SPIFFE (protocolsoup-spiffe)

When To Use

Use SPIFFE service for workload identity demonstrations: SVID retrieval, mTLS handshakes, JWT-SVID validation, and certificate rotation.

Runtime Contract

Property	Value
Port	8080
Health	GET /health
Status	GET /spiffe/status
Demo mode	Endpoints return 503 when SPIRE is not connected
Full mode	Requires SPIRE agent socket and SHOWCASE_SPIFFE_ENABLED=true

Key Endpoints

• GET /spiffe/.well-known/spiffe-bundle — trust bundle (JWKS format)
• GET /spiffe/svid/x509 — X.509-SVID
• GET /spiffe/svid/x509/chain — X.509-SVID chain (PEM)
• GET /spiffe/svid/jwt — JWT-SVID
• GET /spiffe/svid/info — SVID metadata
• POST /spiffe/validate/jwt — validate JWT-SVID
• POST /spiffe/validate/x509 — validate X.509-SVID
• GET /spiffe/workload — workload info
• GET /spiffe/trust-bundle — trust bundle info
• POST /spiffe/demo/mtls/call — mTLS demo call
• POST /spiffe/demo/jwt-auth/call — JWT auth demo call
• GET /spiffe/demo/rotation — certificate rotation demo

Configuration

Variable	Required	Default	Description
SHOWCASE_BASE_URL	Yes	http://localhost:8080	External base URL
SHOWCASE_SPIFFE_ENABLED	No	false	Enable full SPIRE-backed mode
SHOWCASE_SPIFFE_SOCKET_PATH	No	unix:///run/spire/sockets/agent.sock	SPIRE agent socket
SHOWCASE_SPIFFE_TRUST_DOMAIN	No	protocolsoup.com	Trust domain for SVID validation
SPIRE_SERVER_ADDRESS	No	spire-server:8081	SPIRE server address (for mTLS demo)

Run (Demo Mode)

Demo mode does not require SPIRE infrastructure. Endpoints return 503 until SPIRE is connected.

docker run -p 8080:8080 \
  -e SHOWCASE_BASE_URL=http://localhost:8080 \
  ghcr.io/parlesec/protocolsoup-spiffe:latest

Run (Full Mode)

Requires the SPIFFE compose overlay or equivalent SPIRE infrastructure.

docker compose -f docker-compose.yml -f docker-compose.spiffe.yml up -d

Operational Notes

• Full mode requires SPIRE agent socket mounted at the configured socket path.
• Keep SPIRE sockets internal and restricted to trusted workloads.
• If SVID checks fail, verify trust domain alignment between agent, server, and registration entries.
• The mTLS and JWT auth demos require a running SPIRE server at SPIRE_SERVER_ADDRESS.
