Docker is a virtualization technology which is different from a "virtual machine". See an overview like: https://www.infoworld.com/article/3204171/what-is-docker-docker-containers-explained.html
The zCX engine/host operating may be based on Ubuntu Linux; it isn't technically correct to say the the "Linux *kernel* is Ubuntu". Also, it doesn't matter too much that the Docker engine/host operating system is a particular Linux distribution. Docker images derived from different distributions can run in it. To confuse things, the zCX engine/host linux operating system runs inside a z/OS address space using virtual machine technology.
