Container registry
A container registry is a service or repository for storing, managing, and distributing container images and related artifacts.
Learn Docker in a Month of Lunches, Second Edition
A container registry is a service that stores and distributes container images.
- How it is used
- Distributes container images between development machines, build pipelines, and deployment environments.
- How deep it goes
- Works through image references, login, tagging, pushing, local-registry setup, and cloud use; it does not detail registry server internals.
- Examples
- Uses Docker Hub image pulls and pushes, a registry container, Azure Container Registry, and GitHub Container Registry staging images.
- What you can do after
- Operate/configure a registry workflow to tag, push, and pull images through Docker Hub or a local registry.

Bootstrapping Microservices, Second Edition: With Docker, Kubernetes, GitHub Actions, and Terraform
A container registry is a service that stores, manages, and distributes container images, with access controls such as private repositories.
- How it is used
- Provides a private cloud location for publishing microservice images that a Kubernetes cluster can obtain for deployment.
- How deep it goes
- Works through registry creation, authentication, tagging, pushing, pull validation, and cluster access; does not detail registry service internals.
- Examples
- Uses a video-streaming image, Azure Container Registry, Docker commands, a Terraform registry resource, and an AcrPull role assignment.
- What you can do after
- Operate/configure a private Azure registry, publish an image with Docker, and make it available to a cloud Kubernetes cluster.
Podman in Action: Secure, rootless containers for Kubernetes, microservices, and more
A container registry is a service that stores, distributes, and serves container images.
- How it is used
- Stores and distributes container images for Podman workflows that build, run, share, and deploy containerized applications.
- How deep it goes
- Traces image layers, manifests, transports, and runtime handoff while deferring advanced registry controls to later treatment.
- Examples
- Demonstrates quay.io, docker.io, registry.access.redhat.com, short-name selection, podman pull, podman run, and podman push.
- What you can do after
- Operate/configure registries by pulling, pushing, naming, selecting, inspecting, and controlling image sources with Podman.
Road to Kubernetes
A container registry is a storage and distribution service for container images.
- How it is used
- Supports packaging, sharing, and deploying container images across machines and production systems.
- How deep it goes
- Explains registry purpose, default behavior, account setup, authentication, image tagging, and pushing, but defers self-hosted registry operation.
- Examples
- Uses Docker Hub, the official NGINX image, docker run nginx, and a tagged Python application image.
- What you can do after
- Operate Docker Hub by logging in, building a tagged image, pushing it, and pulling images for container execution.
Kubernetes for Developers
A container repository is a storage location that stores and distributes container images identified by image names and tags.
- How it is used
- Supplies Kubernetes with container images that were built locally and must run in a cloud cluster.
- How deep it goes
- Explains storage, visibility, authentication, provider choice, tagging, and pushing, but stops short of registry internals.
- Examples
- Uses Docker Hub, Artifact Registry, tagged timeserver images, docker push, and versioned repository paths.
- What you can do after
- Build and upload a versioned container image that Kubernetes can fetch for deployment.

Kubernetes in Action, Second Edition
A container registry is a repository service that stores and distributes container images to authorized clients.
- How it is used
- Distributes container images between developers, computers, and application environments.
- How deep it goes
- Explains storage, public versus private access, pushing, pulling, and container creation without detailing registry internals.
- Examples
- Uses the build, push, pull, and run flow across two Docker-enabled computers.
- What you can do after
- Operate Docker image distribution by pushing images to a registry and pulling them to create containers.

Google Anthos in Action
A Docker registry is a service that stores and distributes Docker container images.
- How it is used
- Stores and distributes container images while supporting vulnerability scanning and cluster admission controls.
- How deep it goes
- Explains API enablement, repository creation, regional authentication, and registry admission testing, but defers detailed image tagging and pushing.
- Examples
- Uses gcloud repository commands, regional Docker authentication, approved-registry constraints, and rejected or dry-run Kubernetes workloads.
- What you can do after
- Operate/configure a GCP Docker repository and assess registry restrictions with Gatekeeper policies.

Spring in Action, Sixth Edition
A container registry is a service that stores and distributes container images.
- How it is used
- Deploys a built Spring Boot container image by naming it for a DockerHub repository and pushing it there.
- How deep it goes
- Explains image tags, Maven and Gradle configuration, and pushing, but does not detail registry internals.
- Examples
- Uses the tacocloud repository, versioned image tags, Spring Boot build commands, and docker push.
- What you can do after
- Operate/configure a Spring Boot build to create and publish a repository-tagged Docker image.
