This document discusses Docker Inc.'s efforts to establish an open platform for containers through open source and open standards. It summarizes Docker's work on projects like runc, OCI, and containerd that established the building blocks for container technologies. It also notes Docker's rapid growth from 2013 to 2016 and transition from focusing initially on developers to later prioritizing orchestration and production usage through projects like Docker Swarm. The document evaluates how Docker's open source strategy helped establish it as the dominant player in the container space initially before other companies began competing in the container platform market.
