- Create Redis data directory with correct ownership (UID 999) so Redis
can write RDB snapshots; root-owned directory caused stop-writes-on-bgsave-error
which crash-looped Nextcloud background jobs at 400%+ CPU
- 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
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
