Dns Management

Handles DNS configuration for Route53, Azure DNS, or CloudFlare with a focus on high availability patterns. You'll want this when setting up failover between regions, doing geo-based routing, or managing zero-downtime migrations. The examples cover health check configuration, weighted routing for canary deployments, and DNS-based traffic management. The best practices section is solid on TTL strategy and the reminder not to touch DNS during active incidents. It's infrastructure work that's easy to get wrong, so having reference implementations for failover scripts and monitoring validation is genuinely helpful. The CloudFlare and Azure coverage means you're not locked into AWS.

Overview

Implement DNS management strategies for traffic routing, failover, geo-routing, and high availability using Route53, Azure DNS, or CloudFlare.

When to Use

Domain management and routing
Failover and disaster recovery
Geographic load balancing
Multi-region deployments
DNS-based traffic management
CDN integration
Health check routing
Zero-downtime migrations

Quick Start

Minimal working example:

# route53-setup.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: route53-config
  namespace: operations
data:
  setup-dns.sh: |
    #!/bin/bash
    set -euo pipefail

    DOMAIN="myapp.com"
    HOSTED_ZONE_ID="Z1234567890ABC"
    PRIMARY_ENDPOINT="myapp-primary.example.com"
    SECONDARY_ENDPOINT="myapp-secondary.example.com"

    echo "Setting up Route53 DNS for $DOMAIN"
