With DockerCon just a day away, let’s not forget to give a big THANK YOU to all our sponsors.
As our ecosystem partners, they play a central role in our strategy to deliver the best developer experience from local desktop to cloud, and/or to offer best-in-class solutions to help you build apps faster, easier and more securely. Translation: We couldn’t do what we do without them.
So be sure to visit their virtual rooms and special sessions at DockerCon this Thursday, May 27. With more than 20 Platinum, Gold or Silver sponsors this year, you’ll have plenty to choose from.
For example, check out AWS’s virtual room and the session with AWS Principal Technologist Massimo Re Ferrè at 3:15 p.m.-3:45 p.m. PDT.
And check out Microsoft’s virtual room and any of the three sessions it’s offering — How to Package DevOps Tools Using Docker Containers (3:45 p.m.- 4:15 p.m.), Container-Based Development with Visual Studio Code (4:15 p.m.- 4:45 p.m.), and Supercharging Machine Learning Development with Azure Machine Learning and Containers in VS Code! (4:45 p.m.- 5:15 p.m.).
Today, Docker and JFrog announced a new partnership to ensure developers can benefit from integrated innovation across both companies’ offerings. This partnership sets the foundation for ongoing integration and support to help organizations increase both the velocity and quality of modern app development.
The objective of this partnership is simple: how can we ensure developers can get the images they want and trust, and make sure they can access them in whatever development process they are using from a centralized platform? To this end, the new agreement between Docker and JFrog ensures that developers can take advantage of their Docker Subscription and Docker Hub Official Images in their Artifactory SaaS and on-premise environments so they can build, share and run apps with confidence.
At a high level, a solution based on the Docker and JFrog partnership looks like this:
In this sample architecture, developers can build apps with images, including Docker Official Images and images from popular OSS projects and software companies, from Docker Hub. As images are requested, they are cached into JFrog Artifactory, where images can be managed by corporate policies, cached for high performance, and mirrored across an organization’s infrastructure. Also, the images in Artifactory can take Continue reading
As the calendar leaves 2020 in the rear view mirror, we’re looking forward to the year ahead. And as part of this, today we’re announcing the dates for DockerCon Live 2021. DockerCon Live will take place on May 27th, 2021. Sign up here to pre-register for the event!
Once again, DockerCon Live will be a free, online experience full of demos of products and innovation from Docker and our partners. You’ll get deep technical sessions from Docker experts, Docker Captains and luminaries from across the industry, along with a chance for the community to gather and connect with colleagues around the world.
Last year DockerCon Live 2020 was one of the largest events in the app dev industry– over 80,000 developers from 193 countries registered to hear over 50 sessions focused on best practices, real world techniques and how-to instruction for building containerized cloud-native solutions with Docker. Speakers joined from companies such as AWS, Google, Microsoft, Salesforce, Nginx, Snyk, Datadog, LaunchDarkly, among others.
For 2021, we are building on this format with a couple of new features including full day pre-conference technical workshops, additional content and more community activities. And there will be some surprises for everyone involved. If you Continue reading
This is the busiest time of the year for developers targeting AWS. Just over a week ago we announced the GA of Docker Compose for AWS, and this week we’re getting ready to virtually attend AWS re:Invent. re:Invent is the annual gathering of the entire AWS community and ecosystem to learn what’s new, get the latest tips and tricks, and connect with peers from around the world. Instead of the traditional week-long gathering of 60,000 attendees in Las Vegas, the event has pivoted to a flexible three-week online conference. This year the event is free, and anyone can participate on their own schedule. This blog post covers highlights of the event so Docker developers can get the most from re:Invent.
In the kickoff keynote by CEO Andy Jassy, AWS announced a number of new features for container developers, including a new capability, ECS Anywhere, which allows Amazon Elastic Container Service (ECS) to run on-prem and in the cloud to support hybrid computing workloads as well as the launch of AWS Proton, an end-to-end pipeline to deliver containerized and microservices applications. Separately, AWS also announced a new public Elastic Container Registry (ECR) and gallery today. We’re excited to see a Continue reading
Today, we are thrilled to announce that Canonical will distribute its free and commercial software through Docker Hub as a Docker Verified Publisher. Canonical and Docker will partner together to ensure that hardened free and commercial Ubuntu images will be available to all developer software supply chains for multi-cloud app development.
