From 8b5c2395b5b88f180e11afbf59d900d30be7ff0d Mon Sep 17 00:00:00 2001 From: Chris Coutinho Date: Fri, 27 Feb 2026 20:33:54 +0100 Subject: [PATCH] feat: add Docker Compose profiles and Login Flow v2 service MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add selective service startup via Docker Compose profiles so each MCP deployment mode runs independently. Also add the new mcp-login-flow service (port 8004) for Login Flow v2 authentication (ADR-022). Profile assignments: - single-user: mcp (port 8000) - multi-user-basic: mcp-multi-user-basic (port 8003) - oauth: mcp-oauth (port 8001) - keycloak: keycloak + mcp-keycloak (port 8002) - login-flow: mcp-login-flow (port 8004) Infrastructure services (db, redis, app, recipes) always start. Integration tests cover the full Login Flow v2 provisioning flow: OAuth → browser login → app password → Nextcloud API access for notes, calendar, contacts, files, deck, and cookbook operations.
