Simple demo of Integration-Manager workflow that can be used when services like Gitlab are not available.

git-demo.sh

#!/bin/bash

# This is a simple script to walk through the Integration-manager style of
# git workflow.  Without a server such as gitlab, having only standard file
# system access, this is what is necessary.
demodir=~/repos/demo
gold=$demodir/repo-gold
silver=$demodir/repo-silver
bronze=$demodir/repo-bronze
sandbox=$demodir/repo-sandbox

# gold is production area and takes final approved changed from silver
# silver is gold staging area and takes changes from user bronze area
# bronze is individual user staging area for silver and is not for WIP
# sandbox is individual user sandbox where all WIP takes place

# if you have never used git, create some git configs
if [[ ! -e ~/.gitconfig ]]; then
    # These are required
    git config --global user.name "Your Name"
    git config --global user.email "your.name@globalfoundries.com"
    # these are helpful

    git config --global alias.rlog 'log --oneline --decorate --all --reverse'

# report them as untracked
