Managing Container Registries

Overview

Manage container registries across Docker Hub, AWS ECR, GCP Artifact Registry, Azure ACR, and self-hosted registries (Harbor, Nexus). Automate image tagging, lifecycle policies, cross-region replication, vulnerability scanning integration, and access control for container image storage and distribution.

Prerequisites

• Docker CLI installed and authenticated to the target registry
• Cloud provider CLI (aws, gcloud, az) for managed registries
• Registry credentials configured (docker login or credential helpers)
• Understanding of image naming conventions (registry/namespace/image:tag)
• IAM permissions for registry operations (push, pull, delete, admin)
