Deploy a cobalt site atomically from a bare git repository. This
|
||
|
|
script is intended to be run from a git `post-update` hook. It takes
|
||
|
|
two arguments:
|
||
|
|
|
||
|
|
- STAGE-DIR: The working area directory, which will be created if
|
||
|
|
it does not exist. This directory is intended to be under the
|
||
|
|
control of cobalt-git-deploy, and should be empty on the first run
|
||
|
|
of cobalt-git-deploy.
|
||
|
|
|
||
|
|
Note that cobalt-git-deploy will modify and delete files below
|
||
|
|
STAGE-DIR.
|
||
|
|
|
||
|
|
- DEPLOY-DIR: The location of a symbolic link which will be updated
|
||
|
|
to the rendered site. This location should either not exist, or
|
||
|
|
already be a symbolic link, otherwise cobalt-git-deploy will fail.
|
||
|
|
|
||
|
|
This is the directory you probably want to point the document root
|
||
|
|
of your webserver to.
|
||
|
|
|
||
|
|
# Mode of operation
|
||
|
|
|
||
|
|
cobalt-git-deploy will alternatingly use the sub-directories `left`
|
||
|
|
and `right` of STAGE-DIR to check out the contents of the current
|
||
|
|
master branch of the bare git repository, which must exist in the
|
||
|
|
current working directory. It will then build the site in one of these
|
||
|
|
directories using cobalt. If successful, DEPLOY-DIR will be updated
|
||
|
|
with a symblic link pointing to generated `_site` directory.
