 # HellreigN
+
+Агент внутренней диагностики инфраструктуры. Централизованный сбор логов, мониторинг нагрузки, управление скриптами и контроль состояния сервисов.
+
+## Возможности
+
+- **Сбор логов** — journald, Docker, Kubernetes, файлы
+- **Метрики нагрузки** — CPU, RAM, диск, сеть в реальном времени
+- **Контроль сервисов** — проверка alive/dead для systemd и Docker
+- **Удалённое выполнение команд** — запуск скриптов и команд на агентах
+- **Граф зависимостей** — определение причин сбоев, порядок запуска
+- **Офлайн-буфер** — логи не теряются при потере связи
+- **mTLS** — защищённое соединение между агентом и бэкендом
+
+## Архитектура

+
+## Быстрый старт
+
+### Требования
+
+- Docker + Docker Compose
+- Go 1.26.1+ (для локальной разработки)
+
+### Деплой
+
+```bash
+cd infra
+docker compose up -d --build
+```
+
+Поднимутся:
+- **ClickHouse** — хранилище логов
+- **Backend** — API (`8080`) + gRPC (`9001`)
+- **Frontend** — веб-интерфейс (`3000`)
+- **Agent** — пример агента
+
+Откройте `http://localhost:3000`. Логин: `admin`, пароль: `admin123`.
+Что бы агент заработал нужно в веб интрфейсе найти кнопку создать токен получить его и вписать в конфигурацию агента
+### Локальная разработка
+
+```bash
+# Backend
+cd backend && go run ./cmd/main.go
+
+# Frontend
+cd frontend && npm install && npm run dev
+
+# Agent
+cd agent && CONFIG_FILE=./config.yml go run main.go
+```
+
+## Конфигурация
+
+### Backend
+
+`infra/backend/config.yml`:
+
+```yaml
+database:
+  token_db: /var/lib/hellreign/tokens.db
+  clickhouse_host: clickhouse:9000
+  clickhouse_user: default
+  clickhouse_password: testpassword
+  clickhouse_database: hellreign
+admin:
+  admin_name: Admin
+  admin_last_name: User
+  admin_login: admin
+  admin_password: admin123
+```
+
+### Агент
+
+`infra/agent/config.yml`:
+
+```yaml
+backend_url: http://backend:8080
+grpc_url: backend:9001
+label: production-server-1
+registration_token: "token-из-ui"
+cert_dir: /etc/hellreign-agent/certs
+services:
+  # journald + проверка systemd
+  - name: nginx
+    type: journald
+    systemd_unit: nginx.service
+
+  # Docker контейнер
+  - name: redis
+    type: docker
+
+  # Файл
+  - name: myapp
+    type: file
+    path: /var/log/myapp/app.log
+```
+
+Поле `systemd_unit` опционально. Если указано — агент проверяет `systemctl is-active` и шлёт статус `up`/`down`. Для Docker — `docker inspect {{.State.Running}}`.
+
+### Граф зависимостей
+
+`infra/services.yaml`:
+
+```yaml
+nodes:
+  production-server-1:
+    services:
+      nginx:
+        depends_on: [sshd]
+      sshd:
+        depends_on: []
+```
+
+Используется для определения причины сбоев и порядка запуска.

+
+## Деплой агента на хост
+
+### 1. Директории
+
+```bash
+sudo mkdir -p /etc/hellreign-agent/certs /var/lib/hellreign-agent
+```
+
+### 2. Конфиг
+
+```bash
+sudo nano /etc/hellreign-agent/config.yml
+```
+
+```yaml
+backend_url: https://monitoring.example.com
+grpc_url: monitoring.example.com:9001
+label: prod-web-1
+registration_token: "token-из-ui"
+cert_dir: /etc/hellreign-agent/certs
+services:
+  - name: nginx
+    type: journald
+    systemd_unit: nginx.service
+  - name: postgres
+    type: journald
+    systemd_unit: postgresql.service
+```
+
+### 3. Бинарь
+
+Скачать из релиза Gitea или собрать:
+
+```bash
+cd agent && go build -o hellreign-agent ./main.go
+sudo mv hellreign-agent /usr/bin/
+```
+
+### 4. Systemd
+
+```ini
+[Unit]
+Description=HellreigN Agent
+After=network-online.target
+
+[Service]
+Type=simple
+ExecStart=/usr/bin/hellreign-agent
+Environment=CONFIG_FILE=/etc/hellreign-agent/config.yml
+Restart=always
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable --now hellreign-agent
+```
+
+## CI/CD
+
+При пуше тега `v*` — GoReleaser собирает `.deb` и `.rpm` для `linux/amd64` и `linux/arm64`:
+
+```bash
+git tag v1.0.0 && git push origin v1.0.0
+```
+
+Требует секрет `GITEA_TOKEN` в настройках репозитория.
+
+## Proto
+
+После изменений в `proto/hellreign.proto`:
+
+```bash
+cd proto
+protoc --go_out=. --go_opt=paths=source_relative \
+       --go-grpc_out=. --go-grpc_opt=paths=source_relative \
+       hellreign.proto
+mv hellreign*.go proto/
+```
