Feature Overview (aka. Goal Summary)  

Workload identity is a key part of the zero-trust model. The SPIRE project aims to simplify the management and distribution of workload identities in the form of cryptographically verifiable identity documents. There is an increasing interest and uptake in this space within the Cloud native ecosystem.  The goal is to give customers a practical and scalable way to establish trust in a multi-cloud, multi-platform environment. It will strengthen OpenShift’s security capabilities and value-add as organizations harden their security policies.

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.

Use Cases (Optional):

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

<To be added> 

Questions to Answer (Optional):

From Alec Henninger There is just one "user" type for all service accounts/workloads or human users in Kessel. This is so that there is no special casing of access set up – an identity is an identity. A thing gets permissions or it doesn't.  

However, all identities are also namespaced by their "issuer".  So for example SPIFFE identities could be prefixed with a certain SPIRE issuer. That way they can be assigned permissions / permissions checked like any other user.
