krux_elb is a library that provides wrapper functions for common ELB usage. It uses krux_boto to connect to AWS ELB.
The most common use case is to build a CLI script using krux_elb.cli.Application.
Here's how to do that:
import krux_elb.cli
# This class inherits from krux.cli.Application, so it provides
# all that functionality as well.
class Application(krux_elb.cli.Application):
def run(self):
print self.elb.find_load_balancers(
instance='i-a1b2c3d4'
)
def main():
# The name must be unique to the organization.
app = Application(name='krux-my-s3-script')
with app.context():
app.run()
# Run the application stand alone
if __name__ == '__main__':
main()From other CLI applications, you can make the use of krux_elb.elb.get_elb() function.
from krux_elb.elb import add_elb_cli_arguments, get_elb
import krux.cli
class Application(krux.cli.Application):
def __init__(self, *args, **kwargs):
super(Application, self).__init__(*args, **kwargs)
self.elb = get_elb(self.args, self.logger, self.stats)
def add_cli_arguments(self, parser):
super(Application, self).add_cli_arguments(parser)
add_elb_cli_arguments(parser)Alternately, you want to add ELB functionality to your larger script or application. Here's how to do that:
from krux_boto import Boto
from krux_elb import ELB
class MyApplication(object):
def __init__(self, *args, **kwargs):
boto = Boto(
logger=self.logger,
stats=self.stats,
)
self.elb = ELB(
boto=boto,
logger=self.logger,
stats=self.stats,
)
def run(self):
print self.elb.find_load_balancers(
instance='i-a1b2c3d4'
)As long as you get an instance of krux_boto.boto.Boto, the rest are the same. Refer to krux_boto module's README on various ways to instanciate the class.
