Addressing lingering concerns about container security, Docker has hardened its container-tech platform with a release that also adds several commercial features to ease enterprise deployments.
The San Francisco-based startup that sparked a revolution of sorts when it reintroduced Linux containers to enterprise IT delivered a number of advancements Thursday around container orchestration, networking and security with the release of Docker 1.10.
As Docker penetrates corporate data centers and clouds, the portfolio of new tools can be used to "build the kind of distributed applications that enterprises want to run in production," said David Messina, Docker's senior vice president of marketing.
Docker, the commercial entity behind the open-source software, follows a steady release cadence -- the software is usually updated every two months.
A key component of the latest release is Docker Compose, a much-simplified method for defining storage and networking topologies.
Compose is "one of the big things to come out of this release, in the realm of orchestration, being the model for taking multi-container distributed apps and allowing developers to define, cluster and schedule those apps," Messina told CRN.
Developers can define a distributed application, comprising a set of containers, in one simple file that controls the entire application life cycle, he said.
"Previously you would have to do a lot of command line work, manual configuration," Messina said. "Now it's much easier to get an application up and running all the way from development to production."
Aater Suleman, CEO of Flux7, a systems integrator based in Austin, Texas, that specializes in Docker and DevOps methodology, told CRN the latest release adds controls that will facilitate the onboarding of new users and pave a wider path to enterprise adoption.
But it's the upgrades around security that are especially vital and timely, he said.
