      Feature Overview (aka. Goal Summary)  

      An elevator pitch (value statement) that describes the Feature in a clear, concise way.  Complete during New status.

      OpenShift currently documents manual shutdown & restart procedures. This includes providing guidance on executing etc-backups and warnings about the possibility of cert exploration during the "shutdown" which may require manual intervention during startup.

       

      This feature is to create an OCP-native option for a cluster-admin to trigger a proper shutdown of the whole cluster (workers and control plane nodes)

      Goals (aka. expected user outcomes)

      The observable functionality that the user now has as a result of receiving this feature. Include the anticipated primary user type/persona and which existing features, if any, will be expanded. Complete during New status.

      This feature is to create an OCP-native option for a cluster-admin to trigger a proper shutdown of the whole cluster (workers and control plane nodes)

      Requirements (aka. Acceptance Criteria):

      A list of specific needs or objectives that a feature must deliver in order to be considered complete.  Be sure to include nonfunctional requirements such as security, reliability, performance, maintainability, scalability, usability, etc.  Initial completion during Refinement status.

      • The logic should provide configurable parameters allowing a cluster-admin to setup thresholds (e.g. how much time to wait for a worker to stop before raising errors or alarms)
      • The logic should shutdown all non-control-plane nodes first and then proceed with the control plane nodes

       

      Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed.  Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.

      Deployment considerations List applicable specific needs (N/A = not applicable)
      Self-managed, managed, or both self-managed
      Classic (standalone cluster) yes
      Hosted control planes no
      Multi node, Compact (three node), or Single node (SNO), or all Multi-node & compact
      Connected / Restricted Network both
      Architectures, e.g. x86_x64, ARM (aarch64), IBM Power (ppc64le), and IBM Z (s390x) all
      Operator compatibility ??
      Backport needed (list applicable versions) n/a
      UI need (e.g. OpenShift Console, dynamic plugin, OCM) ??
      Other (please specify)  

      Use Cases (Optional):

      Include use case diagrams, main success scenarios, alternative flow scenarios.  Initial completion during Refinement status.

      Questions to Answer (Optional):

      Include a list of refinement / architectural questions that may need to be answered before coding can begin.  Initial completion during Refinement status.

      Customer Considerations

      Provide any additional customer-specific considerations that must be made when designing and delivering the Feature.  Initial completion during Refinement status.

      <your text here>

      Documentation Considerations

      Provide information that needs to be considered and planned so that documentation will meet customer needs.  If the feature extends existing functionality, provide a link to its current documentation. Initial completion during Refinement status.

      Interoperability Considerations

      Which other projects, including ROSA/OSD/ARO, and versions in our portfolio does this feature impact?  What interoperability test scenarios should be factored by the layered products?  Initial completion during Refinement status.
