docker-sssd's Introduction

SSSD

Abstract

Docker Image with sssd, kerberos and enroll.py that joins the container on startup using the supplied variables.

Enrollment procedure ends with SSHD starting up, making the container available on port 22 (redirected to port 2223 in the example below). If you want to debug as root - start the container with a /bin/bash instead of /usr/local/bin/enroll.py, edit enroll.py and comment out the sshd() in the last row.
