That container has everything that the application needs in order to be able to run. This includes an image of a Linux operating system. In this case Ubuntu 16 04.

To do that, we need to add a docker file. The cloud native JS project provides docker file templates as part of its open source projects. If we scroll down to where it refers to docker we can see this…
