API & Authentication

API Architecture

API v1 (endpoints/api/): REST API for UI and programmatic access

Flask-based with resource decorators
Session-based auth with CSRF tokens
Endpoints return JSON

API v2 (endpoints/v2/): OCI/Docker Registry Protocol

JWT bearer token authentication
Implements Docker Registry HTTP API V2
Scope-based access control

Testing API v1 (Session Auth)

# 1. Get CSRF token and establish session
CSRF_TOKEN=$(curl -s -c cookies.txt -b cookies.txt "http://localhost:8080/csrf_token" | jq -r '.csrf_token')

# 2. Sign in
curl -s -c cookies.txt -b cookies.txt -X POST \
  -H "Content-Type: application/json" \
  -H "X-Requested-With: XMLHttpRequest" \
  -H "X-CSRF-Token: $CSRF_TOKEN" \
  -d '{"username": "admin", "password": "password"}' \
  "http://localhost:8080/api/v1/signin"

# 3. Use session cookies for API calls
curl -s -b cookies.txt "http://localhost:8080/api/v1/user/"

Note: Basic auth does NOT work with local dev for API v1.

Testing API v2 (JWT Bearer Tokens)

# Get bearer token
TOKEN=$(curl -s -u username:password "http://localhost:8080/v2/auth?service=localhost:8080" | jq -r '.token')

# Use for v2 calls
curl -s -H "Authorization: Bearer $TOKEN" "http://localhost:8080/v2/_catalog"

# With specific scope
TOKEN=$(curl -s -u username:password \
  "http://localhost:8080/v2/auth?service=localhost:8080&scope=repository:namespace/repo:pull" \
  | jq -r '.token')

Adding API v1 Endpoints

Add endpoint to file in endpoints/api/

Use appropriate decorators:

from endpoints.api import resource, nickname, require_repo_read

@resource('/v1/repository/<namespace>/<repository>/example')
class RepositoryExample(RepositoryParamResource):
    @require_repo_read(allow_for_global_readonly_superuser=True)
    @nickname('getExample')
    def get(self, namespace, repository):
        # Implementation

Create model interface in *_models_interface.py
Implement model in *_models_pre_oci.py
Add tests in endpoints/api/test/ or test/

Permission Decorators

# Repository permissions
@require_repo_read(allow_for_global_readonly_superuser=True)
@require_repo_write
@require_repo_admin

# User permissions
@require_user_admin
@require_fresh_login

# Superuser
@require_scope(scopes.SUPERUSER)
