Production deployment patterns
Graceful shutdown, prod config, rollouts, readiness probes, and ship-with-confidence checks.
Generate a docker-compose.yml with mock services in Python
Build a docker-compose.yml string from a Python dict of service names and images, then write it to a file.
import yaml
from pathlib import Path
def generate_mock_compose(services: dict) -> str:
compose = {
"version": "3.9",
"services": {}
}
for name, image in services.items():
compose["services"][name] = {
"image": image,
"container_name": f"mock-{name}",
…How to Mock Kubernetes Services with a ClusterIP Registry in Python
Simulate Kubernetes service discovery by assigning ClusterIP addresses to dataclass-defined services, with JSON export for inspection or testing.
import json
from dataclasses import dataclass, asdict
from typing import Dict, Optional
@dataclass
class Service:
name: str
namespace: str
cluster_ip: str
selector: Dict[str, str]
port: int
target_port: Optional[int] = None
class ClusterIPServiceRegistry:
_ip_counter = 0
