Docker unveiled the private beta of Docker Store, a marketplace for Docker-validated software, both free and commercial, at DockerCon 16 today.

Docker Store builds on the popularity of the Docker Hub for community content by providing an official marketplace.

“We launched Docker Hub for individuals to find and share containers,” said Docker CEO Ben Golub. “It’s now grown to 460,000 Dockerized apps. That’s exciting, but the containers there are of varying quality.”

Docker Hub launched in 2014 and has grown quickly: according to Docker, it’s grown 3,000 percent in two years.

The store provides enterprise users with commercially supported software from verified publishers that is packaged as Docker images and is easy to search. The store provides a publishing process that validates software quality, including security scanning, component inventory, the open-source license usage, and use of best practices in image construction.

Some of the enterprise software vendors participating in the initial beta launch of the Docker Store include Chef, CA Technologies, Puppet Labs, Datadog, Citrix, and New Relic.

Docker is adding people to the beta in batches over time.

Golub said today that Docker is promoting containers as an evolution to existing enterprise infrastructures.

“It’s an incremental revolution; you should find an approach that lets you grow over time,” he said. “It means starting small, imposing the least degree of change on the organization and allowing flexibility over time.”

Although it’s still common to use Docker containers for greenfield environments, increasingly, enterprises deploy Docker within their legacy infrastructures. They’re running containers alongside traditional on-premises applications, according to Golub.

“It took Amazon, Azure, and Google many years to become what they are,” he said, adding that he thinks it’s a fallacy that the only way to become agile is to lock an enterprise's applications to its infrastructure.

“We don’t believe in big revolutions,” Golub said. “Docker is disruptive, but adopting it shouldn’t disrupt your organization.”
