project42/syslog-centos repository overview

⁠project42/syslog-centos

⁠Introduction

A docker image based on CentOS with the S6 Overlay that redirects /dev/log to stdout & stderr for docker happiness!

⁠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.
