Review of Installer supports bootstrap in place of a Single Node OpenShift using live iso


    • Installer for Single-node Deployments
    • False
    • False
    • Done
    • OCPPLAN-5819 - Single Node OpenShift - "Production Edge" - 4.8 - dev-preview
    • Undefined
    • Telco 5G RAN

      Epic Goal

      • Support deploying single-node OpenShift configurations for production use in edge computing use cases.

      Why is this important?

      • Some bare metal edge customers, especially in the telco market, want to use kubernetes at physically remote sites with minimal hardware.


      1. As a deployer, I can use the installer to configure a single-node OpenShift cluster.
      2. As an operator author, I can use an API within the cluster to detect the single-node configuration and adjust my operand accordingly.

      Acceptance Criteria

      • CI - MUST be running successfully with tests automated
      • Release Technical Enablement - Provide necessary release enablement details and documents.

      Dependencies (internal and external)

      2. https://github.com/openshift/enhancements/pull/560
      3. OCP Single Node Production Edge Profile

      Open questions::

      1. What should the input for specifying a single-node cluster look like?
      2. What should the API for discovering that a cluster is single-node look like?
