ml b15754ba2f Harden against bot floods and add post-provisioning service check
- Traefik rate-limits all routes (60 req/min standard, 300 for Nextcloud)
  and writes access logs to /var/log/traefik/access.log
- Fail2ban watches Traefik access logs and bans IPs after 10 x 403/404
  within 60 s for 24 h
- Nextcloud html directory created as www-data (UID 33) so Apache can
  process .htaccess and serve requests correctly
- scripts/check-services.sh verifies all seven endpoints return the
  expected HTTP status after provisioning

ml e197ba7370 Fix all issues found during first live provisioning run
Traefik:
- Upgrade v3.3 → v3.6 to fix Docker API version negotiation failure
  with Docker Engine 29 (which dropped support for API < 1.40)

Directory permissions:
- Change all service parent directories from 0750 to 0755 so container
  processes can traverse them after dropping from root to a lower UID
- Create db directories owned by postgres UID 999 (mode 0700) so
  PostgreSQL can access its data files across Ansible runs
- Create /opt/gitea/data owned by git UID 1000 (Gitea writes there
  after dropping privileges)

Healthchecks:
- Fix Redis healthcheck: use CMD form instead of CMD-SHELL pipe
  (pipe was unreliable in Alpine)
- Fix Keycloak healthcheck: use bash /dev/tcp on management port 9000
  (curl not available in UBI image; was incorrectly targeting port 8080)

Image tags:
- Fix Roundcube: 1.6 and 1.6-apache do not exist; correct tag is 1.6.x-apache

Bootstrap scripts:
- bootstrap-deploy-user.sh: add sudoers.d entry for passwordless sudo
  (deploy user has no password so sudo group alone was not enough)
- run-bootstrap.sh: read server IP from inventory.ini, chmod 600 keys
  automatically, show actual SSH error on failure

Inventory / config:
- Add ansible_host to inventory.ini — server IP now defined in one place
- Restructure group_vars/ into all/ directory so vault.yml is
  auto-loaded (previously it did not match any group name)
- Move ansible.cfg to repo root (Ansible looks in cwd, not playbook dir)

Docs:
- Split runbook.md into runbook-provisioning.md and
  runbook-configuration.md
- Add step 1 (set server IP) to provisioning runbook
- Expand prerequisites with SSH key generation and upload instructions
- Expand bootstrap step with preflight check details

ml a462ff1729 Fix provisioning errors found during first real run
- ansible.cfg: suppress Python interpreter discovery warning
- ansible/inventory.ini: add ansible_host; server IP is now defined in
  one place and read dynamically by run-bootstrap.sh
- group_vars/all/ → directory layout so vault.yml is auto-loaded by Ansible
  (previously vault.yml did not match any group name and was silently ignored)
- scripts/run-bootstrap.sh: read server IP from inventory, chmod 600 private
  keys automatically, show actual SSH error when root login fails
- scripts/bootstrap-deploy-user.sh: add sudoers.d entry for passwordless sudo
  (deploy user has no password so sudo group membership alone was not enough)
- nextcloud: fix Redis healthcheck (CMD-SHELL pipe was unreliable in Alpine,
  switched to CMD form with start_period)
- group_vars/all/vars.yml: fix Roundcube image tag (1.6-apache and 1.6 do not
  exist; correct tag is 1.6.x-apache)
- docs/runbook.md: expand prerequisites (SSH keys section), add step 1 for
  setting the server IP, expand bootstrap step with preflight detail, fix
  step numbering
2026-06-28 05:53:29 +02:00
ml 03d2f6d57a Add bootstrap scripts and restructure runbook
- scripts/run-bootstrap.sh: copies and runs the deploy user bootstrap on a
  fresh server, verifies SSH login, checks vault as a preflight step
- scripts/bootstrap-deploy-user.sh: runs on the server as root, accepts the
  SSH public key as an argument (read from keys/ by run-bootstrap.sh)
- scripts/check-vault.sh: decrypts vault.yml and verifies all 11 required
  secrets are present and non-empty
- docs/runbook.md: restructured into correct order (collections → DNS → vault
  → bootstrap → playbook), added scripts reference table, moved first-run
  notes for Gitea/Keycloak/registry into their own section
- README.md: added scripts/ to repo layout
2026-06-28 05:03:05 +02:00
ml 75a0f21f74 Implemented all service roles
- docker: install Docker Engine from official apt repo, configure log rotation,
  create shared traefik_public network
- traefik: reverse proxy with automatic Let's Encrypt TLS, dashboard on
  cloud.ladkau.de behind basic auth
- gitea: self-hosted Git with PostgreSQL, Git-over-SSH on port 2222
- sso: Keycloak with PostgreSQL for OIDC/OAuth2 single sign-on
- nextcloud: file storage with PostgreSQL, Redis, cron sidecar, CalDAV/CardDAV
  well-known redirects
- mail: Roundcube webmail client with PostgreSQL
- registry: Docker Registry v2 with htpasswd auth, no upload size limit
- k8s: placeholder nginx page

All secrets documented in vault.yml; runbook updated with per-service
first-run notes.

ml 6115d9d48f Set up repo structure and implement base role
- Document architecture decisions in README (Ansible + Docker Compose + Traefik)
- Scaffold Ansible layout: inventory, site.yml, group_vars, 9 service roles
- Implement base role: package install, deploy user, SSH hardening,
  UFW firewall (22/80/443), fail2ban, unattended-upgrades
- Add reinstall runbook in docs/runbook.md
- Add ansible/requirements.yml for community.general and ansible.posix
