Moby Summit LA alongside Open Source Summit North America

By , , , , , , , ,

Since the Moby Project introduction at DockerCon 2017 in Austin last April, the Moby Community has been hard at work to further define the Moby project, improve its components (runC, containerd, LinuxKit, InfraKit, SwarmKit, Libnetwork and Notary) and fine processes and clear communication channels. All project maintainers are developing these aspects in the open with the support of the community. Contributors are getting involved on GitHub, giving feedback on the Moby Project Discourse forum and asking questions on Slack. Special Interest Groups (SIGs) for the Moby Project components have been formed based on the Kubernetes model for Open Source collaboration. These SIGs ensure a high level of transparency and synchronization between project maintainers and a community of heterogeneous contributors. In addition to these online channels and meetings, the Moby community hosts regular meetups and summits. Check out the videos and slides from the last Continue reading…

Securing the AtSea App with Docker Secrets

By , , , ,

Passing application configuration information as environmental variables was once considered best practice in 12 factor applications. However, this practice can expose information in logs, can be difficult to track how and when information is exposed, third party applications can access this information. Instead of environmental variables, Docker implements secrets to manage configuration and confidential information. Secrets are a way to keep information such as passwords and credentials secure in a Docker CE or EE with swarm mode. Docker manages secrets and securely transmits it to only those nodes in the swarm that need access to it. Secrets are encrypted during transit and at rest in a Docker swarm. A secret is only accessible to those services which have been granted explicit access to it, and only while those service tasks are running. The AtSea Shop is an example storefront application that can be deployed Continue reading…

Docker for the SysAdmin Webinar Q&A

By , , , , , ,

On June 27th I presented a webinar on “Docker for the SysAdmin”.  The webinar was driven by a common scenario I’m seeing: A sysadmin is sitting at her desk minding her own business when a developer walks in and says “here’s the the new app, it’s in a Docker image. Please deploy it ASAP”. This session is designed to help provides some guidance on how sysadmins should think about managing Dockerized applications in production. In any case, I was a bit long-winded (as usual), and didn’t have time to answer all the Q&A during the webinar (and there were quite a few). So, as promised, here are all the questions from that session, along with my answers.  If you need more info, hit me up on Twitter: @mikegcoleman ———— Q: I am planning an application deployment and want to use Docker.

Multi-Stage Builds

By , ,

This is part of a series of articles describing how the AtSea Shop application was built using enterprise development tools and Docker. In the previous post, I introduced the AtSea application and how I developed a REST application with the Eclipse IDE and Docker. Multi-stage builds, a Docker feature introduced in Docker 17.06 CE, let you orchestrate a complex build in a single Dockerfile. Before multi-stage build, Docker users would use a script to compile the applications on the host machine, then use Dockerfiles to build the images. The AtSea application is the perfect use case for a multi-stage build because: it uses node.js to compile the ReactJs app into storefront it uses Spring Boot and Maven to make a standalone jar file it is deployed to a standalone JDK container the storefront is then included in the jar Let’s look at the Dockerfile. The react-app is Continue reading…

Announcing Docker 17.06 Community Edition (CE)

By

Today we released Docker CE 17.06  with new features, improvements, and bug fixes. Docker CE 17.06 is the first Docker version built entirely on the Moby Project, which we announced in April at DockerCon. You can see the complete list of changes in the changelog, but let’s take a look at some of the new features. We also created a video version of this post here: Multi-stage builds The biggest feature in 17.06 CE is that multi-stage builds, announced in April at DockerCon, have come to the stable release. Multi-stage builds allow you to build cleaner, smaller Docker images using a single Dockerfile. Multi-stage builds work by building intermediate images that produce an output. That way you can compile code in an intermediate image and use only the output in the final image. So for instance, Java developers commonly use Apache Maven to compile Continue reading…

Docker at Nutanix .NEXT Conference – Visit us at Booth #S11

By , , ,

Today marks the start of Nutanix .NEXT Conference in Washington, D.C., the annual conference for Nutanix customers and partners. One of the major themes of the conference is hybrid cloud, and Docker will be there to demonstrate how Docker Enterprise Edition delivers application portability across different infrastructure platforms through a complete enterprise-ready Container as a Service (CaaS) solution for IT. Docker and Nutanix will also be highlighting the Nutanix Docker Volume Plug-in (DVP), a Docker Certified Plugin available in the Docker Store. This plugin connects Docker containers to enterprise-grade persistent storage from Nutanix even as the container is powered on, powered off, or moved to a new host. As part of the certification process, Docker and Nutanix validate that the plugin is built with Docker recommended best practices and passes an additional suite of API compliance testing and vulnerability scanning.

Moby Summit June 2017 Recap

By , , , ,

On June 19 2017, 90 members of the Moby community gathered at Docker headquarter in San Francisco for the second Moby Summit.  This was an opportunity for the community to discuss the progress and future of the Moby project, two months after it was announced. We started the day with an introduction by Solomon Hykes, and a look at the website redesign: the Moby project website now has a blog, an event calendar, a list of projects, and a community page with links to various community resources. The website code is open source, issues and PRs to make it better are welcome. Then each team gave an update on their progress: Linuxkit, containerd, InfraKit, SwarmKit and LibNetwork, as well as the three new Moby Special Interest Groups, Linuxkit Security, Security Scanning & Notary and Orchestration Security. All these talks have been Continue reading…
