Kubernetes Patterns

Production-grade Kubernetes deployment and pod design patterns.

Pod Design Patterns

# Sidecar Pattern: log collector alongside main app
apiVersion: v1
kind: Pod
metadata:
  name: app-with-sidecar
spec:
  containers:
    - name: app
      image: myapp:v1.2.0
      ports:
        - containerPort: 8080
      volumeMounts:
        - name: logs
          mountPath: /var/log/app

    - name: log-collector
      image: fluentd:v1.16
      volumeMounts:
        - name: logs
          mountPath: /var/log/app
          readOnly: true

  volumes:
    - name: logs
      emptyDir: {}

Init Containers

# Run setup tasks before main container starts
apiVersion: apps/v1
kind: Deployment
