  - Hewlett Packard Enterprise Distributions of Kubernetes
    The Hewlett Packard Enterprise distribution of Kubernetes, identified by the -hpe<number> suffix, incorporates the containerd runtime, which is required for all Kubernetes clusters created with HPE Ezmeral Runtime Enterprise version 5.5.0 and later.
  - Kubernetes Cluster Types and Compatibility
    An existing HPE Ezmeral Runtime Enterprise deployment that is upgraded from a previous release might contain Kubernetes clusters that use the containerd runtime and Kubernetes clusters that use the Docker runtime. All nodes in a Kubernetes cluster must use the same type of runtime.
  - Migrating Kubernetes Clusters from Docker to containerd
    This topic describes migrating legacy Kubernetes clusters from Docker container runtime to the the new Hewlett Packard Enterprise distribution of Kubernetes, which implements containerd runtime.

Kubernetes

The Kubernetes functionality in HPE Ezmeral Runtime Enterprise simplifies the creation and upgrade of virtual Kubernetes clusters that can be located on local physical hosts, virtual machines, or as cloud instances. The flexible multi-cluster and multi-tenant control plane allows you to deploy multiple open source Kubernetes clusters and/or manage cloud Kubernetes clusters (e.g. EKS) with no lock-in or modification to native Kubernetes required.

Data engineers, ML architects, and others can spin up containerized Kubernetes environments on scalable compute clusters with their choice of machine learning tools and frameworks for Big Data use cases. Some of the key features of Kubernetes on HPE Ezmeral Runtime Enterprise include:

HPE Ezmeral Runtime Enterprise can be installed on physical or virtual hosts located either locally (on-premises) or in a public cloud (see Controller, Gateway, and Worker Hosts).
Pre-integrated persistent container storage (see Tenant and Project Storage and Node Storage).
DataTaps and FS Mounts allow access to existing data sources, with no need to copy data back and forth. See About DataTaps and About FS Mounts.
All of the above features are bundled into multi-tenant, multi-cluster management for containerized environments using open-source Kubernetes orchestration to run a variety of database, analytics, AI/ML, app modernization, CI/CD pipeline, and other applications.
Big Data Kubernetes tenants: You can deploy KubeDirector applications or onboard Kubectl applications from the built-in Kubernetes Applications screen. See The Kubernetes Applications Screen, Deploying Applications (KubeDirector), and Onboarding Applications (Kubectl). Please also see Getting Started with General Kubernetes Functionality and AI and ML Project Workflow for a high-level overview of the general and AI/ML Kubernetes workflows, which also contains link to additional articles with detailed instructions for each step of the process.
Kubernetes Physical Architecture describes the physical structure (hosts, tenant, clusters, etc.) of Kubernetes within HPE Ezmeral Runtime Enterprise.
