arp-sts-keycloak 0.2.2

Keycloak-based dev STS helper for the ARP Standard.

ARP STS Keycloak

Keycloak-based dev STS helper for the ARP Standard. This package provides a small CLI that writes a ready-to-run Keycloak docker compose file plus a preconfigured arp-dev realm with ARP clients.

Quick start

pip install arp-sts-keycloak
arp-sts-keycloak init --output ./arp-keycloak
cd ./arp-keycloak
docker compose up -d

Keycloak will be available at http://localhost:8080.

Default realm

The bundled realm is named arp-dev and includes the following clients:

• arp-dev-cli (public client; device flow)
• arp-daemon (client secret: arp-daemon-secret)
• arp-runtime (client secret: arp-runtime-secret)
• arp-tool-registry (client secret: arp-tool-registry-secret)
• arp-run-gateway (client secret: arp-run-gateway-secret)
• arp-run-coordinator (client secret: arp-run-coordinator-secret)
• arp-composite-executor (client secret: arp-composite-executor-secret)
• arp-atomic-executor (client secret: arp-atomic-executor-secret)
• arp-node-registry (client secret: arp-node-registry-secret)
• arp-selection-service (client secret: arp-selection-service-secret)
• arp-pdp (client secret: arp-pdp-secret)

Each service client is configured for client-credentials flow and includes an audience mapper so the access token aud claim matches the client ID.

Additionally, arp-dev-cli is a public client configured for the OAuth device flow (RFC 8628). The default realm also seeds a dev user for the browser step:

• username: dev
• password: dev

Get a token (client credentials)

curl -sS \
  -X POST \
  http://localhost:8080/realms/arp-dev/protocol/openid-connect/token \
  -d 'grant_type=client_credentials' \
  -d 'client_id=arp-runtime' \
  -d 'client_secret=arp-runtime-secret'

Use the resulting access_token as Authorization: Bearer <token>.

Service configuration hints

• Issuer: http://localhost:8080/realms/arp-dev
• OIDC discovery: http://localhost:8080/realms/arp-dev/.well-known/openid-configuration
• Audience: match the ARP service ID (for example arp-runtime)

Notes

• This package is intended for local development and testing.
• arp-sts-keycloak init writes two files: docker-compose.yml and realm-export.json.
• Use --force to overwrite existing files.
