Overview

Deploy new versions gradually to a small percentage of users, monitor metrics for issues, and automatically rollback or proceed based on predefined thresholds.

When to Use

Low-risk gradual rollouts
Real-world testing with live traffic
Automatic rollback on errors
User impact minimization
A/B testing integration
Metrics-driven deployments
High-traffic services

Quick Start

Minimal working example:

# canary-deployment-istio.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp-v1
  namespace: production
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
      version: v1
  template:
    metadata:
      labels:
        app: myapp
        version: v1
    spec:
      containers:
        - name: myapp
          image: myrepo/myapp:1.0.0
          ports:
            - containerPort: 8080
