Overview

Master Kubernetes deployments for managing containerized applications at scale, including multi-container services, resource allocation, health checks, and rolling deployment strategies.

When to Use

Container orchestration and management

Multi-environment deployments (dev, staging, prod)

Auto-scaling microservices

Rolling updates and blue-green deployments

Service discovery and load balancing

Resource quota and limit management

Pod networking and security policies

Quick Start

Minimal working example:

# kubernetes-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: api-service
  namespace: production
  labels:
    app: api-service
    version: v1
spec:
  replicas: 3
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0
  selector:
    matchLabels:
      app: api-service
  template:
    metadata:
      labels:
        app: api-service
        version: v1
      annotations:
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Use resource requests and limits

Implement health checks (liveness, readiness)

Use ConfigMaps for configuration

Apply security context restrictions

Use service accounts and RBAC

Implement pod anti-affinity

Use namespaces for isolation

Enable pod security policies

❌ DON'T

Use latest image tags in production

Run containers as root

Set unlimited resource usage

Skip readiness probes

Deploy without resource limits

Mix configurations in container images

Use default service accounts
