## What it is
A standalone authentication and authorization server implementing the Docker Registry 2 token-based auth protocol. It issues tokens for Docker registries with pluggable backends including static users, LDAP, OAuth providers (Google, GitHub, GitLab), and SQL/MongoDB databases.

## Use cases
- add authentication to a private docker registry
- secure docker registry with ldap login
- token-based auth server for docker registry 2
- restrict who can push and pull from a private registry
- use google or github sign-in for docker registry access
- fine-grained acl control for docker images

## When to choose
- you run Docker Registry 2 and need real authentication instead of a reverse-proxy hack
- you need per-repository or per-action ACLs for container images
- you want to authenticate registry users against LDAP, a database, or an OAuth provider

## When to avoid
- you use a managed registry like Docker Hub, ECR, GCR, or Harbor that has built-in auth
- you need a general-purpose identity provider or OIDC server rather than a Docker-specific token issuer

## Facets
- artifact type: service
- maturity: active
- function: auth, authorization, http-server
- domain: security, self-hosted
- platform: go, self-hosted
- tags: docker-registry, token-authentication, ldap, oauth, helm-chart, containers, devops, docker, kubernetes, linux
