Q:

Docker stack to Kubernetes

I am quite familiar with Docker, but I have zero experience on Kubernetes. 
I have a Docker stack (multi-container) software that I can deploy in a Docker swarm cluster.  I was wondering if Kubernetes has something similar?  I don't need replicas, auto scaling and so on... I just need a group of containers working together with its dependencies and networks defined in single text file. 
I have searched and found a tool called kompose that translates the Docker stack file to Kubernetes syntax... However, it looks like the output is a list of *.yaml files, instead of a single file.  
So, I came to the conclusion that kubernetes does not have this exact functionality.. Am I missing something? 

A:

You can copy the content of the generated files into one file and separate them with ---. 
For instance, if you've got 3 Kubernetes files: service.yml, deployment.yml and configmap.yml, your file should look something like:
# content of service.yml
....
---
# content of deployment.yml
....
---
# content of configmap.yml
....

You would use the same kubectl commands to CRUD using this spec file.
