Kubernetes Operators

Kubernetes Operator, Kubernetes CRD

One of the key reasons for Kubernetes’s popularity is its extendibility. Kubernetes API extensions (commonly referred as Operators) extend Kubernetes API to manage third-party software as native Kubernetes objects. There are 400+ GitHub repositories with Operator implementations for middleware like databases, queues, loggers, etc. Kubernetes Operators form foundation for Platform-as-Code experience. 

API wrapper Vs Operators

API wrappers: Traditional method of creating platform abstractions

Kubernetes Operators

  • Disparate interfaces to learn / manage.
  • Hard to leverage tools and features developed for native interface with new abstractions.

Operators (API extensions): New method of creating platform abstractions

Kubernetes Operators

  • One common interface to use for native and newly added abstractions.
  • Can easily leverage tools (e.g. Helm) or features (e.g. auditing) for native interface with new abstractions.

What is Platform-as-Code ?

Platform as Code is the process of aggregating multiple Kubernetes Operators for the purpose of creating and managing platforms declaratively using native Kubernetes interfaces (kubectl & Kubernetes YAML), rather than ad-hoc scripts or new CLIs. 


  • Assembly of multiple Kubernetes API extensions (aka Operators)
  • Discovery of custom resources introduced by Operators 

Key tenets

  • No new file formats: Leverage Kubernetes native input mechanisms, e.g. Use of annotations, configmaps
  • No new CLIs: Leverage existing CLIs (kubectl, helm)

Introducing Platform-as-Code: New Cloud Computing Model


Platform as Code

As-Code’ systems are those that provide declarative model for defining and managing elements in your application stack. Pioneered by Infrastructure-as-Code systems like Terraform, the ‘Infrastructure-as-Code’ approach provides repeatability, shareability, versioning in provisioning infrastructure elements. On the similar lines, the 'Platform-as-Code' approach provides declarative model for defining, provisioning and managing platform elements through its lifecycle. 

Operational Efficiency with Platform-as-Code


Composable, Repeatable and Shareable Application Platforms as Code

  • Compose your application platforms using enterprise-ready Kubernetes API extensions (Operators). 
  • Repeatably create application platforms as Code with Kubernetes YAML definition. 
  • Share platform definition YAMLs among team members.
