# Hook to check server against list of checks specified in CHECKS file. Each
|
|
# check is a relative path and, optionally, expected content.

|
|
# / My Amazing App
|
|
# /stylesheets/index.css .body
|
|
# /scripts/index.js $(function()
|
|
# /images/logo.png
|
|
#
|
|
# Waits 5 seconds, giving server time to start, before running the checks. For
|
|
# shorter/longer wait, change the DOKKU_CHECKS_WAIT environment variable (value
|
|
# in seconds).
