A docker image based on CentOS Linux with the s6 process supervisor

⁠What is CentOS Linux?

Community Enterprise Operating System (CentOS) is a community-driven free software effort focused on delivering a robust, open source, enterprise class Linux distribution functionally compatible upstream with Red Hat Enterprise Linux (RHEL) sources.

⁠What is the s6-overlay?

The s6-overlay project⁠ is a series of init scripts and utilities to ease creating Docker images using s6 as a process supervisor. The s6-overlay makes it easy to take advantages of s6 while still operate like other Docker images. The s6 init system provides many helpful tools to initialize and manage processes as the Docker container starts.

A working docker daemon would be helpful to utilize this image.

⁠How to use this image

This image is meant to be used as a base to build custom docker images from. It's value is that it takes the base CentOS linux image and adds the s6 overlay.

⁠Usage

⁠Running a quick CentOS linux container

docker run --rm -ti project42/s6-centos:latest bash

This will present you with a shell on fresh container that will stop and remove itself when you exit the container.
