Introducing the New Docker Hub

Today, we’re excited to announce that Docker Store and Docker Cloud are now part of Docker Hub, providing a single experience for finding, storing and sharing container images. This means that: Docker Certified and Verified Publisher Images are now available for discovery and download on Docker Hub Docker Hub has a new user experience   Millions of individual users and more than a hundred thousand organizations use Docker Hub, Store and Cloud for their container content needs. We’ve designed this Docker Hub update to bring together the features that users of each product know and love the most, while addressing known Docker Hub requests around ease of use, repository and team management. Here’s what’s new: Repositories View recently pushed tags and automated builds on your repository page Pagination added to repository tags Improved repository filtering when logged in on the Continue reading…

Docker App and CNAB

Docker App is a new tool we spoke briefly about back at DockerCon US 2018. We’ve been working on `docker-app` to make container applications simpler to share and easier to manage across different teams and between different environments, and we open sourced it so you can already download Docker App from GitHub at https://github.com/docker/app. In talking to others about problems they’ve experienced sharing and collaborating on the broad area we call “applications” we came to a realisation: it’s a more general problem that others have been working on too. That’s why we’re happy to collaborate with Microsoft on the new Cloud Native Application Bundle (CNAB) specification. Today’s cloud native applications typically use different technologies, each with their own toolchain. Maybe you’re using ARM templates and Helm charts, or CloudFormation and Compose, or Terraform and Ansible. There is no single solution Continue reading…

Using Your Own Private Registry with Docker Enterprise Edition

One of the things that makes Docker really cool, particularly compared to using virtual machines, is how easy it is to move around Docker images. If you’ve already been using Docker, you’ve almost certainly pulled images from Docker Hub. Docker Hub is Docker’s cloud-based registry service and has tens of thousands of Docker images to choose from. If you’re developing your own software and creating your own Docker images though, you’ll want your own private Docker registry. This is particularly true if you have images with proprietary licenses, or if you have a complex continuous integration (CI) process for your build system. Docker Enterprise Edition includes Docker Trusted Registry (DTR), a highly available registry with secure image management capabilities which was built to run either inside of your own data center or on your own cloud-based infrastructure. In the next few weeks, we’ll Continue reading…

Multi-arch All The Things

[This post was written by Phil Estes and Michael Friis.] True multi-platform workload portability has long been the holy grail of enterprise computing. All kinds of virtualization strategies have been used over the years to approximate this dream to varying levels of acceptable performance or usability. On the one hand, virtual machines and hardware virtualization are flexible enough that you can mix and match operating systems (and even CPU architectures) on the same host—but they come with a lot of overhead. However, language-based virtual runtimes don’t have packaging formats that encapsulate all system-level app dependencies, and that makes them unsuitable for general-purpose deployment and configuration management. Docker came along as a unique type of virtualization that only virtualizes the operating system for container processes. Docker uses existing Linux kernel features to offer isolation characteristics that are similar to what is available Continue reading…

Docker Official Images are now Multi-platform

This past week, Docker rolled out a big update to our Official Images to make them multi-platform aware. Now, when you run docker run hello-world, Docker CE and EE will pull and run the correct hello-world image whether that’s for x86-64 Linux, Windows, ARM, IBM Z mainframes or any other system where Docker runs. With Docker rapidly adding support for additional operating systems (like Windows) and CPU architectures (like IBM Z) this is an important UX improvement. Docker Official Images are a curated set of container images that include: Base operating system images like Ubuntu, BusyBox and Debian Ready-to-use build and runtime images for popular programming languages like Go, Python and Java Easy-to-use images for data stores such as PostgreSQL, Neo4j and Redis Pre-packaged software images to run WordPress, Ghost and Redmine and many other popular open source projects The official images have always been available for x86-64 Linux.

Docker Announces Expansion To China Through Commercial Partnership with Alibaba Cloud

The containerization movement fueled by Docker has extended across all geographic boundaries since the very beginning. Some of Docker’s earliest success stories were from Chinese based, web-scale companies running Docker in production before Docker had released its 1.0 version. Additionally, through the grass roots efforts of the development community, we have thriving Docker Meetups in 20 of China’s largest cities. This is a testament to the innovative spirit within the Chinese developer community because the ability to deliver great community content from Docker Hub has been highly constrained. That is why a partnership with China’s largest public cloud provider is so significant. Docker, in concert with Alibaba Cloud, is going to deliver a China-based instance of Docker Hub to ensure optimal access and performance to the thousands of Dockerized images that will serve as the foundation of a new generation Continue reading…
