Overview

Implement comprehensive container registry management including image scanning, vulnerability detection, retention policies, access control, and multi-region replication.

When to Use

• Container image storage and distribution
• Security scanning and compliance
• Image retention and cleanup
• Registry access control
• Multi-region deployments
• Image signing and verification
• Cost optimization

Quick Start

Minimal working example:

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

    REGISTRY_NAME="myapp"
    REGION="us-east-1"
    ACCOUNT_ID="123456789012"

    echo "Setting up ECR repository..."

    # Create ECR repository
    aws ecr create-repository \
      --repository-name "$REGISTRY_NAME" \
      --region "$REGION" \
      --encryption-configuration encryptionType=KMS,kmsKey=arn:aws:kms:$REGION:$ACCOUNT_ID:key/12345678-1234-1234-1234-123456789012 \
      --image-tag-mutability IMMUTABLE \
      --image-scanning-configuration scanOnPush=true || true

// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Scan images before deployment
• Use image tag immutability
• Implement retention policies
• Control registry access with IAM
• Sign images for verification
• Replicate across regions
• Monitor registry storage
• Use private registries

❌ DON'T

• Push to public registries
• Use latest tag in production
• Allow anonymous pulls
• Store secrets in images
• Keep old images indefinitely
• Push without scanning
• Use default credentials
• Share registry credentials
