FluxCD

Highlights @Fiachra Corcoran .

The integration of the default FluxCD controllers into the Nephio management cluster offers an alternative GitOps provider to the end user.

This enables a centralized GitOps approach for deploying workloads to remote clusters, thus reducing the load on potentially resource constrained edge sites by removing the need to run you git-ops reconciler at the edge. See Centralized FluxCD Workload Cluster Deployment for more details.

Technical Debt

Porch

• Certificate renewal on webhooks

• Checks for binary files in kpt packages

• Fix synchronization on concurrent Create/update/Delete operations

• Make maximum request size configurable

• Refactor cache into a single package

• Remove unused Function CRD

• Fix exponential increase in package approval time

• Support private authenticated registries for upstream packages

• Allow configuration of interval of background periodic synchronization job

• Allow TLS configuration of function-runner images

• Enable rendering of packages > 4MB in the kpt function runner

• Refactor the Porch code to improve the structure of the Porch engine and task handling

• Refactor mutex handling on cache refreshing to avoid deadlocks

• Prevent proposing and approval of packages if the kpt pipeline of the package fails to render

• Fix modify event handling on package revisions

• Refactor mutexes to allow concurrent reads on package revisions

• Many small bugs fixed
