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…

Docker Hub Hits 5 Billion Pulls

Last week, the total number of image pulls from the Docker Hub Repository Service reached 5 billion. That’s an increase of 150% since just February. It’s pretty amazing for a three year old project. Docker Hub has become a part of the daily life of developers because it

Docker Security Scanning safeguards the container content lifecycle

written by Lily Guo, Toli Kuznets and Nandhini Santhanam Today we announced the general availability of Docker Security Scanning, formerly known as Project Nautilus. Available today as an add-on service to Docker Cloud private repositories and for Official Repositories located on Docker Hub, Security Scanning provides a detailed security profile of your Docker images for proactive risk management and to streamline software compliance. Docker Security Scanning conducts binary level scanning of your images before they are deployed, provides a detailed bill of materials (BOM) that lists out all the layers and components, continuously monitors for new vulnerabilities, and provides notifications when new vulnerabilities are found.

Announcing Docker Hub Classic

As we passed 2.5B pulls on Docker Hub recently, we were proud but we were also concerned. What if we’re simply using too much of the Internet for Docker? We certainly wouldn’t want to get in the way of streaming your favorite show (by the way, winter is coming). So, today we’re announcing Docker Hub Classic, an alternative way for Hub users to pull images from Docker Hub.
