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.
Overhaul and expand firewall definitions for both `prod` and `test` environments to enable comprehensive inter-subnet communication.
This includes implementing explicit rules supporting:
- Docker Swarm overlay networks between application and database subnets.
- High-availability database clusters (PostgreSQL replication, MongoDB replica sets, Patroni, etcd).
- Internal access for various infrastructure services (Vault, Redis, RabbitMQ, APISIX, Prometheus, Grafana).
All firewall rule descriptions are standardized in English for improved clarity and consistency.
Additionally, update default `server_type_swarm` and `server_type_db` variables to the recommended `CPX` series for both environments. An initial generated Ansible inventory for the test environment is also added.
