As conference-meme-run-wild Docker slowly chisels out a new vendor landscape, the technology continues its rapid evolution. Today, along with version 1.8 of the open platform, complete with sign and verification, the company announced a new installer for Mac OS X and Windows: Docker Toolbox.
In an official blogpost, Director of Product Management Ben Firshman writes that Toolbox promises to be “the fastest” way to get up and running with a Docker development environment. Acting as a sort of Swiss army knife for devs, it installs the Docker client, Machine and Compose (although this is currently limited to Mac), and allowing users to hit the ground running.
Within Docker 1.8, there have been a couple of notable tweaks to the software. Having announced back in June that the company is intending to spin out runC (a lightweight container runtime which infrastructure builders can utilise in their plumbing) as a standalone tool – Docker have taken further steps in this direction. System plumbing image signing has been implemented as an independent entity dubbed ‘Notary’, and volume plugins has been promoted from experimental status to stable release.
Security has been an ongoing concern both for those inside and outside of the Docker ecosystem. Back in May, container virtualization startup BanyanOps underlined these anxieties with their claim that over 30% of official images in the Docker Hub (the central repository for developers to pull and push container images) are riddled with “high priority security vulnerabilities.” In this latest release, confidence will hopefully be bolstered with the addition of Docker Content Trust, which allows you to verify the publisher of Docker images.
Along with these extras, there have been a number of fine tunings to to Engine, Compose, Swarm, Machine and Registry. If you’d like the full nitty gritty on Docker 1.8, check out the release notes for all the details, or if you’re ready to make the jump, head to installation instructions for Engine.
