## Overview

#### Purpose and entry points

This repository provides a default Nginx configuration. Its operational entry point is the Nginx process loading `nginx.conf`; there is no application runtime, source build, or service code in the repository.

Relevant paths:
- `nginx.conf`
- `README.md`

#### Nginx configuration boundary

`nginx.conf` is the architecture-defining artifact. It controls how Nginx listens for requests, selects virtual servers, serves or proxies content, and applies HTTP/TLS, logging, caching, and upstream-routing behavior as configured.

Relevant path:
- `nginx.conf`

#### Request-processing flow

At runtime, inbound network traffic reaches Nginx, which evaluates directives in `nginx.conf` through its standard configuration hierarchy: global process settings, event handling, HTTP configuration, server selection, and location matching. The selected location determines the terminal action, such as static-file delivery, reverse proxying, redirects, or access denial.

Relevant path:
- `nginx.conf`

#### Runtime and infrastructure

The required runtime is Nginx deployed on a host, container, or orchestration environment that mounts or installs this configuration. Network listeners, filesystem paths, certificates, log destinations, and any proxied upstreams are external infrastructure dependencies defined or referenced by the configuration.

Relevant paths:
- `nginx.conf`
- `README.md`

#### Operational ownership

Changes should be treated as infrastructure changes: configuration syntax must be validated by Nginx before reload, and deployment must safely reload the running Nginx service. There are no repository-defined automation, tests, application APIs, or data stores visible in the provided tree.

Relevant paths:
- `nginx.conf`
- `1.txt`

Main entry points: [`nginx.conf`](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/nginx.conf) (nginx.conf), [`README.md`](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/README.md) (README.md)

## Components

### Nginx Runtime

Nginx loads the repository configuration in deployed infrastructure.

- **Nginx process**: runtime · Loads configuration and handles inbound traffic.
- **Terminal action**: request handling · Serves files, proxies, redirects, or denies access.

### Configuration Hierarchy

Directives govern request handling from process scope through locations.

- [nginx.conf](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/nginx.conf): Nginx configuration · Architecture-defining Nginx configuration artifact. · `nginx.conf`
- [Global settings](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/nginx.conf): configuration scope · Controls Nginx process-level behavior. · `nginx.conf`
- [Event handling](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/nginx.conf): configuration scope · Controls connection event processing. · `nginx.conf`
- [HTTP settings](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/nginx.conf): configuration scope · Defines HTTP, TLS, logging, caching, and routing behavior. · `nginx.conf`
- [Virtual server selection](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/nginx.conf): configuration scope · Selects a server based on the listener and request host. · `nginx.conf`
- [Location matching](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/nginx.conf): configuration scope · Matches request paths to a terminal action. · `nginx.conf`

### External Infrastructure

Dependencies are installed, mounted, or referenced outside this repository.

- **Inbound traffic**: network requests
- **Filesystem content**: external dependency · Static content and configured filesystem paths.
- **Proxied upstreams**: external dependency · Backend services referenced by reverse-proxy rules.
- **Certificates and logs**: external dependency · TLS material and configured log destinations.
- **Host or container deployment**: infrastructure · Installs or mounts the configuration and safely reloads Nginx.

### Other components

- [README.md](https://github.com/vmakar2160/rebrain-devops-task1/blob/main/README.md): documentation · Repository usage and operational guidance. · `README.md`
