Defining Multiple Objects in the Same YAML file
Learn how to combine all the services, API's and replicaSets into one YAML file.
We'll cover the following
Combining multiple YAML files into one file#
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:
The output of the latter command is as follows.
The two ReplicaSets and the two Services were created, and we can rejoice in replacing four files with one.
Finally, to be on the safe side, we’ll also double-check that the stack API is up-and-running and accessible.
The response is 200 indicating that everything works as expected.
