Containerization Strategies

Effective containerization practices for modern application deployment and orchestration.

1 October 2025 • 9 min read

Containerization has become a cornerstone of modern software deployment. In this technical guide, we'll explore best practices for container design, orchestration strategies, and performance optimization techniques.

Container Design Principles

Docker Best Practices

# Dockerfile example FROM golang:1.21 as builder WORKDIR /app COPY . . RUN CGO_ENABLED=0 go build -o /go/bin/myapp FROM gcr.io/distroless/static-debian12 COPY --from=builder /go/bin/myapp /usr/local/bin/app ENTRYPOINT ["/usr/local/bin/app"]

Kubernetes Orchestration

# Deployment example
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
  template:
    spec:
      containers:
      - name: main
        image: myregistry/myapp:latest
        ports:
        - containerPort: 8080
        resources:
          limits:
            memory: "512Mi"
            cpu: "500m"

Performance Optimization

CPU Optimization

--resources-cpu 1.5

Set CPU limits using fractional notation for precise resource allocation.

Memory Management

--memory 512Mi

Define memory limits with safety margins to prevent OOM kills.
