All the YAML files defined in the previous lesson for pods, services, and API work together. But having four YAML definitions is confusing. It would get even more confusing later on since we are going to add more objects to the stack. Things would be much simpler and easier if we would move all the objects we created thus far into a single YAML definition. Fortunately, that is very easy to accomplish.

Let’s take a look at yet another YAML file go-demo-2.yml in the code playground at the end of the lesson. It is the same as the contents of the previous four YAML files combined. The only difference is that each object definition is separated by three dashes (---).

We will create the objects defined in the go-demo-2.yml in this lesson:
