From 90858ead45f6702bdde31671246ad9c56fc7803e Mon Sep 17 00:00:00 2001 From: Malfurious Date: Fri, 15 Sep 2023 06:02:18 -0400 Subject: gitolite: Refactor Dockerfile for debian base Building from debian:latest will make for a smaller image, a faster build, and will make the image more accessible to a wider variety of platforms. The effort started by 19e7dc8932c is expanded upon such that the image cleanly bakes in all static config files into the image - ie. the entire hosting user's home directory, except for the repositories directory. This removal of config management from the gitolite-admin repo is part of the reason why it is being decoupled from this repo. The gitolite image will now never utilize a user pubkey during build. Instead, it can be invoked with an alternative entrypoint to interactively configure a new install.
