How to Mock a Service Mesh Sidecar Proxy in Python
Simulate a service mesh sidecar proxy with route registration, service discovery, and request proxying using a simple Python class.
class SidecarProxy:
def __init__(self, name):
self.name = name
self.routes = {}
self.services = {}
self.requests_processed = 0
def register_service(self, service_name, address, port):
self.services[service_name] = f"{address}:{port}"

Simulate a sidecar logger that tracks request counts, error rates, and endpoint hits, producing a metrics snapshot.
import random
import time
from collections import defaultdict
class SidecarLogger:
def __init__(self):
self.metrics = defaultdict(int)
self.total_requests = 0
self.error_count = 0
def log_request(self, endpoint, status_code):
