Docker is a software platform that allows you to build, test, and deploy applications quickly. Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime. Using Docker, you can quickly deploy and scale applications into any environment and know your code will run.

Running Docker on AWS provides developers and admins a highly reliable, low-cost way to build, ship, and run distributed applications at any scale.

Recent announcements: Docker collaborates with AWS to help developers speed delivery of modern apps to the cloud. This collaboration helps developers use Docker Compose and Docker Desktop to leverage the same local workflow they use today to seamlessly deploy apps on Amazon ECS and AWS Fargate. Read the blog for more information.

How Docker works

Docker works by providing a standard way to run your code. Docker is an operating system for containers. Similar to how a virtual machine virtualizes (removes the need to directly manage) server hardware, containers virtualize the operating system of a server. Docker is installed on each server and provides simple commands you can use to build, start, or stop containers.

AWS services such as AWS Fargate, Amazon ECS, Amazon EKS, and AWS Batch make it easy to run and manage Docker containers at scale.

Why use Docker

Using Docker lets you ship code faster, standardize application operations, seamlessly move code, and save money by improving resource utilization. With Docker, you get a single object that can reliably run anywhere. Docker's simple and straightforward syntax gives you full control. Wide adoption means there's a robust ecosystem of tools and off-the-shelf applications that are ready to use with Docker.

Ship More Software Faster

Docker users on average ship software 7x more frequently than non-Docker users. Docker enables you to ship isolated services as often as needed.

Standardize Operations

Small containerized applications make it easy to deploy, identify issues, and roll back for remediation.

Seamlessly Move

Docker-based applications can be seamlessly moved from local development machines to production deployments on AWS.

Save Money

Docker containers make it easier to run more code on each server, improving your utilization and saving you money.

When to use Docker

You can use Docker containers as a core building block creating modern applications and platforms. Docker makes it easy to build and run distributed microservices architecures, deploy your code with standardized continuous integration and delivery pipelines, build highly-scalable data processing systems, and create fully-managed platforms for your developers. The recent collaboration between AWS and Docker makes it easier for you to deploy Docker Compose artifacts to Amazon ECS and AWS Fargate.

Microservices

Build and scale distributed application architectures by taking advantage of standardized code deployments using Docker containers.

Continuous Integration & Delivery

Accelerate application delivery by standardizing environments and removing conflicts between language stacks and versions.

Data Processing

Provide big data processing as a service. Package data and analytics packages into portable containers that can be executed by non-technical users.

Containers as a Service

Build and ship distributed applications with content and infrastructure that is IT-managed and secured.

Docker frequently asked questions

Q: What can I do with Docker?

Using Docker, you can quickly deploy and scale applications into any environment and know your code will run. You can do this because Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime.

Q: What is a Docker Image?

A Docker image is a read-only template that defines your container. The image contains the code that will run including any definitions for any libraries and dependancies your code needs. A Docker container is an instantiated (running) Docker image. AWS provides Amazon Elastic Container Registry (ECR), an image registry for storing and quickly retrieving Docker images.

Q: What is the difference between Docker and a virtual machine?

Virtual machines (VMs) virtualize (or remove the need to directly manage) server hardware while containers virtualize the operating system of a server. Docker is an operating system (or runtime) for containers. The Docker Engine is installed on each server you want to run containers on and provides a simple set of commands you can use to build, start, or stop containers.

Run Docker on AWS

AWS provides support for both Docker open-source and commercial solutions. There are a number of ways to run containers on AWS, including Amazon Elastic Container Service (ECS) is a highly scalable, high performance container management service. Customers can easily deploy their containerized applications from their local Docker environment straight to Amazon ECS. AWS Fargate is a technology for Amazon ECS that lets you run containers in production without deploying or managing infrastructure. Amazon Elastic Container Service for Kubernetes (EKS) makes it easy for you to run Kubernetes on AWS. AWS Fargate is technology for Amazon ECS that lets you run containers without provisioning or managing servers. Amazon Elastic Container Registry (ECR) is a highly available and secure private container repository that makes it easy to store and manage your Docker container images, encrypting and compressing images at rest so they are fast to pull and secure. AWS Batch lets you run highly-scalable batch processing workloads using Docker containers.

