IMO docker did an amazing paradigm shift of many apps from heavy weight VMs to Micro Services,lot in CI/CD etc .. But all of them dnt make sense without an orchestration platform . Just like how a standalone VM does not make any commercial sense. This has been a question for long time about their revenue model. I guess they did try with compose , swarm , etc but the space was already taken by Kubernetes . I dnt know docker as company would be profitable ..
