5.6 Reference
- HPE Ezmeral Runtime Enterprise 5.6
- Software Versions
- Kubernetes Bundles
  Kubernetes Bundles are software packages that can contain software to support newer Kubernetes versions, updated add-ons, and software fixes. Kubernetes Bundles enable you to update your deployment without requiring you to upgrade to a newer version of HPE Ezmeral Runtime Enterprise.

  - Controller, Gateway, and Worker Hosts
  - Gateway Hosts
    Gateway hosts run the HAproxy service and are part of the HPE Ezmeral Runtime Enterprise control plane. You can access the web UI of a HPE Ezmeral Runtime Enterprise deployment through any Gateway host. For high availability and load balancing, configure multiple Gateway hosts.
  - HAproxy service
    The HAproxy service enables load balancing and SSL termination. After the Gateway hosts are set up, the HPE Ezmeral Runtime Enterprise Controller automatically starts using the Gateway proxy set for container port mappings.
  - Networks and Subnets
    HPE Ezmeral Runtime Enterprise hosts are connected through an external switch that is accessible to the network that your organization manages. Internally within HPE Ezmeral Runtime Enterprise, Kubernetes pods communicate through a private nonroutable virtual network that is not visible to the host network.
