Last valued at $2.1 billion at its Series C round three years ago, Palo Alto-based Docker divested its enterprise business to Mirantis as Johnston took the reins six years ago. That deal signaled a shift in strategic focus as competing containerization services — such as Google-led Kubernetes and RedHat’s OpenShift — had gained traction.
Subsequently, Docker “returned to its roots,” targeting developer tooling and container workflows rather than competing in enterprise infrastructure. This included new services spanning debugging, supply chain security, container testing, and a cloud-based container build service it launched last year.
