srsr

Really Simple Service Registry - Python Client

Description

This is the Python client for srsr.

Usage

Typical

from srsrpy import srsrpy

# Store the client object for the lifetime of the service
c = srsrpy.ServiceRegistryClient('http://server.address.com:8080', 'service_name', 'http://client.address.net:3333')
# Returns True if registered
success = c.register()

# Carry on with the service duties. Heartbeats will be sent at the default interval.

# At teardown time, deregister
c.deregister()

Shutdown using interrupt handler

import signal
try:
    svc_reg = ServiceRegistryClient('http://server_hostname', 'service_name', 'http://client_hostname')
    svc_reg.register()

    # Assume registration was successful. Deregister on Ctrl-C
    prev_handler = signal.getsignal(signal.SIGINT)
    def handle_sigint(sig, frame):
        svc_reg.deregister()

        if prev_handler:
            prev_handler(sig, frame)
    signal.signal(signal.SIGINT, handle_sigint)
except:
    print("Couldn't connect to registry server.")

Further plans

• Publish the client to the PyPI production server
• Handle failed heartbeat, by stopping the thread.
