This commit introduces several core configurations and structural improvements:
* **User Management:** Creates a new `iklim` administrative user with a securely hashed password, enabled by `python3-passlib`.
* **System Configuration:** Sets the system keyboard layout to Turkish Q (`trq`).
* **Security Hardening:** Refines firewall rules for SSH using a rich rule and ensures `journald` log limits file creation.
* **Ansible Variable Management:** Restructures `group_vars` by consolidating global variables into `group_vars/all/vars.yml` and sensitive data into a dedicated `group_vars/all/vault.yml`.
* **Ansible Compatibility:** Adds `!unsafe` to a `docker info` shell command to prevent future warnings.
This commit introduces the foundational Ansible playbooks, roles, and configurations for automated provisioning of both production and test environments.
Key capabilities include:
- **Base System Setup:** Common packages, timezone, chrony, and hostname.
- **Security Hardening:** SELinux disable, SSH configuration, `dnf-automatic`, `fail2ban`, `firewalld` setup, and `journald` log limits.
- **Docker & Swarm:** Docker installation and configuration, Docker Swarm initialization/joining for managers and workers, overlay network creation, and node labeling.
- **Storage:** Hetzner StorageBox integration using `davfs2`.
- **Directory Structure:** Creation of application and database-specific directories.
This establishes a comprehensive, automated pipeline for infrastructure deployment and initial configuration.
