      Feature Overview (aka. Goal Summary)  

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

      Some Kubernetes clusters do not have direct Internet access and rely solely on proxies for communication, so OLM v1 needs to support proxies to enable this communication.

      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.

      Some Kubernetes clusters do not have direct Internet access and rely solely on proxies for communication. This may be done for isolation, testing or to enhance security and minimise vulnerabilities. This is a fully supported configuration in OpenShift, with origin tests designed to validate functionality in proxy-based environments. Supporting proxies is essential to ensure your solution operates reliably within these secure and compliant setups.
      To address this need, we have two key challenges to solve:

      1. Enable catalogd and the operator-controller to work with OpenShift proxy configurations. 
      2. Implement a solution to pass the proxy configuration for the solutions managed by OLM so that they work well with the proxy.

      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.

      1. Enable catalogd and the operator-controller to work with OpenShift proxy configurations. 
      2. Implement a solution to pass the proxy configuration for the solutions managed by OLM so that they work well with the proxy.
      3. Trusted CA support

       

      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.

      Out of Scope

      High-level list of items that are out of scope.  Initial completion during Refinement status.

      • Proxy support for operator-controller when communicating with catalogd.
      • Adding code to support proxies upstream (the environment variable mechanism can be used).
      • Support for CSV-defined proxies.
      • oc-mirror support (which should already be there)

      Background

      Provide any additional context is needed to frame the feature.  Initial completion during Refinement status.

      OpenShift’s centralized proxy control via the proxies.config.openshift.io (a.k.a. proxy.config.openshift.io) resource makes managing proxies across a cluster easier. At the same time, vanilla Kubernetes requires a manual and decentralized proxy configuration, making it more complex to manage, especially in large clusters. There is no native Kubernetes solution that can adequately address the need for centralized proxy management.

      Kubernetes lacks a built-in unified API like OpenShift’s proxies.config.openshift.io, which can streamline proxy configuration and management across any Kubernetes vendor. Consequently, Kubernetes requires more manual work to ensure the proxy configuration is consistent across the cluster, and this complexity increases with the scale of the environment. As such, vanilla Kubernetes does not provide a solution that can natively address proxy configuration across all clusters and vendors without relying on external tools or complex manual processes (such as that devised by OpenShift).

      Customer Considerations

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

      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.