Canonical is the publisher of the Ubuntu OS, and a global provider of enterprise open source software, for all use cases from cloud to IoT. Canonical Ubuntu is one of the most popular Docker Official Images on Docker Hub, with over one billion images pulled. With Canonical as a Docker Verified Publisher, developers who pull Ubuntu images from Docker Hub can be confident they get the latest images backed by both Canonical and Docker.
Canonical is the latest publisher to choose Docker Hub for globally sharing their container images. With millions of users, Docker Hub is the world’s largest container registry, ensures Canonical can reach their developers regardless where they build and deploy their applications.
This partnership, which covers both free and commercial Canonical LTS images, so developers can confidently pull the latest images straight from the source without concern Continue reading
As we have been implementing rate limiting on Docker Hub for free anonymous and authenticated image pulls, we’ve heard a lot of questions from our users about how this will affect them. And we’ve also heard a number of statements that are inaccurate or misleading about the potential impacts of the change. We want to provide some answers here to help Docker users clearly understand the changes, quantify what is involved, and help developers choose the right Docker subscription for their needs.
First let’s look at the realities of what rate limiting looks like, and quantify what is still available for free to authenticated Docker users. Anyone can use a meaningful number of Docker Hub images for free. Anonymous, unauthenticated Docker users get 100 container pull requests per six hours. And when a user signs up for a free Docker ID, they get 2X the quantity of pulls. At 200 pulls per six hours, that is approximately 24,000 container image pulls per month per free Docker ID. This egress level is adequate for the bulk of the most common Docker Hub usage by developers. (Docker users can check their usage levels at any time through the command line. Docker developer Continue reading
The gradual enforcement of the Docker Hub progressive rate limiting enforcement on container image pulls for anonymous and free users began Monday, November 2nd. The next three hour enforcement window on Wednesday, November 4th from 9am to 12 noon Pacific time. During this window, the eventual final limit of 100 container pull requests per six hours for unauthenticated users and 200 for free users with Docker IDs will be enforced. After that window, the limit will rise to 2,500 container pull requests per six hours.
As we implement this policy, we are looking at the core technologies, platforms and tools used in app pipelines to ensure a transition that supports developers across their entire development lifecycle. We have been working with leading cloud platforms, CI/CD providers and other ISVs to ensure their customers and end users who use Docker have uninterrupted access to Docker Hub images. Among these partners are the major cloud hosting providers, CI/CD vendors such as CircleCI, and OSS entities such as Apache Software Foundation (ASF). You can find more information about programs on our Pricing Page as well as links to contact us for information about programs for ISVs and companies with more than 500 Continue reading
On August 13th, we announced the implementation of rate limiting for Docker container pulls for some users. Beginning November 2, Docker will begin phasing in limits of Docker container pull requests for anonymous and free authenticated users. The limits will be gradually reduced over a number of weeks until the final levels (where anonymous users are limited to 100 container pulls per six hours and free users limited to 200 container pulls per six hours) are reached. All paid Docker accounts (Pro, Team or Legacy subscribers) are exempt from rate limiting.
The rationale behind the phased implementation periods is to allow our anonymous and free tier users and integrators to see the places where anonymous CI/CD processes are pulling container images. This will allow Docker users to address the limitations in one of two ways: upgrade to an unlimited Docker Pro or Docker Team subscription, or adjust application pipelines to accommodate the container image request limits. After a lot of thought and discussion, we’ve decided on this gradual, phased increase over the upcoming weeks instead of an abrupt implementation of the policy. An up-do-date status update on rate limitations is available at https://www.docker.com/increase-rate-limits.

We are excited to be a gold sponsor of the inaugural SnykCon virtual conference, a free online event from Snyk taking place this week on October 21-22, 2020. The conference will look at best practices and technologies for integrating development and security teams, tools, and processes, with a specific nod of the secure use of containers, from images used as a starting point to apps shared with teams and the public.
At Docker, we know that security is vital to successful app development projects, and automating app security early in the development process ensures teams start with the right foundation and ship apps that have vulnerability scanning and remediation included by default. This year we announced a broad partnership with Snyk to incorporate their leading vulnerability scanning across the entire Docker app development lifecycle. At Snykcon, attendees will learn how to successfully incorporate security scanning into their entire Docker app delivery pipeline.
Some of the highlights from Docker at this event include:
