[Harbor](https://goharbor.io) is a CNCF-graduated open-source container registry. We use it to host custom built container images
from our projects. Key benefits for us are:

* Harbor automatically scans all container images with [Trivy](https://trivy.dev)
* fine grained access control allows Harbor to be used in a multi-team environment
* its extensive API allows easy adaption to custom needs, like retention policies
* support for image signing with [Cosign](https://github.com/SigStore/cosign)
