ergomentum/centos repository overview

⁠Ergomentum CentOS

Provides an up to date full-fledged CentOS image build from scratch.

This image contains yum⁠ to install additional RPM packages. Only documentations, caches and additional locales are omitted. This may be helpful to use Docker images in a Linux distribution way where you can hook into the container and run ad hoc commands for development and debugging purposes. Consider to use not a full-fledged Linux distribution in your Docker containers for production. Starting from a Linux distribution you can use a multi stage build⁠ and remove everything you don't need. Or compile the executable statically linked from scratch.

For this image yum⁠ will be configured to run all commands in non interactive mode and to skip the installation of documentation files.

CentOS v7 use a MAJOR.MINOR.PATCH version schema⁠ with a date code YYMM as PATCH version. But effectively there are no PATCH releases although continuously patched RPMs are released.

Contrary to the official one you can use this docker image as up to date one without floating tags^[1]⁠ like latest, centos7 to ensure reproducible builds.
