Kubernetes Ecore Model

Ecore model for Kubernetes concepts. Part of the Nasdanika family of models.

Intended Use

• Creating models of Kubernetes solutions (deployments, services, etc.) and then generating Kubernetes manifests from them.
• Loading information about Kubernetes clusters into a model for subsequent reporting, analysis, and generation of recommendations.

Model Structure

The model is organized into the following packages:

• kubernetes (root) — Core concepts: Cluster, Namespace, Node, Resource (abstract base), KeyValuePair, LabelSelector, Taint
• workloads — Workload resources: Pod, Deployment, ReplicaSet, StatefulSet, DaemonSet, Job, CronJob, Container, PodTemplateSpec, Volume, ContainerPort, EnvVar, VolumeMount, ResourceRequirements
• networking — Networking resources: Service, ServicePort, Ingress, IngressRule, HTTPIngressPath
• storage — Storage resources: PersistentVolume, PersistentVolumeClaim, StorageClass
• configuration — Configuration resources: ConfigMap, Secret
