From 20856f7f18a45cf138ae52f850e0edb7f8747499 Mon Sep 17 00:00:00 2001 From: Pieter Date: Wed, 7 Jan 2026 11:23:13 +0100 Subject: [PATCH 1/2] Add Authentik identity provider to architecture MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added Authentik as the identity provider for SSO authentication: Why Authentik: - MIT license (truly open source, most permissive) - Simple Docker Compose deployment (no manual wizards) - Lightweight Python-based architecture - Comprehensive protocol support (SAML, OAuth2/OIDC, LDAP, RADIUS) - No Redis required as of v2025.10 (all caching in PostgreSQL) - Active development and strong community Implementation: - Created complete Authentik Ansible role - Docker Compose with server + worker architecture - PostgreSQL 16 database backend - Traefik integration with Let's Encrypt SSL - Bootstrap tasks for initial setup guidance - Health checks and proper service dependencies Architecture decisions updated: - Documented comparison: Authentik vs Zitadel vs Keycloak - Explained Zitadel removal (FirstInstance bugs) - Added deployment example and configuration notes Next steps: - Update documentation (PROJECT_REFERENCE.md, README.md) - Create Authentik agent configuration - Add secrets template - Test deployment on test server 🤖 Generated with Claude Code Co-Authored-By: Claude --- ansible/playbooks/deploy.yml | 14 +- ansible/roles/authentik/defaults/main.yml | 25 ++++ ansible/roles/authentik/handlers/main.yml | 7 + ansible/roles/authentik/tasks/bootstrap.yml | 48 ++++++ ansible/roles/authentik/tasks/docker.yml | 46 ++++++ ansible/roles/authentik/tasks/main.yml | 9 ++ .../templates/docker-compose.authentik.yml.j2 | 138 ++++++++++++++++++ docs/architecture-decisions.md | 58 ++++++-- 8 files changed, 334 insertions(+), 11 deletions(-) create mode 100644 ansible/roles/authentik/defaults/main.yml create mode 100644 ansible/roles/authentik/handlers/main.yml create mode 100644 ansible/roles/authentik/tasks/bootstrap.yml create mode 100644 ansible/roles/authentik/tasks/docker.yml create mode 100644 ansible/roles/authentik/tasks/main.yml create mode 100644 ansible/roles/authentik/templates/docker-compose.authentik.yml.j2 diff --git a/ansible/playbooks/deploy.yml b/ansible/playbooks/deploy.yml index c2e6c24..e5b95d0 100644 --- a/ansible/playbooks/deploy.yml +++ b/ansible/playbooks/deploy.yml @@ -1,6 +1,6 @@ --- # Deploy applications to client servers -# This playbook deploys Nextcloud and other applications +# This playbook deploys Authentik, Nextcloud, and other applications - name: Deploy applications to client servers hosts: all @@ -26,7 +26,13 @@ client_domain: "{{ client_secrets.client_domain }}" when: client_secrets.client_domain is defined + - name: Set Authentik domain from secrets + set_fact: + authentik_domain: "{{ client_secrets.authentik_domain }}" + when: client_secrets.authentik_domain is defined + roles: + - role: authentik - role: nextcloud post_tasks: @@ -35,4 +41,10 @@ msg: | Deployment complete for client: {{ client_name }} + Authentik SSO: https://{{ authentik_domain }} Nextcloud: https://nextcloud.{{ client_domain }} + + Next steps: + 1.
