Does Kontain compete with Docker?

No! Kontain is integrated with Docker, and can run alongside Docker, as well as other container runtimes, even on the same Kubernetes node. We’ve preserved all the great capabilities of Docker, even as we have replaced the bloated, inefficient, and non-secure runtime environment of traditional containers. We built Kontain for people who love containers and love Docker, but want to use them in a way that is vastly more secure, efficient, and speedy.
