# This script is intended to be called by the script service and to be
|
|
# connected to a socket using a service configuration like this:
|
|
# executable = script -p /path/to/health-check.sh
|
|
#
|
|
# This simple example merely answers "PONG\n" if the input is "PING\n". It
|
|
# stops waiting for input after $timeout which causes the process to die
|
|
# which causes the script module to close the socket. Inputs and outputs
|
|
# can be written to STDIN and STDOUT, they are duplicated file-descriptors
|
|
# if called from the script service.
