dkavanagh / http redirect example
Last active December 18, 2015 09:18
http redirector that works with tornado. start_redirector (in my code) gets called in a background thread.. ignore the callback arg, which is None, but kwargs is passed in containing use_ssl and port as values for the redirect handler.
def start_redirector(kwargs, callback):
# can't use tornado for this (not threadsafe). Must use something else, something simpler!
http_port = 8888
if eucaconsole.config.has_option('server', 'http.port'):
http_port = eucaconsole.config.getint('server', 'http.port')
server = BaseHTTPServer.HTTPServer(('localhost', http_port),
lambda *args: RedirectHandler(kwargs, *args))
server.serve_forever()
class RedirectHandler(BaseHTTPRequestHandler):

This script creates test users that are the same as created by eucalyptus ui tests. So, if you're setting up a test cloud by some other means (like kickstarting a package-built cloud), you can run this after getting the admin credentials.

Dual Pwm controller w/ display
/*
This sketch illustrates how to use an arduino to provide 2 PWM signals for motor
controllers. The LCD display shows the values as driven by pot inputs. It also has
the ability to lock the two outputs to the left input pot.
The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4

This script generates a self-signed SSL cert and creates a Eucalyptus Management Console deployment using it (with ELB and AS services). It pulls in a CloudFormations template as well https://gist.github.com/dkavanagh/8cc932f0688b909547fe
