This package can generate a configuration for a Kubernetes resource.
It provides classes to define the property values of several types of resources used in Kubernetes, like labels, containers, and pods.
The package can generate a configuration file in YAML format for a pod previously defined to be associated with a container with given labels. Innovation Award

Kubernetes is a system to manage containers used in many cloud hosting systems.
Containers are helpful for managing and running applications that can run in an isolated way, including those that implement PHP-based Web applications.
This package provides a simplified way to generate configuration files to use with Kubernetes containers from given parameters.

// Finally fill the Pod values

->serviceAccount('pod-service-account')
->toYaml();
Use toYaml() method to generate a YAML representation of the Kubernetes resource.
