Document and commit the production bootstrap state after the initial Hetzner and Ansible rollout.
- switch Ansible prod runbooks to use the shared vault password file
- record production admin CIDRs, SSH key path, encrypted group vault, and encrypted per-host vault files
- add generated production inventory and the prod setup history notes from the first bootstrap
- keep root password login disabled while preserving key-based root access for Ansible bootstrap continuity
- document separate Hetzner projects and tokens for test/prod and commit the prod provider lock file
- remove the private Redis firewall allowance from the prod Terraform firewall and matching setup docs
Add the Ansible README and expand prod bootstrap coverage for StorageBox keys, DB labels, DB stack configuration, and act runner setup. Update MongoDB configuration for replica set support and refresh prod roadmap/setup documentation for Swarm labels, StorageBox-backed cert paths, and recovery guidance.
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.
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.
- 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
