Production deployment patterns
Graceful shutdown, prod config, rollouts, readiness probes, and ship-with-confidence checks.
How to mock resource request limits in Python
A Python class that simulates CPU and memory limit checks for resource requests, returning clear acceptance or rejection messages.
class ResourceLimits:
def __init__(self, cpu_limit, memory_limit):
self.cpu_limit = cpu_limit
self.memory_limit = memory_limit
def check_request(self, cpu, memory):
if cpu > self.cpu_limit:
return "CPU limit exceeded: {cpu} > {limit}".format(cpu=cpu, limit=self.cpu_limit)
…How to simulate GitLab CI stages in Python
Build a lightweight Python mock of GitLab CI pipeline stages to test job sequencing and output locally.
def mock_gitlab_ci_stages():
stages = ["build", "test", "deploy"]
stage_status = {}
for stage in stages:
jobs = []
if stage == "build":
jobs = ["compile", "package"]
elif stage == "test":
jobs = ["unit", "integration", "e2e"]
elif stage == "deploy":…How to simulate a Jenkins pipeline in Python
Simulate a Jenkins-style pipeline in Python by running sequential stages and checking aggregate success.
def run_stage(name, duration, fn):
print(f"[Pipeline] Running stage: {name}")
result = fn()
print(f"[Pipeline] Stage '{name}' completed in {duration}s -> {result}")
return result
def build_project():
print(" compiling source...")
return "BUILD_OK"

A mock init container that runs environment checks and a staged database migration job before the main application starts, printing progress to stdout.
```python
class MigrationJob:
def __init__(self, name, steps):
self.name = name
self.steps = steps
self.current_step = 0
self.status = "pending"
def run(self):
print(f"Initializing migration job: {self.name}")
for step in self.steps:
self.current_ste…PodDisruptionBudget minAvailable in Python
Simulate a Kubernetes PodDisruptionBudget check for minAvailable and maxUnavailable constraints with a Python class.
class PodDisruptionBudget:
def __init__(self, name, min_available=None, max_unavailable=None):
self.name = name
self.min_available = min_available
self.max_unavailable = max_unavailable
def check_availability(self, ready_pods):
if self.min_available is not None:
