Docker Hub vs Google Container Registry: What are the differences?

Introduction

In this article, we will discuss the key differences between Docker Hub and Google Container Registry.

Docker Hub: Docker Hub is a cloud-based registry service provided by Docker that allows users to store, manage, and distribute Docker container images. It serves as a central repository for both official Docker images and user-created images. Docker Hub provides a wide range of features and integrations, such as automated builds, image vulnerability scanning, webhooks, and access control management.
Google Container Registry: Google Container Registry is a managed private Docker image storage service offered by Google Cloud Platform. It is designed to store, manage, and secure Docker container images securely. Google Container Registry integrates seamlessly with other Google Cloud services, such as Kubernetes Engine, Cloud Run, and Cloud Build. GCR provides built-in image vulnerability scanning, access control, and provides support for private and public images.
Hosting Environment: Docker Hub allows users to store and share images privately or publicly using a single registry. In contrast, Google Container Registry provides separate registries for different hosting environments like Google Cloud Platform projects. Each registry has its own access control and permissions management.
Price and Storage: Docker Hub offers free and paid plans for storing and managing container images. The free plan provides limited storage and access to some features, while the paid plans offer larger storage limits and additional functionality. On the other hand, Google Container Registry pricing is tied to the overall usage of Google Cloud services, including container storage, and follows the pricing structure of Google Cloud Platform.
Integration with Google Cloud Services: Google Container Registry seamlessly integrates with other Google Cloud services, making it well-suited for deploying containerized applications on Google Cloud Platform. It provides built-in support for Kubernetes Engine, Cloud Build, and Cloud Run, enabling developers to build and deploy applications easily using these services. Docker Hub, on the other hand, does not provide such tight integration with Google Cloud services.
Enterprise-level Support: Google Container Registry offers enterprise-level support through the Google Cloud support team, which provides assistance for any issues or inquiries with the registry. This level of support ensures reliability and timely resolutions for critical business applications hosted on Google Cloud Platform. Docker Hub also offers a support plan, but it may not have the same level of expertise and dedicated support as Google Cloud support.

In summary, Docker Hub is a popular general-purpose container registry with a wide range of features and integrations, while Google Container Registry is a managed private Docker image storage service tightly integrated with Google Cloud Platform, providing additional support, security, and integration capabilities specific to Google Cloud services.

What are some alternatives to Docker Hub, Google Container Registry?

Kubernetes

Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.

Rancher

Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.

Docker Compose

With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.

Docker Swarm

Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.

Tutum

Tutum lets developers easily manage and run lightweight, portable, self-sufficient containers from any application. AWS-like control, Heroku-like ease. The same container that a developer builds and tests on a laptop can run at scale in Tutum.

Portainer

It is a universal container management tool. It works with Kubernetes, Docker, Docker Swarm and Azure ACI. It allows you to manage containers without needing to know platform-specific code.

Codefresh

Automate and parallelize testing. Codefresh allows teams to spin up on-demand compositions to run unit and integration tests as part of the continuous integration process. Jenkins integration allows more complex pipelines.

CAST.AI

It is an AI-driven cloud optimization platform for Kubernetes. Instantly cut your cloud bill, prevent downtime, and 10X the power of DevOps.

k3s

Certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. Supports something as small as a Raspberry Pi or as large as an AWS a1.4xlarge 32GiB server.

Flocker

Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.
