Ruby Kubernetes Controller

CircleCI Gem Version RubyGems License

Ruby Kubernetes Controller is a Client-Side library which allows users to interact with core Kubernetes APIs natively from within their Ruby applications. This library is compatible with all leading Kubernetes Instances, including OpenShift Kubernetes, Azure Kubernetes Service, Amazon EKS, Google Kubernetes Service, IBM Kubernetes Service, and Rancher Orchestrated Kubernetes. This library also supports yaml ingestion for creating, patching, updating, or deleting existing Kubernetes types, including Pods, Services, Deployments, Endpoints, and Ingresses. Our documentation also contains complete examples for all operation types.
