Permitted content and support options

• Content that runs on Docker Enterprise may be published on Docker Hub under a Verified Publisher profile. This content may also qualify to become a Docker Certified Container or Plugin image, and thus become backed by collaborative Docker/Publisher support.

• Content that runs on the Docker Community may be published in Docker Hub, but is not supported by Docker nor is it eligible to become Certified.

• Content that requires a non-Certified Infrastructure environment may not be published.

If your content:	Can publish	Can be Certified	Supported by publisher
Works on Docker Community	YES	NO	Optional
Does not work on Docker Certified Infrastructure	NO	N/A	N/A

Onboarding

The Docker Hub publishing process begins from the landing page: sign in with your Docker ID and specify a product name and image source from a private or public repository.

After specifying a source, provide the content-manifest items to populate your product details page. These items include logos, descriptions, and licensing and support links so that customers can make informed decisions about your image. These items are submitted alongside the image itself for moderation.

The Docker Hub team then conducts a comprehensive review of your image and metadata. We use Docker Security Scanning to evaluate the security of your product images, and share results with you as the publisher. During the image-moderation phase, we iterate back and forth with publishers to address outstanding vulnerabilities and content-manifest issues until the image is ready for publication.

Commercial content and other supported images may qualify for the Docker Certified Container or Plugins quality mark. The testing for this program goes beyond the vulnerability scan and also evaluates container images for Docker best practices developed over years of experience. Collaborative support capability between Docker and the publisher is also established. Refer to the diagram below for a high-level summary:

Create great content

Create your content, and follow our best practices to Dockerize it. Keep your images small, your layers few, and your components secure. Refer to the links and guidelines listed below to build and deliver great content:

• Best practices for writing Dockerfiles

• Official Images on Docker Hub

• Docker Bench for Security{: target="blank" class=""}

Here are some best practices when it comes to building vulnerability-free Docker images:

Choose a secure base image (See your Dockerfile's FROM: directive)

Many base images have a strong record of being secure, including:

• Debian{: target="blank" rel="noopener" class=""} Linux: both small and tightly-controlled, Debian-linux is a good alternative if you're currently using Ubuntu.

• Alpine{: target="blank" rel="noopener" class=""} Linux: Alpine is a minimal linux distribution with an excellent security record.

• Alpine-based application images: these include python:alpine, ruby:alpine, and golang:alpine. They are secure and minimal, while providing the convenience of their non-Alpine alternatives.

Docker strongly recommends Alpine Linux. The founder of this Linux distribution is leading an initiative at Docker to provide safe, compact base images for all container applications.

Remove unused components

Often, vulnerabilities exist in components that aren't actually used in the containerized application. To avoid this, you can:

• Follow best practices when using the apt-get command.

• Run apt-get-remove to destroy any components required to build but not actually run your application. Usually, this involves creating multi-line Dockerfile directives, as seen below. The following example shows how to remove curl and python-pip after they are used to install the Python requests package, all in a single Dockerfile directive:

  RUN apt-get update && \
           apt-get install -y --no-install-recommends curl python-pip && \
           pip install requests && \
           apt-get remove -y python-pip curl && \
           rm -rf /var/lib/apt/lists/
  

Files introduced in one directive of your Dockerfile can only be removed in the same directive (and not in subsequent directives in your Dockerfile).

Keep required components up-to-date

Your images are composed of open-source libraries and packages that amass vulnerabilities over time and are consequently patched. To ensure the integrity of your product, keep your images up-to-date:

• Periodically update your base image's version, especially if you’re using a version deemed to be vulnerable.

• Re-build your image periodically. Directives including commands such as apt-get install ... pull the latest versions of dependencies, which may include security fixes.

Create and maintain your Verified Publisher profile

Let the Docker community know who you are. Add your details, your company story, and what you do. At the very minimum, we require:

• Legal entity name
• Company website
• Phone number
• Valid company email
• Company icon/logo (square; at least 512x512px)

Prepare your image-manifest materials

You must provide the namespace (including repository and tags) of a private or public repository on Docker Hub that contains the source for your product. This repository path is not shown to users, but the repositories you choose determine the Product Tiers available for customers to download.

The following content information helps us make your product look great and discoverable:

1. Product Name
2. Product icon/logo
3. Short description: a one-to-two-sentence summary; up to 140 characters
4. Category: Database, Networking, Business Software, etc. and any search tags
5. Long description: includes product details/pitch
6. Screenshot(s)
7. Support link
8. Product tier name
9. Product tier description
10. Product tier price
11. Installation instructions
12. Link to, or text of, license agreements

How the manifest information is displayed in the UI

This is an approximate representation, and some elements might shift around as we make enhancements.

Support your users

Docker users who download your content might need help later, so be prepared for questions! The information you provide with your submission saves support time in the future.

Support information

If you provide support along with your content, include that information. Is there a support website? What email address can users contact for help? Are there self-help or troubleshooting resources available?

Support SLA

Include a Service Level Agreement (SLA) for each image you're offering. An SLA is your commitment to your users about the nature and level of support you provide to them. Make sure your SLA includes support hours and response-time expectations, where applicable.

Security and audit policies

Docker Hub audits consumer activity of your images to provide you intelligence about the use of your product.

Usage audit and reporting

Unless otherwise negotiated, an audit of activity on publisher content is retained for no less than 180 days.

A monthly report of said activity is provided to the publisher with the following data: (1) report of content download by free and paid customers by date and time; (2) report of purchase, cancellations, refunds, tax payments, where applicable, and subscription length for paid customers of the content; and (3) the consolidated amount to be received by the publisher.

Certification

There are three types of certification that appear in Docker Hub.

Certifies that a container image on Docker Hub has been tested; complies best practices guidelines; runs on Docker Certified Infrastructure; has proven provenance; been scanned for vulnerabilities; and is supported by Docker and the content publisher

This certification is designed for volume, network, and other plugins that access system level Docker APIs. Docker Certified Plugins provide the same level of assurance as a Docker Certified Container, but go further by having passed an additional suite of API compliance testing.

Docker Certified Publisher FAQ

What is the Docker Certified program?

Docker Certified Container images and plugins are meant to differentiate high quality content on Docker Hub. Customers can consume Certified Containers with confidence knowing that both Docker and the publisher stands behind the solution. Further details and an application can be found here.{: target="blank" rel="noopener" class=""}.

What are the benefits of Docker Certified?

Docker Hub promotes Docker Certified Containers and Plugins running on Docker Certified Infrastructure trusted and high quality content. The Docker Certified badge can also be listed alongside external references to your product.

How is support handled?

All Docker Certified Container images and plugins running on Docker Enterprise come with support provided directly by the publisher, under your existing SLA. Normally, a customer contacts the publisher for container and application level issues. Likewise, a customer contacts Docker for Docker Enterprise support. In the case where a customer calls Docker (or vice versa) about an issue on the application, Docker advises the customer about the publisher support process and performs a handover directly to the publisher if required. TSAnet is required for exchange of support tickets between the publisher and Docker.

How does a publisher apply to the Docker Certified program?

Start by applying to be a Docker Technology Partner{: target="blank" rel="noopener" class=""}

What is the difference between Official Images and Docker Certified?

Official Images is a program sponsored by Docker for the curation and packaging of Open Source Software. While upstream vendors are sometimes involved, this is not always the case. Docker Certified content is explicitly provided, maintained, and supported directly by the ISV.

How is certification of plugins handled?

Docker Certification program recognizes the need to apply special scrutiny and testing to containers that access system level interfaces like storage volumes and networking. Docker identifies these special containers as “Plugins” which require additional testing by the publisher or Docker.
