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

Configuration Runbook

First-run configuration steps to perform after the Ansible playbook has provisioned the server. See runbook-provisioning.md for the provisioning steps.

Gitea

gitea_disable_registration defaults to true. For the first deploy, override it to false so the setup wizard can create the admin account:

ansible-vault edit ansible/group_vars/all/vault.yml
# add: gitea_disable_registration: false
ansible-playbook -i ansible/inventory.ini ansible/site.yml --tags gitea --ask-vault-pass

After the admin account is created at https://gitea.ladkau.de, remove the override and redeploy to close public registration.

Keycloak

KEYCLOAK_ADMIN / KEYCLOAK_ADMIN_PASSWORD bootstrap the initial admin account on first start only — Keycloak ignores them once the account exists. After logging in at https://sso.ladkau.de, change the admin password via the UI.

Keycloak takes ~90 seconds to start. If the login page is not immediately available, wait and retry.

Nextcloud

Nextcloud runs its first-time installation on the initial HTTP request, which takes a minute or two. The admin credentials are set via nextcloud_admin_user and nextcloud_admin_password in the vault.

Roundcube

Roundcube is a webmail client — it does not host mail itself. Configure the IMAP and SMTP servers it connects to via ansible/group_vars/all/vars.yml:

roundcube_imap_host: "ssl://mail.example.com"  # implicit TLS (port 993)
roundcube_smtp_host: "mail.example.com"         # STARTTLS (port 587)

Leave both empty to let users enter their own server at login.

Container registry

# Login
docker login cr.ladkau.de

# Push
docker tag myimage:latest cr.ladkau.de/myimage:latest
docker push cr.ladkau.de/myimage:latest

# Pull
docker pull cr.ladkau.de/myimage:latest

Registry credentials are managed via registry_htpasswd in the vault. To add or rotate a user, regenerate the htpasswd entry and redeploy:

docker run --entrypoint htpasswd httpd:2 -Bbn <user> <password>
# update registry_htpasswd in vault, then:
ansible-playbook -i ansible/inventory.ini ansible/site.yml --tags registry --ask-vault-pass
