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. 

Goals (aka. expected user outcomes)

Support with RHACM for Seamlessly scaling SPIRE deployments

Requirements (aka. Acceptance Criteria):

Activity	Dependency	Contacts
Enable nested spire configuration to support hub and spoke model of deployment.	IBM Research team reviews and recommendations	IBM Research team
RHACM templates are required to support deployment of nested Spire topology.	RHACM team support to develop templates	Christian Stark Sho Weimer
BYO External CA -  integration helps in cases where external CA chain of trust is used for workload communications.	Reviews by Auth experts in Control Plane team, Certificate management team	David Eads Seth Jennings
