TL;DR – Last Week’s Container News (4/14/17–4/21/17)

LinuxKit & Moby Project

At DockerCon 17 last week, Docker Inc. debuted two new efforts: LinuxKit and Moby Project.

LinuxKit incorporates the Docker-built Linux subsystem (the tooling behind Docker for Mac and Docker for Windows), and will work with, “desktop, server, internet of things (IoT), mainframe, Intel, ARM, as well as bare metal and virtualized deployments,” according to an eWeek article. Meanwhile, the Moby Project contains a “library of over 80 components including all the vital parts needed for a container platform,” and, “builds on top of LinuxKit… to help a developer rapidly build and deploy a container platform.”

A separate analysis by eWeek describes the Moby Project as the next step in the “democratization” of Docker as a technology standard. (Democratization began with the open sourcing of “key run-time component, containerd.” The Moby Project, “takes care of the rest,” according to the article.)

“All of the core pieces of Docker are released as open source technology under the project … with a framework for assembling them and a reference implementation. Users and vendors can create their own container systems from all or some of the pieces.”

New Offerings, New Features: Bitbucket Piplines Connects to Docker, IBM Bluemix Container Service, Docker Service to Modernize Apps, RancherOS

BITBUCKET PIPELINES CONNECTS TO DOCKER – Bitbucket Pipelines – used for chaining together tools in a continuous integration environment – was recently updated to incorporate Docker containers, according to coverage by The New Stack. The update means users can leverage both user-built containers and service containers within their “assembly line of code.” Users can host, “up to three services within their Bitbucket Pipeline test environment,” with task chains that, “quickly spin up dependency services, like MySQL, Redis or any of the other services presented as containers in the Docker Hub.” Check out The New Stack’s complete coverage here: BITBUCKET PIPELINES CONNECTS TO DOCKER

IBM BLUEMIX CONTAINER SERVICE – IBM recently announced the new IBM Bluemix Container Service, which incorporates Kubernetes and the Docker Engine on IBM’s “Bluemix” cloud platform. IBM’s website calls it, “a highly secure, native Kubernetes experience for rapidly building cognitive apps.” The Bluemix Container Service, “automatically provisions, updates and monitors the containers that developers use to create apps, helping them to more easily build cognitive applications,” according to coverage by The New Stack.

DOCKER SERVICE TO MODERNIZE LEGACY APPS – At DockerCon last week, Docker Inc. announced a new professional services offering to “modernize traditional applications,” according to coverage by eWeek. The offering includes professional services, plus Docker Enterprise Edition and hybrid cloud infrastructure provided by Docker partners. According to the eWeek article, Docker Chief Operating Officer Scott Johnston claims their service can “take a typical legacy application, containerize it and put it under Docker EE management on modern infrastructure” in approximately five days. They do this without having to go “back to source code” or rewrite the application. Follow the link to read more: DOCKER PROFESSIONAL SERVICES

RANCHEROS – Rancher Labs recently announced the general availability of RancherOS, a lightweight operating system that claims to offer, “reduced boot time while enhancing security by cutting down on the number of components that could be exploited,” according to an article by The New Stack. The OS features “a lot of overlap functionality with Docker” and supports “a variety of platforms, including Amazon EC2, bare metal, KVM and OpenStack.” Follow the link for The New Stack’s complete coverage: RANCHEROS

Analysis & Op-Ed: Future of Kubernetes Ecosystem, Getting Cloud Platforms to Work Together, Security Better in the Cloud

FUTURE OF KUBERNETES – The New Stack recently shared a podcast “exploring the future of the Kubernetes ecosystem.” The podcast features Google developer advocate Kelsey Hightower, and Deis Software engineer Michelle Noorali, discussing, “managing long-term cluster security, building one’s own toolkit for working with Kubernetes, and operators.” Follow the link to hear the complete podcast: FUTURE OF KUBERNETES

