Add oauth2-proxy (GitHub provider, org-restricted) as a reverse proxy in front of the dsh-gateway, wired through the Traefik Gateway API. The gateway inherits the authenticated GitHub username via X-Forwarded-User (SSO). - gateway.py: opt-in AUTH_PROXY_HEADER trust, remote_user(), SSO bootstrap (auto-provision claim + mint/rotate token + session cookie), patch_token() - 50-gateway.yaml: AUTH_PROXY_HEADER=X-Forwarded-User, COOKIE_SECURE=true - gateway-api/dsh-demo: oauth2-proxy Deployment/Service + secret example, HTTPRoute backend -> oauth2-proxy:4180 - tests: 10 new SSO cases (106 passing) Placeholders (dsh-demo.example.com, your-github-org) are substituted at apply time.

# oauth2-proxy — GitHub OAuth login in front of the dsh-gateway.
|
|
#
|
|
# Runs as a reverse proxy: it authenticates the browser against GitHub
|
|
# (restricted to a configured organization), then forwards the request to
|
|
# the dsh-gateway Service with the authenticated identity in X-Forwarded-User
|
|
# (plus X-Auth-Request-* via --set-xauthrequest). The gateway trusts that
|
|
# header (AUTH_PROXY_HEADER) to inherit the username (SSO).
|
|
#
|
|
# Credentials come from the "oauth2-proxy" Secret (see
|
|
# oauth2-proxy-secret.yaml.example); this manifest never carries secrets.
