## What it is
Portus is an open-source authorization service and web UI for the Docker Registry v2 API, providing fine-grained push/pull permissions via token-based authentication. It supports teams and namespaces, LDAP/OAuth/OpenID Connect login, auditing, search, and security scanning integration for self-hosted registries.

## Use cases
- secure a private docker registry with authentication
- manage team permissions for container images
- self-host a docker registry with a web UI
- add LDAP login to a docker registry
- audit who pushed and pulled container images
- control which users can push or pull docker images

## When to choose
- you run Docker Distribution on-premise and need fine-grained access control
- you want a web interface and audit trail for your private registry
- you need LDAP, OAuth, or OpenID Connect authentication for registry users

## When to avoid
- you need a modern actively developed registry UI - consider alternatives like Harbor or Zot
- you use a registry other than Docker Distribution v2
- you need Kubernetes-native registry features
