How Docker Has Changed in the Last Four Years

AUSTIN — A lot has changed for Docker overc the last four years. At the Dockercon conference that got started today in Austin, Texas, Docker Inc. CEO Ben Golub highlighted the big changes and how it's the community that is pushing the technology forward.

Docker was created four years ago by Solomon Hykes and has grown into a global community in the years since. Golub said there are now over 14 million Docker hosts and some 900,000 Docker container applications. Over the last four years, there have been 12 billion image pulls from the Dockercon 17Docker Hub.

From just a single developer four years ago, Docker now has over 3,300 project contributors today. Perhaps most surprising about the volume of Docker contributors is how much comes from outside of Docker Inc.

Golub said Docker Inc currently has 320 employees. Looking at where contributions to Docker's open-source comes from, 41.5 percent come from individuals, which is the single largest source of contributions. Docker Inc is in second, at 40.6 percent of contributions.

Microsoft is also well represented at 7.7 percent of contributions, and IBM had 3.2 percent while Huawei and Red Hat both had 3.0 percent. All other corporate contributions combined added up to 10 percent of contributions.

Use Cases for Docker Continue to Grow

As further proof of Docker's growth, Golub noted Intuit is powering its Tax Day 2017 operation with a Docker container backend. Golub added that Intuit's docker lead is so confident in the deployment that he's actually at Dockercon today (on tax filing deadline day) instead of being tethered to an office system.

Golub noted Docker is now used in a wide variety of places, including helping to process billions of transactions per days. Docker is also used to monitor fire alarms by the military to keep soldiers away from landmines. And it's used by scientists to help cure diseases.

At its core, Docker has a very simple mission that it has been acting on for the last four years.

"Docker is about creating tools of mass innovation," Docker founder, CTO and Chief Product Officer Solomon Hykes said. "That's what we do every day."
