DockerCon brings industry leaders and experts of the container world to one event where they share their knowledge, experience and guidance. This year is no different. For the next few weeks, we’re going to highlight a few of our amazing speakers and the talks they will be leading. In this third highlight, we have several speakers who will be sharing their real world Docker use cases and learnings.  These are the folks who have already put things in place and are here to share and inspire. Interested in transforming legacy applications? Or maybe large scale data analytics is your focus. Maybe…

In case you missed our announcement a couple of weeks ago, Docker Hub now has an improved user experience for finding, storing and sharing Docker container images. Our second most popular blog of 2018 gives users a preview of the new Docker Hub. Read on to learn more about what’s new on 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 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…

In the first blog post about the experimental Docker Application Packages, Gareth showed how our new open-source docker-app can be used to augment Compose files by adding metadata and separate settings. Now that you know how to create an Application Package, how do you share it? Using a Docker registry solution like Docker Hub or Docker Enterprise of course! Let’s look at an example that works with the latest release of docker-app. Here’s a simple single-file format Application Package with the filename hello.dockerapp: # This section contains your application metadata. version: 0.1.0 name: hello description: “A simple HTTP echo server” maintainers: – name: Chris Crone…

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…

[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…

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…
