1. Summary:

Nephio Project uses combination of Prow with additional help of GitHub Actions as a CI/CD and GitHub management solution.

Prow is a Kubernetes based CI/CD, its main features:

• Job execution for testing, batch processing, artifact publishing
• GitHub events are used to trigger post-PR-merge (postsubmit) jobs and on-PR-update (presubmit) jobs
• Support for multiple execution platforms and source code review sites
• Pluggable GitHub bot automation that implements /foo style commands and enforces configured policies/processes
• GitHub merge automation with batch testing logic
• Front end for viewing jobs, merge queue status, dynamically generated help information
• Config-as-a-code with automagically applying changes.
• Automatic GitHub org/repo administration configured in source control.
• All benefits of running on Kubernetes - replication, load balancing, rolling updates, addons like Istio.
• JSON structured logs.
• Prometheus metrics.

What do we do with it:

• Code checking for syntax, common errors, security problems
• Licensing compliance scanning
• Artifacts building and delivery
• Testing environment provisioning
• Keeping GitHub policies applied
