# tool to make adding/editing products easier

|
# PRE-REQUISITES
|
|
# 1. gitolite installed on all servers
|
|
# 2. the gitolite-admin repo is also mirrored
|
|
|
|
# run this program ONLY in a clone of a gitolite-admin repo in a committed
|
|
# state. This way a "git diff" will tell you what changed, and a "git status"
|
|
# will tell you what new files were created, and you can rollback if needed.

# ------------------------------------------------------------------------------
|
|
# adding a new host:
|
|
|
|
# $0 newhost hostname admin-username
|
|
|
|
# NOTE: this requires you to first add the newhost to the gitolite.conf file
|
|
# in the list of slaves for the admin repo. That is manually done; this
|
|
# script will not do it. You will also have to ensure that the new server
|
|
# being added has been updated and is receiving changes to the admin repo
|
|
# automatically.
|
|
|
|
# DO NOT PROCEED OTHERWISE. If necessary, check by making a dummy change to
|
|
# the admin repo and pushing, then make sure the new server has received the
|
|
# change.
|
|
|
|
# ------------------------------------------------------------------------------
|
|
# adding a new product to a master host:
|
|
|
|
# $0 newprod hostname product-name
|
|
|
|
# NOTE: the host admin must first create and propagate the
|
|
# master/host/prod.conf file (see section 3, "host admins only").
