# An example upstart script for running a Node.js process as a service
# using Forever as the process monitor. For more configuration options
# associated with Forever, see: https://github.com/nodejitsu/forever
#
# You will need to set the environment variables noted below to conform to
# your use case, and should change the description.

# This line is needed so that Upstart reports the pid of the Node.js process
# started by Forever rather than Forever's pid.

# The following environment variables must be set so as to define
# where Node.js and Forever binaries and the Node.js source code
# can be found.
#
# The example environment variables below assume that Node.js is
# installed into /home/node/local/node by building from source as outlined
# here:

# It should be easy enough to adapt to the paths to be appropriate to a
# package installation, but note that the packages available for Ubuntu in
# the default repositories are far behind the times. Most users will be
# building from source to get a more recent Node.js version.

# The full path to the directory containing the node and forever binaries.

# Set the NODE_PATH to the Node.js main node_modules directory.

# The minUptime and spinSleepTime settings stop Forever from thrashing if
# the application fails immediately on launch. This is generally necessary to
# avoid loading development servers to the point of failure every time
# someone makes an error in application initialization code, or bringing down
# production servers the same way if a database or other critical service
# suddenly becomes inaccessible.

# Here we're using the pre-stop script to stop the Node.js application
# process so that Forever is given a chance to do its thing and tidy up
# its data. Note that doing it this way means that each application that
# runs under Forever must have a different start file name, regardless of
# which directory it is in.
