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 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- Removing outdated "Known Gaps" related to missing Ansible code.
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.
This commit systematically updates all Terraform configurations, including resources, variables, and labels, to use the more generic `app` designation instead of `swarm`. This improves consistency and decouples the infrastructure naming from a specific container orchestration technology like Docker Swarm.
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.
This new README serves as the central documentation for the `iklim.co` Hetzner Cloud environment infrastructure repository. It outlines the project's purpose, scope, and structure, alongside detailed setup guides, security baselines, environment topologies, and usage instructions for Terraform.
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.
- 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.
- Database nodes now join the Docker Swarm as workers with `role=db` labels, allowing Swarm to manage their dedicated services.
- The `docker-stack-infra.yml` has been updated for production to focus solely on application-level infrastructure components.
- Dedicated database services (PostgreSQL, MongoDB, Patroni-etcd) are now explicitly deployed in separate Swarm stacks on `iklim-db-XX` nodes.
- Standardizes node naming conventions (`iklim-app-XX`, `iklim-db-XX`) across the production roadmap documentation.
- Clarifies that the `etcd` service within `docker-stack-infra.yml` is exclusively for APISIX configuration, distinct from Patroni's etcd cluster.
- This commit introduces the Terraform configuration to provision a production environment on Hetzner Cloud, building on the existing test setup.
- Key improvements and new features include:
* **Multi-node clusters:** Scaling to 3-node Swarm application and database clusters for improved resilience.
* **High availability:** Utilizing a Hetzner Floating IP for the application entry point and `spread` placement groups for fault tolerance across physical hosts.
* **Enhanced network security:** Internal management services (RabbitMQ, APISIX, Prometheus, Grafana) are restricted to the application subnet, expected to be accessed via an internal reverse proxy (SWAG).
* **Internal database replication:** New firewall rules enable PostgreSQL replication and MongoDB replica set traffic within the database subnet.
* **Refined test environment:** Updates to align `test` configuration with the new `prod` structure, including a dedicated floating IP and adjusted firewall rules.
* **Configuration standardization:** Environment-specific details moved to `locals.tf` for clarity, with upgraded server types and migration to Rocky Linux as the base image.
- Updates were also made to the latest version of Terraform to ensure consistency in the documentation
This commit introduces the foundational Infrastructure-as-Code for provisioning a test environment on Hetzner Cloud. It defines server nodes, private networking, comprehensive firewalls, and includes documentation on resource lifecycle and safe configuration practices.
