VyOS Git Commit & Push on Commit
#!/bin/vbash
# file: 99-git-commit
# description: Saves config commands & config json to files, commits to local
# git repo. Repo stored in /config/user-data/$CONFIG_REPO. Completes
# process with a push to the remote repo.
#
# This script is intended to be used as a post-commit hook, allowing
# for automated config backup in a git repo.
#
# Install in /config/scripts/commit/post-hooks.d/ to run automatically
# after each VyOS commit.
#
# Repository path. You shouldn't need to modify this. This location is persistent
# across reboots and upgrades in VyOS.
REPO_PATH=/config/user-data
# Set your CONFIG_REPO directory name. This should be an git existing repository.

# Timestamp format (YYYY-MM-DDTHH:mm:ss Z)
TIMESTAMP="$(date '+%Y-%m-%dT%H:%M:%S %Z')"
# Below you have two options:
# OPTION 1 (DEFAULT BEHAVIOR): Set a commit message before committing VyOS changes by
# setting the environment variable $M. Otherwise we'll use a generic commit message if
# $M is empty.
#
# OPTION 2: Prompt for a git commit message every time this script is run (i.e., after
# every VyOS commit). To use OPTION 2, commend out lines 37-41 and uncomment lines
# 44 & 45.
#
# Use generic commit message unless variable "$M" is set (e.g., M="message here" commit;save)
