This commit brings the `README.md` and Ansible setup guides (`03-test-ansible-bootstrap.md`, `07-prod-ansible-bootstrap.md`) in sync with the current state of the Ansible automation.
Key updates include:
- Acknowledging the presence of in-repository Ansible playbooks and shared roles.
- Correcting Ansible inventory output paths and Terraform output commands.
- Detailing the new `group_vars/all/{vars.yml,vault.yml}` structure.
- Updating Ansible prerequisites to include `passlib` for password hashing.
- Adding documentation for `iklim` system user creation, keyboard layout, and refined firewall rules.
- Removing outdated "Known Gaps" related to missing Ansible code.
Adjusts documentation for test and production Ansible bootstrapping to leverage `ansible.cfg`. Commands are now run from specific environment directories (`ansible/test/` or `ansible/prod/`), eliminating the need to explicitly specify inventory and playbook paths.
Also adds an initial step to install required Ansible collections using `ansible-galaxy`.
This commit introduces a reordered and renumbered set of setup documentation files to better reflect the deployment stages for both test and production environments.
Key changes include:
* A new `setup-vs-roadmap-map.md` file to provide a clear mapping between roadmap tasks and their corresponding setup phases.
* Significantly expanded Ansible bootstrap documentation for both test and production, detailing Docker, Swarm, security hardening, and StorageBox SSH key management roles.
* Formalized database Docker and Swarm cluster setup instructions for test and production, including explicit steps for Swarm worker integration of DB nodes.
* Updated roadmap documentation (`roadmap/prod-env/*`) to align with the refined setup, incorporating correct private IP addresses for Swarm joins, new node labels, and floating IP usage for GoDaddy DNS records.
- Add `hetzner-sizing-report.md` defining data-driven server type recommendations for test and prod environments.
- Update Terraform configurations to align with the recommended `CPX` server types and refine firewall rules for Docker Swarm and database interactions.
- Introduce comprehensive documentation and stack files for:
- Single-node PostgreSQL/MongoDB deployment on a test DB worker node.
- High-availability 3-node MongoDB replica set and Patroni+etcd PostgreSQL cluster for production.
- Enhance Ansible bootstrap roles with SELinux disabling, fail2ban configuration, and StorageBox SSH key management for CI/CD.
- Reorganize and rename setup documentation files for improved structure and clarity.