Docker has enabled download rate limits for pull requests on Docker Hub. Limits are determined based on the account type. For more information, see Resource Consumption FAQs and Docker Hub Pricing.

A user’s limit will be equal to the highest entitlement of theirpersonal account or any organization they belong to. To take advantage of this, you must log into Docker Hub as an authenticated user. For more information, seeHow do I authenticate pull requests. Unauthenticated (anonymous) users will have the limits enforced via IP.

• A pull request is defined as up to two GET requests on registry manifest URLs (/v2/*/manifests/*).
• A normal image pull makes a single manifest request.
• A pull request for a multi-arch image makes two manifest requests.
• HEAD requests are not counted.
• Limits are applied based on the user doing the pull, and not based on the image being pulled or its owner.

Docker will gradually introduce these rate limits starting November 2nd, 2020.

How do I know my pull requests are being limited

When you issue a pull request and you are over the limit for your account type, Docker Hub will return a 429 response code with the following body when the manifest is requested:

You will see this error message in the Docker CLI or in the Docker Engine logs.

How can I check my current rate

Valid manifest API requests to Hub will usually include the following rate limit headers in the response:

These headers will be returned on both GET and HEAD requests. Note that using GET emulates a real pull and will count towards the limit; using HEAD will not, so we will use it in this example. To check your limits, you will need curl, grep, and jq installed.

To get a token anonymously (if you are pulling anonymously):

To get a token with a user account (if you are authenticating your pulls) - don’t forget to insert your username and password in the following command:

Then to get the headers showing your limits, run the following:

Which should return headers including these:

This means my limit is 100 per 21600 seconds (6 hours), and I have 76 pulls remaining.

Remember that these headers are best-effort and there will be small variations.

I don’t see any RateLimit headers

If you do not see these headers, that means pulling that image would not count towards pull limits. This could be because you are authenticated with a user associated with a Legacy/Pro/Team Docker Hub account, or because the image or your IP is unlimited in partnership with a publisher, provider, or open source organization.

How do I authenticate pull requests

The following section contains information on how to log into on Docker Hub to authenticate pull requests.

Docker Desktop

If you are using Docker Desktop, you can log into Docker Hub from the Docker Desktop menu.

Click Sign in / Create Docker ID from the Docker Desktop menu and follow the on-screen instructions to complete the sign-in process.

Docker Engine

If you are using a standalone version of Docker Engine, run the docker login command from a terminal to authenticate with Docker Hub. For information on how to use the command, see docker login.

Docker Swarm

If you are running Docker Swarm, you must use the -- with-registry-auth flag to authenticate with Docker Hub. For more information, see docker service create. If you are using a Docker Compose file to deploy an application stack, see docker stack deploy.

GitHub Actions

If you are using GitHub Actions to build and push Docker images to Docker Hub, see login action. If you are using another Action, you must add your username and access token in a similar way for authentication.

Kubernetes

If you are running Kubernetes, follow the instructions in Pull an Image from a Private Registry for information on authentication.

Third-party platforms

If you are using any third-party platforms, follow your provider’s instructions on using registry authentication.

Docker Hub also has an overall rate limit to protect the application and infrastructure. This limit applies to all requests to Hub properties including web pages, APIs, image pulls, etc. The limit is applied per-IP, and while the limit changes over time depending on loadand other factors, it is in the order of thousands of requests per minute. The overall rate limit applies to all users equallyregardless of account level.

You can differentiate between these limits by looking at the error code. The “overall limit” will return a simple 429 Too Many Requests response. The pull limit returns a longer error message thatincludes a link to this page.
