What this skill does
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) Instructions 1. Identify the target registry type: ECR, Artifact Registry, ACR, Docker Hub, or self-hosted 2. Configure authentication: set up credential helpers for automated access (docker-credential-ecr-login, gcloud auth configure-docker) 3. Define image naming and tagging strategy: use semantic versioning for releases, git SHA for CI builds, latest only for development 4. Create repository/namespace structure organized by team, application, or environment 5. Configure lifecycle policies to auto-delete untagged images and images older than retention threshold (e.g., keep last 10 tagged images, delete untagged after 7 days) 6. Set up vulnerability scanning: enable automatic scanning on push (ECR scan-on-push, GCP Container Analysis) 7. Configure cross-region replication for disaster recovery and latency reduction 8. Implement access control: read-only for CI pull, push access for CI build agents, admin for operators 9. …