GETTING CLOUD PLATFORMS TO WORK TOGETHER – The New Stack recently shared an analysis on “living in a multi-cloud world.” According to the article, enterprises by necessity grapple with multiple platforms, each of which are designed “from a particular architectural perspective,” or for specific use cases. The trick is not looking for “one platform to rule them all,” but instead finding a way to get different platforms to work together. The article covers “Why BOSH Makes Sense for a Multi-Platform World,” how Kubo, (“an open source project that uses BOSH to manage Kubernetes clusters”), is “bringing multi-cloud to Kubernetes,” and how the Open Service Broker API can “enable platforms and back end services to work together.” Follow the link for the complete analysis: MULTI-CLOUD WORLD

SECURITY BETTER IN THE CLOUD – Email delivery service SparkPost recently shared an editorial on, “why security is better in the cloud,” via VentureBeat. The article outlines drawbacks to securing email on-prem, including, “physical aspects like secure siting,” “complex issues such as network defense and isolation,” and, “continuous risk assessment, threat monitoring, and mitigation,” all of which require, “significant investment in highly skilled staff working around the clock.” By contrast, the article calls modern cloud architectures, “secure by design,” with, “policy-based separation among infrastructural components [that] ensure a level of compartmentalization that few traditional data center platforms can offer.” Follow the link to read the complete editorial: CLOUD SECURITY IS BETTER

Tutorials & How-Tos: GPUs in Kubernetes, DigitalOcean Kubernetes, Dockerizing Your First App, Triton Custom Domains

GPUS IN KUBERNETES – Enablement of GPUs in Kubernetes just got a lot easier, according to an article on Medium. The process, which used to involve five steps and take at least 30-45 minutes, now involves just a single step (“deploy a normal K8s cluster with Juju”). This is thanks to Canonical’s team, which has “productized GPU integration,” according to the article. The article provides a walkthrough if you want to try it yourself. Check it out: GPUS KUBERNETES TUTORIAL

DIGITALOCEAN KUBERNETES – The New Stack recently shared a tutorial on “configuring a Kubernetes DevTest Cluster in DigitalOcean.” (DigitalOcean is “an affordable cloud computing platform for developers” and “one of the fastest growing public cloud services companies,” according to the article). The tutorial outlines steps to configure a multi-node Kubernetes cluster in DigitalOcean, including:

  • Setting up the Environment
  • Configuring the Kubernetes Master & Kubernetes Nodes
  • Deploying an Application & Configuring the Load Balancer
  • Accessing the App & Adding Additional Nodes

DOCKERIZE YOUR FIRST APP – Joyent recently shared training for “Dockerizing your first application.” This is a great intro to Docker, Docker Hub, and Triton’s public cloud, and will walk you through dockerizing the popular 2048 game and deploying both locally and to the cloud. Follow the link for this great introduction to several powerful tools: DOCKERIZE FIRST APP

TRITON CUSTOM DOMAINS – Triton users can assign custom DNS names to their applications – with the help of a recent tutorial by Joyent. The tutorial shows users how to associate a vanity domain with existing canonical name records (CNAMEs). These vanity domains are more memorable and meaningful than the DNS name assigned by default. Follow the link to view the complete tutorial, and get started assigning your own vanity domains: TRITON VANITY DOMAINS

General News / Announcements: Oracle Buys Wercker, Docker’s Growing Business

ORACLE BUYS WERCKER – Oracle will soon acquire Wercker, a Dutch startup that offers a “container-centric platform,” to help, “automate the development of applications and microservices,” according to coverage by VentureBeat. According to a statement by Oracle, Oracle’s Cloud should benefit from Wercker’s container lifecycle management. An FAQ document by Oracle claims Wercker, “will be integrated into Oracle’s existing developer-focused tools and services.” Follow the link for VentureBeat’s complete coverage: ORACLE BUYS WERCKER

DOCKER’S GROWING BUSINESS – In a recent video interview with eWeek, Docker CEO Ben Golub gave the rundown on Docker Inc.’s business model and progress. According to the interview, Docker has seen “a great ramp in terms of the number of customers,” as well as usage expansion among current customers (“on average by five times within six months”).
